[FFmpeg-user] itsoffset vs. setpts=PTS+10/TB

[Jonathan Baecker]

Hello everybody,
can somebody tell me, that the input parameter "-itsoffset" is technical 
equal to the filter  setpts=PTS+seconds/TB?

And when not, is there a filter with that I can add an offset to the 
input. The background is, that I use a split filter:

    [in]split[out1][out2]


and I want to use the both output to overlay them on different time over 
a video clip.

Regards!

Jonathan
