Trouble Exporting Quicktime Movie - - - - - -

Hi there Kirupa Community,

I have a movie clip loop that i am trying to export as a quicktime movie. i have put the mc on my first keyframe then placed another keyframe at the 5 minute marker so i can export this as a 5 minute loop of this animation. however when i am exporting it i get an error message that says ‘the export failed because there is not enough memory’ I have 4 gigs of ram in my computer and i am checking my system activity when i am doing this export and under 2 gigs are being used. does anyone know why this is happening? i have tried exporting it in every way possible in the export menu; i have even tried exporting it to a folder on an external drive but every time it gets about 3/4 the way through then gives me that error message. what am i missing? i know this must be possible. i need the 5 minute loop to use in final cut for a project i am working on. any help is appreicated much.

thanks,
