How do I render faster with a dual core CPU in VEGAS Pro 18?

Riscaper wrote on 3/10/2021, 1:22 AM

Hello. I have a problem with SVP 18. My videos (usually around 10 min) render in over an hour when nothing is running in the background. I tried everything that i cold find and nothing. Even got SVP 16 and that didn't help. I have a Pentium G4560 (dual core 3.5GHz) GTX 1060 3GB and 8GB DDR4 2666MgHz RAM. when I render my CPU is going 100% and RAM at 50% despite I let SVP use 6GB and my GPU is at 1% or 5% at most even though I use GPU render enabled. So how do i fix this issue?

There is no SVP, but there is VP 18.

The GPU is under the minimum spec for Vegas Pro (should be 4GB ram). Which render template are you using? Please share a screenshot. It is a NVENC one? If not it isn't using the GPU much for render.

Do you have many Fx in use? Some can be quite slow.

What do you mean by let VP use 6GB of ram? You didn't change the dynamic ram preview amount did you? That takes away from the ram the program can use. Try 200MB or 0MB.

Your overall ram amount is low which could slow down the process with caching. 16 or 32GB would be better.
For the GPU, I'd try upgrading to the NVIDIA Studio Driver.

Those are the templates that i use that have no difference. I do use some FX but for e few seconds. I did change the dynamic ram. But 0MB didn't help either.

There should be no need to use a floating point based project. Try using 8 bit instead.

but still it doesn't help much. On my laptop with intel HD graphics and Pentium N3700 2.4GHz (even tho 30fps) i was rendering in 40min max same kind of videos. (I was using VP 14)

@Riscaper There's too many variables to make a comparison like that- different hardware, versions of Vegas and video content.

For VP 18, try 8-bit full instead of 32-bit ACES.

Is your footage 60fps? If not use a 30fps project and render to 30fps.
Change resample to "disable resample" unless you are working with mixed frame rates and find it helpful. Otherwise it has a blurring effect.

For render mode go to MagixAVC, and select a NVENC one to use your video card.

I am using 60 fps but also since its a game it differs. also i record my facecam (not in this project) at 1080p 60. Also even though is NVENC my GPU is still under 10% use. And i think all the job goes to my CPU which cant handle that much.

The first 3 render templates were NVENC but not the fourth.

I think you are right that the GPU is waiting on the CPU- not much you can do about that. If you need better capture settings there's a guide in the forum FAQ to OBS.

i use Geforce Experience as a recorder. How will obs help me?

Try to use a recorder and settings that don't yield variable frame rate or otherwise hard to edit files. I have never used GeForce Experience but others doing similar videos use OBS with the above settings.

It records in constant 60fps

No OBS wont help you. your 2 core cpu is what Vegas was built around, and it performs well , 100% CPU, that's something rarely seen with modern CPU's of 8+ cores. As for GPU use, Vegas is not well GPU accelerated unless you're using GPU effects, but direct cutting with out effects not so much, although if you turn your GPU off in settings, you should notice a slower down in render and timeline performance, so it is doing something.

ok well what if i put a GPU effect on the timeline for a few seconds but at the bottom of the timeline will that speed up my render? Cuz really 1h+ even 1h 30min+ is way too much for a 10 min video thats not even heavily edited. Just some cuts, zooms, green screen (for just a few seconds(sub and like)), a bit of color grading and tiny motion tracking here and there.

You're likely seeing the problem of Vegas not handling NVENC encoding very well, Even if it's supposed to be Constant Frame RAte, there's a variability that Vegas doesn't like. It causes a general slow down. I"m making an assumption here that it's this 10mins of footage that is the problem, and another 10mins of non Geforce Experience NVENC'd footage you don't have a problem with and is rendered much faster. Your 100% cpu is not usual though, but you are using a 2 core cpu, so maybe that makes sense

With Vegas, the GPU doesn't really do much at all with just cuts and edits, your zoom, green screen, colour grading, motion tracking it does though. You could try transcoding your game footage to CPU encoded H264 to see if that speeds up vegas, but that by it'self is going to take a long time on a 2 core CPU, so ultimately may not help

Yea but that's the thing. after i record my gameplay i edit and render it separately so i just put my facecam in and start editing. The gameplay footage is already rendered. It takes less to render since i have just cuts and speed ups (the project at the top pictures is what it looks like).

Since every event on your timeline is timestreched and you also rendering to a different framerate than the framerate of your footage, setting the resample mode in your projectsettings to smart resample has an enormous slow down effect on rendering speed (besides the wrong setting of the pixel format to 32bit floating point).

Ok there we go. I rendered this video (just a test one) in 1080p 60 fps (even though the video itself is in 25) and it was done in 31sec. I did render the same video on my laptop and it was done in 1m 12sec with GPU (even though it doesn't have one (intel HD graphics)) usage of 15%-20%. And I rendered the same video in Adobe Premiere Pro 2020 and got it done in 53sec but Adobe didn't detect my GPU and I couldn't change to 60fps and was rendered in 25.

PC:

VP 18:(1080 60) 31sec render time. 91% CPU and 10-15% GPU usage as well as 90-95% RAM

AP 2020:(1080 25) 53sec render time. 100% CPU and 0% GPU usage 53% RAM

Laptop:

VP 18:(1080 60) 1min 12sec render time. 100% CPU 15-20% IGPU and 80% RAM

The simple answer is to run the program with the equipment specified in the minimum specifications.

That did not help me at all! PCs don't just rain. And now ure gonna say well dont use this program well ok what do u want me to use? FinalCut? DaVinchi Resolve? Adobe? I dont wanna switch and ditch the program that ive been using for 5 years now.

I think you should follow the suggestions 3Point and I gave you for improving performance and accept that the types of edits you are doing and media you are using with a slow CPU will limit the speed of your renders.

One other idea is to have Vegas send frames to Voukoder for rendering via NVIDIA or high quality CPU encoding (x264). It's often faster. Install the program and connector from here.

If I could suggest a next hardware upgrade it would be ram- 8GB is low these days.

You won't be using much of anything with that rig. If you can't afford the gear required to run the software, you shouldn't buy the software. This is true for all editing apps, none of which will run well on your system.

I find it very strange that you spend so much money to buy so expensive software for the rendering of GamePlays, but so stingy on the PC. ????????

You could try wondershare filmora, resolve likely no good for you, premiere possibly ok. But a lot of you game editors want access to many ofx plugins, which means filmora is no good for you, but it will likely be faster

Why do you assume that developers publish minimum specifications? Look up Occam's Razor and you will see why my answer not only answered your question but provided the best solution. Ignorance is no excuse especially when you try to hide it will surly answers.
