IASA-TC 06 to be published in phases
First edition• Focus on carrier-based recordings, i.e., videotapes(mostly analogue)
First version• Online only as set of PDF files, second version will
also be in print

What about file-based born-digital video? The second edition of IASA-TC 06, coming in the future, will treat
born digital video. For the moment, here is one useful source of information about file-based digital video:• http://www.digitisationguidelines.gov/guidelines/video_bornDigital.html
There are others as well.
