Final Cut Pro 10.4.7 on Mojave.

I imported a 44 hour project from imovie to FCP. In iMovie (latest version for Mojave), the timeline clock shows 43:50:xx.
When I import to FCP, the FCP timeline shows 19:50:xx. It goes up to 23:59:59 then starts back at 0:00:00, and climbs back up to 19:50:xx, instead of going from 0:00:00 to 43:50:xx. The problem is when I export the file, it shows 19:50:xx to export and then only exports the first 19:50:xx of the whole project. It appears to be a limitation of 24 hours for a project but iMovie does not have this limitation.

I really need to export this using FCP.
All help appreciated!!!!

I know not exactly ideal, but just an idea to get your project exported in the meantime. You could use FCP to export out the video in 2 or 3 parts, and then use iMovie or another software to stitch them back together and reexport as a full video.

Then simply export it as a ProRes file. ProRes LT is more than enough. Then you can use iMovie (if it in fact doesn't have that limitation, which I find hard to believe) or whatever to then output it to whatever codec you were thinking of using. Of course, that PRLT file in HD and 30fps will be just under 2TB in size! And even a decent H.264 is going to run you around 1TB!

But then exporting as H.264 AND reexporting as H.264 after stitching won't even make for a perceptible difference in quality. But if you insist on not reencoding, if just for time reasons (44hrs is just BONKERS) then you could go with "Lossless Cut"… for example.

All applications have size limitations of one type or another. For example, Photoshop is 2GB.

Color me curious; What subject needs 44hrs of continuous video?

I think he may be expanding on the themes so expertly captured in the 10hr long 2016 Classic "Paint Drying"
Obviously, to fully explore the themes and create a truly profound experience, a much longer runtime is inevitable.
Personally, I can't wait to see more in this vein - "Planks Warping" is obviously long overdue, and we simply must have "Steel Rusting".

I just have to ask:
Who is going to WATCH a continuous video for 44 hours?

In other words, why not "break it" into 2 or more segments...?
