Precisely. I was hiding that complication of "industry standard" square pixels (396/395 for NTSC) versus true square pixels. While scaling from computer graphics, I personally use 648x486 true square pixel frames, scale by 79/72 (11/10 times 395/396 = 79/72) to 711x486 and then crop/pad to 720x480. But I wont dare mention that in public..! Selva ------------------------------------------------------- This SF.NET email is sponsored by: eBay Great deals on office technology -- on eBay now!
