Hi, when trying to download these links: "https://www.youtube.com/watch?v=ezopeXwUukQ", "https://www.youtube.com/watch?v=1WjxBLgsQy8", and "https://www.youtube.com/watch?v=0DdPkt2QOKk" using the "-v --ignore-errors --format "best[ext=mp4][height<=720]" -o %(title)s.%(ext)s --cache-dir "C:\Users\Computer User\Music\youtube-dl and libav 11.3 files cache and downloads" --batch-file Files.txt" command, youtube-dl downloads them as 540x360 and 480x320 mp4, or 720x480 mkv files, but other youtube downloaders are able to download and convert those same files from the available streams as 720x480 mp4 files. It seems that issue is that youtube-dl isn't able to download and convert the proper available streams and merge them to create mp4 files, so is there a way to fix that? If other youtube downloaders can do that, then why can't youtube-dl? Thanks.

Hi, is there a way to merge all of these similar service requests: "#20831", "#20832", "#20887", and "#20888" into one service request? You provided me with the "--format "best[ext=mp4][height<=720]" command to use to download and convert files as 720p mp4 a while ago when I wanted help with that, because I didn't know which command to use. Everything was working fine and youtube-dl was able to download videos properly and convert them in that format until recently. Can you please tell me what command to use for youtube-dl to download videos in 720p (in this case, in the available 720x480 resolution), and mux the available streams using ffmpeg into an mp4 file? So far, I've only found out how to get youtube-dl to download the videos in the correct 720x480 available resolution, but it saves them as mkv files, and I want to find out how to get it to use ffmpeg to convert them to mp4 files. I'd really appreciate it, since the faq is very confusting for average computer users. Youtube-dl is a very good program by the way, once people know how to use it. Thank you.
