FCPX renders green frames

The length of your render makes me think possibly you have an issue with your footage. I had a similar flicker and tearing of the video so I first began to diagnose the problem by adding the effects each one at a time to see if it was reporducable, and it was. The work-around I listed before was also not working. It was then I realized that one of the still photos I was using was VERY LARGE, approximately 8K (which also caused the renders to be very slow). Once I resized the photo down to a managable size, the effects rendered without the flickering and tearing.

well it's not 8K stills, but all my footage is 5K 😉

it's just magic bullet looks. turn that off and it works fine, even with other effects like beauty box which take a long time to process too. They've promised an update. But yeah, whatevs. All my footage is fine.

i'm getting a new graphics card (GTX 680) to help speed up the renders as FCPX likes a fast GPU

Follow Larry Jordan in his tutorial and it works100% because the acuracy of the extended clip is important, also use PLACEHOLDER instead of CUSTOM

This worked for me.

Never had any green problems on my under-powered MacMini.-

Until now … 😮

I made a few tests with my latest toy (a new cam, Pana hcv707).

Noticed the well-known flaw, if you have AVCHD and mp4/iFrame on same media, the AVCHD isn't recognized (me stupid, I did know!)

Made a manual re-wrapping of .mts (ReWrap2m4v)

Made a manual conversion of .mts (Adapter)

=>

both result in green-flickering clips! (well, seconds of green!)

Proxies from this files show dramatic artefacting!

Optimised show almost green only!

Importing straight from SDcard (…after erasing the iFrame part …), all well - no green flicker. Proxies ok, Optimised smooth 'n easy, 1080/50p fully functional on a 2.26Mac via usb2 connected drive 😁

soooo, my actual advice:

use FCPX as intended

avoid any 'manual' conversion/transcoding/re-wrapping.-

(I dare to assume, that the for most 3rd party apps underlying ffmpg-architecture has 'issues')

does anyone use the commercial product ClipWrap to transcode to proRes?

Any greens there?

Not doing any of that. Keeping it simple... But unplugging my two secondary displays during rendering fixed the problem.

Hi. I speak spanish and it's hadr for me to understand how u solved the problem. Can you please explain to me how u fixed the green frame problem? I'm having the same issue and I'm so frustrated

Please tell me how u did it 🙂 thank you I hope you can help me

How do you unplug the two secondary displays during rendering?? which menu??

I have Final Cut Pro X version 10.0.9 and I just started having this problem today when i imported a file that was an .mov, and then it did the same with a .mp4 file. The green frames and twitchy video started once the rendering would start. I tried several different things, but the only thing that worked was reimporting the video and checking the box under TRANSCODING that says "Create proxy media". This fixed the problem, no green frames, no twitching. 😀

This probably won;t solve your problem. You'll have to switch back to original media before you export, and the problem might recur. You may need to optimize as well.
