OK . . . I am a long time wedding photographer just getting into video. I shot a concert (not for pay!) with my Nikon D7000 and D300. The D7000 was used to shoot the entire stage while the I handheld tighter shots with the D300. It looks like the D7000 was shooting 1080 and the D300 740 resolutions. When I cut the clips together in Premiere CS6 (30 day trial) no matter how I export the finished video, the clip from the D300 shows smaller when it comes in.

How can I upsize the 740 clips or downsize the 1080 clips so that the output is even . . .

Thanks for any help . . . sorry if I didn't do a good job of explaining myself!
