1. Pr losslessly compresses large videos, the image quality remains unchanged, and the capacity is greatly reduced
When we want to send some special effects videos made with AE to the Internet or WeChat, we often encounter large video files, which are inconvenient to upload, which is very distressing. Here, the author teaches you to use Premiere to compress the video, and it is lossless quality, the picture quality is unchanged, but the video capacity can be greatly reduced.
Import the video file you want to compress in pr, drag it to the time panel, click [File]
at the top of the pr work interface , select [Export], [Media]
in the pop-up drop-down menu, in the opened page, click [Export] Under [Settings],
select [Format], select [H.264],
select [Video]
under [Bit Rate Settings], click the menu box to the right of [Bit Rate Encoding], select [NBR, Once]
in the pop-up Select [CBR]
[Target Bit Rate] in the menu and change it to 4.
At this time, we can see that the file size of the exported video is about 15MB. Click [Export]
2. How to remove the black border in the cropped video?
In fact, it is very simple, search for the crop in the effect bar, pull in the sequence and crop the video; click the source in the upper left corner when exporting, then click the crop icon, display the box and pull the box to adjust the cropping range, and finally export the video.
Use the "anchor point" in the effect control to adjust the position, then search for "crop" in the effect bar and drag it to the sequence, then drag the value in the "crop" tab in the effect control to adapt it to the requirements, and then tick Select "Zoom" to keep the rest.
Of course, this is a relatively indirect method, and the main problem is still resolution.
