The issue is that at least one pixel format has to be mentioned here:
[14:00:04] Opening codec: libx264 with options:
Normally this has to be yuv420p by default.
Please try loading, saving and loading the settings again.
If it still fails delete all saved presets/templates and start with a clean new project.
I have added FFmpegs "g" parameter so you can change the "group of pictures" size. Available in the next version.
Deinterlacing
You have to set premiere to export interlaced material (and the correct field order) so Voukoder knows it gets interlaced fields from premiere and can convert them to progressive frames. If you set it to "progressive" Voukoder already gets progressive frames.
Framerate
I am not exactly sure about the 25i to 50p conversion. But the more I think about this, the more I get the impression this is not about a single filter (bwdif) but more about a whole filter chain. Do you know with what FFmpeg command line you'd get the expected result?
BWDIF
Fixed that. Thanks for pointing it out. Will be available in the next release.
LOG
This is fixed already and will be available in the next version
Do you have a sample video for this? before and after?
Actually premiere does the rendering and Voukoder simply encodes the rendered frames.
Both right! It is important to differenciate if you play that video locally (before you upload it to YT) or if you play it on YT. But in both cases it is not a bug in voukoder. It is just a question of the used settings.
Can anybody else reproduce this? Works fine for me.
So you basically need to opposite of what i've shown above?
Unfortunately this is a different filter "adelay". They could've really combined this in one filter.
Maybe it doesn't really make sense to pass through FFmpegs filter 1:1. Maybe I need to put more logic in voukoder to make this more user friendly.
With this setting I was able to correct it:
In Audacity it looks okay:
P.S.: Yes, currently only times are working, specifying samples seems to be broken...
Normally the FPS is taken from the project settings. Maybe you can copy&paste the voukoder logfile?
Can you try to reproduce this with FFmpeg on the command line?
This will be fixed in the next version.

It is most likely an AMD driver issue. You might also post the Voukoder log file.
It has float data as input. This means values from (theoretically) -1.0 to +1.0. (Over/Undershooting is still possible).
32bit here is the precision (simplified: the number of decimal points) of that value, not the resolution like with PCM (integer).
"float" as a type has always a size of 32 bits (or four bytes)
In some formats you have also 64bits of precision available, which is actually called "double"
Voukoder 4.1 has fixed the presentation of the list of available encoders and formats/muxers with Video/audio dis- or enabled.
VEGAS users: Please update to connector 0.7.0. There is now an option to disable or change audio settings.
Just a small bugfix release fixing the small issues below.
For using NVENC encoders driver version 436.15 or newer is required.
Thanks to my all supporters - especially the platinum tier patrons ValnirÆsirsson and Gronkh!
Maybe it has to do with the options?
-aac_coder <int> E...A.... Coding algorithm (from 0 to 2) (default fast)
anmr E...A.... ANMR method
twoloop E...A.... Two loop searching method
fast E...A.... Default fast search
-aac_ms <boolean> E...A.... Force M/S stereo coding (default auto)
-aac_is <boolean> E...A.... Intensity stereo coding (default true)
-aac_pns <boolean> E...A.... Perceptual noise substitution (default true)
-aac_tns <boolean> E...A.... Temporal noise shaping (default true)
-aac_ltp <boolean> E...A.... Long term prediction (default false)
-aac_pred <boolean> E...A.... AAC-Main prediction (default false)
-aac_pce <boolean> E...A.... Forces the use of PCEs (default false)
Does this happen with the Fraunhofer AAC encoder too? Did you test this?
What about if you export raw pcm?
I guess there might be an issue with the 32 bit float data coming out of premiere.
I am working on an update making this possible. It is in the testing phase now.
Voukoder 4 can correct this with the "atrim" filter (both in milliseconds and in number of samples).
