Dear Contributors,
Babycat's Question: "Is there any classic porn in high definition?"
It's an interesting question (particularly if you're a geeky video editor like myself. I spend too much time optimizing digital video and messing with compression formats, I can tell you...)
Technically, the answer is "no", when you consider only a few japanese companies began producing true HDTV systems in the 1970s. (Sony and the like). These didnt trickle down to the rest of us until the 1980s. However...
... If the porn studio was using 35mm film to make their productions (before 1970) then each frame of that film would have a resolution of 19.4 megapixels.(This is because a 35mm frame of film is equal to 5400 x 3600 pixels). Just so you can understand how "high-def" that is, a standard 720p "HD camera" only displays images with 921,000 pixels, thats less than 1 megapixel!
I suspect most of the bigger porn studios released DVD quality films (usually 720p or even 460p) in the 1980s. In other words, you'll be lucky to find a "classic movie" even in 720p (less than 1 megapixel) from any studio during that era. Before 1980, when analog cameras were still standard equipment, it would depend entirely on the quality of the camera and film stock the producer decided to use.
These days TV manufacturers are moving towards 4K (8.3 megapixels) and even 8K (33.2 megapixels) display systems, known as "Ultra HD". The problem for us mere consumers is that you need both a TV that supports Ultra HD and content that has been produced using high-def cameras to really "feel" the benefits.
Since you mention Christy Canyon, you could probably optimize her film output if it exists in true 720p format. I wont go into the technical details here, unless you get back to me
(It takes abit of time to master the software tools needed).
