  Compressing HD to SD from Final Cut to Compressor

  Posted by Jessica Mathies on August 20, 2010 at 9:26 pm

  I shot some HD footage (1080i) for a client,and they want me to deliver all the videos in 720×480 format – there’s no getting out of this. For the life of me, I can’t compress the edited files without it looking squished. I’ve read the forums, and have seen the bit about not using a squared pixel aspect ratio. I’ve tried other pixel aspect ratios, but still no luck. Can anyone help me, please? My settings are below. Also, if there is a thread that can tell me how to compress 1920x1080i to 780×480 using only FCP and Compressor, that will work too. I couldn’t find it.

  Sequence settings:
  Frame Size: 1920×1080
  Aspect Ratio: HDTV 1080i (16×9)
  Pixel Aspect Ratio: Square
  Anamorphic: No
  Field Dominance: Upper / odd
  FPS: 29.97
  Compressor: Apple ProRes 422

  Export Settings in Quicktime Movie: (I export to quicktime movie so that I can export as a reference file)
  Compression: H.264
  Quality: Best
  Frame Rate: 29.97
  Key Frame Rate: 24
  Frame Recording: yes
  Encoding Mode: Multi-pass
  Dimensions: 557×313 (current)

  QUESTIONS:
  Under Dimensions, should I switch from “current” to “compressor native”? If so, which setting should I use, and do I check the letterbox option?

  Should I export with QuickTime Conversion instead of QuickTime Movie?

  Compressor Settings:
  In inspector under the Geometry tab, I’ve tried the following aspect ratios w/ a frame size of 720×480:
  Default for Size
  HDV 1080i (16:9)
  NTSC CCIR 601 / DV (16:9)
