On Windows, I recommend FootageStudio 4K. It is a commercial converter (not cheap) that supports many professional formats, including ProRes.

Ffmpeg can encode video using ProRes, and runs cross-platform ffmpeg -i input.avi -c:v prores -profile:v 3 -c:a pcm_s16le output.mov will do the trick.

You can try ffmbc - a customized version of FFmpeg. Unfortunately there are no builds for linux or windows at the moment so you have compile it yourself.

h.264 + aac in .mp4. Google up an x264 settings guide. (or use -preset slower). If you're doing something that the MPEG-LA would charge patent royalties for, screw them and use VP8 or VP9, with maybe a fallback to Theora if that helps compat. Old question, but check the quality at the start of the video if using x264. If it's not good, use 2-pass. I ...

Lossless requires such high bitrates that I have more trouble playing back lossless video than 5Mib/s lossy h.264, on my C2Duo (first gen) E6600, 2.4GHz. lossy 5Mib/s 1080p h.264 at 24fps plays perfectly without even having to use mplayer's -lavdopts threads=2 option. (single-threaded software decoding is enough.) My system isn't fast enough to play ...

After reviewing the PDF, I can confirm that you are misreading it. They are looking for a flash animation, not a video. You will not be able to use your After Effects assets at all. You need to remake the ad as a flash animation in Adobe Flash using vector graphics in order to fit within their 50KB limitation.

At 200px by 200px, you are looking at extreme levels of limitation. You may want to consider something like a gif at that point unless you also need audio. Just audio alone for 8 seconds completely blows your 50KB bandwidth budget. 50KB is a mind numbingly small amount of data. At 8kbps, no raster video format will be usable, even at 10fps and 200 by ...
