[youtube-dl] ERROR: requested format not available

[DarrenZhaoFR]

Hi, many thanks for sharing this dataset.
I'm getting this same error when try to download videos, after some digging, I think its because the video format 22 is not supported, e.g. when I select a link from csv and check the available formats:

- youtube-dl -F https://www.youtube.com/watch\?v\=XzQ3QgZZ1DM

There are actually no format 22, and by setting format to 18(best) I'm getting 360p videos, which are very blurry.
So which format should I use?

Getting the same errors here

Hi! I think this may be due to modifications made on the YouTube website. Format 18 has a resolution of 360p, which may result in videos with suboptimal visual quality. You can try a format with a resolution no less than 720p, and I believe this will lead to much better download visual quality.

@juxuan27 Is there a recommended format code? Or is there a way to dynamically select the format code for each video?

I changed this line to 'format': '136/247' and it works.
