FCPX glitchy renders — causes, severity, workarounds?

[Walter Soyka]

Not between Ae and FCP7/FCPX! Feature request…

I know you were teasing, but this wouldn’t be a case for DL anyway. Rigging/publishing and DL are totally different.

No, I’m saying between Pr/UltraKey for foregrounds with a templatized Ae for bg.

no exactly the one – I’ve just got swiss cheese memory.

I’ve written speculatively about the rigging being a friend to branding deployment, without really knowing what I’m talking about, you just could sort of see it –

but from what you said above it requires you to expose too many rigging options? What were you going for? Type Colour Graphic element options?

interesting to hear.

Gotcha. That would work fine, except the graphics aren’t just backgrounds. There will be separate foreground graphics (carrying both branding and content) that will need to animate on and off, and that’s what I’m looking to rig and publish.

I really need to spend some more quality time with it before I can say. This was my first impression, but I may be able to work around it.

[Aindreas Gallagher] “What were you going for? Type Colour Graphic element options?”

Yes. A set of branded lower thirds, backdrops, and a couple other graphic elements — all of which are available in multiple palettes, and all of which can continuously animate on, animate subtly during their “steady” state, and animate off.

[Aindreas Gallagher] “interesting to hear.”

I will follow up as the project continues.

Back on the original subject of this thread – I got the first green frame glitchy renders today that I’ve seen. These are on clips without any third party filters at all, only FCPX color correction, and a couple under FCPX standard titles.

I’ve been using the iMac internal drive (to see how it handles the load) and a Graid firewire drive. Today I received an 8TB Thunderbolt Graid, and hooked up and copied over the events & projects due today, and worked on them, then exported them to vimeo, both rendered and unrendered.

That’s when the green flash frames (2 in one project, 4 in another) started showing up. The 2 that appeared and alerted me to the problem were on a video that was unrendered on the timeline and rendered on export and upload.

The variable is the Thunderbolt Graid (and I also updated Coremelt SliceX today to their new version, but was only using it on a couple of clips in the 4-glitch project, and thats not where the glitches occurred. Had I seen the issue before I would have waited on the update.)

So, no issue before the TB drive. For full disclosure I have the TB drive copying much material over from the firewire drive in the background, and maybe that has *something* to do with this, but still. Never saw this before today.

Dropping an unaffected adjustment layer over the offending glitchy section almost always forces a rerender and fixes it.

This is all on the latest FCPX and new 27″ iMac, maxed out.

Best,
John

I always feel vaguely dissatisfied replying to myself …

Anyway, about the glitches, I think I know the cause. I was copying all the data on the 4 TB firewire Graid onto my new 8 TB Thunderbolt drive. Apparently that does something somewhere that just strains the resources and causes the green glitches. I’ve been editing much of today using the new drive (it IS blazingly fast) and no glitches at all. No problems with plugins or anything else. Maybe this tidbit will help someone else.

Best,
John

Thanks for posting that, it’s always useful to know why things have gone wrong
