When im rendering video my GPU not working just 1% and CPU 100%

Latest setup

This adds NVENC (NVIDIA) encoding and seems to be working fine with higher GPU usage and lower CPU usage. I'd still change hardware decoding to Intel QSV for stability in VEGAS.

Dynamic ram at 50% is still very high.

Do you actually have an Intel CPU and iGPU with QSV? Your screenshot doesn't show one. Here's my system:

If you don't actually have QSV then you can't render with it, even if it's an option. If you do have it make sure it's enabled in bios and install a recent Intel display driver for it. I use this free tool from Intel to keep my drives up to date: https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html

I have got this CPU without Intel UHD Graphics

Dynamic ram I changed to 5% like you said

[Edit, I see you said WITHOUT Intel graphics. I thought earlier the post said it had it]

Great, now you need to go into your BIOS (UEFI) and enable the Intel UHD graphics as I don't see it listed in task manager/performance. I have a 13th generation i5-13600K and the iGPU works GREAT in VEGAS.

Just looked up the CPU: I don't see any mention of Integrated graphics: https://ark.intel.com/content/www/us/en/ark/products/134587/intel-core-i512400f-processor-18m-cache-up-to-4-40-ghz.html

You are sure it has it?

Your render with NVIDIA looks fine, it's just that for decoding media there are benefits to using the Intel iGPU in VEGAS if it exists. If it doesn't exist use NVDEC.

I tried 4k render and final video chopping too render time 4minutes I tried same video in Capcut render time 8secs GPU doing great job

My CPU 12400 (F) = without iUHD

i5-13600k 38k Benchmark that's nice maaaan :)

Maybe you have to dive into the BIOS to make your iGPU (Processor Graphics-Intel® UHD Graphics 770) available

How can I make iGPU ? My PC has just NVIDIA GeForce RTX 4060

here is link https://www.uschovna.cz/sk/zasilka/MZVSM93VA5KH79TE-RPZ where you can see my chopping video i add just 15secs

Okay, so definitely no iGPU (didn't think F had it, K do).

VEGAS isn't Capcut- it can do much more sophisticated edits but the architecture doesn't make the most of GPUs (yet).

Did you ever write exactly what the footage was? I can't find it. There's no GPU decoding here in VEGAS but is in Capcut ("video decode" in task manager/performance). If it's HEVC, try unchecking legacy HEVC in preferences/ file io and see if performance improves. VEGAS can't encode a file any faster than it can encode it, and here the program is waiting on the CPU to get decoding done it seems.

Feel free to try render benchmarks from my signature as well- see how your times compare to similar systems.

I don't know what I'm looking at with this video- I see some mild flicker. My player is dropping frames though (6 year old laptop).

Is the source (original) file variable framerate? Do the framerates perfectly match between the source footage, project and render settings?

I tried to render 17min 4k video with

PC after 20min 2% done remaining 9hours

Samsung S23Ultra with CapCut after 15mins finished 4k video 10GB size

Capcut will automatically use hardware encoding, with Vegas you need to select a MagixAVC/HEVC Nvenc option, Nvenc being the Nvidia hardware encoder

(8K source 8K output)

(8K source 4K output)

Please can you do print screen where can I find it MagixAVC/HEVC Nvenc option thx a lot

This is mostly useless. Try MediaInfo again. https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

It says 30fps but is it constant framerate? MediaInfo can tell you.

Your project says 30fps.

Is your render also 30fps?

The file you uploaded was 29.970 FPS which is not 30.

You should match your encoding fps with your source and timeline fps. So 30fps source, 30fps timeline, 30fps encode. I believe you have to manually type 30 into the encoding template, as Vegas only has 29.975fps option. However I don't think that accounts for the dropped frames (choppiness) seen with your encode.

Vegas handles phone videos very poorly, it can't see all the video frames, while editors like Resolve and Capcut and transcoders like Shutter Encoder and handbrake can handle phone videos much better. That means you either use another editor or you transcode all your phone footage. Capcut is a 4K editor so if you want 8K you'll have to use Vegas.

Also to confuse things, I have the same S23U phone, and also use the high bitrate encode option that encodes to HEVC. It does sometimes drop frames but not as bad as the video you uploaded. You're making a comparison between Capcut encode and Vegas encode and find Vegas encode choppy while Capcut is smooth, so that's a Vegas problem . They need to fix the editor.

Hello Todd-A0 yesterday RogerS told me same thing about 30fps vs 29fps so I tried already to change me setup to 30fps and there is not different. Final video with similar copping effect :( Yes I'd like to play more about 8K so I have got option Sony Vegas (copping video), Adobe Premiere Pro(no experience yet), Final Cut (for Apple) and DaVinci (offline media ) no support . Did you say your videos are not as bad as the video you uploaded. What's your version of SV please and what about setup can I change something ? Maybe I have got problem with my GPU Geforce RTX 4060 how looks your GPU performance(encode,decode) during rendering . Any chance to see how looks your 8K video after render ?

peter-d5816 wrote on 10/8/2023, 6:40 AM

I tried to render 4k30fps and there is copping effect too during whole video :(

peter-d5816 wrote on 10/13/2023, 2:39 PM

So I have got only last chance with Adobe premiere pro ?

RogerS wrote on 10/13/2023, 3:01 PM

Your render and project settings look good for 30fps media.

If VEGAS doesn't decode this footage well you could convert it and then "swap video files" (right-click on media in VEGAS). https://www.shutterencoder.com/

If the problem is at the render stage another option is to encode through Voukoder. voukoder.org/

Both options are free so worth a try?
