Yes, but you could run out of resourcs, if you have many overly-large Still Images. That will depend on your computer, and on your setup.
Thanks for the information.
I'll give it a try.
In relation to a post that you answered earlier about PAR, I just discovered that Adobe Photoshop will let you change the aspect ratio of the pixels in any image. I've used Photo Shop for years and never knew this.
At least it makes it clear as to what happens when you change it.
You can change from 1 to 1.333 and see it happen.
The PAR adjustment was added to Image>Pixel Aspect Ratio as of CS, when non-square pixel support was added. This was to allow one to work in Video and especially with Encore Menus.
Note that when working with images, with non-square pixels, when Opened, one gets an information message saying, "Pixel asptect ration correctionis for preview purposes only. Turn if off for maximum image qualtiy."
Good luck, and happy editing,
