FCPX : insane computer slowdown when rendering on maxed 2015 MacBook retina – normal ?

[Bret Williams]

In your HUE example, did you create your filter from scratch in Motion, or did you duplicate the one in FCP X? Sounds like you were trying to recreate what they did from scratch.

The filters in X that aren’t native and can be opened in Motion obviously exist somewhere or they wouldn’t be able to magically create a duplicate Motion project from thin air.

Nope. I used exactly what exists in Motion. I took the existing parameters and published them. There are actually some other threads around here confirming this change in color science.

Why not “duplicate and open in Motion”? If that functioned differently then you’d prove your case in a matter of seconds.

One other note from your article. You may have realized it now, but you mentioned that to change the order of which published items appear in the inspector you have to unpublished and republish. Not true. Just drag them up or down in the project pane under published parameters. You can rename and drag items up and down in the list. This is essentially where you’re building the interface for X. If you’d rather a published parameter be at the top, just drag it up there.

Thanks for the tip.

After a little testing last night, I discovered that the hue/sat effect is still a motion template, but that your’re correct that it definitely uses different color science. But I think it’s just a different filter. You can copy and paste their filter in Motion and create your own hue/sat filter that will be exactly the same. You can even add it to your favorites too if you like the X version better. Seems to me that the X version of the filter was tweaked to stay within certain limits. Blacks won’t drop under 0 and the Luna is more limited than Motion’s filter. Motion’s filter quickly goes way out of broadcast safe limits.

Thanks again for everyone’s replies on this .

Something else or note, which probably makes my issues with computer slowdown more obvious. I often work with multiple “layers” with some clips overlaying each other on the time line. So in some cases there may be the equivalent of two “story lines” with their own effects being rendered together.

Still, I noticed when I am rendering a file that is not as large as 1920 x 1280 my computer runs fine, but once I’m rendering at 1080 it slows down to almost unusable .

Does anything help this, like, for example, using an external drive for the project file ? What about proxy files ? I have always been a bit confused how that works as whenever I get into that my clips disappear.

Thank you again !!

What you’re seeing is mainly related to the slower CPU speed and lower performance Nvidia GPU on the rMBP. I have Thunderbolt attached RAID-0 SSDs as my working environment (over 800MB/sec sustainable I/O) and my rMBP still does this (and it’s also a fully loaded i7 unit).

For now, get yourself a good coffee maker and enjoy a fresh cup any time your need to render effects / transitions / etc. …
