 .SYNOPSIS
     Extracts a specific frame of a video file to a PNG image using Get-LastFrame.ps1, requiring -Video and -Frame parameters from that script.
-    The image filename used for the -Image parameter is automatically derived from the -Video filename, with a "-" followed by the "-Frame" value padded with zeros (maximum of 4 digits) inserted before the image file extension (e.g., P01.mp4 for frame 10 becomes P01-0010.png).
+    The image filename used for the -Image parameter is automatically derived from the -Video filename, with a "-" followed by the "-Frame" value padded with zeros (at least 4 digits, wider numbers are not truncated) inserted before the image file extension (e.g., P01.mp4 for frame 10 becomes P01-0010.png).
 .PARAMETER Video
     Path to the input video file. Can be absolute or relative to current directory.
