6.3.4. Relative timecode range fields

Similar to the timecode range fields above, but this time with relative timecode values (i.e. relative to start

of file), meaning that the first valid frame produced by the decoder will always be referred to as having

time value 00:00:00:00.

optional hh:mm:ss:ff

timecode string in

timecode format

of media file

Relative timecode of the first frame of the range to be

played. Relative meaning that the first valid video

frame always has time 00:00:00:00.

This start time applies to all input files, unless

overruled by a dedicated

fileN-tc-start

fileN-rtc-start

field.

If not specified, playback will start with the first valid

frame found in the file.

rtc-end

optional

hh:mm:ss:ff

timecode string in

timecode format

of media file

Relative timecode of the last frame of the range to be

played. That is, this time is inclusive. Relative meaning

that the first valid video frame always has time

00:00:00:00.

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.

timecode string in

timecode format

of media file

Similar to the rtc-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 rtc-start time for the last input file with

something like rtc-start=00:11:00:00; file2-

rtc-start=00:10:42:00;

optional

hh:mm:ss:ff

timecode string in

timecode format

of media file

Similar to the

rtc-end

field, but only applies to the

media file defined with the associated

fileN

field. N is

in the range [0, ...].

See fileN-rtc-start for an example.
