Creating SWF files from MP4

Sorry, but i need to correct this. There won't be quality loss if you convert lossless->lossless (wav->flac) or lossy->lossless (mp3->flac, but it doesn't make sense to do that).

I was explaining about the video, not about the audio bitrate....
Audio with up to 1500 kbit/s? wow~

by theory it is the same, lossless video is possible too, it just would take insanely much space (height*width*bitdepth*framerate*lenght/8/1024/1024 MB)

for a 5 sec 720p video it'd be 527 MB
