How to fit an image to the resolution of video create with Premiere pro?

Question

As the question asked, how to make an image fit to the resolution of the video created?
That the resolution of the Image I used is 720x480, and the video project I created is also the resolution of 720x480, and I wonder why the video I exported contains column.
I am using Adobe Premiere Pro, and what option should I set to prevent this?

Answer 1

The overall size of the image doesn't have as much to do with the size of the file as does the dpi setting.
In other words a 720X480 at 75 dpi could give a file size of 361k
Wereas you could have the exact same size 720X480 at 600dpi and it would give you a file size of 65meg
So as you see the larger dpi will actually dictate the actual file size not the size of the photo alone.

So when you resize a photo you must change the resolution to a smaller number like 75 to make the image workable in some cases, depending on what you are doing and what you are using it for.
