It may be faster to just download the whole video and chop up w/ ffmpeg. This method downloads and transcodes pretty slow. Yt-dlp.exe -download-sections "*1:22:22-inf" -force-keyframes-at-cutsĭownload a section titled "03. If you need exact start / stop times (albeit slower): It will only download the section specified (to the nearest keyframe). It will ONLY download the section of video you specify, good for low bandwidth or long videos! Yt-dlp, the spiritual successor to youtube-dl, supports this w/ ffmpeg installed. #Arguments: URL, Time stamp -5 seconds, length of clip, video file name I've moved from youtube-dl to yt-dlp for reasons that aren't super important for this post, but you can replace yt-dlp with youtube-dl if you want to continue using it.
# The first URLįfmpeg -ss 42:30 -i "$video_url" -ss 42:30 -i "$audio_url" -map 0:v -map 1:a -ss 30 -t 7:10 -c:v libx264 -c:a aac gog-vs-triv.mkvĬredit to Jakub Vrána for the -youtube-skip-dash-manifest solution.ĮDIT: I do this so often I've created a script that I will include here. I'll then use map to map the video 0:v and audio 1:a (0 means first input, which is the video and 1 means the second input, which is the audio) and then choose my encoding options.
I wanted to cut from 43:00 to 50:10 so I'm going to do -ss 42:30 (giving me a few seconds to catch a good keyframe) on both inputs and then do a -ss 30 after the inputs to start at 43:00. Video youtube-dl -youtube-skip-dash-manifest -g Here's a real example using one of my youtube videos. I also recommend doing it about 30 seconds earlier and then using another -ss 30 to avoid losing any key frames. You'll need to use the -ss option for each stream. Use youtube-dl -youtube-skip-dash-manifest -g "URL" to get the video and audio streams.
