Exporting 16:9 Quicktimes
I have a 16:9 DV project file that I tried to export as Sorenson3-encoded Quicktime. In the Quicktime settings, I set it to 360×240 with 1.1212 aspect ratio. I figured this would do the trick, but trying it in Quicktime Player scrunched it to 4:3.
I know it’s possible to make a native 16:9 file with Sorenson from having downloaded all those Sorenson-encoded Star Wars trailers over the years.. But what am I doing wrong?

I don’t think you can unless your talking about a matted 16:9
vs anamorphic 16:9.I’ve done this before in other apps though.
You have to put the 16:9 material in a 4:3 workspace
and crop it, then export it.unless its matted then you just export it out cropped but
16:9 matted is the same as putting it in a 4:3.same outcome anyways.

I don’t really understand your context of ‘matted’ or ‘cropping’ in these cases. What I shot is native 16:9 footage. So that means the same resolution as 4:3 NTSC (720×480) but the horizontal pixels are just stretched out to a 1.212 aspect ratio.
I want to make a Quicktime file that shows that 16:9 aspect ratio on the screen when you play it with Quicktime player.. with no extra letterboxed black bars top and bottom, like the movie trailers do.
Finally what I did was had it render with a 1.0 aspect ratio, but gave it a custom size of 436×240 — which, on a square pixel aspect display, will be 16:9 in dimensions. The only thing that sucks, is that this creates extra horizontal pixels that presumably have to take up space in the overall file size.
But is this what the movie trailer people do? Is this what you were suggesting?

Here’s an answer from Rob Lohman at a different location:
Greg: the project settings should be widescreen 16:9 in PAL or
NTSC. Don’t change that!When exporting QuickTime go to custom and then video tab.
Make sure frame size is set to custom frame size and set the
vertical to normal (which will be 480 pixels for NTSC or 576 for
PAL) or a lower value (which you usually want if you want to
put it up on the web!), usually 50%.Then use then multiply the horizontal resolution (720 for both
PAL & NTSC) with the pixel aspect ratio number in the project
settings (which is 1.2121 for NTSC and 1.4568 for PAL 16:9).This should be either 872 (NTSC) or 1048 (PAL). If you are using
a lower resolution take the same percentage out of the horizontal
resolution as well (usually again 50%).Make sure the pixel aspect ratio on this screen is set to 1.0
This should get you a widescreen movie.
