Looks like a color space interpretation error but I have never dealt with that, try make a new copy of this project, and then specify BT.601 instead of default BT.709 in the following 3 locations:
Premiere Sequence Setting - Work Color Space: BT.601
Premiere Media Export - Video tab - Color Space: BT.601
Voukoder Configuration page - Select encoder - Side Data tab - MasterDisplay: Primaries=BT.601
The encoder failed to start, and was not able to send a "fail" API call to Voukoder (my theory), probably are because of those unsupported graphic cards
In most of cases I've seen, its the media player. I would say download mpv and check again. Btw the only video filter in Premiere (afaik) that could make that kind of color difference is "Brightness & Satuation"
And, unless new compression methods show up, AV1 is more of a cranked up x265 with depreciated features due to slowness added back, but I could be wrong since I have not been following updates
AV1 is still under dev, and does not provide a stable image output, and you might not able to view render results on mobile phones unless you have a good media player app. Generally not recommeded for reliability dependant workloads
I remember the installation requires manually placing connector plugin into "Plug-Ins\Common" folder under correlated progian (After FX in this case).
Here's how to do it:
1. Select x264 encoder
2. select a desired preset
3. change "rate control" to CQP
4. adjust QP value
CQP is basically CRF, except you lose some available compression under the same quality settings, better used for compression testing compred to CRF.
Note: You can do it on x265 encoder as well, but wait for the next version that comes with presets.
All video encoder has data smoothing filter built-in for better compression, not just quantization filter
Thanks for your detailed reply
OBS works fine
NVIDIA Driver should be recent enough (has auto update)
Resizable bar is not enabled
It looks like would be VEGAS Pro, Voukoder or Connector's fault then, try replace them.
I don't think the file system or operating system could cause this kind of error, but you can try CHKDSK, SFC and DISM commands in CMD (they have built-in help file to check for usage)
That's a downside of video compression. For Minecraft, you can reduce CRF option to 16 to make the video look better
[18:10:02] FFmpeg: Failed unlocking input buffer!: generic error (20): (Ú8
The card was an RTX 3080 with 32GB RAM, and the error looks like came from the software
Try:
Record with OBS, select NVENC encoder and see if recording fails
Disable audio output (not likely to be the case)
Or just use HEVC encoder since you've got a strong CPU for encoding tasks
Guesses:
Driver was outdated;
Second handed card that was loaded with a mining BIOS (not likely);
Operating System build is outdated (not recorded in log);
Resizable-Bar is enabled, try disable it;
x264 and x65 from ffmpeg are advantageous in double pass encoding. In single pass, you already have software/native encoding in Resolve, which I consider equivalent in speed/performance.
As far as I know only single pass is available in Voukoder yet, for SDK constraints. If you want double pass x264/x265, you may export to DNxHD in Resolve and double-pass with ffmpeg/Handbrake later.
2 pass encoding is basically analyze how much quantization compression per frame (x264), or per block/unit (x265) in pass1, then in pass2 encoder adjust the quantization compression level more evenly. So overall you still get lower quality (and slower) than CRF mode (constant rate factor, 1 pass), if you give a higher bitrate in pass2, then you defeat the purpose of 2 pass, so at least in video production/editing phase, it's not recommended to use 2 pass at all 
I've never used Vegas, but I'm comfortable with simply working on multiple projects, only the "last station" being final. If you want some lossless codec (Cineform or ProRes) in intermediate rendering, in this case you won't necessarily need Voukoder; if you want lossy codec just go for exporting the whole project.
I've created a pull request to submit the parameters, it just needs some time to be tested and updated to next/later release. Currently you need to go to Option tab, and find, apply the settings yourself
Unfortunately hevc lossless does not seem to be implemented in Voukoder even though it is implemented perfectly in ffmpeg with a transcode script such as this:
Codeffmpeg -i "INFILE.MOV" -c:v libx265 -x265-params lossless=1 "OUTFILE.MOV"x264 cannot actually achieve lossless. It's lossless setting is close but ProRes422 is generally a little better quality, faster rendering, and smaller. MagicYUV is another possible option.
Hi, afaik currently there are no available presets. I've created a pull request to submit them and it needs time to be tested and updated to next/later release. Currently you need to go to Option tab, and find, apply the settings yourself
Well, if we already have hardware encoding with studio version, that doesn't nearly defeat the purpose of Voukoder? I very much appreciate Voukoder and it's a great piece of software, but except ProRes, VP9 and AV1 (which are very welcome of course and I applaud the developer), studio version already provides QuicSync H264 and H265. I have found they are faster, actually.
In terms of quality, x264 and x265 are better than hardware solutions, because hardware solution requires money to make larger circuts that implements code the software solution already does (if the encoder section costs under 100USD, they are no match with software encoding), the only advantage is in lossless codecs where the hardware encode runs cooler and faster.
2-pass requires a stat file output, and video output on the 1st run gets disabled. To implement this requires a software level change on the video editing program, because they would expect to output a video, and Voukoder is an intermediate plugin... I guess?
It seems that voukoder is still using x265 v3.4. These parameters are build around v3.5 and since x265 devs sometimes change the parameter name and enabling-disabling some feature, it's better wait for a new Voukoder release before impementing them
It feels Voukoder itself was corrupted, try reinstall it. Multiple encoders failed to load from start; go for older/other After Effects version as well.
If you are using PotPlayer, change to MPV and see if that displays correctly
Check your OBS/other recording software video options, the source has to be Full color range and BT.709 color space as well, I know you said Premiere it looks right, but still try check that.
Check the Output - Video tab, the color range is supposed to be Full instead of Limited
Try 8bit instead of 10bit, both set in recording and Premiere export.
