VTM 26.0.0.2 for multi cores

I use a I5-13500 processor with 6 power and 8 efficient cores and an internal GPU.
I compared the required time to work through 10 videos. All videos are different, but need about the same time to work through.
The time needed dropping all 10 fils at once to VTM is more than 2 times longer than starting 10 instances of VTM each working one file only.
I guess this effect will get stronger with even more cores.

Did you use the Magic button to process the videos?

I don't know how to do this!
I have installed VTM only, not videonizer.
I mark the video files in windows file explorer and drop them on the desktop icon of VTM. Up to now, VTM works file after file. I don't know how to tell VTM to use the Magic mode automatically in case I drop more than one file.

You don't need Videonizer for that.
The Magic button is right next to the regular Start button.
You can also control the "CPU Load" during the processing with 5 possible values: MIN, 1/4, 1/2, 3/4 and MAX. You can change the value on the fly. Default: MAX.

Indeed this accelerates a lot! So my title was wrong:
VTM is optimized for multi cores!
But Magic mode seams to be accessible inside the user interface only. I would like to use Magic-Max from the command line tohether with the /nc parameter.

I decided not to expose the feature in the public command line interface.
Only Videonizer can use VTM command line interface for Magic processing.
