VVVV Mapping -> DVD

I was wondering if anyone has come up with a successful workflow to get mapped content on to a DVD?

To clarify wht I want:
the projector is in place, the computer is used to calibrate the content, which is then rendered to DVD, the projector is source switched to a DVD player with the new DVD.

I thought this would be quite straight forward, but after repeated attempts I’m pulling my hair out…

Well, first you need to record the renderer, and than burn it to DVD, or get an external DVD/HD recorder.

Here are some suggestions to capture the screen:

My favourite tool for this is called Fraps, and than with NERO you should come a long way.

and since you are mapping and than go to DVD, make sure the Rendersize is already PAL (or NTSC).

Hehe, i hope you aren’t already aware of old nice croped picture translation by dvd player, don’t worry it just a little bit f^ckt yp so don’t relay on percission ;]

good luck! :)

Thanks for the speedy responses.

In general, I’m fine to get content on to a DVD using:

Its getting precision thats turned out to be nasty. Getting the right transcoding setting helped, changing the nvidia settings for size and position helped (they seemed to be slightly cropped to begin with). But its still really not good enough to make me happy for mapping.

I tried several DVD authoring programs and it seems like there is a small distortion even when they are being fed a DVD complaint file. The distortion is then made even worse by the DVD hardware itself. I’ve only one DVD player to test with at the moment so I’m not sure if this varies much from machine to machine.

At the moment I’m thinking a work-around might be to measure the final DVD distortion with a test grid on a whiteboard, and make a render transformation from them. Could maybe then warp the content whilst its rendering. hmmm, not sure if that would work but I’ll give it a try.

Good article, I learnt a lot from that…

I’ve made a calibration patch (ie just a test image to spit out to dvd), I’ll see if that gets the job done.
