A READER ASKS
I create television graphics for broadcast. I typically save my files for use in the JPEG format (.JPG). My question is how stable are digital formats like .JPG. Can we ever expect obsolescence of these seemingly ubiquitous files?
It is always suggested that one maintain a cautious posture when it comes to formats. There are really no guarantees. You can print a photograph from a negative that is over 100 years old but some computer files created a few short years ago cannot be processed on today’s computer systems.
BLASTS FROM THE PAST
Consider what happened to the Sony BetaMax® video format. The general thought was that there would always be a machine on which to playback the tapes produced in this format. How many home movies were made by early video users only to have them sit on a shelf with nothing available to play them? Conversions are possible but the companies that do them are few and far between and the cost is high. VHS® could be destined for the same end now that DVDs are all the rage. There is a possibility that DVDs will be replaced in the next 10 years. HD DVD® and Blu-Ray® are already beginning to edge them out.
Considering software applications: If you had Native files created in an early version of a illustration application that let’s say ran on DOS or the Windows® 3.1 operating system, the Native files from that version may not open in today’s operating systems. Some early JPEG files might be incompatible too.
Many applications and operating systems have become obsolete over the years. Unless you have the original software, opening files created in these obsolete packages today might be a challenge or even impossible. How about 8” and 5” floppy discs? If you have files on those formats you are out of luck also. Time marches on, formats and applications change.
The best rule of thumb to follow is to watch the formats, anticipate obsolescence and do conversions as required to keep your files up to date. Do not fall victim to changes. To ignore this simple fact one puts their files at risk. -33-
