    What you are describing might be so called "bitstarved chroma" (first google image result will show you what it looks like) It can be fixed by encoding at higher bitrate/lower crf or setting lower chroma qp offset (which will result in more bits allocated for chroma) -x264-params chroma-qp-offset=-1

    After more testing of H264 3D video playback, I've found that the image for left eye is one frame ahead of the right eye (only in player, the video file itself is in sync). It can be fixed by delaying left image by one frame by adding ";tpad=start=1" to the end of the filter. I haven't noticed...

    Yes, the difference is not big, it mostly gets masked by the MJPEG compression, but it's still visible and it's not advisable to re-encode video multiple times, since each encode takes time and decreases quality (even if not by a huge margin).

    Yes, it plays nicely, although only with software decoding, with hardware decoding it stalls after few seconds.

    I want to expand on Tobias' 3D encoding guide. While it provides a good starting point, encoding the video in three steps (downsample, split, merge) is quite wasteful, both in the time it takes and the quality loss. Instead, it is possible to do it all in one go: ffmpeg -i INPUT -filter_complex...
