Keywords include:
- #smpte_df# - SMPTE drop-frame timecode of the frame
- #smpte_ndf# - SMPTE non-drop-frame timecode of the frame
- #timecode# - same as #smpte_df#
- #frame# - frame number of the frame
- #filedate# - modification date of the file (GMT)
- #localfiledate# - modification date of the file (local)
- #localtime# - current system date and time
- #resource# - resource of the producer that produced the frame
Timecode keywords are based on the framerate and position of the frame.
Time-based keywords can include a strftime format string to customize the
output as long as you put some delimiter except “#” between the keyword
and the format string and the keyword comes first. For example,
“#localtime %I:%M:%S %p#” shows only the time in 12-hour format.
Keywords may also be any frame property (e.g. #meta.media.0.codec.frame_rate#)
The # may be escaped with “\”.
