Okay, so I'm struggling to create an anamorphic MP4 file that works in QuickTime, VLC (and other ffmpeg-based players), and iPods and isn't corrupt/broken in one way or another. Optimally I'd like to find a process that only involved OS X-based tools, but if I have to use Windows tools that's acceptable. I checked in the FAQ but it seems to be outdated, and Googling is only marginally helpful at this point.
My current workflow is: make .mov file with the x264encoder component via a Compressor preset (with a gamma adjustment, since x264encoder darkens ProRes source video noticeably) and AAC audio. After this, I'm stumped. Exporting to MP4 using QuickTime Pro (using video and audio pass-through) seems to preserve the aspect ratio information somewhere as the proper display aspect ratio is still listed in the info pane (on the Mac, not on the PC), but it doesn't actually stretch the video.
So I've tried MKVtools on OS X, but that seems to only set the stream-level PAR, which QuickTime doesn't use. I've also tried MP4box on Windows, via YAMB, but again that's only stream-level PAR. The usual suggestion I find from Googling is "use MP4muxer" (a Windows utility). That does make MP4 files that display properly in QuickTime, but showing the movie info reveals a totally borked video track name (on the Mac, fine on PC QuickTime) for some reason. I'm wondering if that file is questionable in other ways, so I'm hesitant to use it.
The only thing I've found that delivers consistent results in the anamorphic MP4 department is HandBrake, and unfortunately since my sources are QuickTime files (ProRes) from FCP, I can't use Handbrake to encode them.
Are the MP4muxer files fine, despite their trashed info lines? Is there any good solution for this in OS X?
