View Full Version : How to determine bits per pixel

I am using Easy Real Media Producer to transcode avis to rvmb at a lower bitrate for archive. When I used AutoRV10 it would tell me a setting for the bits/pixel/frame, the result would range from .125 to .25 just so you know what setting I am talking about. If the bits per pixel were too low, I would adjust the resolution of the video until I got a decent result.

Can anyone tell me of a program that would let me input avis and mpegs and find the proper resolution for the desireed output filesize by giving me this statistic: bits per pixel; or bits per pixel per frame?


One other question: What is a good program to use to generate .avs avisynth scripts from avis and mpegs for input to other programs aka an avisynth script generator? I have seen a few along the way bundled with other programs but I can never seem to find them. I really enjoy having the freedom to use ffdshow with directshowsource() and set up my filters inside of ffdshow. I have used Swif AVS and AVIScript and they don't have very good directshowsource implementation.

One that was very good and simple was bundled with Real Anime a while back and it had generator in the name, it was very lite and that is what I am looking for. Something to keep me from having to generate each individual script for each file manually.

Aspect (http://aspect.fre3.com) it's quite good for resolution calculation based on bits per pixel.


BTW:
bits_per_pixel = (1000 * video_bitrate) / (frame_rate * h_res * v_res)
