In the latest version the plugin identifies as "Voukoder" again.

I wrote an article about this effect: The mystery of delayed AAC audio tracks

I strongly suggest to use uncompressed (PCM) audio for intermediate files and only compressed/lossy codecs for the final result.

Voukoder does not multiplex at the end of encoding process.

It writes audio and video interleaved already.

If you have delays at the end make sure that "faststart" is not enabled.

I think so, yes.

Sorry for putting up some explanatory stuff here ...

The error message is back with connector 1.2.4. Seems Adobe has disabled that feature somehow.

Take a closer look

it is yuva444p16le

Please try connector version 1.2.4. It seems your processor is not capable of the AVX/2 instruction set and I had to make a little change for this path.

Does the file look good when you play it on your local PC (NOT on Youtube) with videolan or mpc_hc?

Is it only blurred on Youtube?

That's because of YT reencodes all uploaded files. If you are a small youtuber you have to play some tricks to get a better video quality.

One is to provide a higher video size to get more bandwidth.

Found the issue. You don't get any alpha channel information because the connector you're using does not supply any alpha information:

For some time now the connectors provide a different format:

So it seems you are still using a very old connector, even if you have installed the latest one. Please perform these steps:

1. Uninstall all premiere connectors from the control panel (Apps & Features)
2. Manually delete all Voukoder.prm and VoukoderR2.prm files from these folders (and its subfolders):
   1. C:\Program Files\Adobe\Adobe Premiere Pro 2020\Plug-Ins\Common (Replace the version/year numbers)
   2. C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore
3. There should be no Voukoder.prm or VoukoderR2.prm left on your system anymore
4. Install the latest premiere connector again.

This should help.

btw. Voukoder can only encoder (with or without GPU) what it gets from premiere/the nle. So if premiere renders frames slowly it and does not give enough raw frames to voukoder, it will more or less wait for premiere and thus GPU load will decrease or even stall. That might be related to your projects complexity (filters, effects, ...).

Good to know.

Please enable low level logging and attach the voukoder log file to your post.

The tricky thing was that premiere feeds in 25 frames (50 interlaced fields) and the deinterlacing method "bob" creates 50 full frames out of each field. So it doubles the export frame rate. Normally voukoder creates all frames by itself and marks each frame with an unique and incremental PTS (Presentation time stamp). The "bwdif" filter added the additional frames by itself, so Voukoder didn't know about the correct next PTS value. Additionally the interleaving functionality had to be changed to keep the audio and video at the same length and in sync.

Does it help if you use the setparams filter as a workaround?

This is more a feature request than a bug report. But it not that easy to implement.

The "adelay" filter works by modifying the PTS not by actually adding silence.

I can confirm the bug and need to work on it.

Alright, Chris. It took me around 7 hours today but it seems to be fixed now. And it is as easy as it can be. Just keep the default video settings (25i, tff), add the bwdif / yadif filter and start the export.

Available in the next release.

So it seems I'd have to add the dpb_size parameter to both nvenc encoders, right?

avwtp ... as refs and dpb_size are not the same anymore, right?

I will go through all bug reports on the weekend, but ...

• Are you using the latest version of the connector? If so: Can you install the previous version of the connector, does this one work?
