▶ 13 - What is MRMC's Target Tracking and how to use it — Watch on YouTube

okay so I'm now going to explain okay so I'm now going to explain something about uh what we call Target something about uh what we call Target something about uh what we call Target tracking Target tracking was developed tracking Target tracking was developed tracking Target tracking was developed by Mar Roberts motion control um over 30 by Mar Roberts motion control um over 30 by Mar Roberts motion control um over 30 years ago and it was unique at the time years ago and it was unique at the time years ago and it was unique at the time in terms of it allowed you to create in terms of it allowed you to create in terms of it allowed you to create moves that were otherwise incredibly moves that were otherwise incredibly moves that were otherwise incredibly difficult to achieve accurately without difficult to achieve accurately without difficult to achieve accurately without using lots and lots and lots of key key using lots and lots and lots of key key using lots and lots and lots of key key frames which then made the moves rather frames which then made the moves rather frames which then made the moves rather wobbly if you did that so what it wobbly if you did that so what it wobbly if you did that so what it involved is you're basically creating involved is you're basically creating involved is you're basically creating key frames um there are the camera key frames um there are the camera key frames um there are the camera position and the target position and the position and the target position and the position and the target position and the software will work out what to do in software will work out what to do in software will work out what to do in between assuming that the camera has a between assuming that the camera has a between assuming that the camera has a path and the target has a path obviously path and the target has a path obviously path and the target has a path obviously nowadays in 3D uh uh programs and CGI nowadays in 3D uh uh programs and CGI nowadays in 3D uh uh programs and CGI programs you generally have a camera programs you generally have a camera programs you generally have a camera path and a Target path but in terms of path and a Target path but in terms of path and a Target path but in terms of motion control that was quite unique and motion control that was quite unique and motion control that was quite unique and I'm going to show you how that's used so I'm going to show you how that's used so I'm going to show you how that's used so let's say I'm going to create a move and let's say I'm going to create a move and let's say I'm going to create a move and this time I'm going to not use any this time I'm going to not use any this time I'm going to not use any Targets so I'm going to turn on my free Targets so I'm going to turn on my free Targets so I'm going to turn on my free drive and I'm going to start let's say drive and I'm going to start let's say drive and I'm going to start let's say let's say actually I'm going to go down let's say actually I'm going to go down let's say actually I'm going to go down a bit let's say this is a bit let's say this is a bit let's say this is my first position like that my first position like that my first position like that there you go so I'm going to store there you go so I'm going to store there you go so I'm going to store this uh this uh this uh store and add a key frame and now I'm store and add a key frame and now I'm store and add a key frame and now I'm going to do another here here okay St that and free Drive good so I have a simple and free Drive good so I have a simple two-point move if I look at it two-point move if I look at it two-point move if I look at it here that's what it looks like looks here that's what it looks like looks here that's what it looks like looks okay doesn't look like there's anything okay doesn't look like there's anything okay doesn't look like there's anything wrong with wrong with wrong with that but actually let's run it so going that but actually let's run it so going that but actually let's run it so going to turn run it to turn run it to turn run it forwards okay it's complaining about my forwards okay it's complaining about my forwards okay it's complaining about my truck I'm not using my track at the truck I'm not using my track at the truck I'm not using my track at the moment so I'm not too concerned but I'm moment so I'm not too concerned but I'm moment so I'm not too concerned but I'm just going to turn it on so it doesn't just going to turn it on so it doesn't just going to turn it on so it doesn't keep complaining about it I'm at the end keep complaining about it I'm at the end keep complaining about it I'm at the end so I'm going to run it so I'm going to run it so I'm going to run it backwards okay does a little goto and backwards okay does a little goto and backwards okay does a little goto and then shoot so that's my move now if we look shoot so that's my move now if we look at the at the at the camera uh forward run camera uh forward run camera uh forward run shoot other than the fact it's out of shoot other than the fact it's out of shoot other than the fact it's out of focus uh it's kind of drifting off off focus uh it's kind of drifting off off focus uh it's kind of drifting off off it as well um let me actually try and it as well um let me actually try and it as well um let me actually try and make that more make that more make that more obvious uh so I'm going to adjust my obvious uh so I'm going to adjust my obvious uh so I'm going to adjust my move even further move even further move even further uh let's go put into free uh let's go put into free uh let's go put into free drive okay just going to turn on my okay just going to turn on my tilter and adjust my tilter and adjust my tilter and adjust my focus okay and now let's store this as my new last now let's store this as my new last frame stor and then run it frame stor and then run it frame stor and then run it backwards backwards backwards okay and okay and okay and shoot now you can see that it drifts off shoot now you can see that it drifts off shoot now you can see that it drifts off the can quite badly let me just adjust the can quite badly let me just adjust the can quite badly let me just adjust my focus so it becomes my focus so it becomes my focus so it becomes clearer again just going to use my tilter just to my tilter just to store my key frame at this point store store my key frame at this point store store my key frame at this point store my first key frame and then go forward my first key frame and then go forward my first key frame and then go forward run run run shoot it drifts way off my can okay shoot it drifts way off my can okay shoot it drifts way off my can okay now now now uh the reason for that is because it uh the reason for that is because it uh the reason for that is because it doesn't know where my target is and each doesn't know where my target is and each doesn't know where my target is and each axis of the rig is moving independently axis of the rig is moving independently axis of the rig is moving independently okay so what I actually need to do okay so what I actually need to do okay so what I actually need to do is tell it where my target is so it is tell it where my target is so it is tell it where my target is so it keeps looking at it now this unit has a keeps looking at it now this unit has a keeps looking at it now this unit has a focus assist but I'm going to pretend it focus assist but I'm going to pretend it focus assist but I'm going to pretend it doesn't and the way this is doesn't and the way this is doesn't and the way this is traditionally done is by measuring the traditionally done is by measuring the traditionally done is by measuring the target so I'm going to measure from my target so I'm going to measure from my target so I'm going to measure from my measure point which at the moment is set measure point which at the moment is set measure point which at the moment is set to be the film plane it doesn't have to to be the film plane it doesn't have to to be the film plane it doesn't have to be but it's on on here it's set to be be but it's on on here it's set to be be but it's on on here it's set to be the film plane and I'm going to measure the film plane and I'm going to measure the film plane and I'm going to measure to my to my to my target okay and and that is 54 target okay and and that is 54 target okay and and that is 54 cm okay so what I do uh I'm at the end cm okay so what I do uh I'm at the end cm okay so what I do uh I'm at the end of my move so I'm going to type here of my move so I'm going to type here of my move so I'm going to type here there's a line here called Target I'm there's a line here called Target I'm there's a line here called Target I'm going to type in 54 going to type in 54 going to type in 54 cm okay cm okay cm okay similarly uh if I was in my other wayo similarly uh if I was in my other wayo similarly uh if I was in my other wayo display which is Some people display which is Some people display which is Some people prefer horizontal okay my target it is prefer horizontal okay my target it is prefer horizontal okay my target it is here so this is my 54 cm there and here so this is my 54 cm there and here so this is my 54 cm there and switch switch switch back okay now I'm going to do the same back okay now I'm going to do the same back okay now I'm going to do the same thing with my first thing with my first thing with my first point okay so there are various ways to point okay so there are various ways to point okay so there are various ways to get it there I'm just going to run it get it there I'm just going to run it get it there I'm just going to run it backwards backwards backwards okay shoot okay so I'm going to measure my shoot okay so I'm going to measure my target distance distance distance 106 so I'm going to type 106 so I'm going to type 106 so I'm going to type in in in 106 now some of you Keen eyed people may 106 now some of you Keen eyed people may 106 now some of you Keen eyed people may have seen that my focus didn't adjust to have seen that my focus didn't adjust to have seen that my focus didn't adjust to my focus uh earlier when I ran the move my focus uh earlier when I ran the move my focus uh earlier when I ran the move um and that's because I had left my um and that's because I had left my um and that's because I had left my tilter wireless control on so I'm going tilter wireless control on so I'm going tilter wireless control on so I'm going to turn it off so that flare has control to turn it off so that flare has control to turn it off so that flare has control of the focus otherwise Wise It's not of the focus otherwise Wise It's not of the focus otherwise Wise It's not happy okay good so what I do is I'm happy okay good so what I do is I'm happy okay good so what I do is I'm going to go to tracking up here and turn going to go to tracking up here and turn going to go to tracking up here and turn on target tracking now there are many on target tracking now there are many on target tracking now there are many modes of Target modes of Target modes of Target tracking really the main one that gets tracking really the main one that gets tracking really the main one that gets used is just normal Target tracking used is just normal Target tracking used is just normal Target tracking which is just on or sometimes camera which is just on or sometimes camera which is just on or sometimes camera orbital the others are used as well but orbital the others are used as well but orbital the others are used as well but really between those two it covers 99% really between those two it covers 99% really between those two it covers 99% of of of cases okay so I'm just going to turn it cases okay so I'm just going to turn it cases okay so I'm just going to turn it on on on and and and then uh the other thing I'm going to do then uh the other thing I'm going to do then uh the other thing I'm going to do which is quite useful is I'm going to which is quite useful is I'm going to which is quite useful is I'm going to say that my say that my say that my role will remain level just keeps role will remain level just keeps role will remain level just keeps everything level that means that it will everything level that means that it will everything level that means that it will keep the camera level as it moves uh if keep the camera level as it moves uh if keep the camera level as it moves uh if I want to have some adjustment I can put I want to have some adjustment I can put I want to have some adjustment I can put it into relative uh moves will basically it into relative uh moves will basically it into relative uh moves will basically leave it completely independent and um leave it completely independent and um leave it completely independent and um generally is uh not used on this type of generally is uh not used on this type of generally is uh not used on this type of machine it's either level or machine it's either level or machine it's either level or relative relative relative okay so now I'm going to run this okay so now I'm going to run this okay so now I'm going to run this forward forward forward run okay go run okay go run okay go to and then shoot and I don't know if you spotted shoot and I don't know if you spotted that but it basically kept the can in that but it basically kept the can in that but it basically kept the can in the the the center very different to center very different to center very different to this turn it this turn it this turn it off okay forward off okay forward off okay forward run it doesn't like the fact that my run it doesn't like the fact that my run it doesn't like the fact that my roll is set to relative which it can't roll is set to relative which it can't roll is set to relative which it can't do when it's not in Target tracking so do when it's not in Target tracking so do when it's not in Target tracking so I'm just going to turn it to moves and I'm just going to turn it to moves and I'm just going to turn it to moves and forward run and forward run and forward run and shoot it's drifting completely off the screen okay so there you see the huge screen okay so there you see the huge difference that Target tracking can make difference that Target tracking can make difference that Target tracking can make on that relative forward that relative forward run shoot um shoot um and here you'll see that it's joined and here you'll see that it's joined and here you'll see that it's joined everything up those two key frames with everything up those two key frames with everything up those two key frames with a straight line and these are my a straight line and these are my a straight line and these are my two target positions because each key two target positions because each key two target positions because each key frame or Waypoint has its own Target frame or Waypoint has its own Target frame or Waypoint has its own Target position it means that targets don't position it means that targets don't position it means that targets don't have to be stationary you can have have to be stationary you can have have to be stationary you can have moving targets you could be following moving targets you could be following moving targets you could be following the edge of a box or the line on a map the edge of a box or the line on a map the edge of a box or the line on a map uh or somebody who is moving from one uh or somebody who is moving from one uh or somebody who is moving from one position to another targets don't have position to another targets don't have position to another targets don't have to be stationary just as cameras don't to be stationary just as cameras don't to be stationary just as cameras don't have to be have to be have to be stationary if I want to add a middle key stationary if I want to add a middle key stationary if I want to add a middle key frame now it's very simple now that I've frame now it's very simple now that I've frame now it's very simple now that I've got those two key frames in got those two key frames in got those two key frames in it knows where my target it knows where my target it knows where my target is along that is along that is along that path so I can drag it to anywhere along path so I can drag it to anywhere along path so I can drag it to anywhere along that path and it already knows where my that path and it already knows where my that path and it already knows where my target is I don't actually have to target is I don't actually have to target is I don't actually have to remeasure it if it hasn't moved so I can remeasure it if it hasn't moved so I can remeasure it if it hasn't moved so I can easily for example go up around my up around my can horizontally let's go the other way closer and because it knows where my closer and because it knows where my target is it's automatically focusing as target is it's automatically focusing as target is it's automatically focusing as it does this you'll see in the Target it does this you'll see in the Target it does this you'll see in the Target column here that it's automatically column here that it's automatically column here that it's automatically focusing as I do this okay and I'm going focusing as I do this okay and I'm going focusing as I do this okay and I'm going to store this key frame as another new to store this key frame as another new to store this key frame as another new one it's not a key frame I haven't one it's not a key frame I haven't one it's not a key frame I haven't created a key frame yet I'm going to created a key frame yet I'm going to created a key frame yet I'm going to create now so add a new Waypoint way create now so add a new Waypoint way create now so add a new Waypoint way added and I'm going to store this as my added and I'm going to store this as my added and I'm going to store this as my new position it's automatically put it new position it's automatically put it new position it's automatically put it at frame 37 cuz that's where it thinks I at frame 37 cuz that's where it thinks I at frame 37 cuz that's where it thinks I am and I've now created the move and am and I've now created the move and am and I've now created the move and this is what it looks this is what it looks this is what it looks like okay now I'm I've put in quite a like okay now I'm I've put in quite a like okay now I'm I've put in quite a change and I'm running it relatively change and I'm running it relatively change and I'm running it relatively fast it's still only a 2C move and fast it's still only a 2C move and fast it's still only a 2C move and you'll see here this has turned red you'll see here this has turned red you'll see here this has turned red because it thinks there's a problem if I because it thinks there's a problem if I because it thinks there's a problem if I I either can press here or I can press I either can press here or I can press I either can press here or I can press forward forward forward run and it'll tell me there's a problem run and it'll tell me there's a problem run and it'll tell me there's a problem which is the same as just pressing here which is the same as just pressing here which is the same as just pressing here and it tells me that these two axes this and it tells me that these two axes this and it tells me that these two axes this one's going too fast both of them are one's going too fast both of them are one's going too fast both of them are over over over accelerating and this is effectively by accelerating and this is effectively by accelerating and this is effectively by this is 49% too fast or over this is 49% too fast or over this is 49% too fast or over acceleration this one's just a little acceleration this one's just a little acceleration this one's just a little bit over 3% over so I'm going to change bit over 3% over so I'm going to change bit over 3% over so I'm going to change this and just run it slow this and just run it slow this and just run it slow uh it can either I can either run it at uh it can either I can either run it at uh it can either I can either run it at 33 frames per second or I can increase 33 frames per second or I can increase 33 frames per second or I can increase it to 150 frames in total I'm going to it to 150 frames in total I'm going to it to 150 frames in total I'm going to change this manually to 25 frames per change this manually to 25 frames per change this manually to 25 frames per second okay and now it's green it's second okay and now it's green it's second okay and now it's green it's totally happy I'm going to run it so totally happy I'm going to run it so totally happy I'm going to run it so it's in the middle of my move so it it's in the middle of my move so it it's in the middle of my move so it doesn't matter which one I press it's doesn't matter which one I press it's doesn't matter which one I press it's going to have to do a go-to to get get going to have to do a go-to to get get going to have to do a go-to to get get there so forward run goes to the there so forward run goes to the there so forward run goes to the beginning shoot shoot okay so with regards to Target okay so with regards to Target okay so with regards to Target tracking you can always measure with a tracking you can always measure with a tracking you can always measure with a tape measure that always exists and most tape measure that always exists and most tape measure that always exists and most rigs rigs rigs the especially the larger ones they the especially the larger ones they the especially the larger ones they don't necessarily have a focus assist um don't necessarily have a focus assist um don't necessarily have a focus assist um but when you have a focus assist you can but when you have a focus assist you can but when you have a focus assist you can use that instead or you can focus use that instead or you can focus use that instead or you can focus manually and use that that manual focus manually and use that that manual focus manually and use that that manual focus as your target distance
