To compress, you have to crack the video file, otherwise it is not called compression. The video file in the original format is surprisingly large.

There are many video compression software. Generally speaking, specialized conversion tools will be more effective. A tool that can rotate everything is even worse.

I don't know what format you want to convert. There's nothing to say!

First of all, you need the decompression principle: rmvb adopts dynamic compression (intelligent mode), automatically adopts high compression for relatively still images in video, and appropriately reduces the compression ratio for moving images to ensure clarity and improve quality. So the relationship between its compression effect and the size of the generated file is the best.

Rmvb not only ensures the compression rate but also gives consideration to the quality, which is why bt videos on the Internet are basically in rmvb format.

There are many compression methods of avi format, but all of them are uniform compression rate (not intelligent), and the compression effect is not as good as rmvb. If you want a better image, the file must be bigger, and the image is almost the same if the file is smaller.

So when your player plays moving pictures, the compression rate will be very low, the sampling rate will be very high, and of course it will be very stuck.

You can't have your cake and eat it. Do you want to change to a better mp5, hehe!
