Oddball framerates

[m2dpost]

Hey Folks, I did a little experimenting with different frame rates with my TH and I am really confused by what Yuneec is doing with frame rates. Since I am in an NTSC world I have looked at rates of 29.97, 23.98, 60 and 120. Also I'll add that I am looking at the frame rates in Quicktime player's inspector window and in the inspector in Final Cut Pro X. Oddly enough these are the rates I am seeing.

Recorded at 30 on CGO3+
Quicktime shows 29.97 (I would expect that)
FCPX shows 29.97 (NOTE: This is the only frame rate that matches, but plays back stutters in FCPX and I have to convert to ProRes in Compressor to stop the stuttering.

Recorded at 24 on the CGO3+ (I would expect to see 23.98 in other apps)
Quicktime shows 23.99
FCPX shows 23.99 (Playback looks fine)

Recorded at 60 on the CGO3+
Quicktime shows 59.91
FCPX shows 59.92
Neither one of these are standard frame rates. However the footage seems to playback okay.

Recorded at 120 on the CGO3+
Quicktime shows 119.96
FCPX shows 120
Playback in both apps seem smooth on the frame rate, but man is there a lot of compression artifacts and aliasing in the footage.

So I am just curious if any of you are experiencing these same odd frame rates. And if you are seeing the same bad aliasing in the footage.

Here's the 120fps footage.

Well, 23.98 and 23.976 are pretty interchangeable, but 23.99 is definitely non-standard.

23.976 is only correct if pulldown is used. There is also true 24p.

Agreed, but 23.99 that the CGO3+ is giving me is way not standard.
