Inverse Telecine?23.976 avi film to 23.976/3:2 pulldown?

[mikeny]

Hi. I was wondering if it was recommended to leave this default Inverse Telecine option checked when selecting the NTSC DVD (Film) option in the wizard of TMPGEnc Plus?

I was under the assumption that the inverse telecine was only necessary when going from 25fps Pal to 23.976 and I was surprised when I loaded an .avi already at 23.976 fps that this was what was going to happen. Was I under the wrong assumption?

If not, is this because TMPGEnc Plus is not reading the .avi corrctly? Is there a way to load a d2v project or something along those lines to make TMPGEnc Plus realize the actual frame rate, like you can do with an mpeg and DVD2AVI?

...or should I keep the Inverse Telecine checked?

Thanks in advance.

Inverse Telecine is only for 29.97 to 23.976 and only if
the original source was actually telecined ( as from 24 fps film).
If you do an IVTC on straight 29.97 NTSC as in TV shows
you will get a mess.
