Best video format for the future (archiving)
by lsl - 2/13/07 11:33 AM
Over the years I have painstakingly digitizing my whole collection of home movies that had previously been stored on VHS and VHS-C tapes. I did this by capturing the video using ADS Technologies Pyro A/V Link and Pinnacle Studio Plus. Im currently using version 10 of Studio.
By default, Studio would capture in a DV format. The file would have an .avi extension. At the time I was under storage space constraints and so experimented a little with various formats so that I could permanently keep a copy of the file on the hard drive while keeping within reasonable storage constraints and at the same time having a format that would maintain a reasonable resolution when I would extract sceans for my home movie projects. Also, at the time, I was not really doing much of any video editing. I was just focused on converting my tapes over to digital.
So I settled on the MPEG-2 format. I would capture in DV and turn around make a file in the MPEG-2 format with no editing. (I used the DVD Quality default setting in Studio 720x480, 29.97 frames, sec.). Even today, I perform the same task when I transfer video from my Panasonic mini DV camcorder (although I dont use the ADS box) I think Im right in saying I did loose some quality when I converted to MPEG-2, but I could barely tell the difference.
Now Im doing a little more (actually a lot more) with video editing and DVD creations and again have been experimenting with various formats. Not so much for storage space as for questioning myself if Im using a format that is stable and has some legs to it in this ever changing environment. Basically, a format that I can confidently use 10 years from now.
Here my current dilemma and situation: Without getting into my hardware setup. I currently maintain a copy of the file on a hard drive. I backup a copy to a second hard drive and I burn a copy to a DVD data disk for offsite storage. An additional part of my problem here is that some of my MPEG-2 files will not fit on a 4.7GB DVD. Splitting the file is not an option.
A new twist is that Im keeping an image file of the DVD also on the hard drive as well as a backup and a second DVD. Ive found that I can play the vob file in WM.
So my question is What is the best video format for achieving?
Thanks in advance
