I don’t, no.
Created a new project, added a tonne of different media to it; ProRes 1080p, ProRes 4k, AVCHD, Red 4K, 6K, 8K, DJI drone. Didn’t use proxy workflow, added optical flow and speed ramps to a mix of different clips; no issues. It must be something to do with proxies.

Exactly the same, Mac Pro 2013 6 core, 64GB d700s. Media is all stored on a fast thunderbolt 2 raid

Maybe it’s a Mac Pro 2013 thing? We’ve got virtually the same spec machine with libraries on an external raid right?

Exactly how stable my project is when I switch from proxy to original files. Starts analysing optical flow, 0% stays forever and if you quit the analysis it crashes the app. Final resort for this project was an xml to resolve after manually collapsing all multicam segments and switching off all custom transitions and titles. Then export clip by clip from resolve and rebuild the project in fcpx to add the titles. Terrible.
Anything with optical flow or speed adjustments with high resolution I can’t go to fcpx anymore until the bug is fixed

Ask the original creator of the project whether they used proxies, and if the optical flow was used on the proxy? I know you might not need to use proxy workflow but it might be a weird bug with that workflow

That’s great experienced advice thank you jeremy. I’m guessing you export from redcine x Into a separate folder but use the same file name as the r3d to ensure easy re-linking?
I usually work on the r3d files so I hope that the optical flow issues are only linked to the proxy/original workflow in fcpx.

Should also add, fcpx becomes completely unresponsive and crashes if I cancel the optical flow analysis.

Totally the same. Switch the project from proxy to original media, a rendering bar appears in tasks which starts, but a process appears for optical flow analysis. This stays at 0% even if I leave the project open overnight. I’ve trashed preferences, deleted cache, deleted analysis files for the whole library, updated fcpx to most recent version, uninstalled and re-installed and it still happens with this library. Starting fresh doesn’t help as this is a 12 min short for a huge corporate client that has been worked on for 6 months.
Macpro2013, 6 core, 64GB, D700, media on gtech studio xl via thunderbolt 2. Media is mixed red helium 8K, red dragon 6k, a7s h264, a7s timelapse avi and dji drone and all of this is stored on the t2 raid. Plenty of spare space – 28TB. All audio files are either mp3, was or embedded with the red files. Optical flow was used on the proxy files of the dji footage only, not the red raw. Project is set at 3840×2160 25p.
I’ve worked on fcpx for years and love it – it has its faults but I really want to find the answer as if it re-occurs it means I will have to manually create 6 and 8K prores 4444 files before creating the library and abandon the proxy workflow…lots of encode time and double size storage space required. I’ve seen a few people on YouTube finding issues with optical flow and their approaches have made no difference. Only thing I haven’t done is export an extended xml and rebuild the project inside a new library….

Sounds exactly the same as my experience with this project. I think the proxy workflow with optical flow has a bug when being taken back to original media which corrupts the library file and the project.

So you need to add 5.97 frames to each second before your final export? I’d suggest trying frame interpolation with Davinci resolve
