If it’s a newer camera, no. FCP 7 was discontinued 6 years ago…no updates have been made. Meanwhile, the AVCHD format is always updated, and every camera uses a different variant. So FCP won’t be able to interface with that camera directly. nor MXF. If you want to continue using FCP 7, you’ll need to look at third party converters to convert the footage, like EditReady.
