we have a fiber connection with a 4g fiber card connected to an adtx raid and their is plenty of through put. I have nothing else connected to the computer at the time of capture. if i take it in HDV it works fine. i tried a few different tapes and each one closes FCP at a different point. Sometimes it’s 5 minutes or 8 minutes into capture. the capture screen always says that the capture is in real time as well….I did however capture a few tapes that was shot HDV 24p and took it in firewire and was apple to capture what i needed about 6 minutes, with no problem using the prores 422 hq 1080i 24p……..
I am using the aja Kona seq prores 422 1081 HQ
Capture preset HDV – apple prores 422 HQ
