firewire DV output
Jun 20th, 2007, 6:34pm  
This question comes from an utter newbie -- I have looked around for any solutions for getting FireWire DV output from a Processing window and haven't found anything yet. I'd like to open a window in NTSC or PAL resolution and have it mirrored to FireWire so I can record it with a DV cam.

Can anyone tell me if this is a possibility?

thanks
Matt

As far as i know, there is no firewire export in P5

You can save the sketch window as a movie and export it to tape as DV Stream with an editing software.

You can do this with an ADVC such as the Canpous advc-50.  Plug it into your SVIDEO output on your computer, it will convert that to DV stream.

Movax : that's also a solution (can be also done with a MiniDV camera), but i worry about 1 generation loss caused by the analog2digital conversion.

The solution i was talking to is to keep the recording quality real close to the original.

I'm used to do this on OS X,

I think it is possible to use this exemple to make a videoOut library that will send the sketch straight to the a firewire data stream.

This looks very promising! Thank you. I don't think I have the time or skills to try and build it into Processing however. Anyone else!

I did notice the MovieMaker library though, which might at least let me write a full-frame QuickTime movie for later exporting.
