Encode only a few frames to test

I want to encode some video, but I just want a few minutes of it to test. Is there an option to limit the frames to convert? My input video does not have chapters and is over 2 hours long.
Thank you,

I have not seen any options that can do that. Are there any alternate titles on the same disk that you can test with that would help?
Ex:
-t 4

In SVN code use --stop-at-duraton, which accepts seconds as its unit, or --stop-at-pts, which accepts presentation timestamps as its unit (90,000 ticks per second).
Will get around to a --stop-at-frame function someday, but I'd really prefer to do it right and have them all be one option with two arguments, like:
--stop-at duration:90
or
--stop-at frame:1000
or
--stop-at pts:900000
...and I haven't had a chance yet.
