thanks Aharon. sorry, my question was a bit messy, i’ll make another attempt:

i have two compositions. one high def. in the hight def composition i’ve built a patchwork of small clips side by side. and the second composition that is standard def. i only make a movie out of the standard def comp.

i drag the high def into the standard def. which means i only see a very small section of the high def in the standard def on the screen. like this diagram: https://www.xs4all.nl/~sakalli/diagram/example.gif

(the red rectangles represent the many clips that the high def composition consists of and the black section is what is visible in the standard def.)

then by manipulating position of the high def composition under the standard def composition i create transitions between the individual clips in the patchwork. i only make a movie from this sd composition.

my question: my movie is standard definition but as it uses a section of the underying high def composition, does AE have to render the complete underlying high definition composition frame to calculate the section that constitutes the the standard defitnition frame? and is that an explanation for why rendering this standard definition comp takes so much time?

not sure if i succeded to to make this is any more clear…

thanks for your help in advance.
