The first one was started with 23.98 fps. The other 3 ones with 59.94. Voukoder uses the framerate you have set in your NLE. Can you double check it's really set to 23.98 fps in DVR?

This is most likely not a Voukoder issue.

auluswang You might try 0.7.2.1. I'm setting color space, etc there.

What framerate did you select in your NLE? Can you share your voukoder logfile? (See the sticky post in this thread.)

I'm checking this ...

It's available in the downloads section now.

I found a bug: the latest 13 or 12.1, in Davinci studio 18.5beta or 18.5, the data level (Auto, Video, Full) is missing. However, in Studio 18.1.4, it is ok.

Same thing for me. Im using 13.1 Voukoder with the latest connector.

Can you try updating DVR to 18.5.1 build 6 (Latest version) and see if this is fixed? I don't have control over that setting. DVR decides if it shows it or not.

I have tried to reproduce it, but in my case it works:

Can you provide an example clip with steps on how to reproduce it?

1. VoukoderPro created mov file, during checking by MediaInfo app, the mov files cannot show 'color range' and so on parameters, any plan to add the showing function to VoukodePro ?

If I just could remember why I removed these lines from the code ... AFAIK there was an issue with HDR export ...

Need to check this.

2. During the similar "bit rate" level compare DRS (18.5.1) created mov file with VoukoderPro (0.7.1.11) created mov file, during playing from image quality perspective, DRS created is visiablely better than VoukoderPro's.

I strongly suggest to avoid bitrate based encoding until it is absolutely neccessary. It's better to use quantizer parameter based strategies. The Voukoder presets are complex and quite more than just the bitrate.

Yes, I need to bring that into VoukoderPro ...

Sure. will do.

Made another fix regarding the filesize / compression. There was in fact an issue some settings were not applied.

I used your scene to export the file which was playable with MPC HC, MPC BE and VLC.

Can you provide an example DVR project I can use to investigate the crashes?

You can try to holding SHIFT-CTRL during startup and clear the plugin cache.

I have checked (and fixed) this.

"Main 10" requires "YUV 420 (10 bit)" to be set. I have added this option to the format dropdown.

Can you test if the build below fixes this for you?

I am using DVRS 18.5 and the data level control is visible to me. I also have no control whether it is visible or not. That's in DVRS' control.

By the way, I hope the voukoder can establish a Linux release. Linux can use the Nvidia 12bit 4:4:4 h265 8K hardware decoding, while windows only 10bit 420.

VoukoderPro is designed to be working on Windows, MacOs and Linux. Once it is working on Windows i'll work on the other builds.

Zitat von Abd

in voukoder pro, the lack of x265 an x264 is a pity, while nvenc 4:4:4, no matter how I choose 12bit or 10bit, it can just be 8bit. that's a problem.

Yes. I'm working on that.

Do you mean this one?

Yes, I might add that.

Edit: Added it to VoukoderPro.

Fixed the issue.

Before you test the fixed version you need to change that -2013260544 value in the scenes.json file to either true or false.

Does it help if you delete your scene.json file in C:\Users\(username)\AppData\Local\VoukoderPro ?

Found out what the issue is. FFmpeg expects a number of bits/s. I need to multiply the input by 1000 somewhere. Not sure where i should to this in the code yet.

Edit: Should be fixed now.

NVENC VBR

• 20 kbit/s min, 2000 kbit/s max:
  Bit rate mode : Variable
  Bit rate : 24.4 kb/s
  Maximum bit rate : 1 984 b/s
  
  The thing is: If the source is a very simple source (like a plain low res test chart or plain color frame that is not changing) it doesn't even need that 2500 kbit/s. Actually you want the get the lowest bitrate needed for your video. Especially when using VBR.

• There was a bug. Fixed it, thanks.

Hangs if in different folders

• Can you describe this in more details. I was not able to reproduce it.

Multiple file outputs

• I added a check for duplicate filenames. The export aborts in that case.

Maybe you need to uninstall the VoukoderPro completely first.

Tested it on 2 systems and it's working here.

P.S.: Thanks for helping to solve this issue.

Seems I missed to replace one GUID, got it working!
