FFMPEG users,

I am trying to edit a subclip from a larger movie. I just want a two
minute section.

This is the command I have been working with:

ffmpeg -i input.avi -ss 01:05:16 -t 120 -vcodec copy -acodec copy output.avi

However, instead of getting a two minute (120 second) clip, I get a
clip that starts at the selected time, and runs all the way to the end
of the film (about 45 minutes long).

What is wrong with this command?

How can I get ffmpeg to only output a specific time length of video?

Thank you.
