HDV1080i50 and DVCPRO HD 720p60 in one sequence?!
Hi
I am editing with HDV 1080i50 footage and DVCPRO HD 720p60 footage. So far I have been editing each format in different sequences however now is the time to put all the footage into one master sequence to complete the documentary I am cutting.
I’m having lots of trouble with all the footage staying in sync in the same sequence.
The only way I can get the DVCPRO HD 720p60 footage to play in sync is if the sequence settings are set to exactly that – 720p60. But with the sequence settings set to this, the HDV1080i50 footage slips out of sync slightly and can appear jumpy.
If I flip it around and put the DVCPRO HD 70p60 footage into a 1080i50 sequence – that causes the DVCPRO HD footage to become even more jumpy and out of sync.
I would’ve assumed that FCP allows for the differences in frame rates and finds a setting automatically to accommodate all
If anyone knows the of the best sequence settings for all of this footage to sit happily in, please let me know.
Cheers
Ed

Wow…you have a couple of problems. First off, you are mixing frame sizes. This might be OK for offline editing, but when you online, you need to have everything as one standard frame size.
Then you are mixing codec types…GOP (intra-frame) vs Full Frame (inter-frame) formats.
And that brings us to the biggest problem…mixed FRAME RATES. You can cut offline with mixed formats, but they must be the same frame rate in order to work properly. And now only are you mixing frame rates, but you are also mixing STANDARDS. You are mixing PAL and NTSC…that never works. Even if you had two NTSC frame rates, say 23.98 and 59.94…you’d need to convert one frame rate to the other before you start editing.
So what you needed to do before you started editing was conformed all of one footage type to the other. Converted the PAL to NTSC or the other way around…depending on what your delivery masters need to be. And while you were converting the frame rates, it would have been easy to convert to a common format as well.
But now? After the fact? Not sure if the Nattress Standards converter will help here…because again, you still have the issue of frame size difference and codec type difference.
Man..this is a mess. If it was a simple frame rate conversion, say 59.94 to 29.97 or 23.98…that would be manageable. Because the audio would stay the same. But 50 to 60? There is a 4% difference in audio.
No…for me to sit and figure this out is billable. Hope that someone else has done this and can share insight. I am chiming in to say that you did everything wrong, and how to do it right next time. Convert everything to the same format BEFORE you edit. Especially when mixing PAL and NTSC and different frame sizes and formats.

What Shane said. You can’t mix PAL (1080i/50) and NTSC (720/60) in the same timeline.
You need to send one set of your footage to a post house like PostWorks in New York and get the footage converted to match the other footage. PostWorks is where we send all our HD Standards material that needs to be converted.

Thanks Shane and Walter that’s cleared things up for me – I will be doing this conversion at a similar post house in London.
