with "R. Proffitt"... The other thing we don't know is how the original tapes were recorded. Many of the tape-based camcorders had 2 record (and playback) speeds. "Normal", SP, was more forgiving across the manufacturers for playback.
Lots of people used LP which moved the tape at a slower speed allowing for longer record (and playback) time. This LP mode recorded on one manufacturer's camcorder rarely worked in another manufacturer's camcorder for playback - and sometimes was problematic when using different camcorders from the same manufacturer.
I have about 15 old 8 mm tapes that were recorded from 1998 till 2009 and so I bought a sharp hi 8 camcorder from ebay to watch and transfer, but none of them will play. They all have static. Put in a new tape and recorded and the play back was fine just a little static so its not the camera. My question is if most of my tapes were recorded on a Sony will they play back on a Sharp hi 8 machine?
