  Outputting the correct aspect Ratio 16×9 HELP 1440×1080=1920×1080???

  Posted by Tom Lee on February 24, 2009 at 5:38 am

  I’ve captured HDV 108060i footage into my project at 720p30 using the Apple ProRes 422 Compression. I then captured SD NTSC shot by someone else at 16×9 (or wide as some consumer cameras call it) in to my project at DV NTSC CCIR 601 using media manager to recompress with Apple ProRes 422 . I intended to place the SD footage in the sequence and conform the HD clips down to it to have full frame footage through-out (No pillars or bars) . After placing the clips I ultimately had to zoom in to all of them to conform to a 16×9 frame.

  Now when I export using compressor I cannot for the life of me get a final output with a 16×9 ratio. It seems to always, no matter what I change, come out as 720×480 with no pixel aspect correction. I have to open the clip in Quicktime and change the aspect ratio by typing it in after compression.

  Please somebody explain this square, rectangle, 1440×1080 is 1920×1080 corrected confusing mumboJumbo. I understand my Canon XH A1 at 1080160 produces a 1440x 1080 frame, after that, bringing it into FCP and out again, I’m lost. FCP doesn’t seem to reference 1440×1080 anywhere in the program. Why even tell me about 1440×1080, and not just make it 1920×1080. Just do the math back in some Mac closet and make everything standard. Did I mention I also regularly have to pull in AVCHD from my Sony HDR SR11. It has its own set of problems. Where can I learn somebody. please. Thannx.

  HELP

  What settings are you using in compressor? In compressor, you can manually set the frame size in the geometry subsection of the inspector panel. With square pixels, 640×360 or 853×480 will be 16×9.

  I would stick with square pixels. HDV uses a rectangular pixel (.75×1) that quicktime is interpreting as square (1×1) and distorting.

  There’s a pretty good explanation of pixel aspect ratios here:
