1) I'm using quartz composer to render the video to be displayed at 1024x768, with each of the 4 inputs showing below it at 256x192. My idea is to render this all in a viewport of 1024x960, and then crop it and put each section into a window, scaling the large video to also put a preview onto the controller screen. Is this the best way to do this, and how do I go about the cropping and embedding?
2) I know that uncompressed video takes up a lot of space over firewire. For 4 cameras that send video at an unknown size (I think they'll be analog, so they'll be through component cables), what do I need to do to make sure that I can get all the various streams without delay and at at least 1024x768? Is there anything I can use (some sort of hardware) so that I don't have to potentially buy an extra firewire card for my computer? Or will this not be a problem??
3) I want to have some way of creating a table in the application that you can put data in, that will be sent to the quartz composition for use whilst rendering. I need it to be able to reorder the rows, but other than that I just need to be able to send all the data in multidimensional arrays. I know of the Chart application from the examples, but how do I enable reordering?
4) The video input patch in quartz composer has that wonderful input selection tool, but how do I get that in my application? Once again, I know there's an example of it, but I can't make heads or tails of how it's worth. If someone can give me a prod in the right direction on this, I can probably take it from there.
As always, thanks for any and all of your help. Namaste, Karan
