[QuadList] Blanking Specs: Needed now? (was Re: DVE use to meet blanking specs)

[Ted Langdell]

General questions to the list:

There were obvious legal (FCC Rules), and operational reasons to  
insist on blanking to meet specs (tape exchange, smooth playback  
without hiccups on air or during editing among the reasons, pride in  
quality work is another.)

Times have changed, and with the demise of analog TV, blanking specs  
may not seem as important as they once were.

I think they are, but there's likely a need to "sell" the idea to some  
folks who don't see why you can't just "slap it on/in the machine and  
hit play," and to train people in how to meet the standards.

In that regard:

What are people finding for blanking as they transfer archives of tapes?

Is out of spec material causing problems during transfer?  Details?

What are you doing (if anything) to correct blanking for transfer to  
other tape or digital file formats?

Should blanking be corrected?

Some archivists would want the material transferred "exactly as it is"  
warts and all.

Thoughts?
