MOV export problem at DVinfo.net

Matthew Pugerude · October 30th, 2007, 10:35 AM

I am having trouble with exporting an Aspect HD project to an MOV. The problem is that it only comes out as a 4:3 file not a 16:9 file. When I play it back in QuickTime it looks really bad and squished. The same happens when I export a Cineform MOV file as well. What am I doing wrong is it an encoding setting or a player setting? Please help

Sounds like a pixel aspect ratio issue, so the image data is correct but is presented without the 1440 to 1920 expand. The MOV export is primarily the production file for post tools that doesn't support AVI or AVIs deeper than 8-bit, such as compositing tools (and Macs) which don't care much about pixel aspect, as it can be controlled within the application. Still is sounds like minor bug.

Russell, My final target was SD. So my work around was this; I exported a quicktime h.264 file with the aspect ratio 853 X 480 with SQUARE pixels. This played just fine for me. IF you need HD I would just export a 1920 x 1080 square pixel file. You should not be limited to the aspect HD 1440 X 1080 frame. That is all I have for you.

update ..sorted it!
This may save somone some hassell to get a 2:35.1 H.264 QT file, like the apple trailers.

In Premier Export movie to file type >quicktime
In video tab, compressor=H.264 >fame size=1920x1080 >square pixels
Export.
Open the file in Quicktime select >file>export>movie to quicktime file
click the options button, click settings, compression type H.264
click on size button> dimensions select custom
1920x816
Preserve aspect ratio using crop

cheers Russ
