Media Metadata - Tools I use: EXIF Reader and MediaInfo

JPEG and EXIF

One of the major advantages of digital media is the attachement of digital metadata within the image. In the case of imagery, JPEG and its metadata header, EXIF, are typically the normal solution for organization as processing. For imagery I thing EXIF Reader is the one I prefer and I have used a number of them over the years.

Video on the other hand is a jumble of formats and the sorting out of all the confusions of COTS handicam and prosumer systems with competing HD formats of essentially competitive slants on “standards” is litterally a pain in my Xss via my wallet's digestion of its hard-knocks. For me, MediaInfo, has allowed a number of lights to finally go on for me as I have wandered the waste land of MOV, MPG, AVI, H.264, and etc.



Introduction


Exif Reader is image file analysis software for Windows. It analyzes and displays the shutter speed, flash condition, focal length, and other image information included in the Exif image format which is supported by almost all the latest digital cameras. Exif image files with an extension of JPG can be treated in the same manner as conventional JPEG files. This software analyzes JPEG files created by digital cameras.
Exif Reader can analyze some maker-specific formats such as Makernote. This software can display the image information in more details than any other Exif analysis software. For details, refer to the operating environment.

In addition to the Exif format, Exif Reader is applicable to the TIFF/EP format supported by CANON EOS D Series and Kodak digital cameras for professionals, the NSK-TIFF format by the Japan Newspaper Publishers and Editors Association, the TIFF-FX format for FAX by Xerox, and many other special image formats.
