detecting black frames

[StainlessS]

i and j are clips not frames. (EDIT: The frame being worked on is current_frame)
It should work similarly to the previous script, you are just swapping apples for oranges.

Both AverageLuma() and AudioMax() are just functions returning a float used in the conditional part of WriteFileIf().


EDIT: Instead of this:

#This is the line that actually writes the frame number of the FIRST frame that falls below the threshold
WriteFileIf(last, filename,  "(AverageLuma(i)<blankthreshold)&&AverageLuma(j)>blankthreshold", "current_frame+1", append = false)

Something like:

#This is the line that actually writes the frame number of the FIRST frame that falls below the threshold
WriteFileIf(last, filename,  "(AudioMax(i,0) < -100) && AudioMax(j,0) > -100", "current_frame+1", append = false)
