E. Track operating area	Can be presented, all operating tracks. For each track, you can edit

3、Material library introduction

Definition
Store and display all the materials in production. Currently supports import formats, including JPG, PNG, CAF and other formats. In a filter, use related materials. First import the material library, and then add to the track from the material library. (Knowledge 1-CAF)
Function
Add	Click the [+Add] button to import one or more local pictures into the material library
View	Click on the imported material, preview the material at the top, and understand the resolution and size of the material
Delete	After clicking the material, click the [Delete] button to delete it from the material library. Shortcut key: [Delete]. PS: If the material has been applied in the track, it will not be affected by deleting it from the material library.
Drag	Drag the material to the track to apply

4、Introduction to Track Panel

Definition

The track panel is the core part of this tool. The material is placed on the track and operated to form a filter package. Meishe special effects tool, its track format, followed the mainstream video packaging software. The difference is that there is a preview track in the Meishe track, which is fixed at the bottom of the track panel. The role is to simulate the input source (video screen and imported video, etc.) when the user uses it. If the video screen itself is processed, use the method of [add reference: 1 input source]. Later, each part will be introduced step by step.

4.1、Multi-frame filter production

Description

This tool makes various filter forms such as color tones, borders, foregrounds, and special effects. It should be noted that for borders and foreground animation filters, different frames, styles and expressions may be different. So it needs to be produced in multiple formats. Currently supports the following 7 formats such as 16:9/9:16/1:1. Each frame is made independently, and finally forms a filter package, which contains filters for multiple frames. If you only write a few of them, the final special effects package will only contain the tracks you wrote (Knowledge 2-frame adaptation)

4.2、Preview track

Description
Input source track is a unique concept of Meishe SDK,, unique concepts, and simulate the role of content input sources, allowing you to see the effect more clearly. It can't directly apply special effects. If special effects are needed, process the picture itself and add reference tracks to realize it. After quoting, there will be a track that can be edited. Add toning, distortion, etc. on this. If you want to achieve effects such as split screen, you can quote multiple times. Preview the track and adjust the screen size to achieve the effect. A. Generally, Input source track needs to be input, and the application effect is not added, and the screen cannot be seen. B. Multiple input source tracks can be added. In actual application, the same video content will be displayed. C. The input source track defaults to 4S. If you need the same filter and display the video screen, you need to set the loop.
Operating
1. Add reference track	Turn the user's input source into an editable reference track, just like a normal track
2. Replace the video	Replace the video or photo, as the input source, preview, only play a preview role. In the actual filter no added。
3. Background on/off	Whether to display the bottom of the track when applying filter effects. The input source video, if there is already a full-screen reference track, can be closed. After closing, the filter effect will not be affected, and the efficiency will be improved. For the same reason, if the background is turned off, the actual filter material does not cover the full screen. When the filter is applied, you will see that the background is black

4.3、Track operation

Description

The overall design of the track is similar to mainstream video production tools. On the left is the information and special effects operations of each track; on the right is the track timeline part. The following is a step-by-step introduction, the function of track operation

Overall operation of the left area
1.Select the frame	Select the top frame, each frame is independent and will not affect each other.
2. Add track	Drag one from the material library to add a track to the material. You can also click on the preview track below to add one and enter the source track
3. Add input source track	Click [Add input source track] to add, there is no difference between the input source track and the normal track, and all the operations of the track can be performed.
4. Replace the video	Click [Replace Video], select local video, simulate input screen for preview, replace all input source tracks, and present the same content. The purpose of this function is to facilitate the preview, and the exported filter package does not contain the video.
5. Add music	You can add a piece of music for use in the preview. If the final output is an album package during production, the added music will be automatically exported into the background music of the album.
6.Delete the track	Select a track and click [Delete] to delete, or right click on the selected track to delete
7. Rename track	Click [Select Track] to rename the track for easy viewing in editing.
8.Show/hide tracks	Click the [eye] button in front to show or hide the track. Hidden tracks will not appear in the material package during final output
9.Special effects expand/collapse	After clicking the arrow in front of the name, expand or collapse the special effects on each track. Each track has a default transformation, and ALPHA channel map effects, which cannot be deleted. Other special effects. After selecting the track, add it in the effect panel on the right side of the preview window. Please refer to the concept of Alpha channel (Knowledge 3-alpha channel)
10.Remove trick	Select the trick on the track, right click to delete it, or click [Delete] to delete.
11.Cycle parameters	In some special effects productions such as filters, there are often parameters for looping. For example: snow falling back and forth, decorations in reciprocating motion, etc. Since it is not possible to predict the actual duration of the filter, it is necessary to set a loop for some reciprocating tracks. The default is not loop, and it can be modified to loop. After setting, according to the current setting, the loop will be played. At the same time, the interval time of each cycle can be set.
12.Overlay method	There are many ways to superimpose the track of Meishe, which can be set. The default is standard, and there are multiply, subtract, filter, add, and exclude
13.CAF cycle setting	CAF is a kind of sequence frame animation used by Meishe in the material package. When using CAF as a track, if the current track length is greater than its own CAF length, it needs to be set 1. None: the sequence animation will be played only once 2. Default: use the loop mode set in the CAF format 3. Repeat: the sequence animation will be played repeatedly 4. Mirroring: the sequence animation will be played back and reverse again, and so on 5. Repeat the last frame: the sequence animation will be played once, and then continue to play the last frame
14. Size	The size setting is the size of the currently imported track and material. The default is the size of the file itself. If you need to perform operations such as stretching, you need to change it. For example: You want to add a white background to cover the full screen without importing a white picture and zooming in. Instead, import it directly, a small picture of a few pixels, and then set the picture size to the length and width of the current frame, so that's it (the default frame is 720P, for example, 16:9 is 1280X720)
15. Add group	In the blank space of the track, right-click to add a group, which is a virtual concept. Bind some tracks to the group and follow the group to move
16.Group connection	Each track can be added to a group, the track is in the order, only below the group
17.Sort	Drag the track, you can do it, sort the track up and down
18. Curve switch	The track area on the right becomes the curve mode, showing the curve of the currently selected trick.
19. Expand/Collapse All	Click the button in the lower left corner to expand/collapse all trick.

Track editing operations
1.Duration cutting	Modify the duration of the track by dragging the in and out points of the track
2.Drag the track position	Press and hold the timeline on the right to drag the track
3.Special effects editor	After unfolding a track, you can see all the special effects in the track, drag or input the value of the special effect to perform the corresponding special effect operation.
4.Keyframe	Click the [Stopwatch] function before the effect to start the Keyframe of the effect. The operation is similar to AE, drag to the corresponding position, modify the value, and keyframe the special effect. The current special effects tool supports linear keyframes. The next version will add curve keyframes.
5.Step frame	Step frame is a special effect definition. Generally speaking, special effects packages are produced at 25 frames per second. But on the mobile terminal, video preview, or output, there may be 30 frames per second. When playing, something will happen. Although the Keyframe animation is switched between two frames in the special effect design, the actual number of playing frames has increased. For example, when changing, the middle screen appears. In order to avoid this situation, stepping frames are added between the frame animations so that some jump effects can appear. Specific operation: Select a Keyframe, right-click, and the [Add Step Frame] button will pop up. After adding, enter the step value, it will ensure that the step effect will appear in any case when playing the animation
6.Special effects add files	In each special effect, special effects such as AlphaPatten and LUT can be realized only by importing the corresponding file. Among them, LUT special effects need to be imported, the MSLUT file of Meishe (Knowledge 4-LUT file)
7. Set preview range	You can set the preview range by dragging the preview slider at the top. Once set, the entire playback will only be in the preview area. Shortcut key B: You can quickly move the starting position of the preview area to the current time code position. Shortcut key N: You can quickly move the end position of the preview area to the current time code position.
8. Zoom time code line	Use the [slider] at the bottom left of the track to zoom in and out the time code line. Shortcut key 1: Reduce the time code line. Shortcut key 2: Enlarge the time code line.

4.3、Keyframe

Keyframe curve definition

After adding a Keyframe, click the curve interface button to open the curve. The curve changes, according to the rule of Bezier curve.

Overall operation
Open / close curve interface	Select the trick and click the curve button on the left side of the track to open the Keyframe curve page, as shown in the red box above the position marked.
Curve display	After opening, the track page position on the right becomes a curve display. The ordinate is the curve value, the abscissa is the time, and each parameter in the special effect has an independent line performance. For example, position, green represents Y value, red represents X value. Perform the following operations to accurately adjust the curve area: A: Ctrl + scroll wheel, zoom curve interface; B: Scroll the wheel to adjust the curve interface to view more values.
Add a Keyframe	To add a Keyframe to the curve, the operation is as follows: Ctrl + left mouse button, click on a certain position of the curve to Add the Keyframe (only when the mouse is on the curve).
Click keyframe	Click a Keyframe, and handles will appear on the left and right of the Keyframe. Drag the handle to adjust the Keyframe curve. There is only one handle on both sides of the Keyframe, and the middle Keyframe has two handles.
Handle operation	Drag the handle to adjust the curve. When there are two handles, the two handles change the curve on both sides in linkage.
Single handle operation	Operate a handle on the left and right of the Keyframe to change the curve on one side. The specific operation is as follows: hold down Shift + drag the handle.
Delete Keyframe	In the current curve mode, select the Keyframe and click the Delete button to delete it.

5、Introduction to the preview window

Definition

Preview window: The window for viewing special effects. Click play to preview in real time. The created special effects can also be used for other operations on the track material.

Coordinate system definition

The Meishe coordinate system takes the picture as the center point, as the (0,0) point. During the production process, the frame size is 720P, that is, in the case of 16:9, the screen resolution is 1280x720P. So the actual upper left corner coordinates are (-640,360), which is different from AE. When positioning the position, you must first convert it before using it.

Overall operation

9. Start to enter the caption production module

After opening the tool, a guide page pops up, click [Create New]-[Caption]-[Create] to enter the Caption creation page.

10、Caption track

After entering the caption production page, the structure of the caption production page and the filter production page are similar, with the following differences:

Add caption track: The caption track is the track for caption text modification and movement. It cannot be deleted. Only one caption track is allowed.

Cannot add [input source] track: The output of caption production is a caption package, and it is not allowed to add input source track.

The preview video can be replaced (the video will not be brought into the caption package).

Caption properties panel: The caption track can set the trick of the original track, and you can also set the own properties of the caption, which will be described in detail below.

11、Caption properties panel

Click on the caption track, the text attribute panel appears on the right, as follows:

Operating
Text	Enter the text and check the effect in the caption package. It will not be written into the caption package. The final applied caption content is still input by the user.
Default font	Add a font and the font will be written into the caption package. When applying the caption in the SDK, if the same font is installed on the device, the font effect will be used.
	The text is displayed in italics.
	The text is bold, the default is not bold.
	The thickness of the text, the default is 100, and the maximum is 900. Note： Thickness and bolding are mutually exclusive. After setting the thickness, the system will match and find a suitable one. In extreme cases, after some fonts are set to the thickest, if the font has no relevant thickness, it will be matched to other fonts. Use this function with caution.
Font size	Set the size of the text, but the definition is different for normal caption and border caption Normal caption: set the size of the current text Border caption: In the case of border caption, the size of the border caption will be automatically scaled according to the amount of text, so the text size is set to the maximum size of the text in the case of border caption
Text color	Used to set the color of the text, providing a variety of methods such as color wheel and input value for setting
Text alignment	Used to set the alignment of the text, divided into left alignment, center alignment, and right alignment. When the input text is multi-line, you can see the related effects
Word spacing	Used to adjust the space between text
Line spacing	Used to adjust the text spacing between each line when multi-line text
Draw shadow	Function on: After clicking on, you can determine whether the text is shaded
	Color: Set the shadow color.
	Feather: Set the degree of shadow feathering, which can be used as shadow blur.
	Offset: used to set the x, y offset of the shadow and the text itself, the unit is pixel
Draw stroke	Function on: After clicking on, you can add a stroke effect to the text
	Color: used to formulate the color of the stroke
	Width: used to specify the width of the stroke
Background color	Function on: After clicking on, you can add a background color to the text, the default background color is white
	Color: You can set the color value of the background color
	Ground color rounded corners: refers to the rounded corners of the ground color
Lateral extension	It is used to set the content extension method after text input. There are three cases of extension to the right, extension to both sides and extension to the left, as follows Extend to the right: After entering text, the leftmost position of the entire text remains unchanged, and the text will increase to the right Extend to the left: After entering the text, the rightmost position of the entire text remains unchanged, and the text will increase to the left Extend on both sides: After entering text, the position of the center of the text remains unchanged, and the text will increase evenly on both sides Note 1: The extension method is best to be specified before adjusting the position of the subtitle screen, because changing this value will change some offset of the text Note 2: The change of the extension method will also change the rotation anchor point of the text, and the change of the horizontal extension method will affect the anchor point X position of the entire text box
Longitudinal extension	It is used to set the content extension method after multi-line text input. There are three cases of extending downward, extending on both sides and extending upward, as follows Extend downwards: After entering multiple lines, the position of the first line remains unchanged, and the text extends downwards Extend upward: After entering multiple lines, the position of the last line remains unchanged, and the text extends upwards Extend on both sides: After multiple lines are entered, the center of the text position remains unchanged, and the text extends to the upper and lower sides Note 1: The extension method is best to be specified before adjusting the position of the subtitle screen, because changing this value will change some offset of the text Note 2: The change of the extension method will also change the rotation anchor point of the text. The change of the vertical extension method will affect the Y position of the anchor point of the entire text frame.
Flower word edit	Flower word editing is a special mode in the entire caption. It allows the text to be assembled from multiple effects to design better artistic effects. Here are a few points to pay attention to 1. Flower word can be used as a part of Captionstyle or exported as an independent flower word package 2. Once the flower word is used, the original caption color and stroke function will be disabled, please pay attention There will be a special chapter on flower word to introduce flower word editing
Border caption	Border caption are another form of caption. In the case of ordinary caption, the text will increase in length as the input increases. However, if border caption are used, the caption will be controlled within a fixed border. After increasing the number of texts, it will automatically shrink and wrap the caption. Later we will have a detailed chapter on border caption
Stretch caption	Stretchable caption are another way to allow caption to cooperate with other material tracks to achieve the background stretching effect. When it is not turned on, no matter how much caption are input, other tracks are fixed, and when the stretch is turned on, other The track can be turned into a background stretching element to realize the stretching change that affects the background as the number of text changes, which will be introduced in specific chapters later

Border size	Length and height, default [400,200], can be set, pixel is px.
Control box parameters	The control box is a unique concept of Meishe caption. The caption use the drag area, such as the blue box in the figure below, to set the four corner parameters, and use the relevant parameters when dragging. The control frame is orange when it is dragged. The base image and text are wrapped around the frame for a better experience.

14、Stretchable background caption

Special text matching with base image. After inputting different amount of text, the background is adjusted according to the actual length of text, for example:

14.1、Stretchable caption

The text length is changed, the base image is automatically stretched, and the caption track and related tracks are set.

Caption function

Function on

In the caption special effects panel, [Enable stretchable caption] option.

Related tracks

Track settings

After the track is imported, the default is the normal state. Select [Stretch Element] from the drop-down menu, the track becomes a stretch element and the original size becomes invalid.

Element size

After the track attribute is the stretched element, click the [Set] button, and a pop-up window will appear for setting.

14.2、Introduction to Stretching Elements

After checking as stretchable subtitles, set the stretch elements for other tracks. The specific steps are as follows:

Drag the material to the track.

The property of the material is set to [stretch element].

Click the [Set] button to pop up the setting interface

The stretching element binds the four sides of the material on the track, the four sides of the text, and the two center lines. The material changes with the text and the size of the material changes. This is a deformation process.

14.2.1、Baseline

As shown in the figure above, in the subtitles, there are six baselines: CL, CR, CT, CB, CVC, and CHC, which represent:

cl=left, cr=right, ct=top, cb=bottom, cvc=vertical center, chc=horizontal center.

Add stretch elements to the text, and bind the four sides of the material to 6 datums. Examples are as follows:

When the text changes horizontally and vertically in the middle, the four sides of the element are left=cl, right=cr, top=ct, and bottom=cb.

14.2.2、Element change

A、Normal element size:

B、Stretching elements:

C、After adding more text:

Become a background stretching element, providing a quick setting method for sudoku. When setting, click on a position in the sudoku to see the changes.

14.2.3、Lattice interpretation

lattice	Sample	Explanation
Upper left		The upper left position of the text, the width and height will not be stretched.
Upper middle		The upper position of the text, the width stretches with the text, and the height does not change.
Upper right		At the top right of the text, the width and height will not be stretched.
Middle left		The width of the text remains at the middle left position, and the height is stretched with the text.
middle		In the middle of the text, the width and height stretch with the text.
Middle right		The width of the text in the middle right position remains unchanged, and the height is stretched with the text.
Lower left		The width and height of the text at the lower left position will not be stretched.
Middle and lower		The lower and middle position of the text, the width stretches with the text, and the height does not change.
Lower right		The width and height of the text at the lower right position will not be stretched.

The above shortcut operations are more convenient to determine the attributes of the stretched element. You can also set the boundary to determine the stretch of the element.

14.2.4、Other effects

You can offset based on each boundary setting, and make the following effects:

A. No offset:

B. After offset:

C. Manually set the offset of the boundary, which is the horizontal and vertical center, and set the effect based on the center, such as the colorful line in the figure below:

The stretching element and the text movement together provide a function. The transformation attribute of the stretching element is the same as that of the caption, and the same caption effect can be achieved, and the defa

ult is synchronized state.

16、Explanation of making frame and coordinates

For the particularity of different scenes, Meishe special effects can be produced in a special effects package for multi-frame special effects. For example, some foreground animations, borders and other effects, through designing different frames, in order to achieve the most perfect effect in use. There are various editing frames of the video itself. In the process of design and production, you can make typical frames. Inside the Meishe SDK, there is a compatible matching mechanism to ensure actual shooting and editing in different frame situations, allowing special effects to adapt.

Listed below are which ones need to be produced in multiple formats and which ones can be produced in one format

Multi-frame production: frame filter, foreground animation type filter, split screen filter, album

No need to multi-frame: color filter, special effect animation filter (depending on the specific form, there may be differences)

Frame coordinates of Meishe:

The Meishe coordinate system uses the center of the frame as the (0,0) point. For example: 1280x720 frame distance, the upper left corner of the screen is (-640, 360), the lower right corner of the screen is (640, -360), the coordinate origin of the material is the center point of the current material

18、knowledge base

Knowledge base
Serial number	Description
1	CAF: A set of sequence frame animation format defined by the Meishe SDK. The sequence frame animation exported by PS and other tools can be made into a CAF file and used in the beauty effect. This manual contains, CAF production help
2	Frame adaptation: In video production, there are often multiple frames. After putting in a special effects package, you will find the frame closest to it and use it. For example, when making a 16:9 video and applying special effects, if there is a 16:9 frame in the package, this frame design will be applied. However, the frames in the package often cannot cover all video frames. The SDK will automatically find the closest frame and adapt it. For example, there is an 18:9 frame design in the bag. When making a 17.5:9 video, the 18:9 frame will be used for adaptation so that the effect is appropriate No frame adaptation is required. Case: Some filters can be compatible with all productions even if you only write one frame. For example, color filters and some special effects filters will not be affected by the frame. When making effects, you only need to make a default 16:9 ratio.
3	Introduction to Alpha channel diagram, there are special documents, please refer to the detailed document [Introduction to Alpha Channel]
4	LUT: Meishe supports the use of 3D LUT files for color matching. The file that supports import is mslut. Compared with the direct PNG LUT, MSLUT is a unique format of Meishe. Significantly reduce the size of the LUT file in order to reduce the special effects package. MSLUT is also a conversion tool we provide
5	Normalized coordinates: The screen coordinates are normalized, and the center point of the screen is (0,0). The range of X is -1 to 1, and the range of Y is -1 to 1. Under normalized coordinates, the coordinates of the four points are (-1,1), (1,1), (-1,-1), (1,-1), respectively, for the upper left, upper right, lower left, and lower right.
