not recognizing 24pA cadance in Cinema Tools nor FCP HD
Hey everyone,
I hope someone can shed some light and help me figure this out. I shot a short film using the SDX-900 (DVCPro50) on 24pA mode. I imported using Noah’s method’s and most of the clips worked fine except for few which is due to some timecode breaks. So instead I reimported all the tapes straight as 29.97 so that I can either apply remove advance pulldown from FCP or do a reverse telecine from Cinema Tools. By the way I have done this in the past with footage shot with DVX100. But anyway back to the point usually in Cinema Tools, it will bring up a simple dialogue box that has a header with advanced pulldown on but for some reason the footage that I shot with the SDX900 it keeps coming up as removing 3:2 pulldown and various options for it which I know for a fact is wrong. Although I did do a test just to see if I might have indeed shot it in regular 24P and assumed the advanced. Even though the test footage did indeed work according to Cinema Tools, upon viewing the footage, there is a whole new introduction of interlaced frames – which clearly indicates to me that Cinema tools is trying to remove a 3:2 pulldown when there is not a 3:2 pulldown. I guess what I’m trying to say is, is there a way to force Cinema tools to recognize the file with its proper advance cadance and/or a way of fixing the cadance so that Cinema Tools will be able to recognize it right away? Thanks for any help that you can provide.

Perhaps it was not shot 24pA. This happens. How many interlaced frames do you see in the 29.97 clip. There should be only one every five frames if you shot 24pA. If there’s more it’s 24pN.

Hey Noah,
I’m stepping forward frame by frame and what I count is 4 frames and 1 interlaced, 4f & 1i. So yes, 1 every 5 frames. -
Try recapturing in smaller pieces- TC breaks can throw off the cadence detection.

Unfortunately I won’t be able to recapture it since I don’t have the deck any more. Would I be able to export the footage into segments from let’s say FCP or quicktime? Thanks. If all fails, I’m thinking about exporting each clip into an image sequence and manually removing the redundant frames, renumbering the sequence and opening them back up as 23.98 fps footage. I know it is tedious but frankly I’m running out of cheap options. In which case according to the advanced pulldown scheme, and from looking at the pattern of 4 frames and 1 interlaced, where does A start and D end. Actually can this be done manually?

That would create an incredibly huge amount of work and result in footage that couldn’t be accurately coordinated with the original timecode. I’d highly recommend digging into the budget for another day’s deck rental- depending of course on the projects overall import.

Have you tried “remove advanced pulldown” from the FCP tools menu?

Yes, that was the first thing that I tried. BUt it immediately would give me an error message. From my past experience, when FCP gives me an error when trying to remove the advanced pulldown from the already imported 29.97 clip, Cinema tools is able to remove the advanced pulldown from that same clip. The most interesting part about this whole ordeal is that the imported clips range from 5 minutes long to 30 minutes and many in between. Some of the advice that I have been getting is to reimport them in shorter durations. How short of a duration?
