Technical file quality is an important consideration for digital video. Videos that are posted on the Web, for example, are often grainy and have less information than the original version.
Save the highest quality versions of your videos along with good descriptive information about them.
You may have many digital audio files with music, lectures and other sound recordings. Some of these have personal, financial or other value that leads you to keep them for a long time.
You should make sure that the audio files you select for saving are in an open file format. This will ensure the greatest flexibility for future use.
