MetaMaster: Beyond the EXIF

Welcome to the world beyond the basic EXIF! With MetaMaster you can discover much more than simple photo and video information. 

EXIF metadata
—————————
MetaMaster supports multiple metadata sections such as EXIF, EXIF auxiliary, TIFF, IPTC, GPS and more. The metadata is sorted by sections for easy navigation. You can also select which sections to show in the viewer and editor for each media type, such as photo, video or Live Photo.

Video metadata
—————————
Apart from reading QuickTime metadata, MetaMaster also extracts additional information about video and audio files, such as video bit rate, frame rate, audio bit rate and more. Unlike many other EXIF viewers, MetaMaster correctly recognises slow motion videos and their frame rate. 

EXIF editor
—————————
MetaMaster allows to modify the EXIF data of photos*, videos and Live Photos. You can modify orientation (photos only), date and time, location and much more. Edited Live Photos remain as such when saved to the camera roll. Animated GIFs preserve all their frames and you can also change the loop count.

Individual resources
—————————
Did you know that a photo or a video on your iOS device is not always a single file? They are assets, that sometimes contain multiple resources. For example, when you edit a photo, its edited copy is saved alongside the original one. With MetaMaster you can access all these resources, inspect their metadata and even extract them into a separate asset. No need to revert your edits just to retrieve the original copy of your photo or video anymore.

Depth masks
—————————
Photos captured in portrait mode contain depth masks alongside the colour image. MetaMaster can access these masks, inspect their metadata (yes, they also have metadata!) and extract them into a separate asset. You can use these masks for creative editing techniques, like double exposure.
