Ut Video

For your video it's 420 BT.709

Preset - slower, profile - high, CRF - 17, GOP - 75 (for normal seeking afterwards):) It's heavily slow on noise scenes (especially on RGB input from colored BMC videos) and just a little slow on normal scenes. I know, I know, I need at least Ryzen 8/16, but well - right now I just can't afford it and using my old Sandy Bridge i7, clocked to 4.4. It's not super fast, but for 10 years old processor it rocks:)

Try UTVideo, maybe it'll be smaller:)

Oh, really? I use it only for output of draft cuts, and for that purpose it's the best solution. Fast with ok quality - what else?:) And for final output I use x264 of course, it's way better than H264 native output in Premiere, but slooooow...:)

Yeah, I think it's the same problem as here

Strange problem with parsing list of encoders with new ffmpeg on some pcs. Vouk is working on it, as I can see, last version for tests is 6.2rc3

Quote from Vouk

Yes, 6.1rc2 is actually the latest version. I renamed the first 6.1 to 6.1rc1 after still haing issues there. Sorry for the confusion.

It happens, don't bother:) 6.1rc2 works fine on my PC, W7, GF760, Intel i7

Quote from Vouk

The issue with NVENC not being available has been fixed in 6.1rc2.

Did you try version 6.1rc2?

I have NVENC in 6.1 release, everything is fine. I didn't try 6.1rc2, I installed 6.1 (from your post here) without release candidates. Here I'm trying to help, because you know... I think I'm smart, I'm from IT departament and as they say "Two heads are better than one":) If I'm completely wrong (with voukoder 6.1 hangs on h264_amf, ffmpeg glitch with AMD hardware encoder) and messing with your work I can shut my mouth and only read with curiosity:)

P.S. I've just tried 6.1rc2 - NVENC and other encoders are visible and working like a charm, in CC2018 and VirtualDub:)

So for now I think maybe you can move h264_amf to the end of the check-list (so it'll be last for checking) and see if it helps:)

Quote from Vouk

The strange thing is this error (that the list of encoders is empty) just occurs to a few users only. Looks like the data from the resources files is missing after the initialization.

Yeah, I've tested my CC2018 like an 100 times, everything is fine. I was trying to reproduce it, tried BT.601, limited and full range, different aspect ratios - nothing happend, everything is working. And in voukoder_h's logs I've found this:

version 6.0

version 6.1

So I decided it's some strange problem with ffmpeg and hardware detection, which hangs on h264_amf. And again - without GUI, on preset, it's working! voukoder_h didn't mention that, but he was able to export with version 6.1, probably using preset in media encoder. Some strange things:)

Yeah, I'm bored, so I don't know why, but I examined your logs. You forgot to say, that you were able to successfully export with NVENC for two times in a row with 6.1 version, and I assume you were using previously created preset? So with preset (and without calling voukoder's GUI) export is working? Then I found out you connect one monitor to internal videocard (intel) and another to external videocard (nvidia), so you have notebook? Can you try to use voukoder without second monitor? And voukoder hangs when loading (and not unloading) h264_amf, which is AMD hardware encoder. It's really, really strange and I presume maybe, just maybe you were using this version of windows with AMD videocard? And then changed notebook and kept windows? Theese are all IMHOs and maybe I'm digging completely in wrong direction, but!..

Quote from Vouk

Does this version solve the issues?

https://www.voukoder.org/_download/voukoder-6.1g.msi

?

Kleinrotti want's to run 6.1 in the Debugger with an old Kepler GPU. Hopefully we finds something. Otherwiese I'll buy an old GPU on ebay.

Yes, it finds NVENC! Excellent:) Log attached.

Quote from Vouk

ArnoldK Super und danke!

tyf Can you confirm this version https://github.com/Vouk/voukoder/…oukoder-6.1.msi is working again?

Yes, now it works! New 6.1 version now sees old Nvidia cards! Thanks, Vouk, good job! Attaching log.

Quote from Vouk

Next round.

https://www.voukoder.org/_download/voukoder-6.1f.msi

Fail again, no NVENC in the list. Log attached. Let the battle continue:)

P.S. I somehow think maybe we can keep something like in 6.1c version? All encoders are visible and let user decide, which one to use:) But then there will be a lot of crashes, posts on forum like 'I have nvidia with ryzen, why I can't use AMD AMF and Intel QSV?' etc:)) So I don't know really...

Quote from Vouk

Unfortunately I had a typo in the code that made all encoders appear. *sigh*

But it seems log3.txt showed the error:

Code

[19:39:31] FFmpeg: Lossless encoding not supported

When testing the encoders for availability it uses a default setting that wants to encode in a lossless mode. This is not supported with the old GPUs and that's why it fails. Seems it was introduced with FFmpeg 4.3.

Working on it.

I've ran a few tests with version 6.1c (which shows all encoders), if you select Preset - lossless, Virtualdub crashes, Voukoder shows error. If you select QP=0, everything is fine, but it doesn't seem to be lossless, like with CRF 0 in x264:))

Sorry, I was away from my computer.

So, 6.1e also don't working, no NVENC in the list. Log attached

Quote from ArnoldK

Ich verwende vorerst 6.1c da ist der Teufel weg!

It's working, but shows every hardware encoder available, without detection:)

It's the same again, 6.1d doesn't show NVENC in the list. Attached log.

Quote from Vouk

Do you mean NVENC basically works when using an existing preset, but the encoders are just not listed?

Maybe somebody else can test this, too

1. Create an NVENC profile/preset with Voukoder 5
2. Update to Voukoder 6 (NVENC is not available)
3. Load the NVENC profile/preset and try to export with it

Yeah, as I said before, you can export with NVENC, using previously created media encoder profiles. It's just you can't see NVENC in the list, but you can export with it.

Quote from Vouk

Please try this:

1. Make sure low level logging is enabled
   
2. Download and install this: https://www.voukoder.org/_download/voukoder-6.1c.msi
3. Start up your app and check if the encoders appear or not (it's okay if they don't appear)
4. Open the explorer and go to %LOCALAPPDATA%\Voukoder\Logs
5. Open the log file with todays date and copy it to the forum / send it to me.
   This file should contain the reason why an encoder could not be loaded

Sorry, that it's so complicated but unfortunately I don't have such video card.

Oh, well, let's do it!

Installed 6.1c - check.

VirtualDub 1.10 with voukoder. I can see all hardware codecs, like AMD (I have Intel) and QSV (I have old intel 2600k without QSV). And NVENC also visible. Attached screenshot.

First attempt to export video - alert window "error in Voukoder", failed. Attached log1.txt

Second attempt to export - success! Attached log2.txt

Third attempt - success! Attached log3.txt

So, 2 of 3, it's working somehow:)

Quote from Kleinrotti

Maybe some old saved profiles of Voukoder cause this? Can you try to delete all saved profiles in Premiere/Media Encoder?

It's really not about profiles in Adobe, I was testing it in VirtualDub, it's the same.

Quote from Vouk

Is it fixed in this version again?

https://www.voukoder.org/_download/voukoder-6.1.msi

Quote from Vouk

What about this one? Built with SDK 9.0. This should work with GPUs down to Kepler.

https://www.voukoder.org/_download/voukoder-6.1b.msi

Both are not working, sad... And thanks for all your great work! By the way I wish to thank you for VirtualDub with Voukoder, with ffmpeg import and vobsub plugin for subtitles it become ultimate solution for encoding practically everything! Thanks!

Nah, it's useless, after all reboots and reinstallations voukoder 6 simply doesn't see NVENC.

BUT! If I select previously created profile with NVENC in media encoder, it encodes just fine!

So it's probably detection error in Voukoder itself.

Thanks for answering! I've ran another test, with ffmpeg 4.3.1. Here is my command

ffmpeg -i "DSCF6533.MOV" -c:v h264_nvenc -preset hq -profile high -cq 20 "DSCF6533.mp4"

Everything is fine, ffmpeg 4.3.1 sees NVENC and encoding.

P.S. GF 760 is still supported, here is the link

https://developer.nvidia.com/video-encode-d…-support-matrix

On the bottom there is green button, to see all supported Geforce videocards:)

I'm ready to provide more logs, like internal ffmpeg logs, if there are any:)

I'll try to reinstall drivers and voukoder this way:

• uninstall Voukoder and connectors
• uninstall nvidia drivers
• reboot
• install nvidia drivers
• reboot
• install Voukoder and connectors

I'll write here results.
