“New” graphics card

[Sonic 67]

For monitoring, I use GPU-Z:

[Malcolm Matusky] “All my monitors (3) are in Card 1, and card 2 is just for graphics acceleration.”

Malcom, I wonder if the card that is used to drive the displays is really used at maximum. If I am to guess, a plain GTX750 would provide the same 4 display capability.

Just for curiosity, if you run GPU-Z while working on the project, what is the GPU load and Video Engine load for the card that drives the monitors?

I’ll have to do the GPU test, sounds interesting. Doubtful the card is maxed out, I set the driver to use both cards for CUDA, and the same setting in Davinci is possible too. “Display GPU to accelerate CPU” or something like that.

My six core CPU cannot max out my old Fermi GTX480 card (with 480 cores, modded as Quadro 6000).
I am not sure where the bottleneck is…

Sir John, (or anyone who knows)After reading the thread, I bought a Radeon R9 290 have seen a substantial difference in VP13.PC System 2
I do 4 to 6 tracks (1/2 hour program) in multicam edit mode weekly, should I convert the footage to a particular common codec before using Multicam to be more efficient.
I have 2 tracks ex1 MP4 30P 1920×1080 35Mbps –
2 Tracks 1920×1080 59.94 fps Progressive from Panasonic (I think its 50Mbps)
and 2 tracks Canon 29.97 1920×1080 AVC
I notice it starts stuttering a little in multicam – granted I may be asking much of my computer.

Also do I understand correctly color correcting before multicam is a waste as when I enable multicam I lose what I have done – or am I doing something wrong?
Thank You

I’m going to guess that the Panasonic footage is what’s causing your problem. If you are delivering 29.97fps I would convert the 59.94 fps Panasonic footage to 29.97 fps and see if that makes a difference (it should).

[Don Cobble] “Also do I understand correctly color correcting before multicam is a waste as when I enable multicam I lose what I have done – or am I doing something wrong?”

You can color correct before as long as you do this at the Media FX level. This will correct the media itself regardless of where you cut it into your project.

You should not color correct at the Track FX or Event FX level before completing your multi-cam edit because your Tracks and Events are going to change when the multi-cam is assembled and you will loose all of that work. So only work at the Media FX level before your master multi-cam tracks are complete.

I am sorry but, I don’t know what you mean Media FX Level? Are you meaning before Vegas?

What Format/Codec to convert to? Is XAVC an intermediary? I have Cineform Premium. or should match the EX1 Footage?

No, XAVC is not a digital intermediary. if it performs well on your computer and gives you the quality that you want I see no reason not to use it. A one generation render is not going show any degredation.

[Don Cobble] “I have Cineform Premium. or should match the EX1 Footage?”

Whatever works best for you. If the EX1 footage is performing well you can certainly convert it to that. Then all of your footage will be in the same format.

Where digital intermediaries like CineForm shine is when doing multiple renders. Let’s say you render to go into a special effects tool and then render out of that to go into color grading tool and then render out of that to go back into your NLE for final assembly and render. That’s when you want to use a DI like CineForm. But for a single render… use whatever works for you.
