Magnification, effective aperture and light loss for extension tubes; new close-focus distance for diopters.
Anamorphic
Desqueezed aspect ratio and horizontal-equivalent spherical focal length for any squeeze.
Data/DIT
3 calculatorsData & Storage
Solve for file size, record time or bitrate, from codec presets or a camera's published data rates.
Upload Time
Estimate how long a file takes to upload, with a best-to-worst-case range.
Storage/RAID
Compare usable capacity and fault tolerance across RAID 0, 1, 5, 6 and 10 for your drives.
Editorial
6 calculatorsAspect Ratio
Pixel dimensions for any aspect ratio, anamorphic desqueeze, and fit or fill to a delivery size.
Speed Change
Playback speed and running-time change when footage plays at a different frame rate.
Target Length

Simple/effective app
"Constantly pulling out my calculator app to do this type of work and googling for answers. Nice to have a well designed calculator with all the info in my pocket, especially if I'm shooting off grid with no cell service."
Truly Amazing
"This is an insanely helpful tool for anyone working with motion capture or post-production. The app has zero fat, is cleanly laid out and has a range of tools I knew I needed (and a few I didn't know I couldn't live without)."
Top Notch
"This app is a must have for Filmmakers. Simple, intuitive design, with essential tools for industry professionals. I used it every day on set last week. Highly recommend!"
Thank you !!!

Great tool
"Great and simple tool so you can leave cross multiplication behind you. Lots of key basics, excited to see what else is added!"
