Hello everyone,
discussion today in our Special Operations Command History Support Center (Archives) centers around a lossless video format since .avi may not be around forever... and it may not fulfill the requirements of long-term digital video storage for more recently introduced video formats.
Claims here only to introduce a discussion for archival purposes without any real scientific proof ... we (our lead archivist and I) agree on .avi for video; .tif for imagery; and .wav for audio.
We are currently in the process of converting our 16 mm film artifacts (from the 1930s forward) into digital form.
We are trying to figure out what to do with them once we have them in digital form - the most efficient, reliable, and long-term techniques.
Please jump in and give us any ideas, suggestions, recommendations, techniques, solutions, or otherwise share your oceans of notions with us to help us get through our dilemma...
(grin)
Thanks for any assistance. . .
Until that time. . . Earl J.

Hello Janice,
thank you for the response.
quote:
The .avi is just a container extension. What codec are you currently using for your archives or are you using lossless/no compression? AVI lossless codecs I've used have been HuffyUV, Lagarith, and BlackMagic HD. What makes you think that AVI will go away?
We convert our captured images over to .avi through Sony Movie Studio Platinum 8.0 (yep, I'm a Sony Vegas fan - been one since Vegas 4.0)... not sure which CODEC Sony uses.
Our archivist and I agree on methods for storing our "essence" versions of digital files based on our decisions over what we need here in the office and what we can "predict" for the future.

Yes, indeed, you hit the nail on the head; we are looking for the best resolution we can get stored in a lossless and uncompressed format.
NARA and The Library of Congress have both yet to determine a standard for the rest of us in government service. We make our best guess at what we think we need and can use in the future.
We use .avi, .tif, and .wav as our baseline formats.
* * *
In our ignorance, we believed that .avi was a Microsoft proprietary format...
much like some people believe that .pdf is an Adobe proprietary format...
In any case, our primary factors are lossless and uncompressed for the essence (original images/video/audio) of our files.
We eventually make faster loading, more easily transported, and easier to store versions for researchers (.mp4, .mov, et al.).
So, although some think that Microsoft "might eventually" abandon support for .avi, it probably isn't going anywhere for a really long time. (grin)
Our real question is:
are there any other lossless and uncompressed formats that could be used for archival purposes...?
Any help and guidance is certainly welcomed.
Thank you very much...
Until that time. . . Earl J.
