There was a Digibeta for Star Wars 1997 Special Edition released years ago but not officially.
It was horribly compressed with digital artifacts and DNR. There also were dropouts that had to be patched with what i assume is the TB version.
Now that there is a 35mm scan a Digibeta source is a waste of time. At the time some considered the Digibeta better than the Laserdisc.
There also was allegedly a digibeta of Empire 1997 but i don’t think it was released.
