Hi GMJCZP,
I am really no FFmpeg expert, I got all these advanced parameters from other users...
You really use a negative value for sc_threshold?
The FFmpeg docs say that the range for sc_threshold is 0-100. No idea...
I made a few short test conversions using your parameters and mine, but I could not see too many differences (my script was slower).
Whatever, as usual you should use whatever works best for you, do some comparisons for sources you know well...
Cheers
