Get Best Video Quality Size

[parsasaei]

How can I get the size of best video quality with mp4 format ?
Is there anyway?

youtube-dl -F URL | grep mp4 should do it, if you are using linux. Otherwise just youtube-dl -F URL and search the list for mp4. By the way checking the man with youtube-dl --help could help. Please, close this issue by yourself if my reply answers your question.

• List formats with -F
• Then pick format with -f <format-id>

--format "(bestvideo+bestaudio)[ext=mp4]/best[ext=mp4]" tries best video quality with best audio, making sure it's MP4 but if that fails it takes the best existing MP4 combination instead.

If I were you I'd use --format "bestvideo+bestaudio/best instead, so it gets the best video with best audio, using FFmpeg or avconv to combine them, otherwise taking the best existing combination. Once the result is downloaded, use FFmpeg or avconv to convert to MP4. That's a story for another time and without research I can't tell what command to use.
