Now, during the holidays, it is a bit of time to copy the time stored on magnetic tape image and sound to new media.
The video recordings of the early 90s were still analogue on 8mm tapes instead. No, not Super8 (that was the movieformat like in cinema those times but much smaller), but on Video8 or HI8 (the better quality variant – comparable to VHS and SVHS, where the „HI“ or the „S-“ technically by a separate recording of the Y – and C- signal was realized (Y = luminance, so brightness information and C = chrominance, ie color information) .The recording itself, took place on magnetic tape in helical-scan technology (as well as VHS, U-Matic, Betamax, BetaCam, Video2000…). Except that the tape just has a width of 8mm and not 1/2 „or 1 inch, as with other systems. Also the sound is recorded in the helical scan.
In order to get the old records into a digital format that is common today, you need the following four things.
First, the tape (cassette) with the probably exciting content of days gone by. Next, a player is needed.
Here I got myself a then professional HI8 recorder, with which the playback of the tapes should work. The recorder is called EV-S9000E from Sony and came back to the net after almost twenty years break. After a short while, the smell of putrid fish was noticeable. An indication that some electrolytic capacitors of the SMD design are no longer in order. (A well-known problem with devices of older age and elko’s smaller, more compact design.) Nevertheless, I left the recorder on the net and made myself smart, which functions failed because of the numerous, not value-accurate components. So the power supply started and delivers at least. The flourescence indicator has failed. The 60V anode voltage seems to be missing here, no matter the tape drive works, so bring the analog signal to the computer.
For this I got myself a video to USB converter of elgato. Quickly installed the necessary software and inserted the first tape and pressed „Play“. The picture, however, was a disaster. All lines were totally distorted and offset. (As if the line frequency was wrong). So, before I put everything together again and disappear with the recorder in the workshop, I have again seen in the Config menu of the recorder. There I switched all AUTO options to manual, the television standard on PAL geknüppig and last but not least the TBC (TimeBaseCorrector) off. Lo and behold, the TBC is over too. Actually he should generate an absolutely stable time signal for the video line, but with defective electrics this is no longer possible.
Since I do not have ten tapes to digitize, the recorder should hold out …
