Hey guys, based on this:
http://webcache.googleusercontent.com/search?q=cache:uP_EPJI98igJ:lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-October/036474.html+ffmpeg+png+compression&cd=1&hl=en&ct=clnk&gl=us&source=www.google.com

it seems there is some way to set the compression level when using pngenc (-vcodec png). I can't seem to figure out how to do it though. I tried -compression_level, but that doesn't seem to be doing what I expect. It has an effect on the result but its always far larger than the source.

My source is 84 frames of uncompressed tiffs which are 222 MB in size altogether. With compression level 0 my mov file is 534 MB, and with level 9 it is 275 MB. In either case it's much larger than the uncompressed frames! Something not right...

Thanks for the help!
