What do you mean by "flickering"? I've seen people use that word to describe a number of phenomena including judder, flashing, and much more. Is it a jittery horizontal motion? Is it changing opacity?
for example when the text moves horizontaly across the page, a white thin line will quickly flash up horizontally in places across the lettering.
I hope that makes sense!
the opacity is fine too!
What happens if you render it as an AVI or Quicktime? Do those issues still pop up or is it only in the SWF?
If it's fine in an AVI, try encoding that AVI as a SWF and see if that works.
would it be better to try and make it in flash pro?With no doubts
will i pick it up quickly?If you need just to move your text, which is a PNG file(s), it takes for about a couple of minutes to place it on a stage and arrange to taste. Basic principles are exactly the same: stage, objects, motion path...
