[Larry Watts] “How big a role does the card play in a typical edit?”
Capture…output…view your footage on an external monitor…take the task of unsqueezing anamorphic footage off of the computer and GFX card and shouldering it.
[Larry Watts] ” In a DV or HDV world does it allow the timeline in Final Cut run smoother without dropping frames to go directly to tape? “
No. It allows you to output to non-firewire sources. And capture from non-firewire sources. And upconvert SD to HD, HD to SD, cross convert 720p to 1080i. Capture HDV as ProRes…
[Larry Watts] “Does it speed up renders to QT files, or FLV? “
No.
[Larry Watts] “Does it lighten the load off the processors? “
Yes…when it comes to anamorphic footage, as mentioned above.
