The video in my timeline is 720 by 480 (1.2121). When I clip on "Export Frame" in the program window it exports a jpg that is 720 by 480 (0.9091)
I know I can right click on it and "modify - Interpret footage" and correct the pixel aspect ratio.
My question is "Why is it doing this and how can I correct it"?
Is their a setting I'm missing? Why does it change the pixel aspect ratio?
