 Howdy welcome back. Today is March 27th where I am at 11.15 a.m. It is a Wednesday here on the East Coast. Thank you everybody for joining me today on The Bunker. I have a couple things going on. I'm gonna be showing you a little bit more about time-based correction today. I've got a setup here that I wanted to document. And the easiest way to do that was to go live with you today and show you exactly what I'm talking about. So thank you for showing up today. I'm not expecting a huge crowd to turn out for time-based correction stream. So if you are here, please do me a favor and hit the like button and that will help our reach. I wanna thank the early people here in the chat. Rob, Kat, Trollpats and Darth Ligma. Thank you all for showing up today. Hey, Ronnie. Welcome in too. And so that's what we're gonna be working on. I've been trying to do some things on the stream setup but still not having a whole lot of improvement luck here and it's not a big deal again because pretty soon the bunker's gonna be moving. So that should be coming towards the end of April. And while it's been a fun two and a half years here in this bunker, we have good things coming and a larger ability to do more restorations and space to work around and more, a better looking studio probably. So I'm excited to see it. I'm excited to show it off. I don't really know what's going on. That's all still working itself out. But in the meantime, we're gonna be down here in the regular bunker and I have had so many projects coming in. If I'm looking at my big board here, which is my Qboard, it's ridiculous. In the shop right now I have three PVMs, one BVM, a PCCRT, a time-based corrector and then four Toshiba CRTs that are all televisions. So I've got myself loaded up with just a ton of work here and as I do have footage shot from two CRTs that I finished, I've just been packed with work. So hopefully as, I mean, I'm probably gonna be jam packed with things up to the move, so I don't know. I'm gonna try to get one of those videos done at least before I move on either the Sony or the JVC. I've tried to probably do the Sony first since that was the first one done. The Sony KV-1, FS-120. Oh, excuse me. All right, so thank you all again. Alex, Zefkor, welcome in everybody. Thank you all. As you can see on the side of your screen here, we do have the setup for the time-based correction test. Try not to jerk the camera around, get my arm off the desk here. I'm gonna fire it up. First off, we're gonna be using a Sony BVM. That is the 8044QD. It's a high resolution BVM. And I'm gonna use the other microphone so that I can talk to you more when I get over there. But that's what we're gonna be using. I've got a JVC VCR player. This is my best VCR player that I have that's working right now. I have a couple others, but they're dead. Then I have another one that works, but it's not nearly as good as this one. This is a JVC. It has S-Video. And what else does it got? It's got like dual output. So the good thing is for this test, I'm gonna show you both S-Video and composite video. They come out of this machine simultaneously. It's a high resolution VCR, so it puts back one of the best images out of any VCR I've ever used compared to other ones. But we're gonna test the time-based corrector. That's right. And first off, let's just talk about why, why would you even need time-based correction? This is a problem that was primarily for, I'm gonna turn down this music a little bit. I'm gonna turn actually, let's go ahead and for now I'm just gonna pause the music and turn it off. I won't worry about that. So time-based correction. What is it? Now, it's kind of complicated, but what happens is there's a signal, of course, the analog video signal is what we're working with. And time-based correction is based upon mostly tapes. Sometimes DVDs have it. Have a little bit of this in it. But most of the time, what you're needing a time-based corrector for is to, and this day and age, it used to be to kind of copy tapes or back tapes up, VHS tapes, Betamax tapes. What would happen is on the original copy of the tape, you could have a couple of issues, right? It could be a tape that's loaded with security like macro vision, which I'll show you here in a second examples of that. And also there could be timing issues in the tape where the tape gets out of sync a little bit. And then when that happens, like your audio and video get out of sync on the tape or something on the playback, like if you have a, you miss a frame, like that happens, frames get dropped on a tape player. It's a very crude, elementary form of playing back media. So it had a lot of inconsistencies, obviously in the playback. And what would happen is that signal or your signal of playback, when you try to capture that, your capturing device, whether it's a capture card or a VCR, it may have a lot of issues capturing the video that you're trying to take from it because either the timing gets messed up, again, colors could be thrown off. A lot of things can happen in this process. So, back in the day, there were tons of devices that were made to try to help correct this signal. And they're commonly referred to as time-based correctors. The one we're looking at today is the data video, TBC1000. And it's based around this. This is like the brain of this particular device, and it does. It just looks like an old kind of capture card, maybe from the mid to late 90s, but there is no interface here to like read with a PC, but it is designed to, you got power coming in to the board, and then you have a video signal that comes in that can be either composite or S-video with audio. The audio is just passed through the output over here, and then actually what it does is it spits out the composite video either here, or it spits out composite and S-video, or composite video on this, and then that goes to a video board that actually is inside that box. It goes to another video board that amplifies the signal and sends it out to a lot. I think it's got C, A, B, C, D, I don't know. It might have four outputs of composite and four outputs of S-video total, and they all do it simultaneously. But this inserts a frame. If it drops a frame, it's ready to insert a frame, like a color bar frame. It's ready so that the device that you're using doesn't just see a missed frame. Like if you're going along and you're pumping through some kind of analog video on your setup, okay? If you're pumping analog video through over this thing and your video signal's going into your capture device and you don't have this guy, what's gonna happen is, again, there's gonna be a frame that's gonna drop most likely. Again, you're relying on this old technology. It used to happen when the technology was new. What the heck do you think's gonna happen now that it's been 30 years? It's gonna drop a frame, at least. And when it drops that frame, what's gonna happen? Well, again, your image capture device what's it gonna do in that dropped frame? Well, this is gonna build a frame that's ready to insert in that dropped frame if a frame drops. It's also gonna reconstruct the timing and everything on this image, which I'm gonna show you in the example when we're testing here. I'm gonna show you more about the timing. I'm gonna show you some macro vision, which is like old school security built in so you couldn't just rip off tapes and like pirate them and copy them and distribute them. So we're gonna look at that. This will clean up and almost entirely get rid of that security feature of macro vision. It doesn't all the way. So a lot of times people will say, you know, I was recording something and I tried to do a capture and I was only using the TBC and I still lost frames sometimes. Well, or you still had macro vision show up in your occasionally in your image on your captured image. Well, that could be because you have not taken all the macro vision out. This will get rid of a good amount of it, not every little bit of it, but it will clean up. It's kind of like an image cleaner, right? It's gonna clean up the image and get it ready to be copied, okay? So this is important. If you're finding old tapes, we're talking a lot about lost media. If you wanna backup personal files, you might need a device like this. There's a lot of talk that you can get this done into a 4K capture card really good with my cheese new retro tank. And that's probably gonna be even better option at this point if that is possible because it will cost less than these do and be more readily available and have more usefulness to you if that's the case, if that's something that's important to you is actually capturing old video up to 4K or something. This is just going to spit out analog video again. So you still, even with this setup have to have some way to capture the image. Now, what we're gonna do is we're not gonna be capturing any image today. We're gonna be playing all this back on the Sony BVM here in a second. So I'm sorry, I know that was a really boring explanation. I'm gonna give everybody a second in the chat to catch up. Does anybody have any questions? Did that makes any sense at all or did I just sound kind of like a rambling crazy person? Cause I know that can happen. It's, so anyway. We're gonna jump in here. I'm gonna turn this. I'm not gonna use, see the thing about the Toshiba stereo system that you see up there, that's for testing audio playback because there's no stereo, or there's no audio on this BVM. This is a no speaker BVM. So let's go ahead and power it on. You can take a quick look at the JVC, what it looks like when it comes on and turn one of these lights out. Let me see if I can get this set up. I'll do it for a second. All right, I'm just checking my microphone out. All right, there we go. I think I'm online here. I'm gonna turn this other microphone off. There we go. How are we doing out there? I'm gonna give myself a little, ah, sorry, okay, sorry. Sorry to yell in your ear. I just wanted to get the microphone over here that's on the side available. You can see me down here. I've got the mic here ready to go. We're going to see what's going on here. I'm not seeing any image. Oh, that's because I have the data video turned off. So if I turn that on, okay, let's see what we got going on here. First off, let me turn it into regular mode. Okay, so this is our JVC. Hope you can see that. Yep, we can see it on the screen. Good. JVC, just background that you would see on a CRT. Remove that, maybe a little bit more centered. Whoops, sorry. I'll center this up, get that down so you can see more of the image. And what I've got going on here, okay. In the front, this is S-Video. This is stereo audio. And this is the input. The input on this device is on the front here. I do have some down here that are kind of messed up for parts because they have bad problems on the processing board, but this is what the back of them look like. And it is, it's a four outputs for S-Video there and then four composite video outputs and four outputs for stereo audio. And then you have a barrel jack for power in and normally a power switch right there. So that's what the back of this particular one looks like and it's gonna put out the same signal quality pretty much from each one. You might get a little bit better of a signal coming from the S-Video stuff when you're using S-Video, but honestly I've not seen much of an improvement personally through S-Video, through a device like this for like VHS tapes. It's not really been something that I've noticed. Maybe I can turn this camera a little bit this way and we'll see if that'll help and I know it'll kind of get maybe a little bit trippy, but maybe I can do that and kind of tilt it up. There we go, like I can, you know, like, hey, I'm talking down here too, it makes a little more sense. You can see my face. So again, that's where the input's coming in and then it's gonna be going out. And the way I've got it set up right now is it's just got S-Video going in from the VHS player and then S-Video going out to the VCR. Now I've also got composite video. This is a dual output VCR. So I've got composite video going directly to the monitor. So that's the two things I have set up here and that way we can see what the signal looks like when it's going through this machine and when it's not going through this machine, okay? So what I'm gonna do now is I've got a VHS tape in here that's been playing for a while. It's not, I don't wanna get flagged for anything so I don't really think it's going to. This is like a really old copy of Dune and it doesn't matter what it's showing here. I'm gonna show you on HV Delay, okay? Let me make sure I can get that. Maybe if I turn the light out, I can get that looking a little better over here. I'm gonna try to make it so you can actually see what I see. Okay, that's better. I'm gonna turn that down and that'll be fine. All right. So what we're working with now is the actual S video signal. I think, let's see. We can test it real simply. Yes, okay. And this is interesting because yeah, it's not coming through perfectly clear. Okay, so this is the time-based corrected signal. Let me just make sure it's not being interfered with at all by doing that. Nope, maybe it was being interfered with by putting it through double. Okay, so we're not gonna do it like that. We're gonna just show it through there. But do you see here on the screen how you have like these one, two, three, four, five, six, seven, eight blocks down here. And then this is a straight green line, straight black line. This is all straight. And this, you can only see this. This is outside of your normal visible area. These BVMs and PVMs have an HV delay which just delays your sync. So what you're looking at is like the outside image. It's a corner, right? This is the upper left-hand corner of the image. This is the bottom left-hand corner. So you're like going into a middle frame and then you're looking over at the side of that frame. That's what this HV delay is showing you, okay? Now, this is the cleaned up signal. This is the one that's passing through the time-based corrector. When I switch over now, I'm gonna switch over in a second to composite video. Let's see. First off, I wanna plug this back in and see if that interruption takes place again because I thought it was like going crazy there for a second. Okay. So that's again running through the time-based corrector. I should be able to push this and there we go. Look at all this timing stuff and look how there's a big cut here, right? It's not solid. Like, look at this. Perfect solid. This is all synced up nicely. This is again the processed image going through the time-based corrector. Everything's lined up right here. If this is all you know, this is all you really need to know. And this is again something you can only tell with this type of a monitor. But if you look over here, you can see we have a big sync rip and that's most of that macro vision stuff, which you can look up more on macro vision. But that's all put in there to prevent you from copying tapes. That's why if you look, it'll tear sync and things if you try to copy this signal just based off what it has right here. Okay, it's built in there to make it hard to reproduce. And then this is all timing, right? This is telling the image and the tape. You know, this is timing up things with the VCR. This is how everything's getting timed up with the audio playback from the tape as well as the video. It's all based on these. So what happens is these timing notches and timing signals can get of course get warped or get screwed up. It's very complex, you know? So then again, if you put it through that machine, there's the same signal sent through there but you could still see. We're still probably getting a little bit of this macro vision. Like I said, you're getting rid of 90% but not all of it. But that's a lot cleaner. So this makes it to where you almost can just basically go in and copy this or back up this image once it's been passed through this time-based corrector. So what I was testing here today is I need to test the video signals on here. I need to test all the outputs and see if there's actually a difference. Hey Belmont, welcome in. I need to test all the outputs here and see if there's actually any difference on the video. Right, local age. CRTs can pick, CRTs can sync to a lot more things than like capture cards. Man, capture cards, for example, will throw an image out. And so it's same thing. This kind of stuff was sent through on TV broadcasts back when there was analog video sent over the air. Now it's what, it's like, there's all this stuff now. It's like HTCP or whatever it is, the stuff for HDMI, that kind of signal on modern television. But anyway, that's how it looks when it's cleared up. And so this way you know, right, you know this device is working. Hey Andre, good to see you. Thanks for coming in everybody. Again, if you're just showing up, been going for a little bit here, please drop a like for the algorithm and I welcome you in, thank you for coming. But again, cleaned up image here and that's as video. And then if I go over here, there we go, straight from the raw signal. And like, you know, this CRT has no problem catching that signal, but if you try to run that through a device, trying to copy it, it just won't work. The interesting thing is again, if I flip through this signal, I notice, which one is that? So I did have the customer say that the S video signal looks darker. I do notice that you can see that kind of on this screen, it's going to be hard. Maybe if I push stop, I don't really want to stop it. But as I'm cycling through this, the composite straight from the player is a little bit brighter. Now it's not a huge amount of brightness, but that can make a big difference on a playback. And that is most likely from the analog video board. So yes, that's probably because the caps are bad. That's what we're thinking. What I'd like to do, I am seeing a drop in that. We might pull the device out and see about doing something else. I really don't want to get flagged for copyright. I doubt that's going to be good enough reproduction on there. But it's interesting how that all brightens up too when I switch over to this signal. Like that does look a little bit more saturated, a little brighter, that looks like a little darker, maybe a little sharper. But I don't think it's hard to say. Like this is not one that's obvious. And it's hard to, this is what I was trying to convey to the customer. It's hard to say that this issue nowadays, you're not just dealing with having to restore the time-based corrector, but it often depends a lot of times on the hardware you're using to back up the video. A lot of times people will use things that are also time-specific or needing restoration themselves, like old PCs that could be 15 years old now that are in need of work themselves. So what we'll do is I'm gonna try to put it over in back in non-HV mode. We'll go back to side-by-side so that I don't get flagged. I mean, that'll be hard for them to see. What I'm gonna try to do is turn some. This tape is actually the funny thing. The reason I have this tape in here is it is one of the like craziest tapes I own. Let me see the details on this thing. It's this dune tape, right? It's ridiculously long. And it's just a single tape. I can't remember why isn't it two and two. 265 minutes and it is not good, like not high quality. 265 minute long tape plus it has previews on it. So it has like five to 10 minutes of previews before that. So it is an extremely ridiculous tape. So I'm gonna turn the brightness back up. Whoops, I think I might have hit the rewind or stop button there. Let me turn to stop that awful little bit. We're gonna go back here and try to get things balanced back on the picture for a second. And then I'm going to see, I'm getting some weird like color things, right? Is that through the, let's try and, it's hard to say that, so that's through the device. All right, let's check it out. We're gonna go, I'm gonna press play here again. This is just straight through the device and I'm gonna start switching up outputs on the back of this. And I'm gonna see if I notice any kind of difference in picture quality or not, as I change it. Not the most precise test, but I'm not getting like a, usually when they don't work very well, you get like zero picture out of them. Like very dark, very much darker than this. Okay, I'm not having much of an issue with the S video out. It all looks consistent. Let's try now. I'm gonna switch over and just use composite video out now. That in there, switch over here. Wow, so that might be a lot different, right? Let's see. I've got composite video out plugged into one. Now they're the same. See that's composite, that's S video. It's a little darker. I think I mentioned like composite, S video. Composite, S video. But those signals are coming out of the data video. Interesting. But both the signals now should be time corrected. Got timing corrected there and there, yeah. I mean, it's not really showing a big difference in quality, as I said. Now, if I turn this off, it should show the VCR. If I turn that off, what does it show? It should show color bars sometimes. I don't know, not always. Okay, no color bars for me. That's interesting. See, now this is something. See, normally it would show color bars right there. Let's see if we unplug the input. I should see some color bars here, I think. But instead I'm seeing nothing. I'm seeing like some darkness come up on the screen but nothing else. See, like there should be a color bar. So this has got a problem where I think it's missing. Oh, man, I think it's missing the TBC pattern. So that might be an issue. So let me throw it on. Like I've got another one here that doesn't work. Let's see what it looks like. So this one, all right, I'm gonna plug another one in. Now, this one should show a terrible pattern on it. But, let's see. Does it have an island switch? Yeah, it's turned on. So this one should show a pattern possibly. Hopefully, let's see. I mean, it's the same power. It's got power. Okay, so it doesn't seem to show it continuously. Okay, but you did see it come on there for a second. Let me, maybe it's not just showing up quick enough on the computer, or from the computer onto the video. See, this is, I have another one here. I'll turn it on and show you what's going on with it. I can't get it to work at all. Look at this one. It's got really crazy. I'll put an image into it, you can tell. Let's send in some, see, look how bad, this one's wage act up. And that's coming from the card itself. This card's messed up like the card I was showing you earlier that looked like the graphics card. That's what it looks like. And you can't do anything with that. That looks terrible. That's what it looks like when it plays things back. The funny thing is, it's still correcting the timing on this thing, but it doesn't, something's wrong with the playback. I've not been able to figure it out. Um, that's how that one looks. That's what, if it looks like that, if you get like streaks through the image like that, I can't fix that at all. I've not been able to figure that one out. That's kind of the deal with the time-based correction. Right? Okay, you kind of get a better idea for it. I mean, that machine works properly. And clean is up the image. Now, the problem is these things were not built to last, and we're not built to last 25 years, and that's what we're pushing as far as age on a lot of them. So, that's pretty much it for the big main topic in today's stream. Just wanted to come in and hang out, has everybody else doing? I haven't seen anything going on for a while. I can click the jazz back on. We can hang out for a minute. We can call it a stream and get on to the next thing. All right. Everything looks to be going good so far today on the stream since we actually went live. I want to, the next stream I've already been preparing for it is gonna be on how to order capacitors. I'm gonna go through, and I talked about this last time a little bit more. I'm gonna go through, we're gonna order capacitors, a stockpile of capacitors. Okay, so that will help you, you could set aside about a hundred bucks and get just about every capacitor you're gonna need and a good amount of them to start off for your shop or something, for example. So that's what we're gonna be working on next time. Oh yeah, the Duke's Dunk. That's all right. The first part is, is the team's just going transfer and so is the coach. The coach took the job at Vanderbilt. Yeah, absolutely. So I'm gonna do that. I'm gonna do, we're gonna do the cap kit. I've already got the thumbnail made for it. I've got things set. We'll do the cap kit shopping. We're going to, I'll make the cap kit so that after the show is over, we can get that shared around so you can actually order the one we make. We'll do only, we'll do only top brands. Of course, if we do that, the whole thing is gonna probably sell out. The cap kit that we make will probably sell out after about 15 people buy it. Like, cause that's what will happen. A couple of items will go out of stock and then we'll be looking for a new part to replace it with. But today, yeah, I'm gonna jump on if you guys wanna see more stuff. I'm just a little confused on this thing cause it's not really acting that tough, that terrible. I might switch out a board on it. That's the video board to see if that changes anything at all cause if it doesn't, I'm not gonna be able to really fix this one. But this time-based corrector, I don't really see it doing anything wrong. It might be something else in the guy's setup. But anyway, we'll get to that cap kit thing. Don't get it all going next time. I really appreciate y'all for being here and hanging out with me today on kind of this chill stream. Short stream, I mean, still 35 minutes and had a good time. Glad to always check in with everybody. Hope you have a wonderful day. Yeah, driving up prices of capacitors. There we go. Don't. I don't think we can make a dent there. But I will show you that. I'll show you how to save some money there and build up a nice pile of capacitors. So be on the lookout for that next. Everybody have a wonderful day. I'll see you in the next stream. Thank you again.
