FFMPEG

⚠️⚠️⚠️ remember I built a mac shortcut for auto-conversion at the OS contextual menu level

Install from conda:

/opt/miniconda3/bin/conda install ffmpeg

transcode to h264 w/ mp4 container:

/opt/miniconda3/bin/ffmpeg -i input.mp4 -c:v h264_videotoolbox output.mp4

convert webm to mp4

ffmpeg -i input.webm. output.mp4

twitterize

/opt/miniconda3/bin/ffmpeg -i input.mp4 -c:v h264_videotoolbox -vf scale=1920:1200 -r 30 output.mp4

Suggestion by AK: https://webservice.online-convert.com/convert-for-twitter

website videos (seems mp4 doesn't allow play/stop, while mov does – h264 seems appropriate); this seem to lead to some visual quality loss though... ok for teasers; adjust -b:v option to control video quality/size

/opt/miniconda3/bin/ffmpeg -i input.mp4 -c:v h264_videotoolbox -b:v 1000k output.mov

find out metadata about a clip:

ffmpeg -i C:\Test\3FA8D0E6-BD61-D160-98BB41304D63FAE3.mp4 -f null -
