alex2310 First, thanks for your suggestions.

you can see the encoder parameters in the advanced options, but you can't edit (or copy-paste them) manually

Each parameter you can configure in Voukoder does have a name (as you can see in the box below). But this name is not necessarily exactly like on the command line level. In your example the keyframe interval is sometimes "keyint" and sometimes "g". It's not easy to interpret and parse all parameters reliably.

perhaps it's best to leave the commandline uneditable, but make the all the options searchable.

That could be a possibilty. Would that help?

use separately compiled libraries like SvtAv1EncApp.exe, x265.exe

That's not possible. These binaries are compiled in as libraries and used on the C API level. Voukoder is not just a GUI frontend for the exe files (like other tools).

You have set a sample rate of 192 kHz in your audio settings in VEGAS Pro. But ...

Encoder aac [AAC (Advanced Audio Coding)]:
    Supported sample rates: 96000 88200 64000 48000 44100 32000 24000 22050 16000 12000 11025 8000 7350

... AAC only supports up to 96 kHz.

Usually this is set to 48 kHz - which should work perfectly.

The other options are set to its default value (which is the same as if they were not applied). So it shouldn't make a difference.

It is enabled by default. See Where do I find the log file?

Unfortunately this is currently not possible.

I have just tested it with a freshly installed VEGAS Pro 20.0 (Build 403). Everything works as expected.

You might want to try holding CTRL and Shift during VEGAS startup to clear the cache. This worked for me a couple of times in the past.

I see a couple of issues here.

Please select in the export "Video" group the proper frame rate. (Maybe this even fixes that problem).

It was not able to write the exported file to disk. Maybe this is somehow related to the first issue. If not, make sure the current user has write access, and there is enough disk space left.

Please attach a Voukoder log file.

Where do I find the log file?

Main log file

The main log file contains all log data for one single day:

• Voukoder initialization
• All exported files

These log files are located here and will remain for 7 days:

(Quelltext, 1 Zeile)

The files are named by the ISO date (yyyy-mm-dd).log:

Export specific log file

If you have "Create log next to the export file" enabled you can also find it - well ... - next to the exported file. This log file contains only the export relevant information.

Around 5am local time, but that's okay.

Your installation path is wrong. It is supposed to be: C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\IOPlugins

Are you using the free Version of DVR or the non free version (DVR studio)?

Only DVR studio is supporting external plugins.

I can confirm this. Somehow the filter graph does an automated conversion from "full" to "limited" and I don't know why ... yet. Investigating ...

P.S.: This is not related to AV1 or DVR only... it's deep inside voukoder.

The Resolve Connector has the option "YUV (High bit depth)" too. That's also YUV 444 with 16 bit depth.

Currently I am getting 32bit float YUVA input from Adobe Premiere only. But I need to downconvert it to 16bit int to feed it into FFmpeg as it doesn't support float YUV pixel formats. (to my knowledge)

Voukoder does not support FFmpeg command line options, but it does support some FFmpeg filters.

I guess this could work if I add all the comma separated filters in the filter chain above.

ProRes is a group of codecs.

h264 is is a codec.

MOV is a container format.

MP4 is a container format similar to MOV.

A container format can contain audio and video streams encoded with a codec:

This plugin can encode ProRes video streams combined with ALAC, AAC (and more) audio streams in a MOV (or MKV) container, yes. In this case no h264 is involved at all. Note: The ProRes encoders are not certified by Apple (but should still work).

Voukoder 13.1

Make sure you are using the latest connector for your application(s). For using NVENC (SDK 12) encoders driver version 522.25 or later is required.

Fixes / Changes

• Using FFmpeg 6.0 build 20230405
• Encoders
  • libfdkaac: Supporting the libfdk-aac-2.dll again

Voukoder 13 should work now with qsv.

You're welcome. Thanks for notifying me about these errors. This helps making this project more reliable.

So what error do you experience? What is the problem?
