I found the recording of bthe 1218 a while back. The tape quality is deteriorating, and I have it and some of the children out to my son-in-law who is a videographer to digitize.
I didn't realize you could digitize your children now.
Technology seemingly knows no bounds.
On a serious note, you are absolutely correct about the deterioration of videotape.
The worst culprit is something called "Sticky Shed Syndrome" wherein the tape polymers absorb atmospheric moisture and the surface becomes sticky, causing it to stick to itself, the guides in the cassette housing and the guides, capstan and head drum of the video playback device.
I am in the process of digitizing my collection of VHS and Hi8 tapes. So far I've digitized about 120 purchased VHS railroad videos, 21 self-produced VHS cassettes and 10 of 23 self produced Hi8 cassettes. About 12 of the commercial VHS and one of the Hi8 tapes have been rendered unplayable due to the aforementioned Sticky Shed Syndrome.
I am attempting to rescue those by a technique I read about on video tech sites. I have sealed two of them in a vacuum canister (Foodsaver) along with packets of silica gel desiccant, the theory being that the desiccant will draw the moisture out of the tape allowing it to be played without the stickiness. I only need to get it to play through one time and then I don't need to worry about the videotape ever again.
Digital storage has become fairly inexpensive. Using a couple of multi-terrabyte external drives, I have captured and stored my original footage in DV-25 format, which is of extremely high quality and easily editable. One hour of DV-25 video requires about 12.7 GB of space. A one terrabyte drive will hold 80 hours or 20 full videocassettes.
The pre-recorded train videos were saved in mp4 file format which requires far less storage space, about 660 MB per hour.
Don't forget to backup the files onto another drive because drives eventually fail. You don't want to learn that the hard way.
One note for any one still using Windows XP. XP won't recognize any drive larger than 2 Terrabytes. One of my drives is a 4 Terrabyte which I can only use with by Macbook or Windows 7 computers. I use that one as my Master Video Backup, so that isn't an issue for me.
One final note: Maxell High Grade and 3M (Scotch) High Grade VHS cassettes played like brand new, even 30 years after they were recorded.
I had some issues with Fuji High Grade which I switched to in the final years of my VHS recording period (1988-1991)
They were all stored together under the same conditions so I have to conclude that Maxell and Scotch produced a better product than Fuji.
