Live

Hello,

I'm looking to freeze a live input (video input or BlackSyphon as we're using Intensity Extreme cards) with a trigger.

I guess I should use an accumulator but I'm new to this.

Could the frame just be held in memory or should it be sent to the hard drive?

Ideally there would be a simple toggle to hold and release the frame, just as you hit play/pause in QuickTime Player for example, but with live video.

Thanks for the help.

I was curious if anybody else had made a composition in Quartz Composer for VJ or live video purposes?

I have found this to be one of the easiest environments to work in and I was curious if anybody had applied this ease to a full program that was robust and reliable enough to be used in live productions?

I have been using the stock Black and White patch to render any photo/video in BNW, however, this seems to be very costly to the CPU when used in a live video sense. Iw as wondering if there were any more effective ways to render a image source Black and White?

When I switch to BNW now I lose easily 50% of the frame rate and I know there must be a better way to do this. Any suggestions are much appreciated!

Just wanted to share the newest version of my video mapping software that was built in Quartz Composer. Mappit, as I call it, aims to be an entry level program useful for mapping out surfaces, building, shapes, etc with a projector. I consider it a very handy tool and I am sure someone will be able to make use of it.

In this version there are several upgrades including the interface, and the ways in which Mapp's are assembled and moved. This is of course free, and couldn't have been without the great help from this community.

Enjoy

I am looking for a good way to "scratch video" in QC. By scratch, I mean analogous to Dj scratching in that one can alter the speed, position, and direction of a video on the fly using some fader, rotary, or other controller.

I have looked around, and it seems as though dust made it pretty good with his approach but I found no file to dive into. http://kineme.net/forum/Programming/bestapproachtovideoscratchplugin

The internet hints at using some sort of queue system to drive the video's position from what I have gathered.

Of course, if I hook up the mouse input to the rate, or selection start, the video becomes choppy. I know there is a good way to do this.

If someone could point me in the right direction that would be much appreciated
