Generate scene images

Scene detection algorithm - lets you specify the algorithm the application uses to find the best screenshot:

• Largest frame - the frame with the largest size in bytes.
• Largest keyframe - the keyframe with the largest size in bytes.
• Largest JPEG on keyframe - the keyframe with the largest size in bytes after being encoded to JPEG. This method gives the best result, but it is also the slowest one.
• Chapter image - uses the image at the chapter mark.

Scan distance - the number of seconds to scan, starting at each chapter.

Folder for chapter images - lets you specify the name of the folder (without a path) in which the chapter images are stored.
