At least of the original brands.

I can't say for France but outside of there, there were hardly any purely SECAM recorders. I don't remember a single one that would be SECAM but not PAL at the same time. Even those that were SECAM enabled were usually ME-SECAM, which was basically a PAL machine with a kind of slightly modified PAL circuitry that did not reject the signal as not conforming to PAL standard. The disadvantage was that such recordings (non-scientifically-confirmed but possible, subjective impression) were more colour distortion prone. While SECAM broadcast signal was generally good, home recordings using ME-SECAM equipment showed degradation substantially faster than PAL recordings. -- SD! - http://e4aws.silverdr.com/ Message was sent through the cbm-hackers mailing listReceived on 2017-09-01 22:00:02
