A note on Apple's Tech Info Library warns that QuickTime 4.1 is incompatible with Final Cut Pro 1.0.
The warning reads: “QuickTime 4.1 introduces newer DV device control-software that may not work with Final Cut Pro 1.0 or 1.0.1. You must upgrade to Final Cut Pro 1.2 in order to use QuickTime 4.1. This is a free upgrade.”
No copies of Final Cut Pro 4.0 where sold in the UK. Users of 4.1 or earlier can benefit from the free upgrade. Final Cut Pro costs £705 in the UK.
