In FCP 6.0.4, in a sequence set to a Pixel Aspect Ratio of NTSC-CCIR 601/DV (720x480), and a Frame size of 720x486 (CCIR 602 NTSC 40:27), the output image info says it has a pixelAspect of 0.444444. When the input is a 720x486 clip listed as Pixel Aspect NTSC-CCIR 601 in the browser, its imageInfo says it has a pixelAspect of 0.395062. The same input frame fetched via the temporal API using getBitmap:layerOffsetX:layerOffsetY:requestInfo:fromParm:atTime: reports a pixelAspect of 0.444444. At least getInputBitmap:withInfo:atTime: shows that same frame with a pixelAspect of 0.395062, the same as the regular input. Why does getBitmap:layerOffsetX:layerOffsetY:requestInfo:fromParm:atTime: produce a different pixelAspect than the other two methods? Is there any way to tell what the *real* pixel aspect of that frame? Interestingly, when I set the sequence to use square pixels, all the pixelAspects are 0.444444. BTW, 0.444444 is 640/720/2, while I would have expected to see 648/720/2, or 0.45. I don't see where 0.39506 comes from. Anyone know what's going on here? Is there any way to know what the *real* PAR of an image param is? This email sent to site_archiver@lists.apple.com
