How to convert 50fps to 25fps in GK ?

[r3mix]

I want to convert HDTV .tp captures @ 50fps to PAL 25fps using the full version of Gordian Knot but cannot seem to find any way to do this.

All the guides that I've found refer to using AutoGK in file mode to make this conversion but for some reason AutoGK will not run on my machine. There seems to be some Avisynth issue and it always crashes at the end of 1st pass.

The full version of GK runs fine and I want to use this for its custom cropping etc. Is there something I can do in GK to convert 50fps to 25fps ?

Thanks for any assistance.

This seems to work.
In the GK [Options] tab check the "Use advanced SaveAVS" box.
When you are ready to encode and hit "Save & Encode" in the preview window it will give you an additional multi-tabbed window with additional encoding options. The last tab on the right will be a blue script window. Paste the following into the load-DLLs section....

LoadPlugin("D:\Media\Author\AutoGK\filters\fdecimate.dll")

and the following after the mpegsource line...

FDecimate(rate=25,threshold=1)

Then hit the "Save & Encode" button on the multitab window and you're ready to add the encoding job to the queue with your customised script for coverting HDTV framerate to your local framerate. You will need to customise the file path in the first line and the "rate" setting in the second.

FDecimate plugin is available here...
