what is xvid?

[sumeshkri]

kindly explain what is meant by xvid. nowadays frequently heard this term. idont know much about it. i have some mpeg1 files. i want to make a dvd disk with these files. i normally coinvert this files with tda and burn as dvd video. But somewhere i have read that this new format xvid is more compressed and a disk can hold more video than a dvd video disk.plz suggest me the software i need for making a xvid file. and also tell me what is the difference between a dvd video and a xvid.

DVDs use MPEG 2 encoding. Xvid is an open source MPEG 4 part 2 implementation (also known as ASP, or Advanced Simple Profile) similar to Divx, Nero Recode (in ASP mode), etc. Xvid files will not play on regular DVD players. You need a player that supports Divx/Xvid/MPEG4ASP.

dixv for cheapskates?

[guns1inger]

Xvid (and mpeg-4 part2 in general) can achieve approximately the same quality as Mpeg-2 at around half to oner third the bitrate, and therefore size. I say approximately because I believe that some of the techniques used for compression do produce an arguably lower image quality.

If you want a fairly simple way of converting DVDs to Xvid, look at AutoGK or avi.NET. If you are happy to get your hands dirty, look at Virtualdub or AVI Demux, where you have to set the compression parameters yourself.

thanks for the comments.
but what about the size of the video the a xvid disk can hold? xvid files are burned in vcd disks or dvd disks?dvds can be converted to xvid through auto gk. right? then what about the mpeg1 files plz? can i convert the mpeg1 files directly to xvid? if i do that what benefit i am going to get? presently i convert the mpeg1 files to dvd video.

xvid is usually sized to fit on a cd. mpeg1 is an already over compressed format that will not benefit from re-encoding to xvid. not enough kbps left to compress any further.

but what about the size of the video the a xvid disk can hold?

It depends on the bitrate you use (audio and video). I typically fit 3 or 4 movies on a single layer DVD. But I use higher quality (bigger files) than most you might find online. If your movies are 700 MB each you can fit 6 on a DVD.

xvid files are burned in vcd disks or dvd disks?

You can burn them onto CD or DVD (ISO data or UDF format), copy them to USB thumb drives, external USB hard drives, etc. They're just data files. Some older players could only play them off CD but most modern players will play off DVD. Players with USB ports can usually play them off USB drives.

dvds can be converted to xvid through auto gk. right?

Yes.

then what about the mpeg1 files plz? can i convert the mpeg1 files directly to xvid? if i do that what benefit i am going to get? presently i convert the mpeg1 files to dvd video.

It depends on the source file. MPEG1 is often at VCD frame size and bitrates. Converting to XVID AVI may not get you much more compression without further reducing image quality. The good news is that most players that can play Divx/Xvid AVI files can also play MPG files.

Great definition guys....

I really like Xvid; I get far superior results and picture quality than with divx when burning to a DVD and playing on my Samsung 40"LCD. Maybe I am doing something wrong with Divx, but I have tried several programs and techniques.

I find very little difference between Xvid and Divx at comparable settings. Xvid may be a tiny bit better.
