A storage and bandwidth calculator for video and audio media files. StorageCalculator is a simple way to calculate the storage and bandwidth required to store your footage. The app contains data on a wide array of professional codecs, including ProRes, XAVC, DNxHR and RedCode. The data rate chooser helps you to estimate the data rate required to fit a video of a certain duration into a file of a certain size - for example creating an MP4 which has to fit onto a pen drive. There is also a copy time estimator, which can be used to estimate the time required to copy data between different drives.

PocketOP turns your iPhone into a broadcast operator's viewfinder. Point it at any location and see two real-time field-of-view brackets on the live camera feed: one for the wide end of a lens, one for the tele end. No mounting hardware. No guesswork. Just point and see whether the lens reaches far enough and goes wide enough. PocketOP is also a fast field reference: search the full database and tap any lens or camera for its complete specifications. See the shot with a live zoom preview Switch from the field-of-view brackets to a live zoom: PocketOP digitally frames what a given lens would see on your camera feed and moves to the sharpest rear lens for you. A fast way to check whether a focal length gives you the shot before you rig anything. Built for broadcast lenses, PTZ cameras, and cine zooms The database covers professional broadcast lenses, PTZ cameras, and cine zoom lenses for Super 35, Full Frame, and Large Format productions. Every entry uses manufacturer-published HFOV values, not focal length conversions. For the full and current database, visit pocketop.app/database. Database updates without App Store review New lenses and cameras land via remote update. Request a missing lens from inside the app and it can appear within days. Fine-tune against real equipment A guided calibration workflow lets you adjust the overlay per lens with live feedback and a +/-25% offset range for parallax compensation. What you get for free Four broadcast lenses (Canon CJ14ex4.3B, Canon HJ40ex14B, Fujinon XA20sx8.5B, Fujinon UA80x9) and one PTZ camera (Panasonic AW-UE40), fully functional with all features. Upgrade to Pro to unlock the complete database with continuous updates. Works best with PocketOP uses your iPhone's rear cameras as a reference viewfinder. iPhones with multiple rear lenses (Ultra Wide, Wide, Telephoto) give you more flexibility when matching broadcast focal lengths. iPhone 14 Pro and newer recommended.
