hvx 1080p or 1080/24pA pulldown removal
Can anyone help me with a problem I’m having?
Here’s the breakdown:1. I directed a commercial which was shot on the Hvx and firestore fs-100. The dp said he shot in 1080 and 24fps. Also, he had the footage recorded into quiktimes instead of P2.
2. I am editing the footage, and have had some experience with pulldown removals. I imported the footage into the Last version of FCP before the new FCP studio 2, which just came out. The footage was in the 108060i DVC ProHD codec @ 29.97 for the frame rate. There was no option to reverse telecine (2:3 pulldown) the footage in FCP or Cinema Tools. So, I assumed that the Footage was shot using the 1080/24pA mode, which uses the advanced pulldown (2:3:3:2) And sure enough final cut would remove the advance pull down making the footage 23.98 (Cinema Tools, however, had no options)
3. Upon examining the closer 23.98 footage, I noticed a problem. There was still interlacing.
4. I have now compared the original 29.97 footage and the advanced removed 23.98. The 29.97 has three frames of progessive then two interlaced frames. 23.98 has a cadence of three progressive frames, then one interlaced.
Conclusion: The DP nor myself knows whether he shot in the 1080p (24 over 60i) hvx mode or the 1080/24pA mode (24 with advance pulldown over 60i). Do you have any suggestions?

[Really Cool] “The 29.97 has three frames of progessive then two interlaced frames.”
That is a standard 2:3 pulldown. A 24PA (advanced) pulldown has (starting from the A frame) two progressive frames then an interlaced frame then two more progressive frames. If you find the first interlaced frame and start from there, there will be four progressive frames and then one interlaced.
Ways to remove a 2:3 pulldown are either using Cinema Tools, Nattress Plugins or using After Effects.
