Just a follow-up, within Premiere the source file also also shows as 1920×1080 by clicking on the imported clip properties. Interestingly enough, I create a 1920×1080 sequence and imported both that original problematic clip and another clip (captured with a different mobile phone) and the latter shows up as expected, but the original file in question shows up as if it were 1280×720. I can’t explain this, maybe someone else can shed some light on this for me.

Thanks for your replies and also that my aspect ratio of my source file wasn’t 1920×1080 like I thought. After setting up a sequence at 1280×720 I now am able to scale my video without cropping or black bars. I’m still not sure why the file properties in windows show an incorrect aspect ratio for the source file that led me to my initial mistake. Here’s a screencap of the source file properties:

If I can’t rely on this to determine the resolution of my source file what would be the best alternative to do so?
