Killing computer but still slow preview
on Apr 7, 2014 at 3:58:19 pm

Hi,

I just bought a computer with killing config:

DUAL Xeon E5 2697v2
64GB of RAM ECC
GeFroce GTX Titan Black

I still can't preview my footage (with Sony GPU optimized video FX) in Full res and good quality !!

For example, just a blur between to videos can't be realtime preview !

It is fluid only when I put half res and draft !!

Is there something I missed ?

What we are missing is what IS your material and WHAT are your project settings.

I already give my material... But I can be more precise.

2 x 30" displays
Working on SSD
Sony Vegas Pro 12

My project settings are:
Full HD 1920*1080 24fps
progressive scan
Square
no rotation
Stereoscopic 3D: Off
Pixel format 8
Full-res rendering quality: Best
Motion blur type: Gaussian
Deinterlace: none

Do you need more information I could have forget ?

What is the MEDIA that you are editing?

[Philippe Gaudens] "I edit videos from CANON 5D markIII"

I don't have a 5D MkIII and probably not others. We need to know what the exact video format is. What does the MediaInfo utility say about those files. It is a free program you can download.

I do have a Canon 7D and they are MOV files with AVC video at 44Mbps, PCM audio for 1080p30. I can put a gaussian blur on one of these clips and it plays back fine GPU ON or OFF with one exception. Best Full, GPU OFF, in my half sized preview window which is a waste. Best Half/Auto is fine. I normally edit Preview Auto/Half.

Do you get different performance with GPU turned off?

[Philippe Gaudens] "GeFroce GTX Titan Black"
That's your problem right there. Vegas Pro 12.0 doesn't take full advantage of the new Kepler cards. So this card will perform, worse than a old 5 year old GTX 570. So while your machine may be killer... Vegas Pro can't take advantage of the GPU that you selected.

Thank you for you answer John, but I just got the Titan Black 2 weeks ago, and I had GTX 590 (dual GPU) before and it was the same problem...

Well, now, we're needing to look at the Quick Time Codec.

What Version are you running?

Can you PLAY the file in a QT Player?

[Graham Bernard] "Well, now, we're needing to look at the Quick Time Codec."

Vegas bypasses quicktime for MOV files with AVC video and PCM/AAC audio. They publicly state this on their website, aka native support for..., and I can load my DSLR file without Quicktime installed.

You can tell if Vegas is using QT by looking at the file I/O plug-in Vegas will use to read the file. From the project media window, right click, select properties, then go to the general tab and scroll to the bottom.

For the DSLR file it should be using compoundplug, it it is using QT it will be qt7plug.

Thanks Norman - I'll never understand this, even when it says:-

"Format : MPEG-4
Format profile : QuickTime
Codec ID : qt
"

Yes, that is what MediaInfo says about a Quicktime file.
A little further down in MediaInfo we see this for DSLRs/digicams
Video
ID : 1
Format : AVC
Format/Info : Advanced Video Codec

The only items I know for sure Vegas bypasses Quicktime when given a QT MOV file is when the video is AVC and the audio is PCM. My Canon 7D DSLR, Canon digicam(s) and a downloaded GH3 file all confirm this.

In Vegas for Canon 7D and Panasonic GH3 files in the media properties, general tab, Vegas says...

Plug-In
Name: compoundplug.dll
Folder: C:\Program Files\Sony\Vegas Pro 12.0\FileIO Plug-Ins\compoundplug
Format: Sony AVC
Version: Version 12.0 (Build 770) 64-bit
Company: Sony Creative Software Inc.

With I load a Quicktime ProRes file I get
Name: qt7plug.dll
Folder: C:\Program Files\Sony\Vegas Pro 12.0\FileIO Plug-Ins\qt7plug
Format: QuickTime 7
Version: Version 12.0 (Build 770)
Company: Sony Creative Software Inc.

Quicktime is a PITA so it makes sense to bypass it for the most common formats, which Vegas already has internal support like AVC. Just about every DSLR and digicam out there tends to output MOV files with AVC video.

Vegas Pro doesn't support dual GPU either.

Can you post a small sample video file in this format to the COW? I'd be happy to test playback with my ATI Radeon HD 5870 and see how it performs. Maybe it's just a difficult file format to decode?

Hello,

I'll try to share a 5DIII video.

I want to specify that playing back a 5DIII is not the problem. My problem is when I have FXs like blur transition (GPU optimized) or when I have a text event with moving shadow (also GPU optimized), it can't play flawlessly at 30fps, it goes down to 5-6fps until the FX or the moving text is finished... Then it plays normally on a part of the footage with no FX.

With my dual-GPU card, I was able to select only one of the two GPUs, as it was two different cards.

With GPUMonitor, I can see that playback and FX calculation is handled by the GPU, but not really fluid.

This is totally normal and expected. If you want to preview these transitions at full frame rate, use Ram Preview (Shift+B) to temporarily built a RAM preview of these FX. You can also use the Selectively Prerender Video (Shift+M) option to keep these renders around. Like I said, my ATI Radeon HD 5870 plays these back at full frame rate on the Sony "Red Car" demo while my NVIDIA Quadro 4000 cannot. The ATI Radeon cards seem to be better at timeline playback than NVIDIA cards.

If you want to create a small project with one small piece of source video from your camera and some transitions and upload it to DropBox or something, I'd be happy to down it and test it on my systems and see what frame rates I get.
[Philippe Gaudens] "With my dual-GPU card, I was able to select only one of the two GPUs, as it was two different cards."
Like I said, Vegas Pro does not support dual GPU's.
[Philippe Gaudens] "With GPUMonitor, I can see that playback and FX calculation is handled by the GPU, but not really fluid."
This is a mystery to everyone. I am very unhappy with Vegas Pro's inability to leverage my hardware both CPU and GPU. I've had stuttering playback where Vegas is using 25% of my CPU and 40% of my GPU and sat their and wondered why I bought such a powerful computer if Vegas isn't going to take advantage of ALL of it. So far, there is no answer. :(

I cannot find any 5D mkiii 1080 All-I video to download and test on my machine.

I can render an XAVC Intra 1080p30 file and that plays fine with a gaussian blur effect on Best Auto.

This file is very close to the 5D specs, but of course not exact.
114Mbps (a fair bit higher than 5D), CABAC=No, All-I, 1080p, 29.97.
