delay time

Dear List,

I am making a video interactive installation. I use a DV camera(Canon
DM-XM2) to catch the image behind the screen and sent it to a projector
opposited the screen. Now I got a big delay problem with the DV camera. It
cause the interaction can not happen accurately. By the way, the lowest
resolution of the DV is 640* 480. I am wonderring what the normal delay
time will be?

Any help would be appreciated very much!

Best,

Xinmei

soooo…. seeing as how milton has yet to update the outcastsoft DFG
driver, what video-in options are there for slotless macintoshes?
(not counting IIDC cameras)

What do you mean? Version 3 of the driver was released last week (and
was beta tested in Jitter UB).

so to answer your question Xinmei, you will need to use a non-compressed video source like the DFG/1394 Video-to-FireWire converter ($350) or the Unibrain Fire-i camera ($100) to cut out the delay.
good luck!

You can also use an ImagingSource camera since it is uncompressed as well.
