Still no insights on a previously posted "frame rate" query, so I will rephrase - in the interest of maintaining best video quality.

PD11 has two NTSC frame rate settings: The 30 FPS is, more than likely, 29.97 - the project default.

In that mode, why does a warning appear to the effect that "29.97 FPS of the input file does not match the 29.97 rate of the project?" Make sense to you? At other times the warning reads that "the 30 FPS input file does not match the 29.97 rate of the project."

Is prior-to-editing conversion desirable in these instances? Or should the "TV format" warning, under OPTIONS|CONFIRMATION, simply be turned off and ignored? The cautions appear in both drop and non-drop modes.

And what of 24P: is that done during production by specifying 24P in the output profile. If so, does PD perform some sort of pull-down, perhaps degrading video? Can the user specify how this is handled, as in higher-end editors? Or are there simply no 24P-specific controls in PD11 ??

Do you have "drop frame" checked?

Edit;

Sorry I missed that in your posting.

On my videos, which are 1080, 60p, I select 60 frames and drop frame.

Hi,
After reading so many MediaInfo text files on a huge number of video clips I am not surprised at a warning popup by PDR. At camera consumer level the actual production by cameras to a precise frame rate is very variable. While in some cases the variation may be 29.966666fps or 31.04fps for example. The track split into frames of an data media file is only to assist in editing and for display. The real significance is what the output is going to be.
Just my opinion.
