Uncompressed HD over firewire?
Hi,
The new AJA IO HD looks great but I’m confused as Uncompressed HD can be more than 100mb/sec yet firewire800 is only 100mb/sec. How does this work or does it not actially do uncompressed?
Thanks

Only Apple ProRes 4:2:2 10bit for HD. Does Uncompressed SD.

Firewire 800 is 800mb/sec. It’s also 100MB/sec. In an ideal world that is. 🙂

Firewire 800 is meant to be twice the speed of firewire 400 which has a speed of 50mb/sec, the 800 mean 800mbits/sec which is slower than a mb.

Jason, You’re missing the point, get your bits and bytes right.
A mb is a mega *bit* (or 1/8th of a megabyte), a MB is a mega *byte* (or 8 megabits). FW400 has a theoretical speed of 400mb, or 50MB. For FW800 it’s 800mb, or 100MB.
