This was exactly the context of my bug report to Avid - that regardless of whether it could be known that a clip was truly progressive, if MC could guess correctly the frame rate to be 23.98, it should assume that the clip is progressive. Having a value of "Unknown" for Field Motion means that the source value in a motion adapter is always set to Interlaced.

I remember you posting about this before now that you have jogged my memory. So when I recheck the process tomorrow I will inspect the ama bin with the 23.98 clips. The AEs told me they were seen as 23.98 but as you point out that is a different parameter than the field motion. I guess I shouldn't dwell on the fact that everything that is 23.98 is progressive, at least to my knowledge, so having recognized the frame rate it would seem logical to assign the field motion to progressive. Anybody know of 23.98 media with interlace? I'm sure in this whacky transcoding, redemodulating era where baseband is becoming a thing of the past I'm sure there's a way to discombobulate a file into 23.98 interlace. Hey I'm sensing a challenge here.
