PDF2MP4 suggestions

Would it be Possible to change the PDF2MP4 app in a way that makes it Possible to just type in the duration in Seconds instead of having to select from a Dropdown?
Same for the Resolution, id like to use the App with the reception screen package, but that results in a slightly stretched image, because of the scroller at the bottom


Both setting a custom resolution as well as duration is now implemented.

thanks for the quick implementation
