It might be related that Voukoder needs a raw and uncompressed input.

The modular Voukoder successor is planned to not rely on FFmpeg encoders only.

For me it worked fine using "Export" -> "Voukoder ..." with the latest versions.

The first number vRender is the time VEGAS needs to render the frame. 0.1s means it will limit the fps to a theoretical maxium of 10fps - 0.2s even 5 fps.
I have to admit the last encoding time of 6.9s is also pretty high, but this is within FFmpeg.

Almost 2 minutes to flush remaining frames and writing the mp4 footer. Looks also strange. Maybe i should use an older version of FFmpeg again.

Please make sure you guys don't have mp4+faststart enabled. Faststart processes the whole exported file and can take up to several minutes at the end.

This can also be related to VEGAS. VEGAS has to render the frames first before voukoder can encode them. You will see this in the voukoder log.
The presets can be discussed here: https://www.voukoder.org/forum/thread/592

These options are basically choosing the scaling algorithm. "Point" just duplicates pixels. "Bicubic/Bilinear" are interpolating pixels by averaging them, "Lanczos" and "Spline" are the most sophisticated algorithms and should normally produce the best results - but there are rather slow.
-
Exactly. You can either change the project size. Voukoder takes all data from your projects properties. Or you can scale with a voukoder filter.
-
The rendering process is sluggish, and Whenever it finally reaches 99%, it hangs, meaning it just sits their for a very looooooong time
before the render is completed.
With what encoder(s) / settings / muxer is it that slow?
-
Do you mean HDR?
Currently the connector only delivers YUV 4:2:0 (8 Bit). I also go YUV 4:2:0 (10 Bit) working on my dev system. But we'd need at least 4:2:2 (10 Bit). The pixel format mapping is a bit tricky.
-
I made a small change to that connector. It supports now the new color settings, too.
-
Did you find anything not working properly?
-
You can download a really fresh build here. Caution! It's still hot and not carefully tested.
Consider it as a BETA, but looks fine so far.
-
You are using the "libx264" encoder and the CPU is at 100%.
That's how it's supposed to be!
Everything is fine.
P.S.: If you want to have GPU acceleration use the "NVENC" encoders.

I'm currently in contact with the Magix dev team to find the issue.
-
I installed the beta release back then to try it, and I gave it only a quick test with a plain h264 file with no effects and transitions at all. It happened to be faster (both with default settings) than Voukoder on my RTX2080TI. But as I said: It was not a real test.
-
No, I had difficulties with the SDK and I am in contact with Magix on soving these.
-
That might explain why the Adobe NVENC Exporter is faster than Voukoder.
