AutoGK deinterlacing question

[hello_hello]

This question is really just to try to satisfy my curiosity.

When AutoGK first analyzes a video it creates an interlace.log file, a section of which looks something like this:

true-true
true-true
true-true
false-true
false-true
true-true
true-true
true-true
true-true
false-true
false-true
false-false
false-false
false-false

While I guess the interlace.log file is some sort of frame by frame log (although I don't understand what "false-true" or "false-false" etc. means exactly) I've not seen any reference to the log file in any of the scripts AutoGK creates and I don't recall ever seeing another encoder GUI create a similar log file.

I'm just wondering why AutoGK creates this log file and whether it's actually used when deinterlacing the video.

Thanks.
