4k/1080p 120 FPS videos stuttering

Adr1ann wrote on 9/15/2023, 9:52 AM

Hello community, how are you? Firstly I want to apologize if my English is not that good!

I have the following configuration:

Processor: i5 10600k
RAM: 32GB DDR4
GPU: GTX 760 4GB GDDR5

When I start editing videos in 4k 60 fps or even 1080p 120 FPS as I edit and the project starts to have more effects and things like that, my Vegas starts to freeze a lot, the preview doesn't continue without crashes, and this happens even more strongly in 4k projects

How can I solve this, I thought about changing my GPU as it is very old, but would that really help? I would get an RTX 4060ti 8GB, some people said that the problem is actually my processor, can anyone clarify what the real problem could be? My goal is to be able to work more calmly and without these problems when editing because it is quite discouraging.

I usually use Vegas 14 or 16

Hi, can you try my solution? :)

Both your CPU and GPU (especially) are underpowered for the media resolution and frame rate. I just put a GTX 780ti in my old PC and at 4K 25fps the play back was 3 fps.

A more powerful GPU would help quite a bit but will be held back by a weak CPU. I would build a new PC.

Uma GPU mais poderosa ajudaria bastante, mas será prejudicada por uma falha de CPU. Eu construiria um novo PC.

Maybe an RTX 4060ti won't be used as well due to my processor, but it would help somehow, right? In the future I could upgrade the processor too... but at the moment I can't buy both together

The GPU isn't supported in newer versions of VEGAS (18+) and more and more is done with the GPU in modern versions. Your CPU is fine though you may be asking too much of it. My suggestion would be a new GPU (if you want new a 4060 is fine but you could get a faster 30XX GPU used for less money likely) and trial VP 21 and see if the combination is better for what you are doing.

I wouldn't edit in 120fps unless you have a real reason to. YouTube doesn't accept framerates over 60 and 120fps footage is mainly useful for slow motion.

If you want to see how your system compares you can try the benchmark in my system which will work for VP 16. Look at similar CPUs and you can get a sense of how framerate and render times would improve with a better GPU.

@Adr1ann When I was experimenting with shooting humming birds at 240fps, I found I could do it shooting hevc hd with a Zcam E2 camera recording to m.2 sata media via a cfast adapter. And then edit in vp18 without proxies on machines with Radeon VII/uhd630 or 5700xt/1660 gpus. If your camera and media can handle 8-bit Avc at high rates, that should be even easier to process. And, if your system has an igpu, vp16 should work just as well if Enable Qsv Encoding and Decoding is checked in General Prefs.

On lesser machines, like my Dell laptop at the time, I needed to make proxies manually and put them into their own folder. Then use the Vegas Swap Video Files function (in the Project Media screen right-click menu) to switch my custom proxy folder in for editing and out for rendering. Vegas internal proxies were much less effective, btw.
