I've got a Contour Roam2 which has recorded close to 30 hours of 720p 60fps video saved as .mp4. A large portion of this is setting up the camera, waiting etc, so I need to do simple cropping of the video. After looking through many threads it appears that most editing programs export in 30 or 24fps. However playing through Quicktime 10.0, the unedited 60fps video is far smoother than the 30fps .mp4 file exported through iMovie 11 9.0.4. I have also opened a ~5 second segment into photoshop, which shows 290 or so individual frames. Can someone recommend a good (preferably cheap) program that can crop these videos without losing quality? At the moment I am looking at the student version of Avid, but that's $300AUD.
