Thanks Paul. Actually, I capture and encode all of my content at no more
than 15fps, so I suppose that the inverse telecine
settings would have no noticeable effect.
As far as the resize filter is concerned, .. I already have it set to high
quality, ... yet I'm stll not pleased with the results.
When I capture directly through realproducer at 176x132 (without doing any
additional resizing), for example, .. in most cases the
aliasing effect is horrible. Do you think that when encoding directly to
realvideo I would get better looking results if I was to
capture at 320x240, ... yet simultaneously resize to 176x132? Or would
there not be any difference?
thanks

Inverse Telecine does make a distinct difference because it removes
unnecessary frames and can spend more bits on the real frames. However, the
filter is not used (even when the option is checked) when your input is
less than 30 fps or your maximum framerate in the Target Audience Settings
are less than 30 fps. Perhaps this is causing some confusion in situations
where the filter isn't being used and therefore the results don't look any
different.

Use the High Quality Resize filter to improve the scaling quality. This is
found in the Preferences dialog on the Video Filters tab. The default is
Fast Resize.
