sub_id

FilenameParts.sub_id

The sub id is the first branch of the identifier.

Notes

The sub identifier allows uppercase words without the underscore [A-Z0-9] with a maximum length of 4.

Its regular expression is ^[0-9A-Z-]{1,4}+$

The sub identifier’s task is to distinguish different states of the same context. A context in this term could be different video captures of the same object with multiple cameras or just different file versions.

The sub identifier should be seen as a branch of the identifier. Not a version within a sequence.

Examples

Multiple different video captures of the same object.

ant#CAM0.avi
ant#CAM1.avi
ant#CAM2.avi

Different children (versions).

a#1
a#1ST
a#2ND
a#RAW

Returns
