Weird Unwanted Change in Aspect Ratio/Size
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 1280×1080somebody 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.-R.
