[00:00] There's a misconception that movies shot [00:02] with digital cameras [music] and those [00:03] shot with film cameras work in contrast [00:06] with one another. That one process [00:08] [music] negates the other. Like you're a [00:10] film person or a digital person. But a [00:12] movie shot digitally [music] can be [00:14] printed and projected on film. And a [00:16] movie shot on film will very likely at [00:18] some point go through a scanning process [00:20] [music] [00:21] for at least digital effects and [00:22] editing. And with IMAX, both ends of [00:25] that equation, the scanning and the [00:27] recording of large format 70 mm film [00:30] require purpose-built equipment and an [00:33] experienced [music] [00:34] technician to operate those machines. I [00:36] visited the 70 mm film scanning and [00:38] recording labs [music] at IMAX [00:39] headquarters to watch these machines in [00:42] action, including one of the most [00:44] beautiful bespoke machines I've ever [00:46] [music] seen, this film scanner that has [00:48] scanned almost every single IMAX film. [00:52] Hey, Fred. Hello. Such a pleasure. [00:55] Likewise, thank you. Um okay, so this is [00:57] the old scanner, and that's the new [01:00] scanner. I have so many questions about [01:02] this, but I want to just start with like [01:04] how long have you been working for IMAX? [01:06] I've been working for IMAX I'm in my [01:07] 15th year now. [01:08] >> 15th year? Have you been scanning for [01:10] them the entire time? [01:11] >> Scanning and film recording. Amazing. [01:13] >> So, if you have a piece of IMAX film and [01:15] it needs to be a digital image, that's [01:17] me. [01:17] >> That's you. And if it's a digital image [01:19] and you need a piece of IMAX film, [01:21] that's also me. [01:22] >> Amazing. Okay, so I I we're going to [01:24] talk about the process [01:26] uh that film goes through in your room [01:27] here. But I right off the bat, I walk in [01:31] and I see a machine with a marble [01:33] countertop and these space-saving holes [01:36] and chrome polish, and then I touch it [01:38] and I'm like, wait a minute. Cuz cuz [01:41] Greg said outside that this was one of [01:43] This is serial number one of this [01:44] machine. [01:45] >> This is number one. This is the only 65 [01:47] mm [01:49] scanner that that this company built. [01:51] Well, dude, whoever made this [01:52] >> 35 mm scanners afterwards, and they made [01:55] like, I don't know, pile of them. But [01:56] this is the only one for 65. [01:58] >> Okay, but whoever made this is an [02:00] important artist. Yes. Okay, you agree. [02:03] This is a masterpiece. [02:05] >> Yes. Yes, sir. [02:06] >> Oh my gosh. And then when you were [02:08] calibrating, I watched this whole thing [02:09] move or there's all these servos inside [02:11] here. Yep, motors and belts and you [02:14] can't lift the hood because it's [02:16] granite. And it's made granite so that [02:18] it's super stable so that it's [02:19] measurements are the same. OH MY GOD, [02:21] IT'S NOT even just aesthetic. It Yes. [02:24] It is [02:26] temperature. Uh because a few degrees in [02:29] temperature can change you know, metal [02:31] will change a little bit and that'll [02:33] throw this whole thing out of alignment. [02:34] So they built it on granite, polished [02:37] granite. Because you're scanning pixels [02:40] and you can't have any variance [02:42] whatsoever. We are scanning a frame this [02:45] big. [02:45] >> Yeah. [02:47] And how many pixels is that total? [02:48] >> And we are scanning it at a over 8,000 [02:51] pixels across. [02:52] >> Crazy. [02:53] The way this machine was set up is it [02:55] only does a vertical line of pixels at a [02:57] time. Okay. [02:58] >> So it's slicing the image 8,424 [03:02] times per image. That must [03:05] That must take a while. [03:06] >> put 12 and 1/2 seconds. [03:08] >> 12 and 1/2 seconds per frame? [03:10] >> Per frame. So every IMAX that's ever [03:13] been scanned went through this scanner [03:15] until Until VERY RECENTLY. YES. [03:17] >> WOW. THAT IS A [03:20] That you kind of have to work backwards [03:22] from deadlines and deliveries just to [03:25] ACCOMMODATE THIS. [03:27] >> YES. [03:28] WOW. [03:29] >> YEAH. Is this machine was semi-retired [03:32] at this point? Is it emeritus? I'm [03:34] sorry, it is very [03:35] >> [laughter] [03:35] >> very much semi-retired. I do test it, [03:38] you know, weekly to make sure that it's [03:40] still running because this is our [03:42] backup. [03:42] >> Right. If this goes out, this This is [03:45] it. Now, the nice thing is we haven't [03:48] had to use it. Right. [03:49] >> This has only seen me testing it for [03:53] a year now. Or a year? All right. [03:55] >> So it's not actually been in production. [03:58] It's such a [03:58] >> is capable of being being that 25 years [04:01] after it was made. For a machine. I [04:04] mean, there's a way in which I can tell [04:06] that the people that put this together [04:07] love machines and also love products. [04:10] Yes. [04:11] >> Like they weren't just making a one-off, [04:13] they were making it a beautiful product. [04:16] >> Yes. This is inspired by I feel like [04:18] German manufacturing from mid-century, [04:21] from Scandinavian. I mean, it's like [04:24] there's so much. Wow. Yeah. Okay, now [04:27] let's talk ABOUT THIS PROCESS. [04:28] >> [laughter] [04:29] >> LET ME PUT A PIECE OF FILM ON. OKAY, NO [04:31] MIND. SO, [04:33] take a piece of film and we thread it [04:36] up, starting this side. [04:39] It starts Make sure it doesn't want to [04:40] walk away on us. [04:41] >> Fair. [04:46] Make sure we take a few up, a few rolls [04:48] laps up on the on the roll. [04:50] And then [04:52] I like to pull a little bit extra and [04:54] thread it through here. So threading up [04:56] the gate first so that it sets correctly [04:58] and then with the sprockets, [05:01] make sure it locks in place. [05:04] So I just want to highlight here for a [05:05] second like, you know, film is all about [05:08] the fast shuttling and with precision. [05:11] Yes. [05:11] >> That's got to be an exponentially harder [05:13] problem at this size and scale, [05:16] especially for tiny variances of [05:19] sprockets, which I would imagine you [05:20] guys have reduced as close to zero as is [05:22] humanly possible. [05:23] >> Exactly. And that's why you may notice [05:24] the film path is very precisely defined. [05:28] I'm not making loops. I'm not making [05:30] approximately the right size. I'm going [05:32] it fits right here, it fits right here, [05:34] and everything lines up exactly. [05:36] >> So this machine knows what to expect [05:38] when this piece of film is through that [05:39] sprocket hole and when it's going to get [05:41] over here and it's never wrong. [05:43] >> And it's never wrong. [05:44] So, [05:46] then [05:46] >> Oh, and now it goes through all these [05:48] things. [05:48] >> all all these things. So, [05:51] there is, I believe, a an edge code [05:54] because film comes with uh from Kodak [05:56] comes with a an edge code printed right [05:59] into the film. Oh, okay. [06:00] >> It's a latent image until obviously they [06:02] process the film. Unfortunately, this [06:04] one does not work, never has. So, it's [06:07] there. It was there with the idea of [06:09] making it work, but it never did. [06:10] >> Copy. [06:11] >> So we go around there. These two [06:13] basically are controlling the tension. [06:15] How much tension do do we take up? [06:17] >> I see. [06:17] >> And And watch when I spin it up, see how [06:20] that Mhm. [06:21] >> And it'll find a balance. And as the [06:23] film is transported, it'll make sure [06:25] that this thing's pulling at the right [06:26] amount, even if the roll's really big or [06:28] really small. [06:29] >> So that it's never winding it too tight [06:31] or too loose, it's always at a specific [06:33] >> Oh, exactly. Wow, of course it has to [06:35] be. Because too loose and your film goes [06:39] on the ground. [06:40] Too tight and you risk snapping the film [06:43] or [06:44] pulling the film past the the sprockets [06:46] and creating problems that way. [06:48] >> I cuz if film is surprisingly brittle. [06:51] Yes. I remember as a projectionist, I [06:53] remember having one smacking around and [06:56] creating a lot of celluloid confetti. [06:58] Yes. [07:00] >> [laughter] [07:00] >> When we get into film recording, I'll [07:02] tell you about chewed-up film. [07:04] >> Okay. [07:05] >> Cuz those machines like to chew film [07:06] occasionally. So do you only do tension [07:09] on the take-up side? [07:10] >> let me do this side as well. It's the [07:12] same thing just in reverse. [07:14] Or this. [07:15] Go around this way. This way and then [07:18] pull tight. [07:20] And that lets it find its level. [07:22] >> gate closes when I DO THAT. [07:23] >> OH, WOW. [07:25] >> It automatically knows, oh, I got [07:26] tension on both sides. That means I can [07:28] try to close the gate. That's some [07:30] really nice user experience right there. [07:32] >> When the gate tries to close, if it [07:35] can't pin that one Yep. and that one [07:38] >> Yep. [07:38] >> Those pins actually go through the film [07:40] from the other side to hold it in [07:42] position. Yep. If they go if if [07:45] everything's not lined up correctly, [07:47] they will try to pin through the film. [07:48] Very gently, they'll do it and they'll [07:50] stop. [07:50] >> won't poke through it. [07:51] >> And they'll go, nope, there's something [07:53] there. Nope, you know what? Forget it, [07:54] I'm not doing this. So it's not going to [07:56] punch a hole in your film. That's [07:58] beautiful. [07:58] >> 25 years ago, [08:00] somebody made this brilliant decision [08:03] that has saved so many rolls of film. [08:05] >> If any of the people that worked on this [08:06] is watching this video, reach out to us [08:08] in the comments cuz I want to talk to [08:10] you about this thing. Do you even This [08:12] this beautiful. These these circles and [08:14] lights here. [08:15] >> It's almost a face. It Oh, there there [08:17] is. It's almost a little like a droid. [08:19] Yeah. [08:20] Okay, so now the film is loaded up. So [08:22] once it's loaded up, I try to make sure [08:24] I I will advance a frame, a couple [08:26] frames just to make sure that it is [08:28] actually going to transport correctly. [08:31] Like that. [08:32] >> So that was one frame. [08:33] >> Those This is one frame. [08:35] Gotcha. That's moving 15 perfs. [08:37] >> It's moving 15 perfs at a go. Okay. And [08:40] as you can see, very smoothly. Yep. Yep, [08:42] through custom etched and machine [08:44] buttons that didn't get bought in a [08:45] catalog. Right? [08:47] Yes. [08:47] >> [laughter] [08:48] >> Then I'll wind down to the beginning of [08:50] the roll because this is leader for [08:52] handling purposes. That way I don't have [08:53] to handle people's film. [08:57] And if we look through here, [08:58] >> Oh, yeah, see the color test. [08:59] >> see the We can see the picture and I can [09:01] actually make adjustments to [09:06] Oh, I can go one perf at a time so that [09:09] I'm in frame. Gotcha. So that's the one [09:12] perf jog. [09:13] >> Yes. Amazing. Which is stop plus [09:16] forward. I can also, of course, do stop [09:18] plus backward to go the opposite [09:19] direction if I need to. [09:21] And we are almost ready to scan a frame, [09:23] but before I do, make sure I take the [09:25] calibration strip. [09:26] Oh. [09:27] >> scan like that, but it will not look [09:29] very good. So What does the calibration [09:32] strip do? It's a color calibration? [09:33] >> It's It's a color calibration and it [09:35] basically emulates the unexposed film [09:37] that is processed. [09:39] We call it the film base. Gotcha. [09:41] >> So it is [09:43] just a piece of clear Right, that is [09:46] sort of the neutral of film. Yes. And [09:48] yes, it's a little scuffed up. It's been [09:50] used many years. [09:52] >> [laughter] [09:52] >> The fact that it's here and not here [09:55] throws it so far out of focus, you don't [09:57] the blemishes or what have you. [09:59] >> the blemishes don't matter. Speaking of [10:00] which, one of the things that we do in [10:02] this room is we have to control the [10:04] temperature and humidity very tightly. I [10:06] would imagine the humidity could affect [10:07] image quality, right? Humidity will [10:10] cause the film to warp. [10:12] The IMAX frame is so big that it [10:14] actually can warp as it goes into the [10:16] gate and still feed through the machine. [10:19] Is it because the celluloid is slightly [10:20] hygroscopic, it absorbs a little water? [10:22] EXACTLY. [10:23] >> WOW. [10:23] >> EXACTLY. [10:25] And we've had [10:26] we've experienced it where it's like we [10:29] scan something then when we scanned it a [10:30] couple days later it's like, wait, why [10:33] is it a different focus? Wow, that's [10:35] amazing. [10:36] >> Let's We really jumped on it, made sure [10:38] that everything was [10:40] properly set up and So then temperature [10:42] and humidity control is part of the [10:44] calibration process of this room. Yes, [10:46] and that's why you hear air running [10:48] continuously [10:49] >> in this room. So you got a lot of [10:51] hoodies and fleeces. You make sure [10:53] you're buttoned down warm and you [10:55] [laughter] take care of the all of that [10:57] you make sure that that's good. Um and [10:58] this is the business end of the scanner [11:01] coming through this way. Uh so the light [11:02] column is here, the light is underneath. [11:04] Gotcha. Goes up and I think they use a [11:06] prism or a mirror and deflect it into [11:08] the camera which is here. Gotcha. Um And [11:12] it is a linear array so it's not taking [11:14] the entire picture at the same time. [11:16] It's taking [11:17] one set of pixels vertically up to 6,144 [11:20] [laughter] [11:22] pixels vertically. So the scanner is [11:24] just basically one pixel wide and film [11:27] frame tall. Uh ish [11:29] >> Yes. ish Exactly, yeah. [11:33] 12 and 1/2 seconds. [11:34] >> 12 and 1/2 seconds. [11:35] >> I I'll be frank, knowing what it's [11:37] trying to do that sounds fast. [11:40] But it also sounds slow. [11:42] >> Incredibly slow. [laughter] When we look [11:43] at the other machine you'll be like, [11:45] that is very very slow. Um can we just [11:47] able to actually just witness a scanning [11:49] sequence? Um yes, let give me a moment [11:52] to set that up. [11:53] Oh, one other thing you you hear the [11:56] hear the hiss? Yeah. That's actually we [11:58] actually have air knives on it. [12:00] Partly to blow off the dust, partly to [12:03] keep the film, you know, moving in it [12:05] smoothly. Right, right. Where are the [12:07] air knives? Are they here? [12:09] >> They are actually in this. Right, right. [12:11] Okay. [12:11] >> So with if there was no film in the gate [12:13] I could show you you could stick your [12:15] put your hand in the gate and see [12:16] actually feel them. Gotcha. Uh but the [12:18] whole goal is when it's here no dust has [12:21] been able to get anywhere near it. [12:22] Exactly. Uh I really appreciate you [12:24] walking me through this. This is it's [12:26] it's amazing. Let's talk about this [12:28] brand new one. Yes. [12:30] So what's the biggest difference between [12:31] the new machine and the old machine? Is [12:33] it just speed? Part of it speed, part of [12:36] it is the process that it takes the the [12:38] image. Mhm. Um the old machine took it a [12:41] single vertical line of pixels at a [12:43] time. This actually will scan an entire [12:45] frame except of course a gigantic frame [12:48] like an IMAX frame because an IMAX frame [12:51] is so big. So it actually scans the IMAX [12:53] frame in thirds. Oh, so it does 1/3, [12:56] middle third, other third. Yes. And it [12:59] does its own stitching of them? Um no, [13:01] we actually do that on a separate [13:02] machine. Oh, amazing. [13:03] >> We could do it on the separate on the [13:04] same machine but it is a separate [13:06] process. [13:06] >> Gotcha. [13:07] That allows us to do a little bit of [13:09] extra work if we need to do some [13:11] processing or something like that in [13:12] between. Okay. And this one you may [13:15] notice threads up the opposite direction [13:17] from the the other machine. Goes right [13:19] to left. [13:20] >> It goes right to left. [13:22] Apparently if we went left to right this [13:24] whole apparatus would be have to be [13:26] upside down and this whole big thing [13:27] would have to stick up in the air. So [13:31] >> Yes. That's so funny. [13:32] >> Because I was I was freaked out that [13:34] it's horrible when you have to scan on [13:35] both machines at the same time. [13:36] >> Oh cuz you're going back and [13:38] uh yeah. [13:38] >> and forth and you're like, which one is [13:40] wound the right way? Sometimes you just [13:42] have to stop and just yeah, I can [13:44] imagine. This is where being on the [13:46] computer helps because on the computer [13:48] forward is always forward, backward is [13:50] always backward. [laughter] [13:51] Okay. [13:52] >> So the setup is actually similar here as [13:54] you do a rough setup and then you do the [13:56] spool winding. Exactly, yes. Then fill [13:58] in the details as it were. [14:03] That's [14:05] There we go. And this one also has [14:06] tension arms. Gotcha. [14:09] Some things don't change. You always [14:11] need tension arms to make sure that the [14:12] motors on the [14:16] on the rolls of film aren't taking up [14:18] too tightly or too loosely. And your [14:20] goal is that each tension arm is [14:21] vertical. Roughly. It they au- [14:23] automatically will you know, they'll [14:26] stop if at a certain point. I go mostly [14:28] go approximately the right place, [14:29] sometimes a little past and then they [14:31] stop cuz that's where they need to be. [14:34] It's called reader. We can read the key [14:36] codes that are that Kodak puts on the [14:38] film [14:39] and that way the editorial people can [14:41] tell us scan these exact set of frames [14:43] and we can say [14:45] okay, wherever it is on the roll find [14:46] it, scan this. [14:47] >> Well that makes that process much [14:49] faster. [14:49] >> makes it much faster and very accurate. [14:52] Okay. [14:53] >> So instead of having to take those [14:54] numbers and go, okay, what's the number [14:56] at the beginning of the roll, do these [14:57] calculations, how far down do I have to [14:59] go? [14:59] >> And then go ahead and pick. Exactly, [15:01] just find it. [15:02] So that's kind of what we have for the [15:05] setup on that. And again notice it is a [15:07] vertical operation rather than a [15:09] horizontal one. Uh hence the glass doors [15:11] and the dust mitigation. But it's [15:13] effectively the same machine just more [15:15] than an order of magnitude faster. Yes. [15:20] Dude, I [15:21] already just in the last 10 minutes here [15:24] my mind has been blown like three or [15:26] four times and it's all about the scale. [15:28] The scale of this frame of film is is is [15:31] diabolical in terms of all your [15:33] processes with it. Yeah. This is [15:35] scanning. You guys also do a lot of [15:37] recording. What's the other part of this [15:39] process? Can we walk through that? [15:41] >> you don't have film and you need film. [15:43] Let's do that. [15:44] >> Okay, good. [15:45] All right. This is film recording. Yes. [15:48] IMAX has been around and has been [15:50] scanning for a long time. So this is [15:52] real legacy equipment back to the early [15:54] days. It is. If you remember the Silicon [15:57] Graphics machines [15:58] >> Yes, very well. Yeah, we used those to [16:01] run these machines. [16:02] >> Oh, hilarious. Good god, I remember one [16:04] year at the ILM Christmas party that was [16:06] actually the door prize for best costume [16:08] was an O2 workstation. Nice. Okay, so [16:11] what is the technology that is used to [16:13] get the image the digital image printed [16:15] onto the film? [16:16] >> So to get the digital image printed on [16:18] the film in the base here we have [16:22] obviously boards and stuff that run that [16:24] run this. But the big thing is the the [16:26] tube. The tube? [16:27] >> the We literally have a cathode ray [16:29] tube. [16:30] >> What? Like the old tube tube TVs but way [16:33] more advanced obviously. There's a CRT [16:35] at the heart of the scan of this [16:37] printer? There is. So obviously the CRT [16:39] machine gives you the precision that [16:41] you're looking for on a pixel by pixel [16:43] color fidelity by color fidelity basis. [16:46] Yes. [16:47] >> That's astounding to me. [16:48] >> Exactly, yeah. Um does it do it in a [16:50] mono color and then you use filters for [16:52] the color? We do indeed, yes. So the [16:54] tube itself is is a particular white and [16:57] then we run it through some filters. So [16:59] we have a We don't use the clear filter [17:01] but we could if we needed to. There's a [17:03] red, green and blue filter. I'm going [17:04] backwards here. That's the blue filter, [17:06] the green filter. So it's like the old [17:08] the old three strip process reversed in [17:11] order to obtain the imagery. That is so [17:14] cool that the CRT provides the precision [17:17] that you need. [17:18] >> Yes. [17:19] So [17:20] this is the tube. [17:23] And as you can see it is rather big. [17:25] God. The piece the piece here at the end [17:27] >> Yeah. is what they call the thick glass [17:30] because if dust settles on the tube [17:33] you have a problem. It sits there the [17:35] entire time and you have a speck [17:38] on your movie. [17:40] And if the camera pans, you know, the [17:42] the [17:43] >> [clears throat] [17:43] >> the speck just sits there and you can [17:45] totally see it. So they the way to do to [17:47] avoid that was that they came up with is [17:50] to put a big really thick piece of [17:51] glass. More than half the weight sits [17:53] just in this glass. Wow. And it puts the [17:56] the piece of dust if there is one way [17:59] outside the focal plane. [18:02] Oh, that's brilliant. That's so [18:03] brilliant. Yeah. [18:05] So you guys are are printing on the same [18:08] kind of reels like two, three minutes at [18:09] a time? Yes. What is the how slow is how [18:12] good I was not going to say how fast is [18:14] this. How slow is this? [18:15] >> So once upon a time we could get a lot [18:17] better speeds but with the CRTs as they [18:20] age they get dimmer and we have to [18:22] expose the image longer in order to get [18:24] the same exposure. [18:26] >> Am I correct that all the CRTs that have [18:28] ever been built for this are already [18:30] built and you're just grabbing new old [18:33] stock where it shows up? [18:34] >> And seeing if we can get them [18:35] refurbished which is a job [18:37] unto itself. [18:38] >> Oh my, can't even imagine. These are [18:40] technologies that are rapidly their [18:41] support structure is disappearing all [18:43] the time. It is, yeah. So they get [18:45] slower as they age. [18:46] >> Yeah. Currently we're running somewhere [18:48] between a minute and two and a half [18:50] minutes per frame. Oh my gosh. You [18:52] thought 12 and 1/2 seconds was slow? [18:55] A minute to a minute and a half. Um and [18:57] this is so like Christopher Nolan shoots [18:59] on film, he brings a couple of different [19:01] shots that need a an effect done to them [19:03] that is executed on these. [19:05] >> Exactly. Incredible. My joke is [19:08] I got tired of watching paint dry. [19:11] Grass grew too quickly [laughter] for me [19:13] so I went into film recording. [19:15] Hilarious. How many backup CRT tubes do [19:20] you have in stock currently? [19:22] How about the other question? [19:25] >> [laughter] [19:27] >> I have like seven machines in the room [19:29] and about four of them are working. Oh [19:31] my gosh. [19:32] >> Because of the CRTs. Um so I I would [19:34] imagine there are people working on [19:35] solving this problem currently. Yes. [19:38] >> Okay. There are various solutions by a [19:39] couple different groups trying to find [19:41] basically find replacements for the CRT. [19:43] Because this still exceeds the precision [19:45] of anything currently being built. And [19:47] reliability. You want something that's [19:49] not only precise but is reliable that [19:51] you can put a thousand feet of film, do [19:54] it a frame at a time, and 4,000 frames [19:56] later [19:57] get it processed, look at the print, and [19:58] go, "Yep, that looks good." Amazing. [20:01] >> Every time. Um I notice it's freezing [20:03] cold in this room. You're way colder [20:05] even than in the other in the scanning [20:06] room. [20:07] >> That's a little bit accidental. It's [20:08] supposed to be the same temperature and [20:10] humidity as the other [laughter] room. [20:12] Um because we used at one point we used [20:13] to have 18 of these machines. If you can [20:15] imagine 18 of them packed into this room [20:18] You needed to pump a lot of cool into [20:20] here to keep them all running optimally. [20:22] Exactly. Wow. [20:24] >> So, we've made some adjustments to the [20:26] temperature to accommodate for fewer [20:28] machines, but it's still cold. So, in [20:31] this day and age when some filmmakers [20:33] can leave critical decisions about a [20:35] shot up until days before the film's [20:37] release, they must have a rude awakening [20:39] when they come to you guys for post. I'm [20:41] sure they do. [laughter] I'm hoping that [20:43] they go, "Oh, okay, let's figure this [20:45] out. Let's make sure that this works." [20:47] Well, I mean because the deadlines are [20:49] real deadlines. Um this has been such an [20:52] eye-opener. Uh thank you so much, man. [20:54] This is [20:55] incredible.
