After reviewing my requirements, I doubt I will need to work in 444 for any broadcast production. My source is currently 422.

The stereo channels which come with the AJA LHe are fine. I only wanted to have the ability to work with 8 channels if needed.
-
So the product may work well with my system configuration.

I have been interested in the Mackie Onyx 1200F FireWire audio interface. This would be replace the audio from the Xena card and provide (192khz 24-bit). Al though, I am not sure if it would cause any issues since it is based on Firewire.

That is a question that I don’t have an answer. Good reason why not to use compressed codecs and stick to the uncompressed format that AJA supports.
-
How would you compare the audio from a professional audio card to the audio from the Xena card? I would expect it would be about the same (16/24-bit 48khz).

Yes, there is a big difference with compressed and uncompressed. I figured I would need at least 16TB to work in an uncompressed environment without running in space issues. The good news is that SATA 3.0 drives are larger and cheaper now. Raid 5 or 6 is good.
I almost did not purchase Cineform until I found that I could preview unrendered video using control-spacebar. Of course, it leaves out frames but it gives me a clue on how the effect might look.

I have found when using the Adaptec SATA II 8-port raid that the computer is able to keep up. Al though, I would highly recommend a 16-port raid card if using SATA II drives at 7200rpm.
The only issue that I ran into is that 2TB is not nearly enough space for uncompressed video. It would cost at least 6k to build an internal raid that would provide around 16TB. Oh, you can’t exclude the 18 bay case and 1000w power supply.
Cineform Prospect 2K seems to be fine with 2TB, but you lose some of the realtime previews when adding effects.

I never thought about that approach. So replacing my Sound Blaster with a professional audio could would resolve my audio issue. Have you had any audio sync issues by not using the audio on the AJA card?
So that leaves me with one last question. Do I really need 4:4:4 color compared to 4:2:2 color? I have always used 4:2:0 or 4:2:2. So have no reference to the different between 4:4:4 and 4:2:2. Al though, I do plan to work with animation and CG and believe that preview the actual color would be important. I noticed the AJA 2K says that it is broadcast quality. The AJA LHe doesn’t mention broadcast. It seems that having 12 bit color would be important when working with motion picture. What about broadcast? Sorry for running on and on… but how important or not important is it to edit in 4:4:4?

Thank you for your input. That will be helpful when making a decision to purchase Sapphire.
