Which format compresses video better?

Question

Video

I wanted to watch the movie, but I was faced with the choice of watching the movie m3u8 and mp4. And my Internet is bad, and I would like to ask which compresses better for viewing

Answer 1

m3u8 and mp4 are not formats.
m3u8 is a set of links for a player that downloads the video fragments listed in it in order. Playlist. Opened and read with notepad.
mp4 is a container into which you can stuff a fairly large number of "formats" - codecs.
Therefore, your question cannot be answered.
