Documentaries And Doing It For Real
Added 2024-04-29 12:40:18 +0000 UTCThe current craze of making everything more better by creating artificial detail and painting over actual footage just creeps me out to no end. Let me rant about it a bit.

What I have been waiting for is a "tool" that corrects frame rate conflicts that occur even on today's video cameras. You know, that line slowly creeping up your Commodore 64 monitor is obviously a timing/frame rate mismatch. Even dash-cams today show "flickering" of LED street lights and car tail lights which are totally undetectable directly to the human eye. A 30 frame per second old analog NTSC camera shooting directly at a projection of a 24 fpm film resulted in terrible distortion and vice-versa. You had to have a "film chain" which is what they called it in TV back then, to make a 16mm film at 24 fps look perfect on a 30 fps system. Commercials in the 70s were all shot on 16mm film and had to be manually spliced together to form one commercial break of commercials in a TV show. Your method of capturing film cleanly on HD requires that intermediary conversion box as well. I think they'll need a very clever AI to recognize multiple sources of "flicker" in one frame and correct that problem only without creating artifacts liker you're describing. So, for all the film that had to shoot mismatched computer or TV monitors that "flicker" is still there. You can even see on old TV shows shot on film, like Kojak or Rockford Files, where they have a TV in the scene, you can clearly make out that the the CRT is actually being "masked" by another film source to avoid having to deal with shooting real TVs that flickered like hell. Probably a green screen type of effort, or an even easier insertion method since the TVs usually didn't move at all when the fake images were being inserted. The worst nightmare was recording CRT displays in military and commercial aircraft, like the F-18 A/B and 757/767 which both had multiple un-synced CRT displays. If you were able to adjust the video camera to account, as best as you could, to one CRT, the others would still be out of sync. A real mess. But our eyes can't see these CRTs "flicker" when being directly viewed in person. I remember the monochrome CRT displays in the F-18 and 757/767 had an even more insidious timing problem. That problem was that the rather large "graphics generator" black box was drawing one frame of vector graphics for text and symbols and then the subsequent frame for raster video, like a FLIR target in the military mixed with text or a weather display mixed with symbology on the commercial displays. As always, the human eye could not detect these very different format changes as the aircraft displays did not have to conform to the old NTSC TV analog color video frame rate or analog composite color images which are "mushy" even on an incredibly expensive CRT display system. So, in those early years of airborne CRT displays, both the military and civilian displays played this vector/raster scan combination that worked perfectly in person, but looked like hell when a video, or film camera, tried to shoot straight off the CRTs. This is still a problem with cockpit displays today, but not anywhere as near as terrible as CRTs. The LCDs have a "frame rate" of some kind and video cameras can "see" that conflict and all kinds of artifacts cam be seen if more than on one LCD source is captured. Usually things like the primary large cockpit displays are not hard to "adjust" away the timing problems. But the secondary LCD backup displays, like the 3" horizon/IAS/ALT displays. Would present a problem. But it's far less a problem now that CRTs are essentially gone and LCDs are far easier to capture. It's interesting to note that the thousands of 757/767 CRT displays built in the 80s are no longer serviceable since the CRT manufacturer, Toshiba, simply could not justify keeping the specialized color CRT production lines running just for aircraft use. They gave the company a "last time buy" of CRTs in the early 90s and then Collins redesigned the former CRT displays to use form/fit/function LCD equivalent replacements. The C-17A and F-18 CRT displays are also replaced with LCD replacements. The LCD replacements usually have a "false rear" since they have to slide right into the position of the former CRT displays and their connectors. Without a heavy and deep CRT, and dated analog electronics, the new LCD units don't need all that space and are lighter and run a lot cooler than the CRTs and associated high voltage power supplies. That's the challenge of electronics used in the aerospace and defense industry. The equipment is so hard to build, test and certify that it sometimes has to work continuously for decades as aircraft are expected to last that long. The real driver for electronics is consumer products, so niche industries that need smaller quantities of outdated tech have very real problems supporting it. This has WHAT to do with AI? I got lost...

2024-04-29 19:52:01 +0000 UTCI saw this on the livestream. I'm glad you added the original footage to the edit, it looks just as it should!

He even amended the lighting this week to have a warmer feel, and it looks superb. He regularly gets people wondering why he isn't streaming in "glorious" 1440 - they just don't get it.
