[vdcrim]

From what I see the frame numbers are corrected before writing them to the qpfile when the output fps is different from the input. That means that vfr.py and the macro above should produce the same result if all is correct.

To avoid that possible inaccuracy the readme talks about you can instead add a new line of contiguous Trims at the bottom of the script, and then use the --ofps value as --fps and drop the former from the command line, and add --reverse as well.
