Special effects production case
Split screen filter production, the picture below is the final result.
1、Creative ideas
Let the input screen become a three-split screen, each screen size occupies one-third of the screen.
Use three analog input source tracks, and alpha patten function to achieve.
This case is realized in 16:9 format, and the others are the same.
2、Production process
2.1、Insert a clear video as the input source
Add an alpha channel image to this track, import a 16:9 image, and add a brightness channel to display the following effect.
The alpha channel map is a unique concept of Meishe, and a channel graph can be added to each track. This figure determines the mask area of the screen, and the display area can be dynamically changed. Refer to the introduction of alpha channel for details.
2.2、Track related settings
Set the position of the track screen and display it at the top of the screen. Since it is a three-split screen, the Y value at the top is set to 240, and the loop option of the track is set to loop, and this track always appears.
2.3、Other track production
Follow the same operation to make the other two tracks. The Y values of the two track positions are 0 and -240 respectively. At the same time, the track loop option is set to loop, and the effect is as shown below.
2.4、Filter addition
Add filters for each track to further make rich effects. As shown in the figure below, the videofx filter package is finally output.
