video frame size

[hank]

I'm having a bit of a problem determining the funtional behaviour of the avclip.AutoSize fscommand in relation to avclip.DisplaySize.

My main question is: what exactly is AutoSize supposed to do?
I would think it sets the size of the videoclip on the resolution the clip was originaly encoded on, but it looks like it depends on the framesize the clip was before setting AutoSize = TRUE. (framesize was set with DisplaySize). Problem is I cannot find out any logic in the size I wind up with.


original clip size 320x240
swf size: 800 x 600

if (fas.avclip.DisplaySize , DoubleSize)
(--> clip scales up to appr. 640x480)
then
(fas.avclip.AutoSize, TRUE) --> does nothing

if (fas.avclip.DisplaySize , OneHalfScreen)
(--> clip scales up)
then
(fas.avclip.AutoSize, TRUE) --> gets even bigger!!! (appr 10%)

if (fas.avclip.DisplaySize , HalfScreen)
(--> clip scales down to appr. 160x120)
then
(fas.avclip.AutoSize, TRUE) --> changes position, NOT framesize!

Second, what do all the DisplaySize arguments mean exactly? Are to relative values compared to the swf it is used in or absolute to screensize or video size...
