The Magic of VHS and how SLP/EP May Have Ruined It - 4K Version

Ғылым және технология

I recently hit 5000 subscribers! To celebrate, I produced this video on VHS as well as 4k as you are seeing here. If you want to check out the completely VHS version, check out the link in the video description. Otherwise, stay put to watch in 4k…
But in all seriousness, when you stop to think about it, VHS really is magical. I remember when we got our very first VHS machine in the early 1980s… one just like this Hitachi… just having the ability to record something and watch it later was amazing. The era of timeshifting had begun. Skipping commercials, recording one thing and watching another… all that became a reality, and all thanks to an ingenious system and some magnetic tape. Did VHS have its limitations? Of course. Was it perfect? Absolutely not. Let’s take a look today at the magic that happens inside a VHS video tape recorder and see how one of the ingenious features that shaped our lives may have also been the culprit in our bad experiences with the format.

    What you said about so many people using SP or SLP and avoiding LP is so true. The last VCR I owned, toward the very tail end of the VHS era, _only had_ SP and SLP modes on account of this.

    I think part of the reason for this is because JVC-made and JVC-licensed machines didn't support LP for recording, only for playback.

    Both Beta and VHS must have experimented with adding speeds later... I remember our 8th grade class watching "A Tale of Two Cities" which someone had taped off TV and then selected a slower speed midway through recording the film. Since the school's Betamax machine did not support the slower speed, we watched "fast motion" fight scenes and with tracking distortion for the end of the movie, which turned it from a drama into a comedy and had the whole class laughing!

    In the UK, a PAL country. We never had SLP, we had SP and LP. The first LP recorders were pretty good because the video head drum contained four heads, two heads optimised for SP and two for LP. But as time progressed, and prices fell, the build quality and other technical aspects of the VCR began to suffer. In the end, unless it was a high-end machine, they started making recorders that just contained two heads in the drum that were optimised for LP speed but were also used for SP speed. The quality of SP recordings suffered and could not match the quality of the older machines because the S/N ratio was compromised by the much narrower video tracks. Also, because there was now a gap between each video track as laid down on the tape in SP speed, picture search was badly marred by thick, chunky noise bars, and poor still frame. Personally, I never used long play because I wasn't prepared to accept the reduction in quality, VHS wasn't that great to begin with anyway. Besides, in PAL countries, VHS from the start could record for up to three hours with the E180 cassette, soon to be followed by the four-hour cassette, E240 and eventually we had the E300 five-hour cassette, though the E300 was not recommended due to the very thin tape used. For most people, I'd say that was long enough.

    In the last VHS years, I used VHS compatible S-VHS; they were rather affordable. I couldn’t make a difference in sound quality, but the picture was massively better. Of course there wasn’t any material to rent. I used it primarily for family videos and taping of TV movies I watched later on.

    PAL country here. We only had SP and LP, although I think the LP speed was the same as SLP for NTSC. We got 6 hours out of an 180 tape, which I think had the same length in meters) as a 120 tape in the US? Anyway, LP was watchable, be it with some more color noise and the inability to pause the video with a normal image. I had a HiFi VCR and the sound quality on both speeds was perfect. I even used LP mode for audio only to make 8-hour mixtapes for parties. People often wondered if I had the radio on because I didn't switch cassettes or LPs even once 😆. But if the radio, howcome no commercials? It was fun getting those questions from people with that puzzled look on their faces. Nice to get a trip down memory lane again. I completely agree with marveling over past technology. I collect old stuff (just one or two per technology) just to show this to my kid and to visitors. VHS, CRT, LD, 16 mm and 8 mm projector, R2R, walkman, minidisc, 8-track, tube radio, 78, polyphon disc music box and even a cylinder player. It's amazing to think of the design of this old stuff with the limited tooling they had back then. People love watching this stuff work 😁 Thank you for this video!

    When I recorded video, I nearly always used SP because the image quality was poor enough at that speed; it got Much worse at the other two. And although I waited until I could buy a VHS HiFi machine, I still wanted the linear audio to be as good as possible.

    LP was not consistent between manufacturers. A tape recorded in LP might not play on every VCR. I had a HI-FI Panasonic VCR which I used to record audio from CDs before burning was a thing. Keeping track of the time stamp made finding each recording easy, and they sounded just as good. I also used it as a Hi-Fi audio recorder for my band. We'd start a rehersal, with the VCR connected to the console's audio out, hit record (in SLP mode) and jam for hours. Good times.

    We all knew the differences in recording speed way back then.. If you wanted to keep something for the long term you recorded it in SP or LP... You recorded in EP if you simply could not afford to buy more tapes. But also if you recorded in EP on a hi-fi machine on high grade tape you could get sorta decent results...still a lot worse than SP... On top of that when they went to "digital tracking" it did have a lot of difficulties with locking EP and LP recordings.. If you had manual it was fine. But for myself i adopted SVHS as soon as i could.. around 89'... and recording in EP was just a little lower than in LP.

    Back in that era, I stuck with Beta for the better video quality. VHS SLP was so poor that only SP was worth using, and then it was 2 hours vs. 3 or 4.5 on a Beta tape. I made the shift to VHS when HQ came along. I bought a JVC recorder with HQ that was finally decent enough for daily use. When SVHS came along, I went with that. Of course our TV sets back then had such poor resolution that we were used to a soft picture no matter what. I remember LD for movies - all that noise was gone.

    The interesting thing with PAL machines is the slower tape speed and difference in frame rate. With an E180 tape, those countries could still get close to the same recording time in LP mode that NTSC countries got in EP/SLP mode. You also had longer recording times in SP mode than NTSC countries.

    No simulation in the video. They were all recorded with hifi audio. At the EP/SLP speed, you can hear some lack of high frequency when compared to SP if you listen very closely. My plan was to switch to the linear audio heads for that portion, where the difference is very noticeable, however I found out in post production that I forgot to feed the audio into those inputs as well. I am planning a short followup video demonstrating that, however.

    VHS hifi is not tape speed dependant. The head drum is at 1500 rpm for PAL and 1800 rpm for NTSC. The only difference is the track width. So s/n is variable but frequency response is not.

    I think you must have used the HiFi track for the sound. At slower speeds you would be lucky to make about 4Khz on a good day. Voice was very muffled. The slower tape speeds made very little difference to the HiFi track; Voice was very acceptable, but music did lose detail. My comments are based on Pal.

    LP was mostly not used because many machines simply wouldn't let you record in LP. Over the years, of the 3 machines my family had, none recorded in LP mode. FFWD and RWD blanked the screen (white on one machine), so no preview at all. Considering EP wasn't that much worse than LP it made sense. The machines played LP alright, just wouldn't record in that mode.
