Thanks for your responses!
I don’t want to make a letterbox flash file. What we were doing was in the 3:2 sequence, making the 16:19 footage fullsize so it fills the frame, essentially cropping off the edges.
If I output my sequence full size, how do i compress it in flash as 4:3 without distorting my image? The final output has to be 4:3 and I have no say in that. Is this possible?
I’m also working with a lot of photoshop graphics which is another problem of sizing and cropping and distorting.
