which is better avi or mpeg in regards to quality size etc
whats better avi or mpeg
- Thread starter badboy2002
- Start date
is that mpg 1 or mpeg 2 as there is a difference between those too in regards to quality and audio !
avi is usually used as an output of divx compression which varies depending on how much compression is used etc etc !
Im sure our resident gurus here in this section can explain more in better detail than i can but i know this basic information from using the different formats and reading articles here

Viper's on the right track here. In many ways, this is like comparing apples and bolts.
MPEG 1 or 2 is a fully defined video spec. It dictates the way the video is compressed and stored. There is some latitude in the audio, but in general MPEGS are a known quantity. There is also leeway under MPEG2 to do heavier or lighter compression. This can result in better or worse quality.
AVI, on the other hand, is simply a container format. This means that it does not dictate anything about the video or audio streams that are contained. Their quality is entirely dependent on the underlying compression that is used. Popular compressions are DIVX & XVID for video.
The point of your question, though, is clear in my mind. What you are probably asking is "which is better: MPEG2 or DIVX/XVID" (if I'm not right in this assumption, respond and say so).
My answer (as usual) is "it depends".
MPEG2 is better since it is universal and the basis of DVD. Author one of these, burn it, plunk it in the player, and it works!
DIVX/XVID is better since it is so compressed. You can fit a full movie on 1 or 2 CDs (not DVDs), or several on one DVD.

Well MP4, I guess is still covered by MPEG and if by AVI you mean one that uses DivX or XviD for video compression and mp3 for audio.
MP4 can also use DivX or XviD for video and mp3 for audio, although I would think it can actually handle vbr mp3's and bframes without any nasty hacks. The actual container for MP4 is based on quicktime.
Also there is a VFW MPEG2 codec, so you can have MPEG2 in an AVI if you want, although from recollection it was I frames only.

my 2 cents
I guess that depends on what you are trying to achieve.
If you want MPEG than you want to use MPEG2 (SVCD,DVD) definately good quality, i use www.dvd2svcd.org with Cinema Craft Encoder (CCE) (you can find cce in one of those peer to peer file sharing program) to encode DVD discs to SVCD and play it on my DVD player.
If you don't plan to use a DVD player than AVI as in DVIX which is MP4 and can give you same or higher quality than SVCD at half the size but you will be able to play it only on your computer and i think something came out for the XBOX.
PS.
SVCD you'll need 2 cd's for a movie as a minimum (enough for me)
DIVX you could fit a movie on one cd.
Cheers
