FCPX Flow transition is killing me
on Nov 18, 2017 at 5:54:49 pm

About three months ago I needed to use flow. I watched Simon demonstrate MFVX's tool and was impressed so I tried the one in FCPX. EVERYTIME I try to use it I got a beach ball. I chalked it up to my slow RAID.

Now I'm on a brand new Tech 24TB 8 drive RAID and it just happened again!

Anyone else having trouble with this?

It’s usually a very fast process

What kind of machine do you have? Have you contacted mvfx about it?

On what sort of footage- codec/resolution/length. Takes about 4 seconds on my stock MBP.

I was on a 2014 i7 iMac pro then moved to a 2013 Mac Pro 6 core 16 gb ram. Files are Pre res 422.

this is the flow that comes with FCPX. I will buy Simons on Monday, but I cannot figure out why this would be an issue.

Are the clips longer than an hour? What version of OSX & FCPX are you running?

Clues: The timeline is HD 1080 29.97 ,the clips in questions are full 4K 23.97 RED footage. I think I must be hitting a memory ceiling. Only 16GB on the mac pro.

Is there any background activity happening?

Have you tried on a 23.98 timeline first?

Yeah I would definitely boost the memory- 16GB is way low for a Mac Pro.

I have a mid 11 27" iMac with 24 GB of ram. I was trying to use compressor with FCPX still running and it virtually stopped. Now I close FCPX and everything else and compressor cranks along. So I think you are right that it is a memory issue. Turn on the activity monitor and it will indicate how much memory is being used.

I am planning to get a new "loaded" iMac. Should I plan on adding 64 MB of RAM (after market of course)? I expect to be using 4k in the future.

Also consider the best graphics card you can get.

Imacs (i7); Canon 5D Mark III/70D, Panasonic HPX250P, FCP X 10.3, teach video production in L.A.

iMac Pro is supposed to drop any day now- might want to wait a bit.

Hi there!

I am experiencing the same issue.
I don't think it's the computer, I think it's some kind of bug in FCPX with R3D footage.
First, I thought it was freezing because of the external storage unit, my footage was on.
But after moving the whole thing, I started digging and found your thread.
I am working on an iMac Pro, 128gb RAM, 18 cores and the best graphics card, so I'm pretty sure it is not a hardware related problem.
I also work with 4K R3D footage, trying to put on the Flow transition.
When I changed the view to proxy, it worked just fine, but I really want to export in full quality.
The Apple customer service was no help at all, for he did not even know what R3D footage was...
I hope someone will fix this issue.

Sorry to open this back up, but I thought maybe it is of interest for you guys.
Or maybe you came up with a solution?

Regards,

Benjamin

optical flow can become corrupted sadly. i had this several times on different machines. optical flow would completely stop working and any speed adjustment (or flow transition for that matter) would either be not rendered and just apply frame blending or end up in "beach-balling".

i could only solve it by creating a new, fresh user account and work in fcpX from there – or go through a complete clean install of the system (no repair, no upgrade, a "format c:" process). after that it was all peachy.
