QT displaying at 655×480
Good Morning!
I did a quick search and saw that someone asked this same question a few months ago, but never really got a satisfying resolution.
My basic info.
OS 10.5.8
FCP 7.0.1
QuickTime Pro 7.6.4FCP Sequence Settings:
Frame Size = 720×480 (NTSC DV 3:2)
Pixel Aspect Ratio = NTSC – CCIR 601/DV (720×480)
Not Anamorphic
Compressor = Apple ProRes422(HQ)Exporting a QuickTime Movie (not using QuickTime Conversion)
quick side note:
Does anyone else find these 2 export options mildly confusing/irritating? I understand the distinction between the two, but c’mon! What was wrong with “Export Final Cut Pro Movie”?
/side noteWhen I open this export with QuickTime, the Movie Inspector (cmd-i) tells me the clip is being displayed at 655×480. I took a frame grab using Snapz-Pro which confirms that it is actually displaying at 655×480.
To take the tests a step further, I used one of the generators in FCP to create a circle on my 720×480 timeline. In FCP it displays as a perfect circle. Using the same steps to export, I opened the circle footage in QT and it appears slightly wider in the middle. Again, using Snapsz-Pro, I took a frame grab of the QT displayed circle and opened it in Photoshop. Photoshop confirms the 655×480 display size. In Photoshop I created a circle and layed it over the top of my FCP generated circle. The top and bottoms match up, but the FCP generated circle is slightly wider than the Photoshop circle.
I know that QT has to do some math to convert the Pixel Aspect Ratio from non-square NTSC pixels to square pixels, but it seems to be misinterpreting something. In the past, my 720×480 non-square pixel exports always displayed at 640×480 and looked fine.
Is there something wrong with my FCP settings, or is this a QT bug?
Sorry for the epic post.
Happy Holidays!

Here is one thing I have found. I am still looking into the SAME issue, and frankly its irritating that it is even an option to mess with aspect ratios. Try this:
In quicktime, under WINDOW/Show Movie Properties
Click on the “Presentation” box and set to Conform Aperture to “Classic”
This will fix it, however I think you have to do it for EACH video. Annoying. If you have found answers since, please send them my way.

I tried to use the ‘presentation to classic’ option and its not changing the dimensions – is there something I missed?

Stumbled upon this and had to figure out how to properly export from Final Cut Pro (without any re-rendering) while displaying as 720×480 in QT. Right click on your sequence, choose “settings”. Make sure your resolution is set to 720×480, Aspect DV 3:2, and pixel Aspect Ratio set to “Square.” The pixel aspect ratio is what did it for me. As far as the Anamorphic 16:9 box, leave it unchecked if you would like the image to be displayed as squeezed in QT (this was a requirement for my delivery). If you check it, QT will display the video in the un-squeezed 16:9 aspect ratio when playing back.
