What does Premiere Pro accelerate with CUDA/OpenCL?
Here’s a list of things that Premiere Pro CS5 and later can process with CUDA:some effects (complete list at the bottom of this post)
scaling (details here)
deinterlacing
blending modes
color space conversions
Premiere Pro CS5.5 and later can process even more things, listed on this page.Premiere Pro CS6 can use OpenCL to process the same features, with the exception of four effects: Basic 3D, Gaussian Blur, Fast Blur, and Directional Blur.
It’s worth mentioning one set of things that Premiere Pro doesn’t process using CUDA/OpenCL: encoding and decoding.
A common misconception is that CUDA/OpenCL processing is only used for rendering for previews. That is not true. CUDA/OpenCL processing can be used for rendering for final output, too. See this page for details about what rendering is.
Whether a segment of a sequence gets a red or yellow render bar is influenced by whether the project is set to use CUDA/OpenCL processing (i.e, whether the project’s Renderer setting is Mercury Playback Engine GPU Acceleration or Mercury Playback Engine Software Only). See this page for details.
Note that whether a frame can be processed by CUDA/OpenCL depends on the size of the frame and the amount of RAM on the graphics card (VRAM). This article gives details about that, toward the bottom.
Processing with CUDA/OpenCL doesn’t just mean that things are faster. In some cases, it can actually mean that results are better, as with scaling. See this article for details.
For export, scaling with CUDA/OpenCL is always at maximum quality, regardless of quality settings. (This only applies to scaling done on the GPU.) Maximum Render Quality can still make a difference with GPU-accelerated exports for any parts of the render that are processed on the CPU. Over time, we are working on reducing the list of exceptions to what can be processed on the GPU. For an example of a limitation that can cause some rendering to fall back to the CPU, see this article: “Maximum dimensions in Premiere Pro CS5″.
When rendering is done on the CPU with Maximum Render Quality enabled, processing is done in a linear color space (i.e., gamma = 1.0) at 32 bits per channel (bpc), which results in more realistic results, finer gradations in color, and better results for midtones. GPU-accelerated processing is always performed in a 32-bpc linear color space. To have results match between CPU rendering and GPU rendering, enable Maximum Render Quality.
Note: There are two places to enable or disable Maxium Render Quality—in the sequence settings and in the export settings. The sequence setting only applies to preview renders; the export setting (which defaults to the sequence setting) overrides the sequence setting.

Those are the “danger stripes” indicating that the track item is linked to a piece of media that doesn’t actually have audio or video that long.
Hope this helps.

Both AJA (as Walter mentioned) and Matrox allow you to select a secondary output. For Blackmagic your workaround would be to place you desired output into a matching sequence.

Hi Katy,
Sorry for your troubles. Would you mind sending me your project that crashes with the offline media files included? Also detailed steps leading up to the crash.
You can send it via dropbox or something of the sort.
If your interested please include the info here or PM the details.
Thanks!

You can make a feature request here:

Ann’s right there’s no way to do this in Premiere. Markers would be the way to go.

Hi Lucy,
C-300 files playback fine in Premiere Pro CC. New in Premiere Pro CC we offer a sync by audio feature. PluralEyes also works great in Premiere Pro CC and provides more options to options to fine tune syncing.
Hope you enjoy CC!
