It's not I'm too lazy to do own researches, but maybe you guys have some experience for helping me with the project I'm planning.
I want to use a live cam on a theatre stage, stream the video signal into Pd, add some (maybe audiowise triggered) effects and put the signal to some older TVs on stage in (almost) real time. As you can probably imagine with as low latency as possible, but it hasn't to be perfect.
We have a Canon Legria HF R26 camera (which gives out HDMI and Composite video) and some Composite switches (cinch to cinch). As far as I know now, Composite is more reliable than HDMI on growing cable distances, so the quesion for is:
How to get the signal into the computer and out without having too much latency? I probably would need to buy some kind of video grabber (card or composite to USB?). Please note we are a small theatre group which needs to save every coin we can, so we can't pay 300$ for some Matrox device...
Could you give me some hints for more affordable but also reliable hardware to work with?
Thanks in advance!
