Hi, I just wanted to thank you for helping me with my previous posts at "#16861", "#16862", and "#16863", by telling me I could use "best[ext=mp4][height<=]", but it seems the posts were locked so I couldn't comment on them.

Is there a way to get youtube-dl to save an 854x468 (480p) video with audio as an mp4 instead of an mkv file? Thanks.

I've already answered that: select formats with compatible ext and merge with +.

If I download the 480p video and audio streams separately for this video "https://www.youtube.com/watch?v=Zi_XLOBDo_Y" with youtube-dl, I can combine them together easily with ffmpeg using "ffmpeg -i audio.aac -i video.mp4 -c:v copy -c:a copy -preset superfast output.mp4", but is there a way to get youtube-dl to download that video and combine the files automatically? Thanks.

It seems you can use "--format 140+135" for youtube videos to download and convert a 640x480 video with m4a as mp4, but is there any way for youtube-dl to automatically find the 480p video and audio streams without having to specify the formats? Thanks.
