Please use the free MediaInfo and post a screenshot of the properties of your media in tree view:

Many users are having issues with VFR. If the file is variable frame rate, use Handbrake to convert to constant frame rate before importing into Premiere Pro:

Here is a tutorial:

Shutter Encoder may also be used to convert to Constant Frame Rate:

From your screenshot it looks like you need a 960x540 sequence. (currently it is 540x960)

Click on the timeline and the go up to Sequence Settings and make that change...
