The 3ality metadata file format looks like this (sample line):

TC:05:45:54:08:02 F:004.83 I:004.62 Z:007.80 A:000.91 C:010.28

Note that line 1 of the file will be imported onto frame 1 in 3DE4 (see script "Import 3ality Metadata"), all existing lines in the file will be imported onto the following (sub)frames.

SIP2 metadata packets are fixed-length 61 bytes ASCII strings represented as follows:

Example:

TC:12:41:37:11:03 F:003.71 I:003.80 Z:008.69 A:002.46 C:008.36

This would mean:

Time: 12 hours, 41 minutes, 37 seconds (early afternoon)
Frame: 11, 3rd Metadata packet within frame
Focus: 3.71 feet
Iris: 3.80 T- stops
Zoom: 8.69 mm
Interaxial Distance: 2.46 inch
Convergence Distance: 8.36 feet
