Just curious. It seems that a lot of people prefer encoding their DVDs in this format. Why not just convert them to SVCD?

SVCD isn't MPEG-2.

SVCD is an extension on the VCD MPEG-1 format. It produces higher resolution and the faster pans and action scenes are more *solid* and have less digital artefacts. It plays on most DVD players and pretty much all VCD players (very big in asia).

Divx does not play on a standard dvd player nor does XVid. These two formats can produce MUCH better quality then SVCD's because they are less bounded by the MPEG-1 format that is needed to be played on the DVD and VCD players. Your pc can be updated with codecs so you can get pretty much insanely high res Divx rips from DVD. Higher res and full control over compresion and thus looks better in fast action sequences. Doesn't suffer from *blocking* like SVCD does at fast action sequences.

That is an understatement. A video properly encoded in either Divx or Xvid will blow away a SVCD in quality, hands down.

As I understand it SVCD is MPEG-2. When I make SVCD they are based on a 480 x 480 MPEG-2 file while DVDs are based on a 720 x 480 MPEG-2. MPEG-1, if I'm remembering correctly, doesn't go over about 320 x 320. A good SVCD is close to DVD in quality. The real difference is the advanced compression. With SVCD, a CD will hold about 34 minutes. You can get about the same quality of DIVX and put well over an hour on a CD.

svcd are mpeg-2 according to every encoder/guide i've ever used.

SVCD is indeed mpeg-2. Xvid/Divx uses mpeg-4 which offers better compression then mpeg-2 without much sacrifice of video quality. A high quality SVCD rip will look nearly identical to the same video in a highquality divx/xvid rip. People prefer Xvid/Divx because of smaller filesize, and the ability to keep the original ac3 track from the DVD. People prefer SVCD because it does better rips with lower quality sources (vhs/tvcap/Telesync) and plays in most standalone dvd players.

You sure? I'm not 100% sure myself. But the aspect ratios you put are not even 4:3. They are 1:1! Our tv's are that. Normal tv 4:3 and widescreen 16:9. The MPEG one is 320 x 240 res I'd think. That gives you the proper ratio.

The hour of Dvix on a cd won't play in your dvd player though. Sure you can store it but it won't play on a dvd player and thus you are left with a pc monitor or a projector/plasma if you have one! (wish I did :D)

Hey hdeck that would mean that MPEG 2 was around before DVD players were.......

I thought that SVCD's were out quite a while before DVD's came out.......

So wait a second...if I encoded a dvd into DivX or XVid, and I used the line out of my sound card to a reciever, I would get 5.1 sound?

i could be wrong, but i dont think so.

there may be ways of adding the 5.1 track to the file.

You have to use digital out from your sound card to get Dolby Digital sound from your computer to a reciever. Your divx or xvid file also has to have an AC3 soundtrack.

This is correct. Sometimes I just mux the Ac3 soundtrack with the video to maintain the 5.1 surround audio, if the video filesize is small enough or it is a long movie and I am making it 2 CDs anyway. As long as the Ac3 soundtrack on the DVD was 5.1 you will get the surround audio if you output your soundcard correctly to the reciever.

Wrong.

The hour of Dvix on a cd won't play in your dvd player though.

It will if you use TMPGEnc Plus to encode to SVCD.

My bad on the first quote :(

The 2nd quote isn't true. The hour of DVIX on a cd won't play on a dvd player. If you encode it to SVCD then it will play but then it isn't a DVIX file anymore, its a SVCD now. The end result is what it is. You can encode any file to play on a dvd player.......

from what i've seen, vcd and svcd just suffer from their limited bitrate. mpeg1 can look pretty decent at a hgih bitrate, but on a vcd its stretched so thin you get cr@p, same with mpeg2 on svcd.

playback svcd or vcd on a monitor or a decent res display and u see pixels and macroblox. ick.

divx is ok for compressing to small space if you have to, it has its own set of artifacts.

dvd is the way to go if u can:) hd-dvd, i can't wait:)
