HDMV In Out effects another question

[paulemasters]

Hello:

From what I have read in various places, it appears that each 'frame' / step of an effect takes up image buffer space.

That is, if I have an image, say 10x100 = 1000 pixels and there are 5 effects steps that move it on the screen, whether it be in the same place or across the screen, it will take up 5000 pixels in the buffer even though it is the same image. Is that correct?

It makes since in some ways and not in others.

I would like to know as the programs I use don't give an image buffer usage for HDMV menus like Designer or Scenarist.

Thanks for any help.

If you use the same image you can crop/move it to create multiple effects but the buffer will remain still. The buffer increase if, for every effect, you use different files (or if you use multiple files in your composition object, in that case the buffer will increase at the beginning when you use the files for the first time). If on the same image you change position or crop values (probably also the palette), you are actually doing modifications on the same file so the buffer will not increase. Hope this helps.
