Best Video Compression Technique For My Application?

maj1 · 05-05-2008, 06:23 AM

Good morning. I am not too familiar with video compression techniques, so I am having some trouble figuring out which one would be best for my application.

Essentially, 35% to 60% of the video in the different cameras are "still" (such as the outer wall of a building), while the "background" occasionally changes.

In this case, what is the best compression algorithm to use (mpeg2, wavelet, etc), if bandwidth is an issue? Also, what is the best compression overall?

Thanks!

i don't do a lot with video, but you can start with downloading k-lite full codec pack. it will include DivX (with a lot more) codec which is quite good all rounder. you can vary the compression to get better quality picture or smaller file size.

A good video compression program that allows you to use DivX or Xvid compression is Auto Gordian Knot available at http://www.autogk.me.uk/.
I use this after exporting video files from Premiere Elements and allows you to have decent quality video at smaller file sizes (can reduce them by about 60% and still keep quality) - and best of all it's free!
DivX is the commercial (read - you have to pay for it) version of the Xvid codec.

XviD is my choice for minimal size with maximum quality.

Megui is a far superior program for (free) video compression.

A 2 pass encode always provides the best quality to filesize ratio. However, encode times are slower.
The x264 codec provides better results than XVID but is slower to encode.
