I have seen that the GPU acceleration does not work with my machine if I use the R9 390X. The reason seems to be that I have two GPUs in my machine - the other one is a Quadro K4200. If I select the K4200 for GPU acceleration, then it works here.

How much speedup do you see in the VEGAS LUT Filter with GPU acceleration enabled?

Took me some time to come back to that, since I wanted to run some comparision and tests.

I use a v-log UHD 25p 10bit file from my EVA1 (both Long-GOP but also All-I as the new Firmware was released today). Project Settings for editing are 8bit only. There is the Vegas LUT plugin on the file, with the Pansonic original LUT (v-log to rec709) only.

If I use in the GPU acceleration selection the R9 390X (that does not work on my system) I have something of 2 fps only. CPU utilization is about 70-80%, GPU usage is about 3 or 4% only.

If I select the nvidia Quadro K4200 I am backt to full 25 fps (preview best/full). GPU usage on my 8core System is abot 40%, and so is CPU utilization.

Comparision was done with best/full.

Ok, thanks for testing. I did more tests and now I'm seeing a significant speedup from the new GPU accelerated version of the VEGAS LUT Filter. I'm not sure why I couldn't get any speedup before.

The speedup depends on the preview resolution and on the combination of filters. I got a 12x speedup of the preview playback frame rate using a combination of filters that are all GPU accelerated, and a 6x speed up with a combination of filters that weren't all GPU accelerated.

GPU acceleration seems to make Vegas much less stable. I had several crashes during my testing.

By the way, the VEGAS LUT Filter from Vegas Pro 15 build 321 can be used in earlier versions of Vegas Pro, and the GPU acceleration works. Just copy "C:\Program Files\VEGAS\VEGAS Pro 15.0\OFX Video Plug-Ins\Vfx1.ofx.bundle" to "C:\Program Files\Common Files\OFX\Plugins\Vfx1.ofx.bundle".

Thanks for the tip! Got it working in VP13 & 14. No go in VP12. Means I can probably ditch the Vision Color LUT plugin.

Do you know or did you check if that 70-80% CPU & also it's efficiency (speed) of processing was about right for not using a GPU or would you say that cpu use is absolutely ridiculous and higher than not having a gpu?

That is one of the biggest problems i have with vegas15. If it won't use the GPU (when it should) the amount of cpu it uses is much too high to make any sense and the fps encoding is also much too slow. If you confirm that fault then it's something Vegas have to fix. The software should be able to detect something has gone wrong at minimum.

The comparison shows quite well that the utilization of the GPU reduces the CPU utilization (in that example from 70-80% down to 40%). So without the GPU Support the CPU utizilation is much higher, but even with a higher CPU utilization the result is not appropriate really - or how would you edit the footage with something about 2 fps only?

What can work for many effects it to reduce the preview quality - because here I have used best/full. But that will not be a solution for every Setting.

The question I ask is if 80% CPU on a system without GPU doing that render witgh 2fps is normal & to be expected or is that actually symptomatic of a fault. Are you able to go back & turn off all gpu's , using just CPU and see if that poor performance is what is expected for a non GPU system?

thankyou

Currently testing Vegas 15 before deciding whether or not to upgrade.... LUT filter seems to work pretty well. Much faster than the old Visioncolor plugin, which was unusable IMHO. In fact, if I export a LUT from FilmConvert, and playback through the LUT filter, it is much much faster than FilmConvert itself. Just FYI.

Using what GPU? FilmConvert has a great GPU Support, at least to my experience.

The workpoint with 80% CPU is where the System does not use the GPU acceleration really - so it is CPU only manly (GPU usage at 3-4% is no GPU acceleration at all).

Even one UHD stream with a LUT applied requires a lot of Performance, and if one wishes to edit UHD log footage with LUTs then the system should have enough performance. And here it means that a GPU seems to be necessary.

If you wish to run such a combination without a GPU - well, I am not sure if that works with any other NLE. Try that with Resolve, or Edius or the Catalyst. All will require a GPU as far as I know (especially Resolve).

So I am not sure what your point is.

Vegas built in LUT are much faster then Vision LUT. I can apply 4 LUT on GH5 10 bit footage UHD on the timeline and it play back best/full CPU only. CPU usage is 15% for 4 LUT applied. 1-2 LUT applied CPU usuage is 12-13%.. Vision LUT, I can not even get 1 LUT play back at best/full. Vegas LUT is a clear winner here. Computer is AMD 1950X at 4.0GHZ.

My GPU is an old AMD 290. Very good question though, because you reminded me that I did have an issue with FILMCONVERT GPU support last year, and now that I look at it again closely I don't think it is using the GPU on my system. Luckily the LUT filter does :)

Why when I add a lut to the "Lut Filter" any luts, it does not display? Every other plug in works included 3D plugins. What should I do ?

What do you mean "it does not display?" Here, I browse for a LUT file (e.g. GH5_cinelikeD_Fj100.cube) and the effects appear immediately.

As in the effect does not show at all , as if I didn't apply the effect at all but if I add brightness and contrast if shows the effect immediately.
