AcePro 2 with Vegas Pro 19

Douglass-Ray wrote on 3/28/2025, 3:38 PM

I’m shooting with my AcePro 2 in 8K/30 fps, and editing with Vegas Pro 19. When placing any 8K clip on the timeline (e.g. a six-second clip), playing the clip in Vegas – even before adding effects – is extremely jerky. The Vegas settings are:

(1) Template set to 7680 x 4320

(2) Frame rate: 29.970

(3) Motion Blur: Gaussian

(4) Deinterlace: Blend Fields

(5) Resample: Disabled

Also, when opening many of my AcePro clips with Windows Media Player, there’s often a @5-second delay before the clip plays – many are similarly jerky.

In the past I’ve always edited 1920 x 1080 clips at 60 fps, and have never had any problem.

Is it possible that my CPU isn’t powerful enough for AcePro at 8K? My CPU is 7th generation Intel (i7-7700K CPU @ 4.20 GHz).

Thanks for any help.

@Douglass-Ray Hi, in a previous post you wrote this -

Vegas 19, updated 7-5-24; Build 651

Windows 10 Pro

CPU: Intel i7-7700K CPU @ 4.20 GHz

RAM: 32 GB

Motherboard: MAXIMUS IX HERO; BaseBoard Version: Rev 1.xx

Graphics Card: - Radeon RX580 8 GB 2048 SP

Sound: VA2246 Series-0 (NVIDIA)

If this is correct can you put it in your Signature by clicking your icon at the top of this page My Profile, this will then always show at the bottom o your comments.

8k is four times the resolution or to put it another way 16x bigger than 1920x1080 so it is going to be harder to use, I suspect proxies will be the way to go for you but I'd quite happily be educated on that as I don't often need proxies with my pc. 🤷‍♂️

The info of the media would be needed so ,

There's an App called MediaInfo, download it, it's free & a fast download with no added adverts or any of that rubbish https://mediaarea.net/en/MediaInfo.
After downloading, right click on the media file in your Windows folder, open MediaInfo, choose Text from the options at the top, drag the edges of the window that pops up so it shows all the information & screen capture that page, post that image on here using the arrow button next to the smiley at the top of a new comment 👍

Or Copy & paste the information in a new comment like this -

Thanks! I see that using a proxy would work, using the software to create a temporary manageable version of the 8K file, then applying the edits to the original, large file. Alternatively, how powerful would a PC have to be to smoothly handle 8K in Vegas? (Prohibitively expensive?)

You advice is appreciated.

You would need a very powerful computer to edit 8K natively. That equates to "expensive". Considering your CPU is 8 generations behind the current Intel, or you GPU is 5 generations behind AMD's latest, editing 1080 is ok with your current build. As @Gid aptly explained, when you edit 8K, that is 16x greater resolution than 1080HD. Think about that. And think about how much the hardware will cost to be able to work with those files. We are not talking about mid-range computers.

Working with proxies, you do what you want to them, and when it comes to rendering at the end, the original footage will be used.

@Douglass-Ray Sorry I can't advise on what PC to buy, that's mainly because I agree 'expensive' but I don't have experience using 8K on a lesser machine so how expensive I wouldn't know. No brag intended but when I bought mine the motherboard cost around £1,049.99, CPU £2,367, GPU around £2k, RAM about £1k (those prices are new to buy today but the prices haven't changed much since I bought my PC.) Total system build price inc Windows £8,760. (you can get all these cheaper from Ebay but.. would they be ok .. how long would they last.. )

So others would have to answer that, but if you can buy what you can afford then using proxies would be the way to go, as @Reyfox says there's no need to 'apply the edits to the original'. that's done for you when it comes to render.

PS, I often find it's the software as much as the hardware that makes a difference in performance, I'd suggest you invest in the latest Vegas Pro 22 which has come a long way since Vegas Pro 19.

Thank you for giving me a quick education in the real world of high-end editing! That's definitely out of my range for my website and YouTube publishing. I'll go the proxy route for 8K files and any others Vegas Pro can't easily handle. Thanks for taking time to get me on track.
