I capture 720p 50 with a blackmagic card. When I try to capture the video via the write command I have a delay of nearly 2 secs until the capture actually starts (on a Mac Pro with 10.6, 2×2,93 Quad Core Intel Xeon)
I did not have that prob on another mac pro with with 10.5 on it, a bit lower processor speed but with a RAID system. Do you think it´s because of the RAID or does MAX simply prefer Quicktime 7 (of Leopard) over Quicktime X (of Snow Leopard).
we switched now to a mac 2,8 Ghz Quad Core Intel Xeon. That generation (Early 2008) has no delay at all. The new Mac had delay also after driver update and firmware update of the Blackmagic Card.
Still having the same problem on a MacBook Pro, Late 2007 with 2.2 Ghz and 4 GB of RAM, running OS X 10.6.8 and QuickTime 10.0.
Additionally when I open the recorded .mov in Quicktime and look at the movie information, I see that it has strange framerates like 14.57 and the video is stuttering and incomplete. (Although I send the write message with, say 25. as framerate setting!)
