Using Aspect HD with Conroe CPU
I know Steven Gotz is a huge fan of using Aspect HD with PPo, so this post is for him. Can you explain why I can only get 3 layers of Cineform video (w/dissolves) in realtime using a Conroe E6400 CPU and a SATA II drive? This CPU is faster than any other dual processors our there, other than faster Conroe CPUs that is, and my drive has sustained throughput of 78 MB/S.

Interesting question. I have heard and seen rave reviews about this chip. How much memory are you using?

I have 2GB of DDR2 PC5300 RAM in the system.

What is puzzling is the fact I get the same performance using PPro 2 in native HDV mode (CPU usage is about 70% max when rendering). So, this makes investing in Aspect HD a waste of money (I am using the trial version at the moment).

Aspect HD also interpolates the 4:2:0 HDV into 4:2:2 and enables all your internal processing to take place in this better color space which has double the chroma resolution.
So maybe there is a little more processing time with Cineform due to the doubled chroma resolution and that offsets Cineform’s otherwise timeline friendly intra-frame encoding.

I am away at a funeral this week. I don’t have your answer, but when I get back, perhaps I can get the CTO of Cineform to take a look. He specifically told me to get the Conroe EE, which I am getting. The regular Conroe should be pretty good as well, but I can only go with what I am told. Cineform tested the Conroe before its official release.
I would imagine that 3 layers would require a RAID0, but I really can’t swear to it. I just don’t have the info with me.

How did you test the output of your drive?
SATA 2 is supposed to run around 3 Gbps (375 MB/s) I thought…
It isn’t your C: drive is it?

I used a software app called Rextest for testing…the drive is in IDE mode on the MB controller at the moment…will be adding a RAID card next week to take advantage of the higher throughput of SATA II and stripping with an identical drive for this purpose. However, the performance I’ve mentioned with Cineform should still be better than what I’m currently getting, no?

I would think that you should do a little better than you’re doing, yes. It makes me wonder if there is some inherent bottleneck internally with the pipeline to the drive…

Which resolution and frame rate? What is the data rate of your source files? It seems that the 78MB/s drive speed would be a straight line speed, and playing multiple video clips requires a lot of seeking for video and audio streams (which Premiere stores separately.) You can definitely do more than 3 streams on that system with the drive throughput to match.

I’m using Aspect HD 1440×1080 60i. Files are HDV from a SONY HC-1.
