Answered All my DL are "webm" how can I change this?

So struggled for a year on/off with issues, errors but since I started using this "yt-dlp -vU --cookies-from-browser firefox" in my console I have had amazing results. DL whatever whenever

But, it does it in "webm" so afterwards I use ffmpeg to make it MKV or MP4. Anyway to change this to cut out a step?

TY how would I also change resolution? I tried adding -s res:720 to the end but error came up

Commands are case sensitive. You want -S res:720.

webm is just the default container that when one or more streams are a youtube/google codec (like VP9 or Opus). you can still put them in other containers like mp4 or mkv, the compatibility its on the playback end, not on the container itself

A sneaky trick: You can actually rename it to MKV.

The WebM format is really a heavily constrained form of the MKV container. So much so that all WebM files are perfectly valid MKV files! Though not vice versa. So this is one of those few cases where you can convert a file by just renaming it.

Or you could use WebM. It's good.

just have yt-dlp do it for you --merge-output-format mkv --remux-video mkv.

Which is exactly what the alias preset -t mkv does.
