6.3.3. Timecode range fields
The following timecode range fields allow the initiator to play only a specific range of the selected input
files. If only a start time is specified, the media file(s) will play from that start time until end of file. If only an
end time is specified, the media file(s) will play from begin of file up to and including the specified end
time. When several input files are involved, it is possible to define individual timecode ranges for each of
the files.
field name field
type
value description since
tc-start optional hh:mm:ss:ff
timecode string in
timecode format of
media file
The timecode of the first frame of the range to be
played. This start time applies to all input files, unless
overruled by a dedicated fileN
-tc-start or fileN-rtc-start field.
If not specified, playback will start with the first valid
frame found in the file.
tc-end optional hh:mm:ss:ff
timecode string in
timecode format of
media file
The timecode of the last frame of the range to be
played. That is, this time is inclusive.
This end time applies to all input files, unless overruled
by a dedicated fileN-tc-end
or fileN-rtc-end field.
If not specified, playback will continue up to and
including the last valid frame found in the file.
fileN-tc-
start
optional hh:mm:ss:ff
timecode string in
timecode format of
media file
Similar to the tc-start field, but only applies to the
media file defined with the associated fileN field. N
is in the range [0, ...].
For example, if a complex source string defines a clip
comprised of three media files, it is possible to define
an individual tc-start time for the last input file with
something like tc-start=00:11:00:00; file2-
tc-start=00:10:42:00;

fileN-tc-
end
optional hh:mm:ss:ff
timecode string in
timecode format of
media file
Similar to the tc-end field, but only applies to the
media file defined with the associated fileN field. N is
in the range [0, ...].
See fileN-tc-start for an example.
