Okay here's where I am still not sure about the language:
"even when the footage has been previously edited and suffers from flash fields."
Does this mean random cadence like I would get when I take all my DVCProHD 23.976 filed masters and have the deck add pulldown to capture as 59.94i material in a 59.94i project and then edit as if everything is 29.97i? Or
Is this referring to a flash frame with an edit beginning or ending on a split frame where one field is one shot and the next field is a different shot?
In my DVCProHD case, which is the way we had done all our shows up until we switched to a 23.976 workflow, all the edits would be Field 1 dominant so there would never be a split frame edit in that sense between shots but each new shot might start with either a single, double or triple field of the same moment in time. These fields would be individually half vertical resolution given the Psf nature of spreading odd lines to one field and even lines to the other field. When I break it down this way I wonder how the circuitry/algorithms handle when a new shot starts with just a single field of a moment in time. Does it line double or blend that with the next field(s) when creating the output 23.976 frame? Or maybe it analyzes that the first field of the new shot is only one field and then ignores it and goes with the next field and the following ones to determine what the final output frame is. I am beginning to appreciate more and more all the subtitles involved in the process.

BM sells Teranex as being able to handle reverse telecine on the fly. We have had success doing that, but it wasn't obvious in any way. Might the Snell & Wilcox box be better? Maybe. Is the price difference worth it? Not to us. If it doesn't work for you, sure, go to the "cut up the sequence in MC and go shot by shot having it find the cadence" approach. But what if it does work as it has for us? Wouldn't that be a huge timesaver?

And I don't like the implication that I don't know how it's supposed to work or don't know what settings to use to make this work. It does not work. It might work sometimes. To me, that is as good as saying it does not work. "Sometimes" is not worth the effort of capturing something only to have to go through it cut by cut to see it fail in places.On Wed, Jul 20, 2016 at 1:09 AM, bigfish@...

Flash fields are that extra field of a different shot because the cut happens on a split frame of an already edited segment, often referred to as flash frames, perhaps this is just a bit different terminology than I'm used to. With random cadence you don't get flash frames just the cadence is different for each shot. I know you know this. I guess one interpretation of flash field could be when you pick up a shot on a split frame and it's still the same basic image but only one field of it before the next moment in time. It sounds like this unit does what I'm asking for. Which specific Teranex model are you using to do this?

Yo do have to get all the settings right. And sometimes it goes awry. But for the most part it does exactly what you are asking it to do which the old Teranex (Before BM purchase) also did.

Teranex is unique because it can automatically remove cadence (3:2 pulldown) from video when converting 24 fps, even when the footage has been previously edited and suffers from flash fields. That's perfect for mastering clean online content!
