Analog video and frame-by-frame review don’t usually go nicely together (unless of course you’ve got a CAV Laserdisc onhand). So how did security camera systems stretch the normal recording time of VHS from a couple of hours to upwards of a week? Why, with ingenuity of course! Watch this video and find out the juicy secrets!

Fun fact, most CCTV cameras still use analogue video rather than digital video for some reason. Even black and white cameras use composite video cables, which annoyingly means you get chroma artefacts on modern displays even though there’s no colour signal.

@charlescampuz5812 4 года назад

Just Another RU-vid Channel Pretty sure it’s to avoid the “Digital Cliff”, which the signal cuts off completely if the strength is too weak. Analog signal looks bad when weak, but it’s still viewable. That’s probably why it’s used for security cameras.

I wonder if a dedication to accuracy and professionalism is why there's no multiplexer "simulation"... on the one hand it would be an absolute pain to set up in a video editor unless there was a plugin available to do it automatically, but also you couldn't be sure of getting it right unless you had the original equipment to test it against. (I suppose there's also the issue that it could trigger off photosensitive epilepsy unless each frame was fairly well balanced against the others...)

@GDJason 5 лет назад

I spent a long time working in retail years ago and we had similar equipment. I think our's were set to run for 24 hours on one tape because changing the tape was on the opening list. We had one for each day of the week with and A and B set, so 2 weeks of video. Our stores usually had 16 cameras running through a multiplexer into the time lapse VCR. I always wondered how they worked, but lacked the motivation to find out at the time. I hated having to review footage, there was no motion detection so you just had to fast forward until you saw something. I was so happy when our stores started converting to digital recorders. Those things were beasts back in the early 2000s, we still used analog cameras so these things had massive capture cards in them with a coax wire for each camera plugged into the back. We had a rack of equipment for like 20 cameras. I remember the software being a bit slow and it was a bit difficult for some of the less tech-abled managers, but was so much better than tape. Great video. I'm glad you reminded me that I wanted to know how these worked!

@NJRoadfan 5 лет назад

There was also another application for VCRs that could "write" one frame at a time outside of surveillance. Back in the early days of CGI, people using Lightwave 3D and other 3D graphics packages needed them to copy their completed animations to tape! Why? Because the computers at the time were too slow to playback the rendered animations at a smooth 30fps (at least until the Amiga 4000 came out in 1992 in the case of Lightwave users). So a common setup was to use a single frame step VCR and a GPIO output on the computer to trigger the VCR to record the output...one......frame....at.....a.....time.

@martinum4 5 лет назад

That's a pretty neat idea

@CantankerousDave 5 лет назад

I was just about to make that same comment. Imagine the precision required to fire up the VCR, cue it up to a precise frame, pause it in record mode, load the completed video frame in the output buffer, take the VCR out of pause and "stamp" that one single frame onto the tape at precisely the right spot on the tape, and then put the deck back to sleep until the next frame is done rendering (which could take hours - trust me, I was there). Repeat ad nauseam, praying that it doesn't glitch out two days into the process. Imagine the wear and tear on that VCR's guts, to say nothing of your own. The company DPS had a card called the Personal Animation Recorder that let you play back videos from a dedicated hard drive, but I think they were individual images played "flipbook" style rather than a wrapped movie file. I always wanted one of those. Video tech was such a kludge back then as the Video Toaster helped lead the industry away from dedicated analog "Big Iron" switchers and effects boxes to multi-purpose digital cards, and things got even weirder as the industry transitioned over to digital video. I remember one hybrid editing system that had an analog video capture card as well as a mini-DV tape deck that fit into a 5.25" drive bay. Crazy times, man.

@markpenrice6253 5 лет назад

Those were different beasts from the surveillance machines as far as I was aware (as they needed to be tuned for very high quality, and often using professional Betacam instead), but I wonder if deep down they were actually using the same techniques and technology? And having seen a thing about the Video Toaster recently I had been wondering how the more complex material was prepared for recording, because until seeing you mention that I'd forgotten the technique existed. Thought maybe you had to make use of a lot of RAM and/or a large hard drive (certainly I've seen the former mentioned for some seminal Amiga animations, with one well known figure thanking friends for lending him a load of extra memory from their own machines!), and pre-render it all into a framebuffer which you then pageflip through at 30fps...

Here's a topic idea: There were VCRs that could write data to a special label that went on the end of the cassette. The VCR would write the current tape position every time a recording started, so you didn't have to search for recordings; the VCR could wind the tape to the right position itself. It would be neat to see how that worked.

@TopSpot123 5 лет назад

I still have a time-lapse VCR (maybe a couple) in storage at work. Before we switched to digital we used it with a quad with multiple image options and up until the mid 90's we had another box in addition to the quad that interfaced with our cash registers. It would produce a text overlay of the transaction data in real time over the quad output. When we upgraded the cash registers, we lost this functionality and haven't had it since. This video brought back a lot of memories, in fact I still have multiple security tapes from the late 90's. I'm just a nostalgic pack rat I guess.

Fun fact: "forehead" sounding like "four head" is actually a mispronounciation. It's supposed to be more like "foh-red" rhyming with the word "horrid". Hence the poem "there was a little girl, who had a little girl, right in the middle of her forehead.." which uses that rhyme. Because of jokes like "five head" and similar, the mistake is now the more commonly heard pronunciation despite being incorrect and through common usage its become accepted by the OED (as in English, usage trumps all) Isn't that interesting.

@kosie1991 4 года назад

かっ True, but it's in theory possible to extract very high detail stills from a much lower resolution video, by making use of the fact that stuff move subtly between frames. So the pixels encode slightly different information about the world between one frame and the next. Though thinking about it this would mean you could upscale video without making up fake information, but it's definitely harder as you would have to feed backward and forwards information in time to handle up scaling the start of a scene, rather than having a pop in effect, like you have with games loading higher quality textures. Man it's really cool all the opportunities that still exist.

@@TechnologyConnections You may have covered this in earlier videos, but how does a VCR know what playback speed to use? Are VHS players the first consumer analogue media playback device without a user playback speed selection? Actually, I believe older machines have physical switches...hmmm, was this for playback and recording? And finally, what playback speed did the VCR choose when playing back the time-lapse tape?

What happens to each feeds audio in a 4 way split screen??

@SeanBZA 5 лет назад

There is no audio in that application, just video, and often just mono video as well, as this needed less memory. Most switchers used a 2k RAM chip and a video flash ADC to sample the video, using 4 sample and holds to drive the ADC, and using the sync signal to determine where in the RAM to do the write. Output was a simple scan of the entire RAM to a DAC to generate video. The one I have somewhere used a Z80 and a 6116 SRAM for memory, with the control program being in a 2716 EPROM, plus the flash converter and a quad SH chip, along with some simple sync detection. Unused inputs would be set to a blank screen, and it could either do 2 or 4 on a single output, or switch in sequence, genlocking the output so the TV would not twitch during the switching.

@anchorbait6662 5 лет назад

@@SeanBZA that's way over my head but I'll definitely you word for it. I know some security recordings don't bother with sound at all. I was just wondering. Thanks for explaining that

@jazzman92478 3 года назад

Fun fact: These particular time lapse VCR's have a characteristic sound when they're in use. Each frame generates a characteristic "whup" when the tape moves and the head flies. In 24 hour mode, the "whups" should be around 3 per second, or 180 bpm. Very useful at a music conservatory where the VCR is, by default, a metronome.

@vladg5216 5 лет назад

@rasz 5 лет назад

yes, if you are a dolphin

@SeanBZA 5 лет назад

@@rasz Yes, because the low pass filtering needed for the sampling is so much better behaved, with a nice gentle roll off from 30kHz or so, instead of having to use convolution and have a filter that has very sharp phase shifts with frequency, meaning the reconstituted audio does sound different. 44.1kHz needs a good filter, and a single order filter will not do, it has to have multiple stages and a wild phase shift. 96kHz a simple RC works. 24 bit is better than 16 just for the dynamic range, and that you can get better correction from the master as well without having large audible quantisation noise in the recording after gain adjustment.

@gormster 5 лет назад

1. No the waveforms are identical. 96kHz is useful for *manipulating* samples, but if you don’t process them, then after a brick wall filter at 20kHz the two will be completely indistinguishable. 2. Yes, 24 bit has 144 dB or dynamic range (far in excess of human hearing) while 16 bit has 96dB (just a tiny bit smaller than human hearing but definitely in excess of any home HiFi’s capability to reproduce it). Again, 24 bit is mostly useful when recording, as your ability to boost levels later is greatly increased. Boost a 24 bit signal 30dB and the noise floor is still inaudible to human ears; do that to a 16 bit signal and you can suddenly hear the digital equivalent of tape hiss.

Watching your great jukebox videos with all the cams and the cam following mechanical micro switches that inevitably go bad reminded me of when I worked for IBM in the 70s and serviced their behemoth IBM Copier II (when they tried to compete with XEROX) which had a stack of about 30 cams to time the paper feed, timing, cutting, etc. The schematics with the relays showing the coil on one page and the contacts on another would confuse the best of us. I doubt that any of those machines still exist, but it would be fun to see your take on them.

SO much is being lost with the move to digital. I love it for so many reasons - but there is something so tangible and durable when it comes to analog equipment. Not to mention the ability to service/repair the equipment when it stops working...now with digital = just thow it away and get a "new"(refurbished) one, and within seconds your data is all there again because it was backed up to the cloud. (convenient but wasteful)
