Choppy Playback From GH4 footage
I’m used to solely editing footage from a 5D. It never gave me many issues save for the occasional stutter after I had layered effects/text/etc… I got a GH4 and a GoPro… all hell has broken loose on my non-tech savvy brain. (it should be noted as exposition that I was actually intended to be born about 214 years ago which would have put me coming of age during the prime of Mountain Men in the western U.S. and I would have been able to excel… unfortunately God is perfect but the angel in charge of babies is not and he left me in a vault WAAAAY past my intended birth date. He remembered sometime in early 1984… So here I am as a videographer. Oops)
Anyway, I ran the GH4 clips through mpeg stream clip for ProRes 422 conversion. Was that right or stupid?
Where I am having the most trouble is GH4 clips shot at 1080/60. The timeline hates them.
All sequence settings/clip settings seem to match..I have two WD Cloud Drives. Two WD Passports. One WD portable passport.
Pretend I am a technical idiot (thats “technical idiot” not “technically an idiot”) and walk me through a ground up set up. Including hard drives. Which I should be working off of (Yeah I know, a RAID a RAID, but thats not what I have so go off of what I have)… where capture scratch should be. And workflow for getting this footage in correctly. My head may explode soon. Thanks in advance.

P.S. If it takes you being brutally mean to give me clarity…I’m so fine with that.

Right…
[Jake Reeves] “Where I am having the most trouble is GH4 clips shot at 1080/60. The timeline hates them. “
FCP 7 isnt designed for 1080p60. FCP is designed for broadcast formats, and DVD formats. 1080p60 is neither. The frame rate at that frame size isn’t a deliverable anywhere. Web doesn’t do it, TV doesn’t, BluRay doesn’t. The data rate for that is HUGE. You also need better hard drives than Firewire 800, or USB. eSATA…internal secondary SATA…Thunderbolt. A RAID even better. That’s a lot of data to try to play back. That’s one reason it isn’t a standard. 720p60 is…but the frame size is smaller, so the data rate equals that of 1080i60 (that runs at 30fps.
But the main reason is that FCP and 1080p60 don’t really match. That and you need a very fast RAID to deal with the footage.
[Jake Reeves] “I have two WD Cloud Drives. Two WD Passports. One WD portable passport. “
Those aren’t good enough for this footage. Not one bit. You need Something like this:

or this…(via eSATA)
https://eshop.macsales.com/shop/firewire/usb/raid_1/Gmax
RAIDED drives with a fast connection. ProRes 1080p60 is a HUGE data rate. Way too much for the drives you have.
[Jake Reeves] “(Yeah I know, a RAID a RAID, but thats not what I have so go off of what I have)”
Then you need to get one. I hope you have Thunderbolt connectors, because that’s the best option.
But MPEG STREAMCLIP is fine.
Why shoot 1080p60? You can’t deliver that format? Why not shoot something you can deliver? Unless you mean to slow down that footage to be ultra slow at 1080p30. In which case, you need to do that before you edit too. so it’s 1080p30.

Shane thanks for being thorough. I did convert the footage to 24 in Streamclip. It was shot at 60. Converted to/for 24 in Streamclip.

WAIT…WHAT? No no no no no. Do not convert the frame rate in MPEG STREAMCLIP. No no no. I’ll wager that’s why it’s choppy. Don’t do that. Don’t even in FCP. If you want 23.98, shoot 23.98. Why are you shooting 60p if you want 24p? No…you have to edit at 1080p60. Removing frames that way doesn’t work right.

Oh geez. Shane can you email me at ghostsingray@gmail.com?

Sorry…I don’t do one on one unless it’s consulting, and that I charge for. I like keeping things here so that people can benefit from the advice given. You aren’t the only one doing what you did…just so you know. Others who might do this in the future would benefit from finding this in a google search.

Fair enough. So, lets say I have a timeline/project that is predominately 24p footage but I have several shots from a GH4 that I shot in 60 and am using for slow motion. How do I incorporate those into that timeline?

First, convert them to ProRes 422, as 1080p60, with MPEG STREAMCLIP. Then, use CINEMA TOOLS to conform the footage to 23.98…like I show in this tutorial:

Ok. I just skipped Cinema Tools. I did it in my head… I guess there isn’t really a way to convert to 24 in Streamclip, at least not where I see, but in my head, I had done that. So now I need to take them through Cinema Tools and into FCP.

You feel pretty good about the OWC Thunderbay 4TB?
We are talkin’ weddings and small commercial projects, some small narratives. -
Yup…I took one for a test drive. Even weddings can have lots of footage, and if you are shooting 1080p60, space can fill up fast. And I love RAID 5 protection.
