Download Video / Music
ID:
— Open the watch pageselect a format to download :3 Muxed is audio+video and Video only needs a separate audio track if you plan to mux!

Muxed formats
Audio-only formats
Video-only formats
No audio!! You may need to mux with an audio track :c
if a download fails try another container (MP4 vs WEBM) or a different quality :D
How2 Combine video-only + audio-only (mux)
U can pick one of these methods!!
FFmpeg — MP4 output
ffmpeg -i video.mp4 -i videoplayback.m4a -c copy -map 0:v:0 -map 1:a:0 output.mp4
when your video is MP4 (H.264) and audio is M4A/AAC use dis!
FFmpeg — WEBM output
ffmpeg -i videoplayback.webm -i audio.webm -c copy -map 0:v:0 -map 1:a:0 output.webm
when both tracks are WEBM (VP9/AV1 + Opus) use dis!
FFmpeg — mixed containers
ffmpeg -i videoplayback.webm -i videoplayback.m4a -c copy -map 0:v:0 -map 1:a:0 output.mkv
If containers differ u can mux to mkv
for best compatibility!
Windows (drag-and-drop)
1) Install FFmpeg (add to PATH) 2) Put video and audio next to each other 3) Open Terminal in that folder and run one of the commands above
