See my DASH-IF presentation from October, 2014:

1. encode multiple bitrates with keyframe alignment:
   ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
     -g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4

   My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
   size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.

Video stabilization using VidStab and FFMPEG

Examples here use the default settings, see the VidStab readme on GitHub for more advanced instructions.

Here's an example video I made

Install ffmpeg with the vidstab plugin from homebrew

brew install ffmpeg --with-libvidstab
