| 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. |

This should be one of the core features of Git, but for some reason it's impossible to figure out how to search for a string in your commit history and see the diffs that that string is in. Here's the best I've come up with:
To find which commits and which files a string was added or removed in:
git log -S'search string' --oneline --name-status
To see the diff of that
