Yeah, I have to e-mail frames with different looks to the editor, so QT files would be too big. I'll just send them squeezed stills if there's no workaround. Thanks.
I have never found a work around. I set up an 'action' in Photoshop that corrects aspect ratio-ness. It is very simple to do and that way, the computer does the annoying work for you (very fast).
I don't think you're getting it. Here's a step-by-step recipe:
1. Choose your frame in the timeline by parking your playhead there,
and hitting the i and o keys.
2. From the File menu, choose "Export Using QuickTime Conversion"
3. When the Save dialog appears, use the Format menu to choose
"Still Image"
4. Next to the Format menu, click the options button and choose your
still image format. A 1280x720 tif will be about 3.5MB. A 1280x720 jpeg
will be about 96KB if you use medium quality. You don't even have to
do anything about the aspect ratio. QuickTime does it for you.
