Little PSA for mastodon users
If anyone wants to know what format to upload videos into, that won't take multiple minutes to process (and which will be the format that mastodon re-encodes to anyways), then use the following ffmpeg command;
ffmpeg -i input.mov -c:v libx264 -pix_fmt yuv420p -c:a aac -movflags +faststart output.mp4
Or;
- MP4
- Video Codec h264
- Audio Codec AAC
- Pixel Format
yuv420p
Anything else gets re-encoded, including .mov and .webm, to this.
