How to make decimate drop combed frames only?

[soujir0u]

Hi, I'm using IVTC on a credits scene but decimate (from Decomb 4.00) seems to drop progressive frames instead of combed ones sometimes... Is it possible to make it drop the combed ones only, and leave the progressive one?

You can use the manual override feature to force decimation of desired frames. There is no automatic solution. You are still limited to the declared decimation rate, of course.
