This is a fun video: SONY Edit Station ES-3 demo. Here are some specs.

Dual Intel Pentium III 500 MHz or faster
Windows NT 4.0 with Service Pack 6a
Main Memory: 256 MB or more
Matrox Millennium G400 Dual Monitor 16MB AGP
SCSI Controller: Adaptec AHA-3950U2
HDD: Min 2 x 7200Rpm Ultra 2 SCSI Hard Disk Drives for DV/DVCAM Compression
HDD: Min 4 x 18GB 10,000Rpm Ultra 2 SCSI Hard Drives for Uncompressed Video with Optional ESBK3032 Software

In 2003 Sony established Sony Creative Software, I suppose to provide better tailored software. In 2016 Sony sold off Vegas, because I guess Sony did not need it anymore, and Firewire has long been forgotten.

This is why I fall back to the analog side using the MON (super) output of the deck itself rather than rely on the trickery of the monitor. All of my Sony BVM monitors are stupid with no digital anything in them, the Panasonic TAU widescreen does have the smarts on the HDMI side and most of these can be accessed & modified in the hidden service menu while the analog side only gets the R+G+B and geometry settings that are specific to the aspect ratio in play. The Samsung on the other hand has all the wizardry and tricks to make everything look picture-perfect. I turn off all the mpeg and other filter enhancements to go as "raw" as I can but it's still a scan converter, honestly I'd much rather have the Panasonic as my primary monitor however the logistics of my home make that very difficult so I put up with the Samsung. It's mounted to the wall over the gas fireplace and I have a Dell 9020 i5 micro Linux box feeding HDMI-3 with a really cool autumn background image, we call the Samsung "The Picture Window" and at 1920x1080 it looks the part.
One thing the Samsung does well is straight analog composite with all the fancy enhancements turned off. I can feed it say my Laserdisc (Philips CDV488) or Type-C (Sony BVH-2000) and it really looks about that of a DVD. Both of these sources have a high S/N ratio to begin with and feeding it an amorphic widescreen 480i it does quite well with the details.

I came across interesting info from a reasonably reputable source, that for base DV, DVCAM, DVCPRO25 and even for Digital-S, frame size is 720x480 for 525/60 and 720x576 for 625/50. But DVCPRO50, allegedly, has 720x487.5 for 525/60 and 720x583.5 for 625/50. Not a big deal, but I think these are the same numbers as on Digital Betacam? Did Panasonic mean as seamless interop with DigiBeta as possible, or this is a mistake in the docs?

Post production resolutions in storage vs display given the pixel aspect ratio. Digital Betacam is 720x486 in a 10-bit YUV @ 4:2:2 running a 2.34:1 DCT compression to yield a 90Mbit/sec data rate plus 4 channels of 20-bit 48Khz/sample uncompressed audio and a 5th linear audio cue track according to the front page of my DVW-A500 service manual. Active lines vs total lines which include the vertical blanking bar are often interchanged.

I made a video about the history of DV. Missed some things, but I think it is watchable :) I will make an addendum with more tech details and rumors.

Here is a link to the video on Youtube: History of DV - the first consumer-grade digital video format.

It was well done and to the point.

Thank you for the offer, I have not yet looked at any of it.

And, I take "fringe" and "weirdo" as badges of honor in my collecting habits. :D I am happy if I am not the only one.
