Why CCE forces 24fps from pure NTSC source?

[iomagic]

I am converting the trailer from "The Wall", which is NTSC 29.97, so I exported d2v file with IVTC set to NONE. Double-checked, it reports 29970 in the d2v file. Now I converted it with CCE; Try to import this file into the Scenarist as non-drop frame, and the file gets rejected:

Error: Frame Rate (1 = 24 000 + 1001(23.976)) is wrong

When I did a pulldown on this file, it got accepted as drop frame source.

Did CCE changed the frame rate?! Or I did something wrong?
I did not check "progressive" or "top field first", only "DVD compliant".

Does it have anything to do with RobShot GOP setting 3-4 versus usual 3-5? I wouldn't think so....

Puzzled. And frustrated. :)

I recently made a full back up of The Wall.

the trailers are interlaced, I DVD2AVIed it at 29.97fps
my .avs file looked like this:
-----------------------------------------------
LoadPlugin("D:\WINDOWS\system32\mpeg2dec3.dll")
LoadPlugin("D:\WINDOWS\system32\decomb.dll")
Mpeg2Source("xxx.d2v")
Telecide(guide=1)
Decimate(cycle=5)
ResampleAudio(44100)
-----------------------------------------------

put it in CCE encode it as if it was a progressive source
then use pulldown.exe

when importing it in Scenarist use drop frame

hope this helps :D

Thanks, it won't help on this particular one, since I already gave up and downsampled it with ReMpeg ;)
But for future that would be usefool :)

Still, the REALLY serious question is:

We had the source in full, true 29.97fps.

When it passed through conversion, it lost buncha frames, because we made a film out of it with dropped frames.

Doesn't that make you mad?! Why should we deliberately throw away third of the information from our movie?! Isn't there a way to keep all frames and convert at 29.97?
