Assisted Editing released a plugin in the App store that converts FCP X projects to FCP 7 sequences.
Xto7 for Final Cut Pro ($49.99), previously named Project Xto7, translates the FCP X Project XML (fcpxml) and converts it for import into Final Cut Pro 7. You can also go directly to Color, Soundtrack Pro, and to other Final Cut Pro 7 XML workflow programs, as well as to Adobe Premiere Pro (and thus to After Effects via dynamic link).
For a full explanation of the capabilities of Xto7 for Final Cut Pro, go to Assisted Editing’s website and download the product documentation. (Assisted Editing is the joint venture of Phillip Hodgetts and Gregory Clarke.)
From Assisted Editing’s Xto7 Support Resources:
To use Xto7
- In FCP X, select the project you want to send to FCP 7 in the Project Library. (Do not open the timeline—just select the project in the Project Library. (If you have Final Cut Pro X and Final Cut Pro 7 installed on different Macs or partitions, make sure the Project and its referenced Events are on an external storage device.)
- Choose the File menu and select Export XML…, and name and save the FCPXML file. (If Final Cut Pro X and Final Cut Pro 7 are installed on different Macs or partitions, save the FCPXML file to the Project’s external storage device.)
- To translate the Project to a Final Cut Pro 7 sequence, either:
- Run Xto7 for Final Cut Pro and use the open dialog to locate your exported FCPXML file (the open dialog allows you to select more than one FCPXML file);
- Drag-and-drop the FCPXML file onto the Xto7 for Final Cut Pro application icon;
- Right-click on the FCPXML file in Finder and choose Open With > Xto7 for Final Cut Pro from the contextual menu.
- A progress bar appears. When finished, you will be asked if you want to Send to Final Cut Pro 7 or Save Sequence XML. Choose Send to Final Cut Pro 7 and click OK.
- Final Cut Pro 7 will launch and display an Import XML… dialog.
- Use the Destination popup menu to choose whether to create a new project or add the sequence to an open project
- If the Sequence Settings popup menu is set to (auto) the sequence will use the Audio Channels, Audio Sample Rate and Render Format of the Final Cut Pro X project; or you can choose your own setting for the new sequence (this can be changed later)
- Turn on the Reconnect to Media Files, Include Markers and Include Audio/Video Effects checkboxes
- Click OK to import the new sequence.
