how to compare two video codecs

[rpjanaka]

hi all

i want to get a performance comparison for two codec.

i got some clear idea about this task form "http://people.csail.mit.edu/tbuehler/video/codecs/index.html " .

in addition to that i want to know

-how can i do this comparison practically (the best way to do this).
-want to check parameters like compression quality, video quality, performance with video streaming etc.

-are there any better tools developed for this purpose.


I want to get an idea about how to do this comparison
please can you help me for this .

Use MSU Tool.
But it may not be contained compression quaility comparison.

For quality, encode one input video to two output videos, one using each codec, using the same ratecontrol method (2-pass target bitrate) to the same bitrate. Then compare the SSIM at that bitrate.

Encoding speed is directly related to quality: what matters is what quality one gets at different encoding speeds, or what speed one gets at different quality levels. This can only really be tested well with considerable knowledge of both codecs: that is, knowing that if you want to get speed X, the best settings to use are Y.
