So this is the script I usually use as .bat where I input youtube video URL or playlist URL (%input%)

set /p input="Input URL: "
youtube-dl -ci --write-thumbnail --sub-format ass/srt/best --write-auto-sub -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/mp4 "/Videos/%%(uploader)s - %%(title)s (%%(id)s).%%(ext)s" %input%

It depends on the video, some videos start downloading, but with some the cmd window just closes.

You're missing -o before "/Videos/%(uploader)s - %(title)s (%(id)s).%(ext)s"

Thanks, it works now. I guess this is a something new, because it was working all the time until I updated.

What's your original version? -o is there for more than 1 year.

[rudolphos]

I guess I might have somehow accidentally removed the -o.
Because I checked the other .bat script which I have (downloads batch of videos, and it has --output).

youtube-dl -ci --write-thumbnail --sub-format ass/srt/best --write-auto-sub -f bestvideo+bestaudio/best --output "%%(uploader)s - %%(title)s (%%(id)s).%%(ext)s" --batch-file="ytdllinks.txt"

Or maybe it wasn't there at all and just started showing errors after the latest few versions of youtube-dl.
Anyway, it works now, thanks for the help.
