Need help: relink 60fps footage failed

So when we tried to update the project from 10.0.5 to 10.1.4, all the 1080p@30p footage are relinked, while the 720p@60p are still missing, says incompatible file. Tried many ways to make FCPX believe the footage are the same, but none worked properly.
Is there a trick to make them relink? Thanks in advance.

Hey Jack,

Updating from 10.0.5 to 10.1.4 is indeed a HUGE jump. Try relinking the 720p files one by one. Does that work?

Hi Ronny,
Thx for the advice, but it doesn't work. The only that works so far is re-import all the incompatible footage, and try to replace all the unlinked clips on the timeline. Sounds a bit complicated, but we don't have a better way.

Yes that seems indeed the only solution that is left. As I said: 10.0.5 to 10.1.4 is a HUGE jump. Many things have changed under the hood between these versions, including the way FCP X handles 60p video. That may be the reason why it won't recognize nor relink the files anymore.
