Unable to start VoukoderPro: FFmpeg error.

Hey,
so I just saw the VoukoderPro beta and figured I will give it a try. First, I noticed that i couldn't open the "Scene Designer" (in Vegas 20). So, I started the application (with admin perms otherwise it wouldn't open). I just tried to reconstruct my previous settings and wanted to see the result. As the title already says it gave me the following error: Unable to start VoukoderPro: FFmpeg error..
I already installed ffmpeg on my pc and even added it to path, so I don't know how to fix this error, anyone of you have an idea?

Regards,
2sa

Can you export and send me that scene file?

well as I don't know how things work in VoukoderPro my config might be the problem, but here you go.


I was not able to upload it so here is what's in the file:

In the video encoder node switching from CUDA to YUV 420 should help.

ok it seems to work now thank you.

did you maybe spot something off or weird in my settings because this is a bit more advanced for me ig.
and is there still an option to resize your video with zscale or whatever it was called

Zitat von Joe24

Or if you want to use your graphics card hardware to do the scaling:

(Video Input) -> (Video Filter: CUDA Upload) -> (Video Filter: CUDA Scale) -> (Video Encoder: NVENC H.264 with input data type set to "CUDA") -> (Muxer) -> (Output)

You can unzip and import this file into Scene Designer: scene2.zip

If i try that my I have the ffmpeg error again
