I see a couple of issues here.

[18:02:53] Timebase:        1209076067/1928261632 (1.59 fps)

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.

Thema

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?

Please try 0.12.4.

Can you provide a sample clip again so I can investigate it? Thanks.

Nice! I shouldn't be working that late anymore. It's almost 11pm here.

0.12.2?

Okay, please try connector 0.12.1.

And for the coders in this forum - This is the current code:

std::string VoukoderFormat::GetTimecode(double seconds)
{
    std::stringstream timecode;

    // HRS
    const int hrs = std::floor(seconds / 3600.0);
    seconds -= hrs * 3600;
    timecode << std::setw(2) << std::setfill('0') << hrs << ':';

    // MIN
    const int mins = std::floor(seconds / 60.0);
    seconds -= mins * 60;
    timecode << std::setw(2) << std::setfill('0') << mins << ':';

    // SEC
    const int secs = std::floor(seconds);
    seconds -= secs;
    timecode << std::setw(2) << std::setfill('0') << secs << ':';

    // FRM
    const double n = m_info.video.timebase.num;
    const double d = m_info.video.timebase.den;
    timecode << std::setw(2) << std::setfill('0') << std::ceil((seconds * d) / n);

    return timecode.str();
}

I'm not sure about the last std::ceil (always round up) at the end ... or if it should be a std::round (round to nearest integer) ...

Right, I forgot about the fractional framerates ... working on it again.
