Problem with MOV > FLV conversion

[sprinke]

Here is the log. Any hints? I notice that when I try to play or preview the source, it's spotty and gray. Source plays fine in VLC, MPEG Streamclip, and Quicktime. It was encoded using the "Normal" setting of Handbrake.

[Case]

I'm not sure why ffmpeg doesn't like the H.264 video stream. It may have to do with the age of this version of ffmpeg in ffmpegX, as ffmpeg has seen a few revisions since, with improvements in handling of H.264 video.

Alternatives:
- ffmpeg command line (build your own (e.g. through MacPorts) or 'borrow' a compiled version from some recent app that has ffmpeg in its package)
- Convert a copy to .mp4 (lower specs) with Handbrake/QuickTime/MPEG Streamclip/whatever, as H.264/AAC .mp4 is compatible with web Flash players, too. [Recommended]
