I will of course try out the scenarios and report back here.

When I say "skip existing files", I don't want new files to be made anyway.
It wasted my time. Skip means skip.

Win10x64
VTM 21 or VTM 22

Environment
Skip Video file if all required pictures exist on the disk (the content is nor checked)

BUG
Existing files will NOT be skipped but a new file will be created with the addition in the file name: (COPY_0001)
This does not happen in version 20 or before.

4Gb file without that I have the copyright ... problem ...

Thank you.

The Win7 filemanager (explorer.exe) says that a testfile has a Video Pixel Avarage Rate: 7500 kb/s

Thank you for the answer. But I don't mean this. The videos (10.000 files) doesn't have the same length. So "Cut first 590 seconds of the video" is not practicable. VTM should 1. check the video length of each video file. 2. calculate the last xx seconds (xx = Variable that is defined in t...

Is it possible in VTM?
Begin the shoot x seconds (example: 10 seconds) from the end of the video?

Example:
Video ist 10 minutes long.
I need the thumbnails only from 9:50 to 10.00

I have disabled the feature and the problem is gone.

I will add Import/Export list of files feature, so you will be to export the list of "failed" file. Will it be enough? Means "failed file" that all engines must fail? Or does it mean that if the main engine fail fails? My idea: Primary engine is of course "ultimate engine&q...
