Apple Cinema Tools 4 - Manual (Page 127)

• If Cinema Tools is unable to complete the conform process for a clip, that clip is moved
into a Cinema Tools–created subfolder named Skipped. (A clip is not processed if it
doesn’t contain a video track, if the frame rate is not supported, or if no codec is found
for the video track.)
• A text file named “conform.log” appears at the top level of the folder. This log gives
the date and time that the process started and ended, for each clip. If any problems
were encountered, such as running out of disk space or memory, an error message
describing the problem also appears in the log.
Reversing the Telecine Pull-Down
When you use a telecine to transfer your 24 fps or 23.98 fps film to 29.97 fps NTSC video,
the typical way the film’s frames are distributed into the NTSC frames is by the 3:2
pull-down method. The 3:2 pull-down method, described in
Working with NTSC Video ,
inserts extra fields of video. The reverse telecine process removes the extra fields (as
shown in the illustration below), changing the frame rate of the video to the original film
frame rate. In other words, the reverse telecine process reverses the 3:2 pull-down. Reversing
(or removing) the 3:2 pull-down provides a one-to-one relationship between the video
and film frames so that your cut lists are accurate.
