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
