OK. I thought this had been settled years ago, but I've read some things that now have me a more than a little confused...

I read the article by the illustrious Adam Wilt regarding Cineframe24 and thought it definitively showed that Cineframe24 was not tru 24p.

Now I read a post where it is said that those results were skewed as he had not removed the 3:2 pulldown.

And since Cineform does the pulldown removal, I thought it might be appropriate to ask here:

Is the Cineframe24 with pulldown removed 'true 24p' or not?

CineFrame24 while is does product 24 frames per second, it is not sampled at 24 or 48Hz, but at 60Hz causing a temporal jitter.

The Sony V1U fixed this with a 24/48Hz sampling of the sensor.
