Dropped Frames with P2 media in FCP

[Michael Wilfong]

I just posted this same problem…I cannot figure out how to prevent it. I can’t even figure out why this is happening.

I’m using the same settings in camera and FCP. If you figure this out please email me a solution via michael@studioseven.com

Thanks,
Michael.

I spoke with a rep from Apple and they say this is the only solution known.

[Jason] “When editing in FCP, I keep getting a dropped frame during a cross dissolve on the in-bound shot at the very end of the effect. It’s very noticeable as some of the shots are of fast moving subjects.”

Dropped frames are almost always the result of your drives not being fast enough to move your data-

for 720p60 — the data stream is close to 18 megs a second and most un-powered or internal hard drives are not fast enough to handle that amount of data with out dropping frames.

At 24p ( where the data stream is more like 6 megs a second) the reality is you do not have enough content to cover the transition. Make sure you have at least 1 second before the in point and 1 second after the out to make sure the transition can handle without issue.

You have a contradiction in terms. 720p24N at framerates of 48 and 60 frame rates doesn’t make sense. 24pN is 24 frames a second only. If you recorded 720p 48 over 60 and 60 over 60 you will have to use the Panasonic frame rate converter to get those shots to 720p24 to use in your timeline for the slow motion. The converter is free and downloadable from Panasonic’s site. It also comes with FCP 5.1.

thanks for your help guys…(It’s taken me awhile to respond because I’ve been offline for over a week).

Well, first off, it’s not a drive problem – even a burned DVD of the media shows the same problem – a dropped frame, but ONLY during
a cross dissolve or other transition.

secondly, in response to Jeremy, a frame rate of 48 in a 720/24PN sequence would simply record at 48 frames per second, even tho the file is still 24FPS (overcranking). All the clips play perfectly in slow motion – no frames lost – if I use straight cuts in my sequence, I have no dropped frame issues whatsoever. ONLY when I use a transition do I get a single dropped frame from the INBOUND
shot at the END of the transition (this issue is very specific to these conditions – I haven’t had a problem otherwise).

Regardless, I’m going to look into the fixes for this, especially with FCP 5.1.

If I find a solution, I’ll certainly come back and post.

Thanks again,

Jason

actually, it seems that apple’s “fix” in FCP 5.1 should work, being that it’s an issue that occurs during a RENDERED effect.
