I did not open this issue specifically for Voukoder Pro (It is also for Voukoder Classic). Because I see that x264 and x265 were removed from Pro in the last update.
So maybe you should consider bringing this feature to Voukoder Classic?
I'm using Voukoder plugin almost 2 years. The render time was normally half of the video duration with NVENC HEVC option (I have RTX 3060 laptop gpu). And NVIDIA Studio Driver instead of Game driver.
6 hours of duration video would take est. 3 hours to render with Voukoder plugin. But recently, it is changed.
Now it takes 7,5 hours of render time for a 6 hours duration video. What happened?
Here is an example. It is rendering for 6 hours, %80. Est. 1.5 hours left to %100.
I'm using Voukoder with NVENC option (RTX 3060 Laptop GPU). Recently, I encountered this problem and don't know why it is caused. Maybe a driver update? I'm using Nvidia Studio driver.
The problem is my actual video duration 58 seconds. But rendered video duration is 30 minutes and the result is the extended version of my 58 seconds. I mean, 58 seconds video extended as 30 minutes so it moves slower than frame by frame.
I'm having trouble with video sizes. A couple months ago or 1 year ago etc... my 1 hour video (1080p 60fps) render sizes were 500-600 mb. I remember these because I'm recording gameplay videos frequently. But I don't know why it's too high now. I'm using default Voukoder settings (HEVC / NVENC).
As you can see, 1 hour video size is generally 5-6 GB.
While the original OBS recording (2.5 hours video) was 3 GB, it is not normal that the video I divided into 1 hour and rendered with Voukoder is 6 GB.
I'm using Voukoder 6.2 current latest version. I tried to render 4K 30 FPS with Voukoder HEVC NVENC default settings and I got error. Here's the screenshot:
