View Full Version : Quantization/macroblocking analyzer for encoded files?

I've been searching for a while so I thought I'd ask: is there a tool to detect and preferably graph quantization/macroblocking levels of an encoded file?

I encoded a flash video that is limited to a certain bitrate and there is macroblocking in a few parts because of high motion. If I could see a graph of the hardest hit areas, perhaps I could design an Avisynth script to filter those areas more heavily, maybe even duplicating frames.

Any ideas?

Most of the tools I know are MPEG-2/MPEG-4/H.264/AVC only.

ffmpeg can print macroblock quantizers for any format it can decode.
