Thanks for that correction. The QT7 Pro "Open Image Sequence" command included the ability to save it as a reference movie, so I wrongly assumed that restoring this feature in Catalina QT10 also included that. But it appears to only include the ability to encode an image sequence as a regular video file.

The QT7 reference movie feature was nice and fast on the creation side, but without transcoding it was generally quite slow within FCPX. So I would often end up transcoding it anyway.

Here is an old link that supposedly has PHP code to produce a Quicktime reference file: https://www.phpclasses.org/package/1946-PHP-Generate-Quicktime-Reference-Mo...

The original Quicktime format specification included a provision for reference movies consisting mostly of pointers to external sources. I assume that was implemented via the Quicktime framework which has now been taken over by AV Foundation: https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QT...

See "Reference Movies" on page 81 of the ver. 1 Quicktime File Format Spec:
https://developer.apple.com/standards/qtff-2001.pdf

Using reference movies via AV Foundation was mentioned in this 2015 WWDC talk, so it must still be possible (in some fashion) from an API standpoint: https://developer.apple.com/videos/play/wwdc2015/506/
