The visual quality of U-Matic was far better than the 1/2" formats be it Betamax or VHS for a number of factors, that image taken from 1977 appears to be a first generation as it doesn't have the L/C ringing and very little chroma smear. Larger head drum with a higher tip velocity and better mechanical stability gives U-Matic a far better timebase stability. 3/4 U-Matic editors after 1980 had a number of improvements in the processing of the chroma/luma separation that in the real world were able to meet the 250 horizontal line resolution without a cross color contamination.
I am in the process of capturing & digitizing some of my 3/4" archives using my VO-2850A as a source feeding a DVW-A500/1 with the BKDW-505 composite card, the A500 has the ability to digitize the analog input and convert to SDI in realtime without compression. Once everything is edited I will upload a sample to YouTube so you can see for yourself how good U-Matic can be.
