Deinterlacing a 16bpc source with AviSynth

[SenorKaffee]

I recently had old Super8 film scanned. The result I got is a nice HD MOV stored with the Avid DNxHD Codec. So far no problen.

When it was upconverted from 18fps to 25fps interlace artifacts have been introduced. First thing I tried was to open it with QTInput and deinterlace it with TDeint, but then I loose all the nice color information from the scan, which is quite visible when I further process the source in After Effects.

Is there a way to deinterlace in AVISynth with all the color information intact or do I need to find an intelligent deinterlacing plugin for After Effects?

Avisynth works in 8-bit per channel only, and DNxHD offers 8 or 10-bit per channel varieties, so where are you getting 16bpc from? Do you mean 16bpc project in AE?

EDIT: maybe this thread should be moved to avisynth section?
