1. Description
This article is aimed at some friends who are not professional users of "Visionary" video processing software, or even novice Xiaobai.
2. Problem description
There is such a video that needs to be edited, called "video to be processed.mp4", its file size is originally 186MB, and its duration is 00:11:59. The size of the exported video.mp4" is 862MB, and the duration is 00:08:54.
By comparison, we can find that the file size of a short video is 4~5 times larger than that of a long video. So what is the reason? What caused it?
3. Problem analysis
What is the specific cause of the problem? Let's look at the two pictures first:
compare them, and then we can understand the reason, and draw a conclusion:
due to the large difference in video data format (including frame width and height, etc.), the large difference in video file size is caused.
4. Problem solving
Since there is a problem with the format when exporting the video, let’s just set the format parameters we need. How to do it?
(1) Select "MPEG-4" and click "+" when exporting video using "Visionary"
(2) At this time, the "New Configuration File Options" dialog box will pop up. At this time, you only need to input parameters in "General" and "Compression", and you can refer to the parameters of the original video, that is, "Video to be processed.mp4", so that the exported video format and quality are not much different
. , click "Start" and you're done
5. Effect
The exported video has a size of 127MB and a duration of 00:08:54 (the original video is 186MB and a duration of 00:11:59), and the export is successful!
6. Summary
In the same way, you can also set different parameters to meet your requirements for video file size and resolution according to the same operation steps according to your needs.
