A Trip Down Market Street Before the Fire Prelinger 4K to 2K scan from best existing film material



This scan of the legendary pre-earthquake film was made from the best existing material at 4K (4096 x 3072) resolution and transcoded to 2K (2048 x 1536) for YouTube. It was scanned by Adrianne Finelli at Internet Archive on October 11, 2018 using a Lasergraphics ScanStation scanner at 5120 x 3840 and scanned to 16 frames per second. Due to the limitations of Final Cut Pro, every second frame is doubled for a playback rate of 24 frames per second, so the running time remains the same. The part of the image that lies between the film preparations is exhibited here for the first time.

Anyone may reproduce or reuse this scan. Please attribute it to its source: Prelinger Archives.

Tom Cruise Hates Motion Smoothing

Sniper007 says...

There's a whole specialty field called "display calibration" that goes deep, deep down this rabbit hole. And yes, they (Tom Cruise and the guy whose name you can't hear because Tom interrupts him) are correct. Motion smoothing is violating image fidelity. It should be turned off.

We are stuck with 24 frames per second in movies, forever. Peter Jackson tried 48 frames per second with The Hobbit. It failed because it felt like the "soap opera effect".

But in almost all other video contexts, more FPS is better. Obviously in gaming more is better. YouTube supports up to 60 FPS, as does most decent recording software these days.

The blue shift that almost every TV has when on display is also a result of funky default settings. The human eye perceives a blue light as slightly brighter than a full spectrum light with the same intensity. So it works to sell TVs. And when you switch it off the default color scheme, you're first impression will be that the picture looks muted or even yellowish. This is because you are accustomed to seeing way to much blue.

If you are a true video aficionado, you'll get yourself a color meter for a few hundred bucks and do an amateur display calibration on your set.

If you are a video psycho (of if you sell faithful video experiences to an audience like in a theater) you'll hire a professional to come out with a high end spectrophotometer and calibrate each display input properly using a standardized video source.

I'm going to be disappointed if the 1000 degree Red Hot Rocket Knife Gun doesn't show up in a FPS sometime in the near future.

A PC Gamer's Worst Nightmare

SeesThruYou says...

Heh... I remember gaming when frames per second wasn't even a thing yet. Ultima Underworld on a 386 anyone? Or better yet, how about Midwinter on an Atari ST? Kids are spoiled these days.

Boom Goes The Dynamite - Bridge Demolition @300 FPS

Quboid says...

What does that actually mean, 300 FPS? Recorded at 300 frames per second, on it's own, doesn't tell me anything.

Is it playing back at 25 FPS, therefore it's slowed down by a factor of 12? Or (just to illustrate my point) is it played back at 900 FPS, therefore sped up 3x?

NASA | Fiery Looping Rain on the Sun

YoDaDeeOh says...

from the YT description:

The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.

Can someone help me with a doubt I have about this video? Is the motion of the flare and the sun surface in real time? Does it really move THAT fast?
