anix,
that is a wonderful idea.
What about re-recording it with pal-emulation at high res and send someone as AVI who could host? :))

@enthusi

winvice 2.0, when i have the recorder on and try to use the doublesize+pal, it crashes. at least on this machine. i don't think the extra "quality" would matter, the real magic is in the ambiance of the crowd, and the scenesat guys managed an excellent quality recording of the hardware sid. since it's just 1:1 size, i didn't bother with the pal emulation because you get duller colors without the real benefit of the line renderer.

AVI's are comming up, i'm getting three torrent seeding on three hosts before i give out the .torrent.

i'm thinking about doing the same thing for a few other demos which had live-video, and cutting out the audio and making similar avi's. off the top of my head i know that the floppy 04 entries could be done, krill's 4k from BP, desert dream...

anyone know others that have available live sound?

.torrent url is on the csdb mainpage. i didn't bother with a tracker - i can keep a couple seeds up for a few weeks and maybe someone can put the files in a better place if they like.

Just a little background info on the process I use.

Hardware set up:
* Commodore 64 (any required sid)
* C64 DIN->SVideo Cable
* Canopus ADVC110 (analog to digital converter)
* ADVC110 Firewire Output --> PC
* Composite output from ADVC110 --> 1084s-D1 Commodore Monitor

Software:
* Ulead or Pinnacle Studio - to capture PAL signal
* AviSynth - to fix the interlacing problem of the C64 PAL signal (convert to 50 fps frame-based), and to crop only the C64 visible screen resolution (including sideborders)
* VirtualDub - To process the raw AviSyth scripted video, separate audio for syncing, merge with synced audio, compress to DivX format
* Cool Edit Pro - To align the out-of-sync audio with an audio sample that was in sync (using ADVC110's audio lock setting).

The ADVC110 has audio lock that will force the audio to align neatly with the video. This may be great for movies, but sucks if you record music. The process causes small gaps to appear in the audio signal, very subtle, but you hear them nonetheless. This ruins the experience of any good SID tune, and being a SID musician myself, this is out of the question.

So I record each demo twice, one with the ADVC110 audio lock on and one with it off. This way I have an aligned audio signal and one that is not, but is at least a perfect recording.

Cool Edit Pro has a er.. cool...option to stretch an audio sample without harming the pitch. To align an out of sync signal with a demo video it takes only a stretching of 0.5-2 seconds depending on the length of the demo. This works surprisingly well, in Cool Edit's multitrack mode the result is immediately visible and I can check whether the new sample aligns with the audio-locked one.

I then replace the audio-locked one with the new one using VirtualDub and done. ;)

Bah, another reason to host these AVI's ourselves is instant upload. I've already fixed that small sync issue with EoD and uploaded the new, higher quality AVI to demoscene.tv, but it still has not been posted there by DTV, much to my impatience.

You Tube has limited the duration of footage to 10 minutes, so Edge of Disgrace in one go would not be possible and it sucks to have to cut it.

Perhaps google video is faster. Will check tonight. Cause I have much more to record.

Google video encodes the video far better and in stereo (although SID is in mono)
