Laging in preview-mode even with 4K Computer!

[Wayne Waag]

If preview performance is that important to you, then use a proxy. Vegas has an option to automatically create proxies for 4K source material. You could also use Vegasaur or just create your own using a format that previews well on your system.

Thank you Wayne Waag for your reply!

But I don’t know any of these methods.
I’m using the germany Vegas, maybe that’s why I don’t know these methods.
Can you try to explain me what “proxy/vegasaur” is?
Any advantages/disadvantages using them?

“just create your own using a format that previews well on your system.”
What do you mean?

[Wayne Waag]

A proxy is simply a copy of your original source material, but rendered at a lower resolution. For example, you can create an HD proxy (1920×1080) from your original 4K (3840×2160) files. Your computer can preview the HD proxy much better than the original 4K files. Once the proxy is created, you replace the original 4K file with the HD proxy file and do your editing. Once finished with editing, you simply replace the proxy file with the original 4K footage and do your render.

This can be done automatically inside of Vegas. From your project window, select your 4K files, right-click, and select Create Video Proxy. Once your proxy files are created, Vegas will use the proxy files if you preview using the Draft or Preview settings. If you use Good or Best, it will use the original material. For renders, it will use the original 4K material. The good thing about using the Vegas proxy builder is that it is all automatic.

Vegasaur is a script application for Vegas. https://vegasaur.com/ It is an extremely useful add-on that includes a proxy-builder. While Vegas is completely automatic, Vegasaur allows you to select whatever render template you want to use for your proxy. Of the two, my preference is to use Vegasaur because of its ability to allow you to choose the template you want. You can even create your own render template inside of Vegas and then use it when building proxies using Vegasaur.

By creating your own, I mean that you can render your 4K file to an intermediate that will preview well on your system, for example using one of the XDCAM EX templates. Once rendered, you can manually replace your 4K files with the XDCAM EX files and do your editing. Once editing is completed, you would manually replace the proxy files with the original 4K files. It’s the same principle, except that you do the changing from original to proxy by manually replacing the files inside of Vegas. Nothing is done automatically.

Hope this brief explanation will be of use to you. Perhaps someone who is currently using proxies for 4K projects will chime in with their recommendations.

Wow thanks so much!
I’ll try to do the proxy one.

But I still don’t understand why I have to lag with this build.
I noticed that my CPU almost reach 100%, while previewing a 1080P 60 FPS Video without any effects or other videos.

That is definitely not right. I have an old i7-3770K that’s overclocked a bit (4.2 Ghz) and a very weak video card (Nvidia 650) and it previews 1080 60P video on a second monitor at Best full without dropping frames with CPU at less than 50%. My suspicion is that your video card is not set up properly. I would check to see if the latest drivers are installed. Unfortunately, I’m no hardware expert. Hopefully, someone else can provided some assistance.

What codec and file format is your source footage?

What camera is it from?

What is your workflow? Meaning are you dropping camera original on the timeline and rendering to mp4 to upload to YouTube or something else?

What is your display destination for your edited material?

What codec are you rendering to for the final?

Have you used “AMD system monitor” or GPU-z to verify that the GPU is being used during timeline playback? Is the GPU enabled under preferences? Is your GPU running the latest AMD driver?

What are your current project settings?

Have you tried converting your UHD footage to XAVC-I.mxf, and not using LGOP format the camera likely shoots in?

For HD material, have you tried XDCAM-ex, or 422, or HDCAM-SR-Lite 60P, or Cineform.AVI?

System Things to check:

• Latest Video Driver from AMD
• Latest BIOS from motherboard manufacturer
• Latest Motherboard Chipset INF from Intel for your given chipset.
• Latest Network & Sound from chipset manufacturers
• All updates applied from MS, and non waiting to complete on system reboot

-MP4

-Go Pro Hero Black 4

Well I just put the 1080P 60 FPS file into the timeline and the preview-windows starts laging if I want to preview the video-file on “Best-Full”, even without any effects.

Have you used “AMD system monitor” or GPU-z to verify that the GPU is being used during timeline playback? Is the GPU enabled under preferences? Is your GPU running the latest AMD driver?
I don’t know why but I think that my CPU is the only thing that is running for the preview-mode.

And yes I think that I downloaded the latest driver for the GPU
I have chosen the “W8100” driver.

Are you running the latest version of Vegas, 4.53? There was a fix for GoPro footage on this release.

What are your current project settings?
A picture of it:

Your project settings are part of the problem. GoPro 1080 60P footage is progressive, not interlaced. Moreover, you are using NTSC settings. Presumably, you are in PAL land? In any case, make sure that your project settings are the same as your GoPro footage.

Well the temps look good during render, I do not see much of an issue there.

In Vegas, make sure your GPU is selected under Options>Preferences> Video> GPU acceleration. Restart Vegas if it was not selected.

You might try posting some images from GPU-z : https://www.techpowerup.com/downloads/2524/techpowerup-gpu-z-v0-8-5/

On the sensor tab of GPU-z, you can monitor GPU utilization during playback. Try this with a simple straight up file, and then one with Sony Min and Max filter applied. With Min/Max applied you should see some heavy GPU utilization.

One the 1st page of GPU-z if you roll over the “Bus Interface” field, you should get a popup that shows your GPU interface speed. This should read max speed.

An alternate is AMD System Monitor: https://support.amd.com/en-us/kb-articles/Pages/AMDSystemMonitor.aspx

This app provides a Task Manger like view of CPU+GPU utilization during playback.

I personally like Speccy – If you could post a .speccy file, that gives a lot more comprehensive view of the system config. File > Save Snapshot.
In Speccy – you can verify memory settings, Storage interface connection standards, Heat, see details on drivers loaded, and motherboard specifics.

If you are trying to create 1080-60P material, your project settings frame rate should be 1920×1080-59.94 Progressive. You can use the Match media Icon Button in the upper right corner to match your project to the source material.

There have been other posts on Hero 4 footage issues. For HD most like to convert the footage to Cinform.avi using the Hero app, then edit the resulting files. Converting to HDCAM-SR-Lite, or XDCAM-EX.MXF would be another Vegas optimized way of editing that content. Since the Vegas render profiles are dated, you will need to create your own 60P profiles by changing the Frame rate to 59.94.

For the 4K hero footage in Vegas, converting your footage to Sony XAVC-intra.mxf Same here for the render profiles and 59.94/60P if you do not have one that matches.

8-Bit mode vs 32-bit Video Levels in project settings – for smoothest playback stay in 8-bit mode. 32-bit video levels for converting 10-bit video formats to 10-bit capable codecs (HDCAM, Cineform, XAVC-I.) Also most believe you should color correct in 32-bit VL mode. However, if do not have a deep color / wide gamut monitor attached properly, your display is just previewing in 8-bit color mode.

The w8100 is 30-bit/10-bit video capable, but does require proper monitor and cabling. Obviously you will not see 10-bit video levels while previewing in 8-bit playback mode.

***Note on 60P material – most people posting render times are doing so for 24-30P material. Rendering 60i or 60P is rendering 2x the amount of frames so render times will need to be correlated to like for like. 2x the amount of time to render 2x the amount of frames is logical.
