Sorry if this has already been answered, but the search is not cooperating with me.
I want my first frame to be captured 6 seconds into the video, but using a standard matrix so that my output collage is a fixed size with a fixed number of frames & doesn't come out 500k pixels long.
If I used fixed interval capture with a set start time, the first frame is always 50% of the interval + the set start time.
Everything I have tried either captures the first screen too late, stops capturing well before the end of the video, or produces an output image with an absurdly large height.
Is there any way I can do this so that my caps start at exactly 6 seconds in & go all the way to the end of the video in a fixed size output matrix?
