Issues Digitizing 24P Advanced

[Michael Sacci]

Couple of things, your seq preset has nothing to do with the capture, they need to be the same time base and codec to work together but if you change your seq settings it does nothing to the capture.

That preset should work but double check a couple of things

The FPS should be 29.97 w/ the Remove Adv Pulldown Checked

Then the captured footage should have a frame rate of 23.98.

In your above statement is the good capture coming in at 29.97? If so can you step through the frames and set the pulldown frames?
If this footage is 29.97 try the Adv Pulldown Removal under the Tools menu.

Try capturing a small clip, just a couple of seconds (after the camera has started to record a shot but before it stopped) with the adv. pulldown removal setting and see if that works.

Also, its very important when shooting in 24pa to hit “rec check” on the dvx if the camera has gone into standby mode after you stop recording so the record head is advanced to a usable timecode (or when the camera has been paused a while in general). Otherwise you might have to capture clips that don’t include multiple starts and stops.

Also, using capture now can give you the error you are reporting, are you using that or logging individual clips?

Hi Thanks for responding.

Yes, this is the setting I used. When the footage digitizes properly, it comes in at 23.98 as you mentioned.

The problem is that most of the footage will not digitize properly because of the message I keep getting, something like “Break in Pulldown Cadence detected” (original post tell the exact message). This message causes capture to stop. I have the option to Abort or Continue. If I choose continue, when the tape gets to the same place as before, I get the same message, I start all over again, and the clip never gets digitized. This happens at many points on many tapes.

I tried your suggestion of digitizing at 29.97, without Advanced Pulldown removal, then removing it through the Tools Advanced Pulldown removal. But when I do this, again I get the same message “Break in Pulldown Cadence detected,” and the clip is not modified to 23.97.

So it seems the settings are right, it’s just the Break in Pulldown Cadence thing. Do you know what this message means or what to do to fix it?

Thanks again.

Hi, thanks for responding.

Yes it works to capture just a small clip at 29.97 with Advanced Pulldown removal, and the footage comes in at 23.98 as expected. All is well. But the problem is I keep running into the message “Break in Advanced Pulldown Cadence detected,” and clips won’t capture.

Thanks for the info about Rec Check. Problem is with some of the tapes, it was all one shot for 60 minutes, so I’m assuming then that wouldn’t be the problem.

I’m not using Capture Now, I’m logging clips individually.

Do you know what this message means and what to do about it?

Thanks again…

Natress has a cadence filter that may shed some light on your problem, it is one of his free filters. Run it on the footage captured at 29.97. see if there is a change at the problem spot.

I’ve seen this problem with the situations I described, but not with one clip. It gives you the message on all the tapes? Did you reuse tapes or use low quality tapes? Are you using the same camera you shot on to capture? What kind of drive are you capturing to?

In any case you could still edit the material on a 29.97, though unless you have some other material that’s already at 23.98. It will look essentially the same.

Hi Gery,
It gives the message at many points on many tapes. Don’t know if it’s every single one, but it’s so many that it is making digitizing agonizingly slow. I did not reuse tapes, I used new master tapes Panasonic AY-DVM83MQ.

Also, though stopping and starting the shot perhaps is an issue in some instances, it’s not always: right now I’m capturing footage from a performance that is 63 minutes in ONE LONG TAKE. I didn’t start or stop the camera once and I still have the identical message “Breaks in pulldown cadence”. Which is why I thought it might be a problem with my FCP digitizing settings…Also because other small clips on this tape I tried capturing and there is no start/stop and I still receive the message…

[Norman]

PS Even now that I’m just trying to capture it normally without Advanced Pulldown, it’s still reading one clip as two and giving the “Dropframe media detected” message, splitting the long take into two shorter clips.

[Gerry Curtis]

Sounds like you’re going to have to work around the problem then unfortnately. Hopefully it’s not the camera, but this is one of the reasons not to use 83 minute tapes if possible.

[Bill Bilowit]

So true, logging and capture is the way to go for so many reasons.

But in cases with one enormously long camera take with no stops, I’ve logged anyway- dividing the massive take into smaller clips at spots with a rough camera move that would likely be deleted anyway. If the shot is a clean lock-off, you can still break it up, with 15-second or so overlaps to cover wherever edit points may be.
