#movie quality
Sam,
Grainy output could be coming from several places.
1) the video compressor you're using is likely the largest culpret. Many
of them compress video by discarding individual pixel's values to create
blocks of the same color which compress better.
The cinepak and indeo encoders (at their highest quality settings) are
no where near as chunky as the microsoft compressors.
2) chunky results could occur if you render your output at a very small
size and then display the resulting small images with a zoomed up display
setting. The standard video player can be set to default to a zoom by 2,
for example.
3) chunky movement (which might be described as chunky results) can occur
when you disable the anti-aliasing routines from the Render Options dialog.
Make sure all those check boxes in the lower left of the dialog are checked
(on).
4) and the last source of grainy output which comes immediately to mind is,
of course, grainy input. Something else to mention…if your A roll image is
say 320 by 240, and your B roll image is smaller, like 120 by 80 or 160 by 120
then it will be scaled up to match the A roll. Like in case 2) above, when
scaling up, it is possible for things to look more grainy.
