Great stuff. I collect my first C format machine, a VPR2 in a few weeks. It's not been used in some years, so will certainly need some work. It's all going to be new and scary for me, it's not a format I'm familiar with.
Thank you very much for this video! I've seen lots of B-format reels in the Bulgarian National TV back at the beginning of the 90's, always wanted to work with this huge fascinating video tape machines. :-) Now I have pro-programs at home and am only smiling with nostalgia. Still it is magnificent piece of technology. :-) And you are a great teacher.
If you find one - look for the VPR-80, or Sony 2000 series... or if you're really lucky an AMPEX VPR-3 with it's matching TBC. The VPR-1 'could' be an A-format converted to C-format (VPR-1C), not nice.
I used to be able to lace and line up for playout in about 30 secs. Vid level controls were generally done on the boards, not the front panel, and unless there were sub blacks, you should never adjust black level on programme material, likewise unless pek white is over 100% on prog material leave it alone. Line up is there for a purpose, if you start tweaking on prog , material then how on earth do you expect to match it if a retransfer for repair needs to be done. Plus, watching demod out is no good. The TBC will fill in small drop outs. Demod is only useful for line up adjustments, and for diagnosing problems if visible post TBC. Also why did the line up not start with a scratch test, then tracking??? Looks like a bit too much reliance on AST heads.Oh, and please zero the counter at the beginning when the tape is first loaded, and put a pip in to cue back to.
After 25 years of watching analog over the air TV stations that were weaker than the boiler on my first shower (which is a weak as American lager beer) and watching VHS tapes these video glitches are hard to notice. Yes there's room for improvement but most of my life I was doing the equivalent of watching TV with the wrong prescription eyeglasses wrapped with Saran wrap.
Thanks for sharing. Happy Memories! That's Ray Moore, OOV at 10.00 (1 inch Dropout). 'One inch' was a 'walk in the park' compared to 2 inch Quad. Both formats are now consigned to history.
Quad was awesome. It had a much cleaner tape path. All those guide rollers and heads in constant contact with the tape on helical machines were terrible. No wonder the heads wore out fast. I worked on every model of quad that Ampex ever made.
@@rty1955 if you want to do multi generation dubbing/editing from 1" tabe didn't the video noise increase much faster than dubbing from 2" Quad, resulting in you having to return to an earlier edit and starting again?
@@Robert_Manners the newer TBCs on 1" where much better than the video processors on a quad. But you were still very much conscious of match cuts that was a generation apart. You edit decisions and generations were critical to good edits. Back then we were concerned with burst flips , which were color burst signals that were 180° out of phase, horizontal timing that was slightly out of time with a previous scene and other various details of a complex video signal.
I remember doing dubbing commercials in on spot reels, I used to do about 15- 20 an hour (in between running the on VTRs recording incoming programs, etc)
Re: The Capstan Servo Errors (where the tape speed drastically decreases at regular intervals) - I don't believe this is a particular fault of the tapes per se. I think this is due to a lack of oversight regarding what happens to these tapes over time, and should be relatively easy to prevent. Firstly, the edge of the tape containing the control track is clearly not being read properly, and there are two possible causes, which may be occuring singly or doubly. Firstly, the alignment/azimuth of the control track head may be out of spec. It can seem in spec with a line-up tone but that's when the tape tension is at one extreme in terms of the edge torque, because the take-up spool is pulling the tape at its hardest, meaning the angle at which the capstan is pulling each edge has a greater differential than it will as the take-up spool fills up. Secondly, the edge of the tape may be getting slightly stuck to the inside of the feed spool flange, meaning that the edge of the tape curls away from the horizontal plane. In both cases, this means the control track head doesn't read a coherent signal, but reads the wanted signal along with a pre- or post- image of the control signal slightly out-of-phase, meaning where it should be on the positive peak, a bleed-through component from the negative part of the phase is modulating onto it. For parts of the tape whose edge curves away slightly more than the rest, this can overcome the tach servo and TBC, causing the servo to slow down in the belief that's going to correct the phase, and it keeps going because it never corrects. Also there may well be a slight stickiness on the capstan itself. Two things that could be done, is to fit a guide (preferably with brushes) just before the head stack to flatten and clean the tape edge before it goes over, and another is to take the top flange off the feed spool, so that it feeds into the machine as an open pancake. This allows the tape edges to partially, naturally uncrinkle as it unwinds, and also to prevent any crinkling that might happen DURING playback.
..and OOOH! how easy it become after U-matic.... this is beautifull video what really could go wrong, at the first place of recording a 1 program in 70`s and early 80´s, people dont get it at all... iMOVIE generation dont know where they coming from...
Maybe you could edit this video around 10:00 mins, and cause a COMPLETE audio AND video dropout, when Jimmy Saville is about to appear... ✌️"Whoops, lost him!"✌️
I still prefer to watch the old analog picture tube TV. Most TV station signals are still intended for old vacuum tube TV receivers which are still in 4:3 format and a few are in 16:9. When played in a digital wide screen format, the pictures are distorted, stretched sidewise, and pictures of people look short and fat. Moreover, I am bothered by the "mapping" in the faces of persons due to "connecting dot effect" of digital colors. Unlike the old analog signal where the change of shade is smooth, digital pictures shadows are abrupt and in steps. There are channels which show pictures with large black strips on top and bottom, rendering the big screen useless.
What kind of terrible TV stations do you watch? O_o TV stations have moved well Beyond analog TV production, and in most cases have full digital workflow o_O
Most people are "aspect blind". They can not differentiate a normal picture from a stretched picture. Most TV broadcast are stretched like football and basketball players that look short and fat, and newscasters with over-broad shoulders and fat cheeks.and long ears. People who are not bothered by this distortion are known as "aspect blind". It seems that you are one of those not bothered so it's OK.
I suspect that this has more to do with how the images are displayed, rather than how they are broadcast. People generally dislike having portions of their TV picture with black bars on, so they'll alter the controls until the screen is filled with picture - whatever shape it is.
Odouls77 I'm pretty much the opposite, I can't stand poor AR, and get regularly annoyed at the few retrograde broadcasters who fail to set AR flags properly forcing me to adjust display AR manually, but there are next-to-no channels that actually broadcast stretched material. Stations have been broadcasting widescreen content for a very long time, and are pretty darn good at it, same goes with wider ARs. In most cases, if you're seeing it wrong, it's because you've not set your TV properly.
Phil S That's possible, though black bars wern't any different on CRT TVs. If people refuse to set their system up properlly they can hardly complain. TV tech has never been better than it is today.
the black setup level would never pass FCC regulations in USA. we use NTSC standards which call for black to be at 7.5 IRE. This allows for any black not to dip into the sync part of the signal which could make some TV receivers to lose sync
That is for NTSC only. It's PAL in the above video, on which a greater degree of separation between black level and blanking level is achieved in the design of the PAL system as the sync level is at -43IRE, as opposed to -40IRE. Peak level is +133IRE as opposed to +120IRE. Burst is 21.5IRE instead of 20IRE.
And in comparison to NTSC and PAL, NTSC-J (the Japanese variant of NTSC) does allow for 0 IRE for black in the video though, compared to the 7.5 for NTSC used in North America/Mexico/South Korea. Most newer receivers/monitors (especially those for the Japanese market) can handle 0 IRE in the video lines and not mistake it for sync (I'd guess by the sync processing circuitry of the monitor/TV paying attention more to sync timings rather then levels). That being said, NTSC-J is compatible with its North American counterpart mostly, usually all that's needed is an adjustment of the brightness control.
