29.97 fps with 4k

On my system, if I load a 4k video in Vegas, it will play an average of 26 fps. Slower with filter cropping, etc.

If I set the project settings to 1920x1080, I will get 29.97 fps even with filters, cropping, etc.

If I want to render 1080p with Hand Brake I will leave the settings alone. If I want to render to 4k, I can then change the project setting back.

All of my project videos are on an SSD but I can even do this with a WD Blue on USB3.

No need for proxies or intermediate files.

I am using the Nvidia 580 card.

What are your thoughts on this?

That is what I got on my system with the GTX580. The problem comes when you do a transition, like a crossfade of 1sec or 1/2sec.

With my R9 290 I can preview in 4K at Best/Full and apply Sony's own FXs, no BCC, and I still get 29.97fps preview.

Note that rendering is almost completely independent from preview/project settings. Even if you leave your project settings at 1080p you can still render to 4K and get actual 4K output. Vegas ignores project settings when rendering, with two minor caveats ...

1) Deinterlace method in project settings is used.

2) Any generated media you insert is done at the project settings resolution at the time the event is created. So, for example, if you add a title event while set at 1080p and then render to 4K, that title event will still be 1080p and upscaled rather than native 4K. I consider this a serious bug in Vegas*.

*A bug that does have some beneficial use though. If you're not happy with the smoothness of the fonts in text events you can always increase the resolution of them much higher and Vegas retains that setting even when it doesn't match the project resolution. Then upon rendering Vegas resizes to the output size and this usually results in sharper and smoother (yes, both) fonts than if they were at native resolution.

@OldSmoke

The problem for me is my budget is already screaming at me so I will have to stay with the GTX580 for now.

@VidMus

Nothing wrong with that. It's a card that is fully supported and in any case, working with proxies isn't that bad either.

What is the 4K codec and format you are testing?

More info on your system specs might help.

The max digital output on the 580 is 2560x1600, so how you are you seeing 4K output? Anything else will be doing a lot of scaling and what not.

Proxy editing might be your best solution on such low system specs.
