Default WinRAR compression ratio

i'm trying to compress an 800 MB video.
the compression ratio is 99%

..so the .rar file is 780-790 MBs. it didn't really help me.
is this unusual or are video compression ratios usually like this?

What format is the video that you're trying to compress?

If it's anything like MPEG2, MPEG4, AVI, XVid, as well as a few others, then dont expect much if any compression because those formats are already highly compressed, such as MP3 music.



I'm going to take a guess here. You downloaded a movie from a torrent, found out later that it was 800MB, you then realize you only have CD's and can't burn an 800MB video to a 700MB CD, so you're trying to compress it?

uhhh..no
actually, i did not download the 'video,' not 'movie,' off the internet..
..and i, in fact, have plenty of DVD's to use..
..and no, i am not trying to compress it to get it onto a CD.

..however the video is certainly in AVI format
thank you for your advice anyhow

If you have a DVD burner then why not burn it to a DVD?
