VP14: 4K Upscaling and GPU Requirement?

dalemccl wrote on 11/27/2016, 4:13 PM

One feature of VP 14 that interests me in upgrading from VP13 is the new 4k upscaling. I have a new 4k TV and most of my older footage is 1080p. (Let's set aside for the moment the question of whether the upscaling effect would be noticable.)

I have read that the 4k upscaling feature only works with GPU acceleration. Does this mean the feature only works with the same video cards that are supported for rendering and the preview window in VP13, which would mean my GTX970 isn't supported for upscaling and I would not be able to use the feature?

Rendering, aka encoding/saving a specific file type, is separate from all other video processing. If your GPU is supported by Vegas GPU acceleration for video processing you should be good to go with that feature. The GTX 970 should be fine with proper drivers. My GTX 980 works in Vegas for GPU accel (video prefs) in VP13.

Some Windows updates have been known to delete the Nvidia OpenCL driver and thus Vegas will not recoginze the video card for video processing accel. It happened to me once. Just reinstall the Nvidia driver.

Thanks, Norm. I shouldn't have said my GTX760 isn't supported in VP13. I should have said rendering and playback aren't any faster than with the CPU, and sometimes is slower or causes problems, so I disabled the GPU in VP13 long ago.

Hopefully the GTX970 is enough to satisfy the VP14 requirement to use GPU acceleration for 4k upscaling. I installed the VP14 trial to check it to see if there is any noticable improvement in 1080p upscaled to UHD, but 3820x2160 rendering is not available in the trial -- 1080 is the highest resolution available

It's the first I've heard of that. What render format? If it's MainConcept AVC then you have to manually type in UHD resolutions, even in the retail version. See section 3 in this post.

I apologize for the misinformation I posted. I went back and looked again at the help screen for 4k upscaling and followed the steps correctly this time and all is well. 3820x2160 is available in the trial.
