What kind of footage are you going to edit with what application? If you use iMove and use a consumer camcorder, the laptop will do fine and all you have to do is wait for iMovie to import the footage (due to transcoding it to an editable format).

And please do not be fooled by the product photo, as it shows a MacBook Pro with Retina Display while the specs list a standard or classic MBP.
 
Definitely, LB96.

Unless you are a video professional and will be editing all day, in which case a quad-core processor would speed things up and make you more productive.
But if you just intend to edit and upload the odd video, that particular MacBook pro will be absolutely fine for years to come.

Greetings from Catalonia.
 
My only concern is that the picture is of a retina Macbook, and the computer is a regular Macbook, no retina. Some confusion there.
