Demo DVD?
Has anyone taken on the ambition of recording the top demos to a video and/or DVD? I would love to have a compilation so people can enjoy the top productions anywhere they choose. I also think it would be great background material ... for example, throw a party, toss the demos on the big screen with some funky SID background muzak ...
At any rate, if this has already been done, I'd love to find out where I can get my copy! If it hasn't, then this is a project I'll definitely consider working on.

although, yes, gfx may suffer too, they won't suffer as much as sound will....
in general a vcd (or even more) with c64 demos on it would be cool. Must go and ask friend of me if his tv-card works again.
Personnaly I think VCD would be better :
more compatible (DVD/VCD player /PC-MAC without DVD-ROM)
low cost production
more easily spreadable
interactive possibilities (with the great tool : VCDEasy)
enough good resolution (352*288 PAL, 352*240 NTSC)
and a 80 minutes show on a 700Mo CD... |

In the past (5-6 years ago), I wanted to record on a VHS my favourite demos, game-intros/end sequences..., all the cool stuffs I enjoyed to watch on my C64.
With this posted subject the idea came back in my mind...

The only major problem is the compression format of MPG1, MPG2. It is only suited for Video/Photoquality images and not Semi Static Data.
Using A compression format such as AnimGIF might improve the compression ratio considering that most demo's feature static logo's or scrolling of static data.
The compressor will simply analyse the next frame and only the differences will be encoded.
Using MPEG will result in blurriness and artifacts particularly at the edges of text or sharp gfx images.

Yep ! You're right ! :o(
But what kind of anim/video file is more suitable for this kind of project ?
Apart capturing the C64 video source and converting it in MPEG I don't see... |

I am not entirely sure myself, but it would certainly be one of the non-lossy codecs rather than MPG/DivX etc.
Maybe HUFFYUV, MSVIDEO, I will experiment with this myself.
The compression ratio should be amazing only if the codec has the ability to analyse and compare image data with the next one.
Imagine a logo which moves 1 pixel horizontally to the right every frame... As the logo is still the same, additional data is not required for this.
For the time being, just save around 10 seconds of action in uncompressed AVI and use a program such as Virtual Dub to recompress in various formats and inspect each one in quality and final filesize.

the problem with other codecs and the idea behind vcd/svcd is the im/possibility to watch those movies not only on your pc but also on standard dvd players etc. |

You are absolutely right. It seems that MPG1, MPG2 is the only option in that case altough a ISO9660 DVD packed with video sequences in another codec can be displayed via projector/tv out etc.

Guys, just keep in mind that the guys that made the PC demo DVD (www.mindcandydvd.com) are also planning to do similar things for c64 & amiga demos (see www.demodvd.org and the mindcandy forums).
