Using VirtualDub to Compress AVI File

Avi containers

AVI data files are containers for both picture and audio tracks. These two paths are interleaved, which intends that both paths are broken up into littler pieces that are then placed one after another: First a spot of video, then the corresponding spot of audio, then a spot of picture again and so on. If the paths were not interleaved, and the audio path was just placed after the picture track, then the clip the difficult thrust would have got to pass searching between the two paths would be considerably greater, which would be a job for the playback.

Compressing AVI containers

For compressing an AVI file, we will utilize a programme called VirtualDub (which you can acquire by clicking on the nexus at the underside of this article). Open VirtualDub, chink compaction from the picture menu. Choose DivX from the compaction window. Chink on configure and choice single base on balls as this is the easiest manner to compress.

Audio compaction and interleaving

In AVI files, the audio path is usually handled by an mp3 codec but you can take another codec in the Audio bill of fare if you wish. In the audio bill of fare you can also put the interleaving configuration. By default, VirtualDub interleaves the audio path every frame. You can change this, but most of the clip there is no ground to make so.

There are two scenes for compressing the audio track. Actually, only one of these scenes will compress, as choosing direct watercourse transcript will only interleave the audio path with the picture track. If you are happy with your audio path as it is, simply choose direct watercourse copy. If you desire to compress the audio path as well as interleave it, choice "full processing mode" and then take which codec you desire to use.

Compress your file

Now simply chink on save as AVI in the data data file menu. Sit back and allow VirtualDub make the work.
