Currently eAC3 is not available in Voukoder.

Maybe I can add it, if its handled like AC3 in the source code?

I encoded it with StaxRip which uses NVEnc by rigaya with this parameters I think:

--vbrhq 10000 --codec h265 --preset quality --profile main10 --tier high --output-depth 10 --weightp --max-bitrate 10000 --aq --aq-temporal --cuda-schedule spin --videoformat ntsc --colormatrix bt2020nc --colorprim bt2020 --transfer smpte2084 --cabac

In the new NVEnc version you can also set this parameter:

--dhdr10-info <string> [HEVC only]
Apply HDR10+ dynamic metadata from specified json file. Requires hdr10plus_gen.exe module additionally.

Oh nvm. you can encode HDR conform. I found a 4K Video file which I encoded a few months ago with NVEnc.

You can encode 10 Bit but I don't think that NVEnc can encode HDR conform.

Vouk you are right. When using 60fps level 4.1 is to low.

The parameters you have choose should work. Can you please append the complete Voukoder Logfile?

In Voukoder Version 2.0.7 when using fdk-aac there is an error message if you open a saved profile with fdk-aac. I also deleted all saved profiles but if I select fdk-aac in the Audio Settings the error message appears too and Premiere crashes.

Maybe disabling the iGPU could improve performance. On my old system this helped.

I think it has something to do with nvenc look here

Logfile still exists under Voukoder Settings Tab. You're right, overclocking could cause this crash.

B-Frames with nvenc_hevc are only supported with 2000 series cards I think. Look here

Ok I tested it and I can reproduce that problem when using color range full (0-255), with limited color range it works.

[17:48:24] Opening codec: hevc_nvenc with options: b=10000000,gpu=0,preset=slow,rc=vbr
[17:48:24] Opening codec: aac with options: b=96000,profile=aac_low
[17:48:24] Requesting pixel format: p010le

[17:48:24] Closing encoders ...

Currently I think it is not possible to export audio in multiple tracks, only one audio track is created every time.

If I have two or more audio tracks in my project, is it possible to split these in multiple tracks when exporting and not only one for all?

I installed Windows 7 to test this issue but I can't reproduce it with Premiere CC 2018. Maybe this only appears with older versions of Premiere under Windows 7 ?

These dlls are from Internet Explorer but I don't know if this has something to do with the crash. Maybe you can try to enable/disable Internet Explorer in Windows 7 and testing again.

Log file is in the Voukoder Window under Settings->Logfile

AMD Threadripper Encoding Guide

General settings to improve encoding speed

• Ensure that you have the newest drivers installed for your GPU, CPU and Chipset
• Set Memory Access Mode to Distributed in Ryzen Master (UMA)
• For new generation Threadrippers disabling Dynamic Local Mode in Ryzen Master could improve encoding speed
• For high performance CPU's with many cores like AMD Threadrippers or Intel Xeons there is a high chance that disabling CUDA in Premiere/Media Encoder speeds up the process, except if you have a lot of effects applied which can be rendered by the GPU (also if you export in x264 or x265)
• Ensure that your maximum CPU power is set to 100% in the Windows-Powerplan
• Ensure that Premiere/Media Encoder has much RAM as possible
• I recommend to use a SSD, especially for large video files or exports

Encoder specific settings

VP8/VP9

• Disable a few cores in Ryzen Master (VP8 and VP9 using only a few cores)
• To reach faster encoding times then, you can clock the other cores higher

Sample encoding times with a Threadripper 1950X

Environment:

• Windows 10 1803
• Adobe Premiere CC 2018 12.1 (CUDA disabled)
• Voukoder R2 2.0.5
• AMD Threadripper 1950X @3.7 Ghz (Memory Mode Distributed, all cores enabled)
• 32 Gig RAM (Quad Channel)
• Geforce GTX 1080 Ti

NVENC H.264

x264

Is your export slow?

Check the Taskmanager while exporting and look for CPU, GPU and RAM usage.

• Is your CPU/GPU load only at a few percent?

When using nvenc check the FPS while exporting

• Type this in a command line window: "c:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" encodersessions

After exporting check the Voukoder log and look at the render times (first ones in the log)

• If you have very high values like 20000 µs all the time there could be something wrong (some peaks are normal) or CUDA is enabled and the GPU is not used
• If you have a lot of effects applied the render times can be very high too, but this is normal

If you think that your export is too slow and some of these points apply, check the forum for existing topics or create a new one and explain exactly as you can.

Mhh.. in Version 2 of Voukoder playing 2pass video files in VLC and Plex are working now.

Zitat von Digeridoo

Preset slower already includes: rc-lookahead=60, b-adapt=2, direct=auto, trellis=2. You do not need these options. bframes=3 is default for x264 - it also can be omitted. Setting ref to 5 you should increase level to 5.0, because level 4.2 for 1080p allow only 4 ref frames. This is about hardware compatibility.

All these about knowledge what these options are doing...

I set rc-lookahead=60, b-adapt=2, direct=auto, trellis=2 because in the Voukoder UI these settings didn't change when selecting preset slower. I have never said that I want hardware compatibility with these settings and level will be set automatic by x264

Pretty much every new device can play videos with that level.

I have good settings for x264.

These settings provide the best possible quality in my eyes with x264 without wasting CPU usage.

Bitrate is set for 1080p 30fps in this case.
Encoding with this settings take a while

Enable 2pass!

b=4000000 preset=slower profile=high rc=abr tune=film x264-params=aq-mode=2:rc-lookahead=60:bframes=3:b-adapt=2:b-pyramid=2:ref=5:direct=auto:direct-8x8=1:me=esa:merange=24:subme=10:trellis=2:no-dct-decimate=1:no-fast-pskip=1

I recommend to go a bit higher with the bitrate if your video has 60 FPS or if it's recorded gameplay.
