Creating SWF files from MP4

There will always be an quallity-loss, if you confert a file.
And remember: as higher the bitrate as better will the quallity be. But z0r.de has a filesize limit of 2MB. So the bitrate is mostly between 600 and 1500.

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~
