Did you encounter any error messages?

You may have the After Effect's composition duration set way too long, this could not happen to Premiere as the video will be garbled if any "blank" is in the composition/tracks' workspace panel. To shrink the workspace, go to composition top menu --> composition settings and edit the duration

This doesn't seem right. Could be the 5fps glitch.

PlasmPlayer and iAvoe:

The problem is that Vegas itself takes a lot of horsepower to render the raw frames, and this is needlessly duplicated if I need to have the same render encoded as 3-4 different formats. Vegas renders the raw frame, then encodes it to whatever format you specify.

No point in Vegas rendering the identical raw frame 3-4 times, which is what a batch render or script would do. This is extremely inefficient in a big render/encode op that takes many hours.

Yep, that's why I suggest you to export first, and then encode into different formats

Constant quantizer is the issue here. Because video encoders decides what quantizer to use for which video frame, and using pixel block-based referencing to drop quality on pixel blocks that has a reference from a full quality source frame, and that's why newer video encoders are using constant rate factor (CRF) mode for a variable quality resulting better compression in the same file size. Choosing constant QP disables this feature.

Same here, I ended up just reusing the same project file over and over (Open --> Saves As New --> Cleanup and start editing)

In that case you can even skip Voukoder, just render a lossless footage and write multiple commands in a batch file (asuming you are on Windows) to use x265/x264/SVT-AV1/QAAC encoders one by one, and multiplex with ffmpeg, roughly such as:

::Video Encode
ffmpeg -i "Sequence 01.mp4" -an -f yuv4mpegpipe -strict unofficial - | x265.exe --y4m - --output "v0.100.hevc"

::Audio Encode
qaac64.exe --cvbr 320 -b 16 -r 44100 --threading -o "v0.100.aac" "Sequence 01.wav"

::Multiplex
D:\ffmpeg.exe -i "v0.100.hevc" -i "v0.100.aac" -c copy "Complete_Product.mp4"

Guess we can add a line somewhere in the bottom of Voukoder says: if export instantly finishes, it failed

I remember VMAF is pretty CPU heavy (likely to be wrong), I would say leave it for a faster rendering or more compression, plus we have some decent x265 settings loaded in there already.I personally would say transport film grain optimization algorithm (FGO, by DarkShikari?) in x264 to x265 & AV1 would be a greater boost in lossy encoding quality than VMAF, though

What I do is copy the old project file (Premiere) and start from there, so Voukoder is somehow configured with it, it might not be the same on Vegas

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
