black frames between cuts
Hi,
I’m editing an HDV movie shot the Panasonic P2. I’ve been editing in 720p60 and have output my files to DVD a few times now. Everything is perfect!
Today I converted my files to 1080p24 & have gone from 4:3 to 16:9
I just output the DVD now & popped it in the player and now there is 1 black frame at every cut point, so everytime we cut from one shot to another there is 1 black frame between shots.
Does anyone have any idea what this is? did it happen because I switched formats?
I really have no idea what’s going on & Any help will be greatly appreciated – if i need to give more info on this problem let me know.

Hi Mike,
I realise this post is almost a year old, but … I am having the same problem and am wondering whether you figured out what was causing the black frame between cuts when you output?
My timeline and footage is NTSC but I am outputting to PAL. I reckon the problem is something to do with the change of frame rates? But no idea how to prevent it.
Any ideas?

And a further 2 years (almost!) on… i am having the same problem.
In my case i’m going from a 1080p film scan (some at 18fps, some at 24fps) to PAL output and it seems to be resulting in two black frames at every cut.
Did anyone stumble upon a solution/reason?
I’ll be trying to sort this out until it works, so will post my results in case any other FCP-newcomers like myself run into this.
Cheers, M

Hey,
I have had the problem again since then … this time PAL to PAL so it’s not to do with frame rate. The commonality both times was a change in format – so I reckon that’s the culprit as suggested earlier in the thread … still no idea how to correct it. To take it further, I actually think it may have something to do with interlaced footage? As both times I encountered this problem, it was from footage from DVDs (and another guy on this thread had problems with HD interlaced footage from an HDi camera …
I managed to fix it by literally duplicating frames at each cut – and then applying a compression marker to each frame around the cut, so that each of those frames around the cut could not be compressed (or interlaced) when outputting to a quicktime movie or whatever (remember when outputting to make sure you select “include all markers” or whatever that pulldown menu says. This was a very long way around the problem, and I’m sure there’s a WAY better solution … but no-one responded to my thread, so that was what I did.
Best of luck!

Hi Lara,
I went ahead and did a whole bunch of exports using different settings, taking various notes. I found that exporting as Photo-jpeg had perfect results. I’m still not sure why though! I have quite a few more of these little projects to do going from HD scanned super 8 film out to dvd, so it’ll be interesting to see if this happens every time. I will have to give your method a shot next time. Thanks for the tip!

I have the same problem with FCP #7. I have tried exporting Pro Rez, DVCPRO HD & SD for files and get these erratic black frames. I see other people have the same problems. Have you found a fix ? Thank you for your time, Nick – contact@misterphoton.com

Hi,
I stopped having this problem after i began converting everything to ProRes 422 before doing any editing. I’m not sure if this is why the problem went away, but it only ever happened with super 8 footage that had been scanned in HD with some open source codec that FCP didn’t seem to fully understand. Once i started converting to 422 straight away… no more black frames!
Hope that’s of some use.
Cheers
