On the (De-)Interlace/Telecine tab for Avisynth, TDecimate in Hybrid supports modes 0, 1, and 2 (out of the seven modes). Mode 1 uses the dupThresh parameter for duplicate frame detection. But there is no setting for this in Hybrid.
It seems like it should be added, and greyed unless the Mode is set to 1 for TDetelecine.
It also seems like Mode 7 should be supported, along with the vidThresh parameter, again greyed unless Mode is set to 7.
Finally, there are a number of advanced parameters which it seems like Hybrid should be able to support, like maxndl, chroma, denoise, blockx, blocky, and sceneThresh.
