Video card survey: SVP11 and CUDA acceleration

[Angelo Mike]

I’ve given my thoughts many times already, so at the risk of boring everyone, I found multicam editing on Vegas 9 and 10 very smooth, even with 8 tracks of video and computer specs very similar to yours. In 11, it was so slow and choppy that it was almost unmanageable. I had video with lots of motion that I was cutting between four tracks and I was utilizing GPU acceleration with a GeForce GTS 450, but it didn’t help. It sure helped with mpeg2 rendering, it seemed, because rendering a 90 minute video for DVD took only about 30 minutes.

I switched back to Vegas 10 because of that and other issues, which were just as maddening if not more so. When they fix these problems with 11 I’ll gladly switch back.

Ok, I’m repeating myself again, but I just want to see if anyone else is having this problem-Vegas 11 made ALL my avi footage-thousands of media-and made them the incorrect aspect ratio. It’s 1440×1080 footage with an aspect ratio of 1.33. It made all that footage have an aspect ratio of 1. Not the preferences for the project, but the media itself, so I was having to right click on every piece of media and change the aspect ratio. Is there some setting in Vegas I can change for that, or did Sony royally screw that up?

For those and still other reasons, all Vegas 11 is is a loss of features and functionality. Maybe Sony will roll out an upgrade in a month if we all let them know what the issues are.

Hi,

Do you experience preview lag? Yes – but overall it’s much better than 10. I can preview in optimized mode, which was not possible for me in 10.
Are you editing multi-cam? No – but I am having lags when 2 tracks are combined through transparency (should be the same issue, as there are twice more data to handle in both cases)
Edit format: AVCHD
Multi-cam tool: none
Make and model of your video card: GTX460 (don’t remember the brand. Asus or Gigabyte)
Amount of RAM installed on your video card: 2GB

From my GPU perf monitor, I can see that lag happens even with the GPU is loaded at 6-10% only (a pitty), and the video card RAM is far from being saturated. So it looks like the bottleneck is the bus speed to transfer data between CPU and GPU (because the CPU is not fully loaded as far as I remember).

@Angelo: I don’t have the scripting API doc with me, but I am pretty sure it lets you access the aspect ratio property of an event. I am amazed that Vegas modified the input media, but if it does so, then changing this property from a script will probably update the media?

Hope this helps,
Frédéric

Along with the other problems I’m having with Vegas 11, I’m too fed up with it to take you up on that script. Thanks for the offer, though. But when I reinstalled Vegas 10, all that same footage that Vegas 11 made an incorrect aspect ratio for is now in its correct aspect ratio. Go figure, Sony made an update that undoes my work.

Do you experience preview lag? No
Are you editing multi-cam? Yes
Edit format: AVCHD
Multi-cam tool: Ultimate-S
Make and model of your video card: 2-ASUS GTX-460
Amount of RAM installed on your video card: 768MB on each

VERY similar system to yours. Windows 7 Pro (not ultimate)

I have never been an early upgrader. I usually wait for feedback. But with this upgrade to 11, my multicam is so smooth it feels like Christmas!
