Originally created to extract the display orientation of Quicktime videos typically taken on iPhones and iPads in a browser, this has now become and EXIF data reader for Quicktime(qtff) and mp4 video formats.
Currently able to extract and display data for the Track & Sample Atoms and most of their sub atoms but more work is being done to get better coverage of the whole file.
Used in Dongci - Video to .gif converter & Subtitle Studio - Subtitle editor for the forementioned purpose.
