This would have been so useful when I was on a restricted internet connection a few years ago and trying to download some small archery clips for a compilation. No need to download a full 30 minute match!

Re: Show HN: Download videos, but only the parts you want
#12I got HTTP 500 when trying to download anything using the demo site. Not sure if the server is overloaded, or a bug (would non-Latin characters in title affect anything?)
The video I tried is https://www.youtube.com/watch?v=5-X_2VXpEds and I just set a start and stop time.

#13Pretty cool! I'm curious as to why this is offered as a cloud machine and not something that runs locally. Wouldn't the encoding performance on a free or cheap cloud instance be poor? I create a lot of video compilations using twitch and youtube videos as source. My internet is 5Mbps down, 3Mbps up, so it can take hours to download long video streams and extract just the parts I want. Because of my network limitation…
Wow, that's magic! (It depends on youtube-dl -g producing a video URL that ffmpeg understands, which unfortunately is not always the case.) Related: https://github.com/ytdl-org/youtube-dl/blob/master/README.md...
Actually, the site seems to be based on doing basically the same by forking yt-dlp -J with one API request and then ffmpeg with another. The ffmpeg options: https://github.com/davidguttman/video-download-tool/blob/mai...

That's why he uses `-f best`, which in 99% cases will give the best single-file output from YouTube that ffmpeg definitely can understand (the exception being live streaming or VOD of a just finished live streaming, which may not have a non-DASH variant.)
The caveat is this will only give you up to 720p video, since higher quality have separate audio and video (likely in DASH format), which ffmpeg can understand, but you need to modify the command accordingly. (The default for youtube-dl is `-f bestvideo+bestaudio`; with `-g` it gives you exactly that: two urls for audio and video respectively).

#15Sry but is there any online tools to do this? We all know there are a lot of online sites to download Youtube videos, but seems no such feature?
From personal experience.
There are a few out there, some have been shutdown for some reason, some seem to be not working and ones which promise think kind of feature are paid. So I needed a 30seconds clip from a 40mins video and not something that I need that frequently that I want pay a monthly subscription for. I ended up using youtube-dl and with a lot of trial and error of various custom commands to finally get what I wanted.

I think you just answered your own question. ;)

If I'm understanding correctly your snippet you're downloading the whole video anyway, no?

I assume ffmpeg is seeking ahead with the http Range header

clipconverter.cc is the only one that worked with long videos for me
