I have a simple render consisting of one comp that has 2 jpeg images moving right to left between two keyframes(easy ease). That comp is nested over a .mov of a moving background. When I RAM preview the motion looks fine, but as the images move a rolling line moves from the bottom to the top of the image. However when I render, there is no rolling line but the images sort of stutter across the screen instead of moving nice and smooth.
Background mov was rendered using Apple Pro Res 422 720x486 NTSC D1 - with no field rendering.
I went through and matched my composition settings and final ender settings and I'm getting the results described above.
Your feed back is greatly appretiated.
The rolling line is sync tering. But that's a whole different matter. The rest of your description is quite vague. Could be simple performance issues with uncompressed output, could be the usual issues associated with all image pans/ credit scrolls where you need to obey certain speeds. Please clarify.
