How to download YouTube Videos quickly
I used to use yt5s all the time to rip and remix videos:
now you have to use https://ytdlp.online/
…but it often downloads the functionally useless .webm extension. Like with other bullshit google extensions, you can simply rename from .webm to .mp4 and it may work – but twitter actually rejects it when you try to upload..
I also keep this flag around
yt-dlp -f "bestvideo(ext=mp4)(height<=720)+bestaudio(ext=m4a)/best(ext=mp4)/best" YOUR_URL_HEREthis is bad: youtube-dl -f bestvideo+bestaudio --merge-output-format mp4 https://www.youtube.com/watch\?v\=VcUl0vPJwxo because it downloads the wrong video (https://chatgpt.com/c/68856117-61c8-8331-b493-9027ad956de5) which you then have to re encode ffmpeg -i yourvideo.mp4 -c:v libx265 -c:a aac fixed.mp4
if Youtube allows do this
yt-dlp -f "bv*(vcodec^=avc1)(ext=mp4)+ba(acodec^=mp4a)/b(vcodec^=avc1)(ext=mp4)" \
--merge-output-format mp4 -o "%(title)s.%(ext)s" https://www.youtube.com/watch?v=VcUl0vPJwxo
yt-dlp -f "bv*+ba/b" --recode-video mp4 \
--postprocessor-args "ffmpeg:-c:v hevc_videotoolbox -b:v 8M -pix_fmt yuv420p -tag:v hvc1 -c:a aac -movflags +faststart" \
-o "%(title)s.%(ext)s" https://www.youtube.com/watch?v=VcUl0vPJwxo
yt-dlp --live-from-start -f "bestvideo(ext=mp4)(height<=720)+bestaudio(ext=m4a)/best(ext=mp4)/best" YOUR_URL_HEREwith time limit cutoff
yt-dlp --hls-prefer-ffmpeg --live-from-start \
--downloader ffmpeg \
--downloader-args "ffmpeg:-t 02:00:00" \
-o "%(title)s_%(upload_date)s_live.%(ext)s" \
"https://www.youtube.com/watch?v=qcO6huB0O8Y"If you ever get a .webm you might use
ffmpeg -i textgeneratorvision.webm -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -shortest -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2,fps=30" -c:v libx264 -pix_fmt yuv420p -c:a aac textgeneratorvision.mp4per this guy
and
yt-dlp -f "bestvideo+bestaudio(ext=m4a)/bestvideo+bestaudio/best" -o "%(title)s.%(ext)s" --merge-output-format mp4
