And tape output is bad because....?

OK People, from someone who does this practically every day, please can the misleading information. Avid MC Motion Adapters function with a very specific set of defaults, and once you learn what these are and how they are triggered, they function without fail and flawlessly for you. The default motion adapter for 23.98 material in a 29.97i project is standard 2:3 pulldown (both fields, source progressive, output interlaced) PROVIDED THAT your clip has "Progressive" set in the Field Motion column in the bin. That said, since this is what you want almost always when doing this frame rate conversion, you MUST WITHOUT EXCEPTION set any "Unknown" or "Interlaced" Field Motion column setting for any 23.98 clips to "Progressive" in order to get what you want. Since so many of 23.98 clips are incorrectly GUESSED by Avid's interpreter to be "Unknown", when left alone, these clips will have incorrect motion adapters applied (source interlaced (?!) output interlaced, blended interpolated).

So, like I said, do one video mixdown of your 23.98 sequence in the 23.98 project. A video mixdown in a 23.98 project will ALWAYS result in that video mixdown clip to have "Progressive" stamped in its Field Motion attribute in the bin. Then, you can take that clip into the 29.97i project and have Avid automatically apply the proper motion adapter for 2:3 pulldown. Mix that down again to bake in the pulldown and create a native 29.97i clip.

There is no other in-the-box method in Avid MC that will guarantee the proper result. And good lord I see the shoddy handling of 23.98 material all over projects from other editors and all over television. Field Motion should be in every one of your custom bin views if you're even thinking about using mixed frame rates in your 29.97i projects.

I've never seen the default motion adapters in mixed rate material be fluid motion. Perhaps I've never looked closely. IIRC the only way to look at what the automatic motion adapters are doing is to promote the motion effect and look at the settings in the box. From your post it sounds like they are coming up in fluid motion but that is not what I've experienced in the past. Has something changed about this behavior or is it tied to the motion effect render preferences? I would think fluid motion, as powerful as it is sometimes, would be a bad default given the chance for artifacts when all you want it 2:3 pulldown added. I'm surprised that would have to be manually changed.
