comment How can I use FFmpeg to lower the quality of H264 video but keep it in H264 format?
Constant bitrate is the worst (in terms of quality vs. size) of all rate control modes in x264 and should be avoided. Use -crf to set a constant quality mode instead.

comment How can I move a floating text or image with the video?
@Y.G.J As AJ said. Plus, you will have to do the 3D animation separately – this has nothing to do with the motion tracking itself.

FFmpeg won't put JPEG2000 in MXF, even with the codec enabled.

comment Capture Date For Video
Oh, you got caught in that Mac App Store trap some developers think they have to set up. On the MediaInfo download page, just look a few pixels down to where it says "free GUI".

Of course it's free. It even says so on the homepage and I've been using it for years. Where are you prompted to pay?

comment How do I specify baseline H264 profile using FFmbc?
You're right. Back when I wrote this FFmpeg was about to change the whole thing and everything was a little confusing. +1 to you.
