so i just bought the capture card and got it up and running today, and i was recording video from it to my Mac OS X. pretty soon after the record stop itself and tells me startup disc space was almost full which didn't seem right at all because i had nearly 39GB left on my hard drive. so i look at the video file i was recording and the file was huge for only being captured for 5 min, several gigs worth. which still didn't explain why my hard drive was almost full. but then after that i couldn't record very long and the file sizes remained to be very large.
i was wondering what settings i could put the video and audio on to keep the quality normal and the file size minimal. because i really don't see why it would need to take up so much.

Hi Joe,
I am sorry for the late reply. There was an issue with the response forwarder.
The ProView USB is unique in that it actually has the ability (and defaults that way) to capture full 4:2:2 RAW (that's uncompressed) full screen video into your Mac. The great part is that you get perfect quality. The downside, being that the file sizes are HUGE.
But, the XLR8 ProView USB also fully supports QuickTime. That means that since the device does no compression itself, you can compress to any QuickTime format with only a single generation loss.
While H.264 (or Apple Intermediate) are excellent, they do consume a lot of CPU cycles to compress on the fly, during capture. If you have very fast drives, good RAM and a fast CPU, go for it.
Otherwise, I prefer Photo JPEG for a capture and editing choice. You can adjust the quality choices via the sliders in the capture software. The mid-range is very good, while the 'better' setting will create near perfect frames, and video. JPEG is very light on the CPU, and save tremendous space.
Thanks for your support of our products!

Gary -
I tried what you suggested - putting the capture in Photo JPEG compression and changed the settings to a lower quality (from best to 50 frames per second, and from best to better on the depth. I left the size at 640 x 800).
This reduced an uncompressed 19.5GB quicktime movie file to 9.4GB. Obviously, I'm trying to capture whole VHS movies and transfer to DVD.
What additional compression ideas do you have to help get the filesize under 4.7GB so it'll fit on a single DVD??
I've a new Macbook Pro (17") with the upgraded 4GB of RAM. As far as I know, this is the fastest Macbook available.
I haven't tried other compression techniques yet, as you suggested Photo JPEG as your preferred. Please help!!

| Once you have captured the file, then use the exporter utility, or better yet, QuickTime Pro to convert using H.264. Last edited on Sat Jan 12th, 2008 08:56 pm by Gary

I appreciate your patience...since I'm a neophite! I suppose I need to purchase Quicktime Pro - no biggie. But does Quicktime Pro take an existing file then compress it again?? How's that done?

Actually,
If you are trying to go DVD. You should simply take whatever you capture and use IDVD to get to DVD. The compression used by IDVD will fit it on the DVD.

Hi;
Sorry to barge in but this conversation but this is exactly the issue I have.
I just purchased my first Mac. It's a Mac 10 Pro with two 2.66ghz Dual Corr Processors and 1gb of ram.
There is nothing in the computer except one 52minute video transfer and Final Cut Pro.
The video I transfered using the XLR8 was huge.
I tried to cut it up and crunch it using Quicktime pro and that does not seem to work.
I also noticed that this device completely dominated the computer to the point where you cannot use it while it is transfering.
Has anyone come up with a solution yet?
