Convert pngs to mp4

This FFmpeg command reads images named frame_[4 char digit].png and converts it to an mp4 using the h264 encoding which Twitter accepts. The bitrate is set to 5M to reduce blocking as much as possible while keeping the size small.

ffmpeg -framerate 10 -i frame_%04d.png -c:v h264_qsv -b:v 5M video.mp4

Convert and scale an existing mp4 to 1080:

ffmpeg -i input.mp4 -c:v h264_qsv -vf: scale=1080:-1 -b:v 5M output.mp4
