Hi Neil,

me again :-)

720p means p for progressive frames -> full frames

720i means i for interlaced frames -> 2 half frames
one with even lines and one with odd lines,
then merged to one frame.

TV for example uses interlaced frames
where even and odd lines must be rendered.
This can give much better results for panning cameras
but if you need progressive frames the answer is the
same as before: motion blur.

And don't forget to set the Alpha Channel, if you need it,
under the "Rendering Settings->Properties->Ray Tracing Tab +- Channels"
for Anti Alias, too ;-)
(Compare the results....)

  Subject: Movie - Panning across verticals.


  Hi List,


  When panning passed a set of vertical edges I get a shudder result in the AVI 
- HDV, 720P.


  I will try various ideas to solve it. I will try a higher AA setting, a much 
slower pan rate and "scaling". And maybe "interlacing" or something but I dont 
know anything about that. 


  But maybe someone already has a better answer?


  The AA and the "scaling" will damage render times I think. A slower pan seems 
most promising to me. 


  Thanks
