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.

Great idea !
Why not making a VCD furthermore ? (more compatible way to view it and the 352*288 (PAL) resolution is enough...) |

I've never heard of a dvd with c64 productions, I do now there is something for the pc scene though .. Such a dvd for c64 would be cool, but there is one small problem: most (older) demos depend on some user interaction (spacebars or joystick wiggling in order to change the parameters of some effect) so how to handle that? |

using some interactivity...
Making looping video of a demo part and when the viewer wants to go to next part, let him press the >>next key ? |

Actually that is not a bad idea but that still doesn't solve the changing parameters problem. Granted, there are not too many demos using that, but some demos thrive on joystick input. |

I mean : capturing all demo parts individually in a MPEG1/2 file each and when authoring the DVD/VCD/..., convert the MPEG files in looping MPEG videos. Then use interactivity possibilities of a DVD/VCD player to chain all the stuffs. |

I was thinking of simple brute force. I love to watch 'em anyway. I'd probably run the majority on an EMU and output that way, I could manually interact to demonstrate the features and index each demo part for jumping around ... since I'm in NTSCLand and 99% of the demos I would want to feature are in PALand I'd need to use some sort of EMU anyway ... |

yes, but what dark judge meant, are parts where you can change parameters within one part with joystick, for example changing the speed of splitbar-moving oder multiplexed sprite-movement. that's something you can't consider in a video/mpeg file. but anyway, that's a fact you can live with, regarded to the possibility of having lots of demos on dvd. :)

I'm only not real crazy about using an EMU in this case though, esp. graphics will suffer. |

SOUND will suffer.
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. |

OK, I haven't understood this way ;o)
is it so important to change scrolls speed or sprite movements in an interactive way ?
Just do it while capturing... |

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... |

yep check this site : www.vcdeasy.org ;o)
yes you can make interactive VCDs (motion menu, chapters selections...)

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).

well divx format is far better than vcd =)
and u wouldn't even need anything to capture the demo's theres such programs which do such things.. snag it etc...
more fun would be to use stereo pc versions of the sid tunes |

I wonder which selection of demos you guys had in mind. I was thinking of throwing (bits of demos) on screen at parties, but I was wondering which C64 demos would appeal to- or fascinate "normal" audience... |

everybody love this idea it seems. ;-) i ussualy use my hp 735 photocamera to make some small videos too and the sound quality is very good. lateron i work it out with a program like virtual dub.
ofcourse it's not the highest quality but you can add the original music of the demo when saving the sid file into a wav file and save it in the movie-demo. the compression is very good.
-2 start press any key..where is the any key?- |

Same here. Have one tape of demos recorded. Did it for fun and to spin some friends out. :)
