 other equipment those things we can very useful we can take those isolated sounds and isolate them and put them on separate tracks and build up you know what would sound realistic in the end to the audience and as I said crew comments this sort of thing you can also use the tape as kind of a diary because the tapes are inexpensive it's not like shooting the IMAX film or you know so many dollars per second of film you have to use it very wisely I believe you're taking a dozen cassettes with you which is something like 12 hours of time which is a lot of material so I wouldn't be concerned with all the things you have on your minds to try to set up a shot and get the camera you know the sound just ready and then have somebody start this and run that that's going to be just too much to worry about with these cassettes you can set this up maybe even record a rehearsal for a shot when the camera is not running because you could get them some of the sound without the camera for going we can maybe cheat that sound later Quality standpoint, how good a quality is that tape have to be before it's used? well this is a kind of well we this machine this is a commercially available cassette recorder right and its operation is very simple it's similar if you have a cassette at home or in the high-five system it's very similar to it it is a very high quality cassette recorder it's about as good as you're going to get and certainly within this size package and simplicity of operation you're not going to do better and we've recorded lots of material on a machine like this in the studio to use in regular films so it can be very good and that is the frequency response that this machine will pick up with these microphones is full range okay and it's not just a documentation device in the sense of getting a record like a log tape would be this actually can make recordings which can be aesthetically usable we'll talk about putting voice information on the tapes a little later because once again it uses a diary you put a tape in you can save the time and identify the situation you can talk all you want you'll find the most sound men end up talking to themselves a lot of time partly because they're driven insane in their work and partly because it's a it's a good way to you know keep a diary often you want recording will say well I'll remember later what I just did or what where I was but you won't and weeks later you'll pour through your tapes and you just hope that along there there's there's IDs and times and you know any information you want any home unit that you might encounter you can see once you run the tape and I'll just put it in play you can see that the wheels are turning they fortunately they've prevented the ability to pause on this machine do you want this recording to be Dolby or non-Dolby which is this electronic way of encoding information on the track the answer is yes and so well you know it's keeping the Dolby position if you accidentally had it in the non-Dolby Dolby position it wouldn't destroy your recording it wouldn't be quite as high a quality this this switch here is depends on the type of cassette you buy just like film stocks you can have sets with a different sensitivity option down here is a pad really if you were going to record something amazingly loud rock concert up close or diesel engine by something enormously loud this is essentially switches a set of resistors into the microphones desensitize them a great deal you wouldn't have to worry about this you won't be recording anything that will require that type of precaution if I was able to give full attention to the sound unit I would turn them off after a session yes okay you know if we don't don't worry about it if you get remember the next day don't worry about it you're gonna have to think about changing some about it my instruction would be to turn it off what I'm saying is if you forget too busy there's probably not going to be a serious problem ordinarily when I pack the unit up at the end of a session I turn everything off and put it in case in a week later I pull it out and I knew it's all but yes you should turn it off once again there's two microphones because there's two separate input channels and more or less the way we've used this recorded on the flight is not to make a stereo recording in the sense of you know two microphones up close one left here and one right here but rather separating the two such that they both can get a perspective on different items you know and using this rather as a two-channel recorder rather than trying to just get a single stereo image you could have one mic down on the mid-deck ceiling and one up above in the flight deck depending on what you were doing so we'll talk a little bit more about placing microphones later but think of it as two tape recorders they'll always still record on both channels simultaneously you can't stop that every time you go into record both both channels record but it think in terms of how how broad you can make your coverage of things interesting items recording it's strictly a monitoring gain control so if you have headphones plugged in here if you happen to take an adapter and you use your other headphones you can listen to the volume here if there are no headphones plugged in this monitor control controls the loudness of the speaker and playback so the signal on here you can just output game control that I have such meters on yes I usually as I hear noises I adjust it so that it's kind of bouncing into the red but it's not banging and living over red is that exactly the right procedure yeah what what you're the only judgment you're gonna make it set on this instruction here what full counterclockwise well that would mean that these are up sorry this way fully which would mean they're assuming the way you're going to record is a lot of quiet little noises most of the things you're recording are dialog you know there's a mic in the let me ask you have what's called a limiter down here which I assume suppresses the signal when it gets to itself it's a ceiling on things so the green dot is on yeah they are that's what you want well usually in recording I don't recommend people use the limiter but that's in cases in which the record is at the game control and he can make a judgment as things occur as you can see something really loud is about to happen and maybe he's rehearsed it he knows he can break it now crank it down with the limiter on what will happen is he will not make those judgments for you but the limiter will do is we will put a ceiling on things such that if you were recording a normal dialogue scene and it's something there was a big noise somebody dropped something a something to be dropping somebody bangs a piece of equipment slams the door it would tend to suppress that noise a little bit everything would kind of dip down for a second and snap back that's something you'll have to decide upon yeah if difference that's dialogue on the given setup and probably once you've kind of set it up in the flight deck where you are it's you probably have found about the right spot things are gonna change I'm guessing you're gonna be kind of in the mid-range here such that once in a while a loud noise will peak it but most of the time you're safe and things are staying there is a lot of meter action but it's not hanging in the red you're allowed to go into the red just don't loiter that's fine you can get the kind of sounds you're gonna you're gonna hit are about abrupt sounds I mean the safest thing you have to read out on I'm just in safest thing you may get a better recording without it so I can't tell you know now that you say that we can set this thing up and it's running yeah you get busy for about 10 minutes we're not even watching the meters and all the sudden noises are louder than we thought when we're setting it up yeah and we could be banging the heck out of the machine and so by having the limit are on yeah that's your choice well let's go with a green dot them okay I'm not I'm not trying to be the hypocrite the funny thing you're talking to most sound men won't use a limit okay we were emotionally against you mostly watch your dad but we are monitoring the machine that's another thing and often you have a chance to rehearse something so let's let's be safe and go with the green dot not if we're doing something we're able to monitor we can go without a limit sure the sound in the preceding minute and the succeeding minute which is the most valuable sound we can get is well recorded the sound during the actual running of the camera is rotten but it would be rotten anyway any sound that happens while the camera's running then yeah he uses the sound as what we call a guide track it tells him enough for him to try to recreate it well I'll tell you now you see that that's interesting maybe because that means that during this the real deploy sequence when we're really running that you don't actually use this any comments that the crew members make spontaneous about what you see and doesn't matter whether cameras running or yes even if we do we know what you what you felt if you look at that a while look at that isn't that incredible that's a really useful piece of so again you know some people will be sometimes picking those things up so again a mic in front a mic either in the middle in the after on this side I don't know I'm asking you well once again it's it's a simple case of having the microphone nearest the most activity but we don't have them so we don't have microphones everywhere front and back is obviously that's we just looked at as the most likely to get something of everything if there's no activity no one operating anything up front then I would move the mics back into this area and maybe an odd case where you want to make downstairs and went upstairs I'm not sure I guess yeah yeah once again down here in this part of the studio this is made for sound it is yeah it is I sort of wanted to finish up by just making you sort of going over a list we've always touched on many of them of things that you might want to record or or things to consider anyways just to repeat myself of course we're interested in trying to record anytime the camera is used a camera event and trying to record time before and after that event you know so I would sort of have the sound just roll minutes in advance of it and let it go for a while afterwards as a corollary to that if something happened during the camera event that you could could reproduce later that'd be great too but that's something that's really occupy your mind and I'm sorry a key line of the hell log or something somebody said but then secondly the thing to be aware of is to gather interesting sound which will be useful for this type of picture especially the comments are very interested in your in the crew's reactions to being here and things they see since this film is focusing on a lot of things that are out the window you know things that we're seeing on earth that if there were times where there was conversation about that maybe sitting in a meal while you were discussing what you saw in the previous few hours you know
