[ERROR] Unable to process one or more files. Remember image files should be named /frame. where INDEX represents the frame number starting from 1 and DIRECTORY and EXTENSION are defined by command line arguments (e.g. frames/frame1.png). Please check if:
The files exist
The files are all valid image files
The name of the files given is correct as per command line arguments
The program has the necessary permissions to read the file.

Use backend.py -h for further documentation

mee too, do you solve it?

I gave up
