I just received a PNG sequence in 720x540 and i need to send it to someone, uncompressed 10-bit 720x486 ntsc (4:3), any idea how to do that without changing the image??
When you load that into FCP it will look like it should. 720x540 are square pixels (1.0 ratio), but DV is slightly retangular (0.9 ratio). So those images loaded into FCP should render out in their desired look on a NTSC timeline.
