mixing cameras and fps workflow
on Feb 12, 2012 at 6:39:45 pm

I'm about to start filming a music video using different cameras and I need to make sure I record using the right settings to get what I want.
I'm shooting with a Sony HVR Z7E, a Canon DSLR 7D and a Gopro.
The Canon 7D and gopro will be used for slowdown recording, underwater and timelapse.

Those are the settings that I think I should be using (Pal)

The Gopro for slow motion to record 1280×720 50fps
Canon 7D for slow motion to record 1280x720 50fps
Sony HDR Z7 to record 1080/25p
To slow down:
all 50fps footage to be slowed down by:
1) Transcode h.264 to prores using mpeg streamclip
2) Conform Prores footage using Cinema Tools
3) Edit conformed video in Final Cut

to transcode all the footage seems a waste of time. should I edit the clips first in FCP as h.264 and then export them to streamclip to transscode to prores?

Once I have all the slowed down footage and normal speed footage ready to edit in FCP, I will have 2 different sizes of footage 1280x720 (canon and go pro) and the bigger ones from the HDR Z7 which will be 1440x1080 (i think). So, what is best: to set up the sequence settings as 1280x720 and scale down the 1440x1080 or to setup the sequence to 1440x1080 and scale up the 1280x720.

can I edit a 24 fps shoot on a 25fps sequence?
I'm also concerned about some footage been interlace and other progressive, will that create problems?

Thank you

[jordi robert] "to transcode all the footage seems a waste of time. should I edit the clips first in FCP as h.264 and then export them to streamclip to transscode to prores?"

It isn't a waste of time. FCP doesn't edit h.264 files. It CAN, but not well. Sluggishness...exporting wrong (audio not in sync, not including all of the video). You MUST transcode H.264 to ProRes before you do any editing in FCP.

[jordi robert] "can I edit a 24 fps shoot on a 25fps sequence?"

Not well. One frame will get repeated every second, and it will look weird.

Thanks shane.
Is there a "right way" bring the footage into streamclip? I mean, should I first Log and transfer to FCP and then send to streamclip, or can I just transfer the clips from the Memory card to streamclip?

Once I have all the clips transcoded to Prores ready to edit in FCP, I will have 2 different clip sizes:1280x720 and 1440x1080 (i think). So, what is best: to set up the sequence settings as 1280x720 and shrink the 1440x1080 or to setup the sequence to 1440x1080 and blow up the 1280x720?


Thank you

Log and Transfer...if you download the Canon EOS Log and Transfer plugin, FCP will then do this for you. As long as the card structure is intact. If not, use Streamclip. Bring the H.264 files into Streamclip, and render out as ProRes.

Use a 1920x1080 ProRes sequence. The footage will size properly to fit.

"Use a 1920x1080 ProRes sequence. The footage will size properly to fit."

Really? how is that? if I bring a clip 1280x720 to a 1920x1080 sequence, I'm sure the clip wont fill the canvas, logic says that it will be smaller.

Really appreciate your time Shane.

FCP scales them to fit. The 1280x720 will be like 166% or something. And FCP stretches out anamorphic formats like 1440x1080 to fit.
