breakpoint 07 amiga compos

category: general [glöplog]
ryg: I don't want to spoil the fun here, but the xvid videos on untergrund.net all seem to be 25fps deinterlaced. so much for that :)

The fact remains tho: all our Amiga/C64/console recordings were frame-perfect 50Hz DV (with perhaps one dropped frame every 10 secs because of the timing differenced between actual PAL and the "noninterlaced" version of it the C64 and Amiga output). Now we're desperately trying to find a means to play them back without stuttering, and which fits into our A/V pipeline. No, simply hooking a PAL source to the main projector won't work, as simple as it would be. What we need is a RBGHV signal; 576p@50 would be best but 576i@50 might also work. Any ideas?

Just travel back to the 90ies and buy a pristince PAL projector with nice projection tubes.

That'd be no problem - even nowadays' projectors have got fbas/svideo inputs which they can display pretty well. I'd just have to press one button at the remote and there it is - a crystal clear C64 image.

But now tell me how to do that at a party location with three projectors in three different rooms plus the feed that goes to demoscene.tv without wasting four people, a few hundreds of meters of cable and at least two expensive signal repeaters for this.

...or just ditch the compos for these nitpicky whiny ingrates and make them organize it themselves -out of their own pockets.

What? Come on here, if Scamp's multi-post angst is actually true, we're dealing with an absurd portion of time, money and effort being pumped into fueling competitions the "true" believers are whining about constantly. If that chunk of money is vested in more meaningful goals or *gasp* a reduction of the entrance fee... who would care again?

Clearly not people like Oswald :)

Hey, cool, this sounds like - basically any compo on a demoparty?

That's the next step. Boozembly was ahead of it's time.

nah. personally, i'm pretty glad that most demoscene ppl have that certaing thing that sets them apart from the other ppl i booze with :)

Which is why BZM is not like a crappy dive in Hamburg where you pick up flaky girls ;)

how about deinterlacing to progressive 50fps?

on a pc i mean

Besides, replying to Oswald's point about darkening and invisible starfields: Aren't the projector conditions pretty much something you, as a coder, should take into account and code conservatively for?

I mean pretty much every serious party-going coder should know about that already. The platform is machine + big-screen, not machine + home tv.

From what I've been told (reliable sources here) the video recordings are adjusted for optimum brightness and/or contrast given the lighting conditions, and they do cover up the windows. It's not like those starfields were incredibly clear in the good old days of properly connected PAL projectors anyway. There are other light sources in the hall too, mind you.

Anyway, I have the final solution right here:

scamp, just what are you suggesting with "pc demos are able to load realtime" ? c64 demos arent ? :)

I'm sorry, looks like I've hurt too many ppls feelings with my harsh comments. I understand that you have a lot of work in organising. Please you too try to understand that there's a lot of work in a decent demo, and its disappointing if a part of it is invisible on the big screen.

I'm wondering how all the amiga dot effects looked like on the big screen back in the early ninetees, anyone seen them IRL ?

Doom: Stop revealing our next demo!

;)
Oswald: dot-effects have never really been visible on a bigscreen, so that's why smart people avoid them in partydemos :)

dodke: that's what we did last year. After finding out how to make a PC output a 50Hz signal, that is. And after finding a TFT display for us that was able to SHOW that 50hz signal (the projectors did so without problems :). And before we had to recognize no freaking video player was able to keep up with 50fps DV-AVI material (MS's VMR9 renderer does the conversion to 50hz progressive automatically if you ask it nicely) without the occasional stutter.

Reencoding everything to high-bitrate 576p@50 Xvid before showing would be a solution in theory, only that it would take far too long to fit into our already packed to death deadline->recording->compo schedule.

britelite, hmm the number of smart ppl must have been increased significantly since the amiga dot era.

oswald: yeah, because mensa has done scientific research while kb remains refreshing unscientifically.
at least i'm grammatic correctally! :)

Hello,
the BP07-OrgaTeam told me now that they will have enough Amigahardware like a classic Amiga with PPC and enough help too.

So I think we will have a nice party next year! :)

Now, who was gonna make that PPC demo again? hmm? what? no-one? awwwww
