I am no expert, but I have used 346 in the few RDA records I have made
for DVDs, specifically so that I could include PAL/NTSC information. I
have seen other records in OCLC that do the same thing.
Perhaps the word "analog" in the description is unnecessary.

The Library of Congress MARC21 Bibliographic Formats
(http://www.loc.gov/marc/bibliographic/bd346.html)
and the OCLC Technical Bulletin 261
(https://www.oclc.org/support/services/worldcat/documentation/tb/261.en.html)
both describe field 346 as: "Technical specifications relating to the
encoding of analog video images in a resource."
RDA 3.18.2.1 says:
Scope: Video format
<http://access.rdatoolkit.org/document.php?id=rdagloss&target=rdagloss-2102#rdagloss-2102>
is a standard, etc., used to encode the analog video content of a
resource.
For instructions on recording the format of digitally encoded video,
see 3.19.3
<http://access.rdatoolkit.org/document.php?id=rdachp3&target=rda3-5264#rda3-5264>
So should there a field 346 for a DVD as it is a digital, not analog
resource?
If we do not use field 346 for DVDs how do we indicate the video
standard (NTSC, PAL, SECAM)? These standards have survived into the
post-VHS era, and can still affect playback (DVD player and/or TV
incompatible), but are not specifically catered for in field 347.
One possibility is to use 347 $f Transmission speed, entering 30 fps
for NTSC and 25 fps for PAL, or just entering the abbreviations NTSC
or PAL.
With regards to these new fields I presume we are still waiting for
the dust to settle, but I do not want to go back and change old
records more than once.
