Youtube video quality question:
https://www.youtube.com/watch?v=iecTvnLmiak
I'm trying to download the subbed Crayon Shin-chan movies from Muse Asia and then upload them to nyaa for archival purposes. If I want to get the highest quality video/audio, which option do I take here?

I would get 251 and 136 and then merge them using ffmpeg

Cool.
I tried using the -f 136+251 --merge-output-format mp4 command on yt-dlp but it gave ERROR: Postprocessing: Stream #1:0 -> #0:1 (copy)

So now I do it with ffmpeg with this command I found of google ffmpeg -i video.mp4 -i audio.webm -c:v copy -c:a aac video480p.mp4
Though I wonder if re-encoding the audio to aac is necessary.

My bad, turns out I can just remove the merge to mp4 command and yt-dlp just merges them as mkv just fine.

Make sure to note the URL you got this from and that it's from youtube, which already shits on the quality of the video the moment you upload it.
Find this elsewhere if you can and archive that.

It's fine, the target of the archival is the hardsubs because some Crayon Shin-chan movies have only MTL available.

Well, I didn't know nyaa didn't allow anonymous uploads or registration... don't know what to do now.

You can just do yt-dlp -f bv+ba and it will automatically select the best video and audio quality and merge them into an MKV.
