Ok, now that I have tried the Decomb telecine filter in avidemux on an entire episode I have noticed a couple of things. When using the TDeint filter, I get a very nice picture (except for the field-blended frames, which there is a lot of) and with the Decomb telecine filter I have no field-blending (for the most part) but now in numerous other places I have a combing effect, so should I mix and match frames from both encodes (using decomb telecine for encode 1 and TDeint for encode 2) to produce the cleanest possible picture?
or maybe even do three encodes, where the third one I could use the seperate fields filter (for those fields/frames that can't be recovered properly using either of the other two methods) ?
