max() arg issue

[que-vector]

Hi,
unfortunately I get the following output after using your script. The input files in the directory frames are .tif files with a size of 888x2056 px.
Any ideas?

(tif2video) PS C:\Users\robert.wendt\Desktop\tiff2video\tif2video\data> py .\create_video.py -v --img_dir C:\Users\robert.wendt\Desktop\tiff2video\tif2video\data\frames --fps 1 --video C:\Users\robert.wendt\Desktop\tiff2video\tif2video\data\testvid.avi --fourcc XVID

Output:
#. Create video file from images in directory: C:\Users\robert.wendt\Desktop\tiff2video\tif2video\data\frames

    max_frame_width = max(img_widths)
                      ^^^^^^^^^^^^^^^
