  Weird Unwanted Change in Aspect Ratio/Size

  Posted by Ralph Chaney on November 29, 2012 at 9:38 pm

  Aspect ratio changes -without my input- when played in Quicktime…!?

  Here’s the deal:

  Working with a 1920×1080 DVCPROHD timeline.

  1. Export, after rendering. (No conversion of any kind)
  2. Shows as 1920×1080 in Finder, and plays as 1920×1080 in Finder (hit space bar)
  3. Plays as 1920×1080 in Final Cut 7.0.3
  4. BUT – when I open and play in Quicktime it plays as 1280×1080
  5. AND – If I send to compressor to convert to “50% of source”, it comes out squeezed to 640×540, same ratio as 1280×1080.

  So:
  Final Cut 7 and the Finder treat it as 1920×1089
  Quicktime and Compressor treat it as 1280×1080

  somebody HELP me! (…voice of Jim Carey in The Mask)

  Thanks!

  Thanks.

  I usually work in ProRes, so thanks for the DVCPROHD 1280 info.
  I used Compressor and got VERY STRANGE – inconsistent results!
  (at least inconsistent with my understanding of how Apple’s video products really work)

  I sent a DVCPROHD test to Compressor from the timeline, and forced it’s setting to 1920×1080.

  In Final Cut: It STILL shows up as 1280×1080, as per bin info.
  In Quicktime: It shows up as 1920×1080, as per Info window.

  Remember – a straight export from the timeline yields a Quicktime-interpreted file of 1280×1080.

  **Perhaps Compressor adds some kind of cueing code that tells Quicktime to see it at 1920×1080?

  Do you know anything about this?

  (The TV station is requesting it in DVCHDProHD 1920×1080, so I’ll use a Compressor 1920×1080 version of the show since Quicktime is interpreting it that way and they want a Quicktime file.)

  Today’s Lesson:
  Learn more about DVCHDPro -and/or- Always use ProRes.
