Timeline frame rate and exposure correction capabilities of the latest iMovie
My background. I have been trying to create movies made from clips that can be played back at 60 fps. I have been using a Nikon V1 camera for creating video clips. It records 1080 HD movies that are interlaced, but at 59.94 fps (Double NTSC) rather than the 60i standard of 29.98 fps (Standard NTSC). It also records 720p60 footage as well. I would like to maintain the temporal resolution of footage (the "video look") I get with the camera as well as perform good exposure and color correction on dark/underexposed footage. I currently use iMovie '09 and Final Cut Express 4. My current computer runs on Snow Leopard, but I cannot update to Mavericks or Yosemite that the latest versions of iMovie or Final Cut Pro require. I intend to upgrade my computer in the next few months, but what I get will depend on what video editing software I figure I will need. Hard tech specs regarding this version of iMovie, however, are hard to come by. I am hoping someone with experience using the latest version of iMovie can help answer a couple of questions.
Regarding timeline frame rate - right now both iMovie '09 and FCE 4 destroy the "video look" I want by forcing the frame rate to go down to 30 fps in the timeline. Does the current version of iMovie support a true 60 fps in the timeline? Playing with the software and provided skateboarding footage at a local Apple Store indicates it does. And does it handle interlaced footage? Also, can it handle 24 fps footage (which another camera of mine records at) actually at 24 fps?
With regards to exposure and color correction, I find iMovie '09's capabilities lacklustre. If a clip needs better correction than iMovie can deliver, I import the clip into FCE 4 and either use the "Color Corrector" filter along with highlight and midtone exposure sliders to improve the exposure, or Gamma correction along with some hue adjustments. Can iMovie adjust midtones, highlights, and shadows separately, or do Gamma correction, or does it just do basic exposure and contrast correction?
Would I be better off considering using Final Cut Pro X instead of iMovie.
