Save automatically any number of screen caps, with Auto Movie Thumbnailer
Auto Movie Thumbnailer is a free program that scans your video files and creates automatically thumbnails, that is screen captures, of whatever number, quality and size you like.
Auto Movie Thumbnailer is able to scan at once several folders and videos, even apply a watermark to the screen caps it makes.
The program supports also command-line arguments, in case you feel yourself as a “power user” and it can generate an HTML presentation of the screen caps.
If you need some scenes of your movies the easy (and also powerful) way, this is a program you really want to check out. The more screen caps you create, the greater your power of choice is.
