I have a 1440 x 1080 AVCHD (.mts format) clip that I'm trying to edit and export with Premiere Elements 8. I'm just trying to get something of smaller filesize like wmv or mpg it doesn't really matter. However, the final production always has a letterbox. If I do 1.33 pixel ratio (making it 16:9 format) it letterboxes the TOP, BOTTOM, AND SIDES. If I choose 1.0 pixel ratio (making it 4:3 format) it just letterboxes the top and bottom. So obviously this is a widescreen clip, but how can I produce it without letterboxes?
Welcome to the forum.
What is the Frame Size that you are choosing in Export?
Your AVCHD material should be Square Pixels, so PAR = 1.0 should be the best, but you will need to choose a setting that matches the Aspect Ratio of your footage.
I'm pretty sure the the pixels are 1.33 because I've been able export in other programs with the following results: 1.0 pixels yields a 4:3 aspect ratio that looks squished and 1.33 pixels yields a 16:9 ratio that looks correct.
With Premiere, I've tried the following settings:
Some others I can't remember at the moment. The widescreen settings letterbox both top and bottom, so again, I'm pretty sure that's the right dimension.
