vokouder r2.0 beta3 - GPU at 20% ( beta2 95/98%)

I tested I a few more things out and there is some other curious thing. If I change the preset value from nvenc to Slow or medium or fast there is a performance difference in Voukoder 1.2.0 (as it should be).

Slow = 275 fps average

Medium = 285 fps average

Fast = 300 fps average

But in Voukoder R2 all presets have pretty much the same encoding speed and fps values (it never goes over around 200 fps). There has to be something that is slowing down the encoding in voukoder r2.

As I can see your Render time is about 15 µs average.

Is it normal that this value goes sometimes up to over 5000 µs ?

You can see it in the logfile.

My Gtx 1080ti is reaching with your settings (gpu=0 preset=slow qp=15 rc=constqp) about 200 fps. I don`t think that a 2080ti is more than twice as fast. (my 1080p video has no effects or filters or something else and is located on a SSD raid 0)

Rendering is done on the CPU mostly. It also depends on your source pixel format and all effects and filters you have applied.

I have no filters and no effects in my test.

I also have no effects or something else applied. And I think a TR 1950X should have enough power.

Just to clarify:

Render: 15 µs <- Voukoder has no impact on this, it is entirely premiere

Process: 5 µs <- Voukoder has high impact on this

Encoding: 676 µs <- Voukoder has small impact on this. Mostly libav / FFmpeg

Can you look at my logfile above and tell me if the latencies are normal?

I am changing and debugging some things in the source code right now. Maybe I can find something.

Can you try Premiere CS6? I'm using it. CC 2019 seems to be slower.

I am using CC 2018, but I can install CS6. Testing it in a few minutes.

On my side CS6 is even slower than CC 2018 (around 170 fps but lower latencies).

Here are two screenshot from the Taskmanager (CC 2018 usage and CS6 usage) and the logfile which shows the latencies.

CS6 uses way more RAM than CC 2018 but the CPU and GPU usages are pretty low.

Voukoder 1.2.0 is also slower in Premiere CS6 (down to also 200 fps)

There are some issues with your system, yes. I have no clue why it is like that. It could be many things:

Maybe ...

• with AMD CPUs at all
• with Threadripper CPUs
• with high core counts
• with specific Premiere settings? Hardware decoding?
• ...

I did not get any hardware donations and I can't afford buying any test equipment. So I can just guess here.

But as you have a working Visual Studio IDE and the voukoder sources I'd recommend that you try to find the issue. Try to find that slow spot.

Try to profile it.

But the question is why Voukoder 1.2.0 is that much faster?

I am debugging right now, maybe I can find something.

What I can currently say is that the ffmpeg version doesn't matter, I tested it with both 4.0 and 4.1.

I found it. The problem is CUDA enabled in the Premiere Project settings. If I disable it (setting to software only), Voukoder R2 is exactly same as fast as Voukoder 1.2.0 (around 370 fps). Voukoder 1.2.0 doesn't care the CUDA setting in Premiere but in Voukoder R2 for some reason if its enabled the export is much slower.

Latencies are also normal with CUDA disabled:

[20:04:42] Video frame #574: Render: 38 µs, Process: 8 µs, Encoding: 2456 µs
[20:04:42] Video frame #575: Render: 77 µs, Process: 19 µs, Encoding: 2560 µs
[20:04:42] Video frame #576: Render: 79 µs, Process: 19 µs, Encoding: 2813 µs
[20:04:42] Video frame #577: Render: 47 µs, Process: 15 µs, Encoding: 2729 µs
[20:04:42] Video frame #578: Render: 84 µs, Process: 16 µs, Encoding: 2063 µs
[20:04:42] Video frame #579: Render: 58 µs, Process: 13 µs, Encoding: 1721 µs

But in CS6 this didn't work. In my case this doesn't matter because I am not using CS6.

So today i found the beutiful plugin, but upon reading the forums looks like my prefomance is not actually that good.

It looks like i have the same problem Vogelforscher had. When encoding using suggested settings(gpu=0 preset=slow qp=15 rc=constqp) i also get around 190 in AME and 200fps in premiere. Disabling CUDA does nothing, and disabling hardware decode makes premiere(or AME) unusable. Cpu usage peaks at 85, GPU around 50%.

I am using i7 8750H(6 core @3.9), 16 GB of Ram, GTX 1060(shouldn't matter, right?). Rendering and reading from my only SSD in the system(should not be the bottleneck).

my 6700k is 100% usage and gtx 1080 is only 50% is that normal?
