Found this after some hunting !

there is a work around for that…
what you need is to make ae think that your footage is longer than it is. to do that you need to ‘loop’ your footage in the interpret footage settings… select your footage in your project window, right-click it or file>interpret footage>main…
in the interpret footage menu, near the bottom, is a loop number, set it to the number of loops that will make your footage long enough, in your case ‘2’ (you may also need to pull your out point of that clip to match the new length if it is already in a comp).
