Everything you need to know about every camera worth using. "How much drive space will I need for this Alexa 35 shoot?” "What's the dynamic range of the Venice 2?” “How long will these batteries last me on a Komodo?” "How big is this file going to be when I export?” If you've ever asked these questions, this is the app for you. Whether you’re making decisions on set, troubleshooting in an edit bay, or figuring out which camera to buy, CameraKit has you covered. Search over 200 cameras with a list that includes Arri, Canon, Red, Sony, Blackmagic, Panasonic and more. All specs and data sourced by hand: no AI means no hallucinations. SPECS Includes dynamic range, sensor size, native ISO, lens mounts, resolutions, video outputs, maximum FPS and a link to the manufacturer's website for firmware & manuals. STORAGE Determine how much footage you can fit on your camera card or hard drive-- or how much storage space you'll need for a given recording time.  TRANSFER Predict just how long it will take to move your files, whether you’re transferring to a drive or over the internet.  POWER Estimate how long your batteries will last, or how many you'll need for a shoot, with the option to factor in accessories like your monitor or wireless transmitter. SENSOR See the sensor size for the current resolution and compare sensors between cameras. COMPATIBILITY See how well each camera and format performs with the latest versions of Final Cut Pro, Premiere Pro, Avid Media Composer, Assimilate Scratch and DaVinci Resolve. Also see if it's been approved by Netflix for original programming. AND MORE Jot down observations and anything you want to remember about a camera with Notes. Compare specs or any other tool like Storage or Compatibility. Calculate film footage for 8mm, 16mm, 35mm and 65mm cameras. Save your calculations and return to them later with a tap. Mark any camera as a favorite for quick access.

It has every single piece of information for nearly every single camera on the market today. Comparing recording formats between cameras has never been easier." -Shane Hurlbut, ASC • Support • For support, send me an email at zak@grayhourmedia.com or message me on Instagram @_zakray.
