Not fluid preview in Vegas Pro 18

LuluBent wrote on 11/6/2020, 5:11 AM

Hello to all,

I recently started using Vegas Pro 18.

When I add an effect of any kind (text, scroll credits, object tracking, etc.), the preview is not fluid. Or it's slow-motion playback.

But as long as no effect is added, the preview is completely normal and fluid.

I have Windows 10 Pro with AMD Ryzen 9, AMD Radeon Pro WX 5100 8 GB and 32 GB RAM.

Any explanation?

Thanks a lot!

@LuluBent  ... Bonjour et bienvenue au forum.

Maintenant en anglais ...

What media are you using on the timeline? Could you please provide a MediaInfo report on that media via:

https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

What settings do you have activated in Options/Preferences/Deprecated Features and File I/O?

Please also confirm that the VFX etc that you are using are Vegas Pro native VFX and not 3rd party VFX. If 3rd party, what are those 3rd party VFX?

Also, what are the project settings and the preview window setting (for the latter draft, preview, good or best)?

Also check in task manager that the GPU box video decode is showing some activity when trying to play back the timeline with preview set at Best auto.

Good evening

 

Obsolete features: no box checked.

 

VFX are indeed native to Vegas.

 

Preview window on best auto.

 

Without VFX :

 

CPU : 7%. GPU: 17%.

 

With VFX (object tracking + text) :

 

CPU: 7%.

GPU: irregular between 24 and 64% every two seconds.

looks like GPU working then, mine will sometimes start at 60% then settle at 20% or so.

Passmark rating your 5319 mine 17,645 so yours is no ball of fire. Your best option is to use proxy files? Your CPU will kill mine i5 3rd gen intel.

So my GPU is not powerful enough?

andyrpsmith wrote on 11/6/2020, 2:54 PM

I think it will struggle as mine will drop frames at Best Full with 4K and effects added.

Any and all timeline effects must render in realtime to be previewed; they are not files, just complex sets of instructions.

Therefore, added system and processor strain is the result. That's why there are two methods of Prerender available to you.

Try preview/full to prioritize playback smoothness.

You may need comparing Resolve or Premiere to Vegas Pro. 😂

@xcxz-a
As I understood LuluBent, he is looking for a solution for a smooth preview in Vegas Pro, and he is not looking for another NLE.

Good evening

Here is what I find:

I've added several titles and a thumbnail. Fluid preview. 

I add a scrolling credits on a transparent background right after. During this credits it is not fluid but once finished the video is fluid again. 

Adding an object tracking is not fluid during the whole video even if it only lasts a few seconds. 

Best regards.

RogerS wrote on 11/9/2020, 10:02 PM

These types of edits are quite processor intensive- it's not really unexpected. You are bringing preview down to preview/full or preview/auto?

Did you try using tracking with media while using proxy files?

Your GPU is a bit older and judging from scores, equivalent to an NVIDIA 1050. Good enough for 4K with minimal Fx applied but will struggle with intensive Fx.

Make sure you'd on the latest AMD Enterprise or other AMD Pro driver, and that Vegas is using it for decoding in preferences for preview and File I/O (should be enabled by default).

I have always used the Dynamic RAM preview for little complex projects and in order to almost instantly see in realtime the result . That is with GPU=OFF and lots of dynamic RAM dedicated . ( GPU=ON and lots of dynamic RAM = vegas pro has stopped working very soon , don't know why but it is just like that , unfortunately) . GPU is nice but one should not expect miracles ( even tried with the quadro P6000's series )

I leave the GPU on, but for max stability, on only enable large amounts of dynamic RAM when needed, and leave it low or 0 otherwise.

Hello

The preview is set to best auto.

Proxy files I don't know what they are. 

In I/O file it is AMD by default auto. 

Dynamic RAM is set to 200 MB by default.

I took into account the Vegas recommendations on their page: AMD Pro series with 8 GB and 32 bits. 

My GPU supports up to 5K on two displays.

It's not 3D editing either

Best regards

Right click on a media file to create an easier to playback "proxy" file. It improves performance.

GPUs do more than 3D- they decode media files and can process complex Fx. Yours is ~4 years old and has plenty of ram but not so much computing power.

Change best/auto to preview/full or preview/auto when your goal is smooth playback. Change to best/full when you stop playback to color correct or assess an individual frame.

andyrpsmith wrote on 11/10/2020, 7:50 AM

I do think Roger is right in that the use of proxy files will pretty much solve your lag problems. It's easy to do - just select create proxy files which are then used in the preview window by setting Preview - Full instead of Best full. Try it and see.

LuluBent wrote on 11/10/2020, 4:23 PM

Good evening 

I used the proxy as you said and indeed everything was normal and fluid by setting to full preview. 

I feel like it went from 60 fps to 24 fps. 

Concretely what happens if I send it
to YouTube? Will the result be the same as the original? I have nothing to do? 

You still maintain that the computing power of my GPU is insufficient? 

Best regards 
 

 

andyrpsmith wrote on 11/10/2020, 4:28 PM

rendering is the same as proxy files are not used during render only original full frame files. If you are happy to use proxy files then no need to upgrade your GPU but for the future.

So on YouTube it's the same rendering as the proxy files? In this case it doesn't suit me. It's not the rendering I'm used to having.

Which GPU to choose?

Sorry don't follow you? Rendered output is the same no matter if you use proxy files or not.
