Bouncing now, but since it's a quicktime plugin.component, it only works through QuickTime, or in Final Cut using QuickTime conversion.
i.e. I can only save as .mov.
..aaaaand, it's 98 MB. ~30 MB larger than the flv. But the quality is slightly better. Yes, the audio is mp3, 128.
Maybe if I could save it as an .mp4? .... but I can't. And I fear taking the .mov I just made and turning it into an mp4 will result in the loss of quality.
God, it really doesn't help that every time I google for x264 I get a million hits for h.264 instead.
And it really doesn't help that there's so many advanced settings.
I'm downloading Avidemux ...
edit: I figured it out. Bouncing in high quality, like, triples the file size, and doesn't even do that much for the quality. Leaving it at medium quality gets me a smaller file, and (astonishingly) better quality than .flv.
Sorry again, Roph.
You can have your BJ back.
