Memory requirements for new noise reduction? Seem very high…
Hi all!
I am wondering is there is something wrong with my system (drivers etc.)
I have 5K footage going down to a 1080p timeline.
When I apply the new motion-based noise reduction, I quickly run out of GPU memory, even though I have a 2.5 Gig card, and this even if there si only one other node. What are the requirements for using motion noise reduction on large-res origin files?

The 6gb titans work well

More gigs. 2.5GB is on the cusp for HD use, when using the NR or optical flow. This is a big part of the reason I recommend the Titan or K6000. Those 6GB or 12GB are a big benefit.

was wondering if the titan is similarly going to help out with RAW formats like .ari files
how many GFX cards do you find you need for decoding and grading raw formats or is a single titan going to do that?

I always thought memory requirements were tied to timeline resolution, not source footage resolution. Is this not the case for the new NR? If it is not we can all forget using it with Dragon footage. Who about optical time-warps? DO they look at the source footage resolution, or the timeline?

We use the RED SDK, as everyone does, for r3d files. Other RAW images are debayered in GPU, then re-sized to the timeline res… where the image processing, inc temporal NR and speed changes, occurs.
So the GPU ram size and core count is important in many respects.

Peter”OK, so… who much memory do I need to use temporal noise red. on Red 5K for a 1080p timeline? In other words, when it comes to GPU RAM requirements, is it the resolution of the timeline that is important for Red footage, or the resolution of the source footage?
BTW – I must say the new curves in latest build are great – much less noise than ever.
