A very easy way to compress a raw video data.
What you need is 1. Video file (example .AVI) 2. Virtualdub (http://www.virtualdub.org)
How to proceed: Download stable version of virtualdub. Run the program virtualdub.exe and open your raw video file.
Now go to>Video and Select>Fast Recompress then go to compression and select the codec
if you are using xvid go to configure and select the appropriate setting. Drag the slider to get the right quality and filesize
Thanks..
