Diane,
[Diane Wilkins] “I spent lots of time looking at AXIO LE (analog component input, but only compressed HD. right?).”
If you’re worried about the quality of Matrox’s MPEG2 I-frame codec on the LE, don’t. It is extremely good. A friend’s friend who’s a top flight engineer spent a lot of time testing the codec up one side and down other. His conclusion was that at 200 mbps or over (LE takes the codec up to 300 mbps) the codec was indistiguishable from uncompressed both visually and technically. The codec might show wear over multiple generations, but compositing now-a-days is so sophisticated that it seldom demands more than one pass.
However, (and I don’t think that this was available initially), the LE now can do uncompressed HD as well but it’s limited to 8 bit bit depth. The bit depth is the key differentiator in the Axio product line at this point. The AxioLE is limited to 8 bit all around, the AxioSD can do 10 bit SD, but only 8 bit HD, and the AxioHD can do 10 bit in both SD and HD. Unless you’re doing network level compositing, both uncompressed and 10 bit HD are rather overkill.
So unless you have or expect to have clients who demand 10 bit HD your final product won’t suffer and your investment in Axio from puchasing the LE over the HD will be considerably less with more diverse I/O.

Terje,
[Terje A. Bergesen] “There is no reason that a 64 bit version of Vegas would use your cores better than a 32 bit version.”
OK, thanks! Would a 64 bit system be more efficient in processing real-time effects and compositing, and without the 64 bit system would a quad core processor perform appreciably faster with Vegas than a dual core, than on the same MOBO with comparable clock speeds?

Fuddam,
[Fuddam] “is now an E6600 with 2GB, so quite a difference from the old beast.”
Hmmm! It’s a little disconcerting that the E6700 w/2GB that I’m putting together for Vegas won’t work appreciably better in this situation than your machine. Probably Vegas won’t use both cores well until the 64 bit version. We’ll see.
Thanks for the update.

Fuddam,
[Fuddam] “turns out the render to SD AVI is fine, so no worries then :)”
Excellent!
[Fuddam] “Is a fast machine, by the way.”
If it’s the machine in your profile, it’s a pretty modest ‘puter by todays standards with lower than average memory. Scaling is pretty processor intensive and I don’t think that it’s unusual that this processor couldn’t handle it better in RT. I’m wondering if dual proc systems do a considerably better job, and would more system memory help appreciably?

Fuddam,
[Fuddam] “the jaggies only happen when imported into the DV project”
I’m curious about this. Have you tried rendering a portion of the timeline of this DV project including both SD and HD material to DV and/or HDV to determine if it’s only a preview problem? Perhaps when it’s a mixed timeline there’s too much manipulation happening for Vegas to do a very good job with RT preview. On a pure HDV project there’s no scaling involved.

[Inversified] “I have no clue why, I’ve been searching for several days now with no answer.”
Just a thought, but some inboard audio on motherboards can cause this. An inexpensive sound card may solve the problem. What’s your system specs?

Surfer,
[surferj45] “Now, in this configuration which drive is best to render to?”
As far as the basic operation of Vegas it doesn’t really matter, but for your media management it might be easier to have it on your library/scratch drive as Raymond and I explain below. It could also make things easier if you set 2 partitians on this drive, 1 for the library, and the other for renders and such.

Raymond,
[Raymond Motion Pictures] “Personally, I render to another drive because when I wipe my capture drive clean for the next project, I don’t want to inadvertently delete rendered files for DVD or Flash Video – so I keep them separate for that reason and, pretty much, for that reason alone.”
The other reason is that it is also an aid in archiving a project where you don’t need to archive the timecoded capture files because they can be recaptured from tape if you need to return to the project later.

Raymond,
[Raymond Motion Pictures] “I also have two Raids of two HD’s each (two teras total) for video capture.”
If you’re only working DV/HDV then 2 raid 0s of 2 drives each is a good way to work because you can move files from one to the other to clear off a set for reformating if fragmentation becomes too much of an issue.
