I want to play with CVD, so I need infos!

[SatStorm]

Well, I tested VCD (awful), XVCD (good for movies and some cartoons, suck for video clips)and SVCD (I can't make the picture stable!!!! It flick all the time)

What left for me now? CVD! You know, that svcd format, with the half dvd picture resolution, etc....
I need all the related Info I can found!
Tech info, resolution, bitrate, etc
Also, compatibility and personal experience!

Link me to anything
I also like a ready tmpegenc CVD template, for start testing!
Thanks!

Chao-Ji Video Disc was before SVCD. There was a "fight" for International Standards between the 2. SVCD won.

All SVCD player's are able to play CVD.

It is exactly the same besides the resolution. SVCD is 480x480, CVD is 352x480.

Thanks for your reply!
I know that the resolution is 352x480, but what about the bitrate?
You see, if you got 352x480 and the same bitrate with SVCD, you get more smooth motion, with only a bit less picture quality. Almost not noticable!
If you have lower bitrate, you got smaller files. That means you get more on one cd!

So, the bitrate is the same or not?

You see, the problem with SVCD is that 35 min ain't enough for nothing. You need 3 CD for a movie, and you can't get 45 min episodes of your favorite TV series on one CD.
If the Chao-Ji Video Disc with the picture resolution 352x480 has lower bitrate than SVCD, then you could get about 45-50 minutes on a cd, and if you tweak a bit the audio (let say 44100/192/joint stereo) then you could get even more, without leaving the standards!
That is like sefys SxVCD I think, but I like to try something more standard, with better quality.

The bitrate for both CVD and SVCD have the same max. You can put what ever lower bitrate you want. Neither spec has a set standard constant bit rate, only a max. You could lower the rate to 1000kbit/s if you wanted to.

I fit about 50 minutes (or more) per disc using a video bitrate that produces an actual computed max of 2500kbit/s with an actual avg of 1900kbits/s, and audio @ 128.

Check out Fit CD in the tools section. It's rate calculation is damn near perfect. Then get to know your encoder. Every encoder over shoots your specified bit rate, some more than others. For those numbers above, I use CCE Light with a CBR of 1800.

One thing about CVD and SVCD, CVD is 280 lines of resolution, SVCD is 350. There is a quality difference between the two. To compare, VCD has 240 lines of resolution. The main reasons I make CVD's is the speed factor, and with CCE you only need to check 1/2 horizontal resolution and your done.
