cinema tools 24 p standard and DVX100
Has anyone here successfully done a batch reverse telecine on 24 fps footage from the Panasonic DVX100 camera using Cinema Tools? These clips were shot with the standard not advanced 24p mode so with the 2:3:2:3 pulldown cadence.
If I manually find the A frame on each clip and reverse telecine each clip the process works well but there are hundreds of clips!
I can’t think of any way to batch this process since the first frames of the clips are all different and Cinema Tools does not automatically find the A frame. The auto reverse telecine window does not appear.
My other solution is After Effects CS4 which seems to auto detect the A frame and perform a pulldown but I would then have to send all the clips to the render queue. So I would be potentially losing quality there unless I render out ProRes 422 with fantastic file sizes. When Cinema Tools performs the reverse pulldown is it actually recompressing?
Does any one have any ideas before an assitant editor steps in to perform these mind numbing tasks worthy of a Marxist diatribe on the alienation of labour?
Thank you for your input,
Phil

Thanks Dave.
Yes I have AE CS4 on the same machine as FCP Studio 3.
I did a test and AE interprets the pulldown removal correctly for multiple clips. You just have to interpret each clip individually but at least you don’t have to find the A frame manually like in Cinema Tools.File sizes for ProRes 422 are not too bad when it is SD.
I made an output in AE which was basically DV resolution with DV pixel aspect ratio but Pro Res 422 compression.The editing will be in Final Cut and it accepts the footage no problem even if it does call it the phoney baloney 23.98 on the sequence settings.
Cheers,
Phil

Hi phil,
did you figure out how remove the pulldown from 24P mode (not advanced?)
i have the same need ,
i need to convert DVX 24P mode to Progressive DPX (to grade it in Assimilate Scratch)
the editing has being done already at 29.97 , but i guess that i can remove the pulldown and be able to have 23.98 Prograssive frame in sync right?Thanks

Gabriele,
If you’re footage is already edited, you might try a solution that I’ve had success with. Export the sequence as a Quicktime Reference then run it through compressor with the ProRes codec, except in the settings turn frame controls on, and in the de-interlace pulldown select Reverse Telecine.
Compressor automatically detects broken cadence so the process works even with already edited footage. This works for me, as I am often handed footage from the DVX100 shot in 24p (non-advanced) that has already been digitized. I edit the footage in a 29.97 timeline then follow the process that I described above. Cuts down dramatically on waiting time since you are only reverse telecine’ing your edited sequence (not all footage).Only snag is I’m not sure how well it would work with a sequence with heavy effects or motion compositing, Probably not at all. Otherwise, hope this helps,

I should also add that transitions are not as smooth for the obvious reason that you are going from 30fps to 24fps.

Hi Gabriele,
Follow MacGregor’s advice if you have an edited sequence.It seems like he is on to something.
Reversing the pulldown on individual clips edited in a sequence is not recommended. The timecode will change your in and out points and you will have to redo the edit by eye: a thankless task.In previous posts I was referring to 24p clips not advanced 24p.
Reversing the pulldown in Cinema Tools works well but you have find the A frame manually. The auto function does not work. This is time consuming. After Effects (I have CS4) can correctly auto detect the A frame and then you can batch render out in the codec of your choice. This is more efficient: just a few brainless mouse clicks per clip. Could it be scripted I wonder? However, both of these methods pertain to removing the pulldown BEFORE you edit in a 24p sequence, as it should be done.Phil
