Q: I need to open a fcpx v10.1 in fcpx v10.0.8

What are you trying to accomplish?

Russ

Assuming they have a computer running on Mavericks they can download the latest FCP X 10.1.1 and use that.

Got it now.

If the project was originally created in 10.1, I can't think of any way this could work without the client updating to 10.1…unless they have Final Cut Pro 7. There possibly may be a path from 10.1 to FCP7 using Xto7 and then back to 10.9 via 7toX. But I'm not at all  sure about this – whether the third party apps will be compatible with different versions – and I would definitely check with the developer before buying. (Perhaps someone else on these boards would know.)

Russ

Good question, but I'm afraid not. To open the XML you would need a version that was the same as the one that created it.

Could they make do with importing the flattened video as a clip?

Russ

Yes.

Clearly, it's not ideal. (Some things, like titles, will be very difficult to modify if baked in.) But they could make a variety of alterations with any of the edit tools – swapping out content or adding content, for example – possibly some basic color grading and effects – and certainly reformatting. Maybe half a loaf, but better than nothing if they're staying with 10.0.8.
