I note you are using the Windows version. The Gimp-GAP code base is about 10 years old. I don't know how well it is being maintained or compiled for Windows. Try it in 'Compatibility Mode' for an earlier Windows version. I compiled my own for Ubuntu and what you see indicates GAP cannot process the video. Check the screengrabs?
The correct frame rate appears after you select a video. It works well with VLC re-records. I found that just entering how many frames you want is good enough. GAP will try to fill those frames. Also 'extracted frames are stored in one multilayer image' makes it easier to work with in Gimp.
Cheers.
