  Cinema Tools is changing the Lenght (time) of my clips!!! not just the FPS…

  So something very strange is going on…

  i have a couple long clips shot on a dvx100 in normal 24p mode. When i use CT to reverse telecine
  the material, all but one clip is shrunk in length. At first i thought it was a quicktime issue (the new
  clip say Clip A.rev shows up shorter in length than Clip A when opened in quicktime), but the
  same thing occurs in FCP in a 23.98 timeline. The new clip 24 frames a second, but it’s almost
  as if the file is playing at 30FPS.

  i had to break up 2 of the clips into parts because apparently cinematools cant do an inverse
  telecine on clips larger than 5gig. But for some reason, only the shortest clip (around 3 minute long)
  has the exact same length as the .rev clip. All the clips of 20minutes or so came out as
  smaller files (expected) but that are shorter in length (bizarre).

  to give you precise information according the the Clip Analysis info in CT,
  Clip A is 22:25:20 @ 29.97
  Clip A.rev is 17:17:21 @23.97

  when i press the reverse telecine button, i get no options on how i want to process
  the clips besides @ 23.98 or 24… it says it wants to do a 2:3:2:3 which makes sense.

  arg, someone please help… this make no sense…
  i’m running 10.4.2 and CT 3.0.2

  thanks,
  manu

  also, when i watch the new quicktime clips from CT, the sound is not pitch shifted and plays normaly, but it loses synch with
  the picture because the picture is running at a faster speed…

  does anyone have any ideas? the same thing happened when i took the drive to a friends computer. The only
  other variable i can think of is the fact that i have a Black Magic decklink extreme card in the system… but
  i captured the clips via firewire.

  anyone run into this CT problem before??

  thanks,
  manu

  you’re trying to convert the frame rate of your clip.

  If you are then this is a notoriously tricky operation.

  Have you tried Graham Nattress’s plug-ins? That’s a good way to do a NTSC/Pal conversion, which sounds like a similar thing to what you’re trying to do.

  If you can be a bit more specific…

  No,

  i’m sorry that my question was so poorly worded. I’m simply trying to remove the pulldown added by the dvx-100a when you shoot 24P instead of 24PA. Cinematool recognizes that the media has 2/3 pulldown flags in the video stream, and does an automatic reverse telecine. The file i get out of cinematools is shorter in length (time wise) than the one i put in. Think about it, and hour of 24P @60i should be the same time length as 24P @ 23.98… an hour of video is an hour of video.

  For some reason when i try to do this with large clips, cinematools changes the length of the clip. Smaller clips work fine, but anything over a couple gig makes cinematools do this weird speed up. The funny thing is the sound is not affected, it plays at normal speed, but the video is sped up and loses synch in the new clip.

  am i going crazy, but isnt cinematools supposed to remove the pulldown from the dvx-100 when shot in 24P!? am i the only one having this problem?
