SVCD
stands for "Super VideoCD". A SVCD is very similiar to a VCD, it has the capacity to hold about 35-60 minutes on 74/80 min CDs of very good quality full-motion video along with up to 2 stereo audio tracks and also 4 selectable subtitles. A SVCD can be played on many standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of a software based decoder / player. It is also possible to use menus and chapters, similiar to DVDs, on a SVCD and also simple photo album/slide shows with background audio. The quality of a SVCD is much better than a VCD, especially much more sharpen picture than a VCD because of the higher resolution. But the quality depends how many minutes you choose to store on a CD, less minutes/CD generally means higher quality.

SVCDs can be played on

- Many standalone DVD Players, check here for compability list
- All CD-ROMa/DVD-ROMs can play SVCDs with a software DVD/SVCD-Player

If your DVD Player does not support SVCD you can try this VCD header trick, it requires no reconverting which mean that you do not lose any quality.

What is CVD then?
CVD is basicly the same as SVCD but with a lower video resolution. Using a lower resolution you get more data for each pixel which means less mpeg artifacts such as blockiness compared to a SVCD with the same bitrate, but you will lose some sharpness. Most SVCD capable standalone DVD Players supports CVD. Download a CVD sample here. Read this CVD article for more detailed info.
