export video in backwards

Hi. im not sure if toon boom studio can do it, but if not id like to know about a video editing program that can. i have a short clip i made - about 500 frams.
i need to export it only in backwards - meanning i want frame number 500 to be the first frame, 499 to be the second and so on.
the only way i figured out doing that is by exporting the video to PNG files and then create a new project and import all the PNG’s in the order i want. im sure theres a faster way of doing that.
thanx in advance

Either, use “Create Advanced Cycle”
Use the sliders: set the First Drawing the last one, set the Last Drawing the first one.

Or, any Video-Editor should be be able to reverse any footage required.
