Indexing
Overview
This feature does not work in DEMO MODE or if a MXF file is less than 70000 frames. ‘Indexing’ will only work in
LICENSED mode when a MXF file is over 70000 frames in duration. This change was made to cut down on unnecessary
Index files that were created when
‘Indexing’ is enabled.
Setting up Indexing can lead to a more productive workflow when using Calibrated{Q} MXF Import for OSX with very very
large XDCAM-based MXF and other types of Indexed MXF files.
Because of the Long-GOP structure of MPEG2 MXF Files and the fact that MPEG2 MXF Files are not technically limited
to a 4GB file size, it can take a bit more time to build the Index that QuickTime requires when Calibrated{Q} MXF Import is
used with MPEG2 and other types of Indexed MXF Files. This can led to slower load times when a FCP project is opened
using Calibrated{Q} MXF Import with very large Indexed MXF files.
Indexing is a way to take advantage of the fact that Calibrated{Q} MXF Import can auto-create a QuickTime Reference
Movie when a user opens a MXF file in an application to use as an Index file. Once this QuickTime Reference Movie is
created, Calibrated{Q} MXF Import can be setup to search for that QuickTime Reference Movie whenever that same MXF
file is opened again
– and then instead of re-parsing the MXF file it uses the saved file index in its matching QuickTime
Reference Movie. Thus eliminating the need to re-parse large Indexed MXF Files every time they are opened.
The best part about Indexing
is you don’t have to manage QuickTime Reference Movies at all – the Calibrated{Q} MXF
Import plugin does that for you. If a QuickTime Reference Movie is not found it’s simply recreated and used next time the
MXF clip is opened.
Please note that since the created Indexed files are based on QT Reference MOV files so you must not move the Index
files.
