moving timelapse technical question!



Frage von saob:
Juni 2010

Hello everybody,
Most of you will now be moved lapse recordings like these: http://vimeo.com/11673745 know time. I know that this one Dolly was used, a camera was instaliert out and then all of a control unit is moved on the dolly.
My question:
Does anyone have any idea how to build itself can control this?

My idea: a elektormotor handles every X seconds to a string and then the camera draws ever closer on the dolly.
My problem is that I have no idea how I bring the engine to this, only every X seconds to turn a piece of next?

maybe someone has an idea:)

greet boas



Antwort von B.DeKid:

The shown video of you is more likely arisen without Dolly ;-)

The movements are more likely to come 100% from the PC.


For a motor code have to use DU CNC control boards and then you can use the program very simple.

Antwort von srone:

dear billy dkid
here you are mistaken, because the foreground in relation to the background and moves the filmer (photographer) mentions a motordolly, I am assuming that the it had been.

in terms of control of the dolly, I see the problem is closer to the shutter of the camera, which of you linked film is the situation day outside with relatively much light, so that set a relatively short shutter can, in this case is not at all the necessity, the dolly to bring stand for, which, in the period of tripping, max moved a few mm, in connection with the set ww and a short shutter synonymous photographed not so much different from the hand (and normal shaking), any slight motion blur, one would have video movies at the time anyway, so that such material is easily usable via timelapse.

Antwort von jwd96:

It goes very well with no synonymous Dolly, see:



Antwort von srone:

the tutorial shows, however, synonymous only a total situation without broached settings, like small mountains or the wire fence in the foreground of the linked videos, the tutorial to be transferred to the linked film, which would certainly be feasible set, but a significantly larger bearbeitsaufwand ahead.

Antwort von B.DeKid:

Ah ok sorry I had not read that with the Dolly / had seen.

Stay interfaces but this is the one with ner (step controller card), the scripting can be very simple.

Basically, can the LEGO NXT and tinker with it even on large engines transferred ;-))

Whether moving dolly or virtual camera movement, on the contrary really almost ne motive ask.

I like to think, and I am of the opinion that it is not necessary for the above motive, continuous motion goes as smoothly.

Antwort von B.DeKid:

You focus now on his sample video?

Yes of course you then right. I now had more cases of Timescape org in the head so night sky stars and so just kidding, where there will be quite long controlled bulp shots.

But basically this is irrelevant anyway because, you should work with Motioncontrolled Dolly and gain in the Virtual Effects before or this will entail a lot of possibilities.

I perso. 'm very hot on NEN MotionControlled system s.besten with me would allow the crane in combination with 3D programs, some of which goes like this just do not really clean.

motorized (r) dolly, crane arm (5-8m) and digital camera, memory-and editable rides (a la premiere keyframe-Beziers), that would be a dream.

Something like this http://forum.slashcam.de/realisierung-keinohrhasen-kamerafahrt-vt63881.html

The first answer is so what I want synonymous ;-))

Here's the demo video to ;-)) http://www.mocoforum.com/videos/cyclops.mpg

Ingenious Toy!

could look very good, I think we have so much fun. ;-)

Antwort von saob:

Hey B. DeKid
these cards, just s.einen CNC control circuitry to send electricity pole every X seconds, then I can hang s.den NEN engine?
do you think something like that he kind?: http://shop.strato.de/epages/61125483.sf/de_DE/?ObjectPath=/Shops/61125483/Products/SM22PCV3

to let the engine run just slowly I think this is synonymous possible. However, the inclusion period then very limited and if you want to record at night as the stars, you can forget ever with the engine running.



Antwort von B.DeKid:

If I say screw on my PC and now time gaze as the map.

My 3 outputs the three engines of the CNC has to raise bank.

The motors can be individually and then of course address synonymous thus increase the speed or lower.

So I thought das.

Then you need a sentence or even synonymous gears, pulleys and etc.

Then you have the script yes Directions speeds (acceleration curves) and etc to teach

My Glidetrack thread for the poor already know her intended, right?

http://forum.slashcam.de/glide-track-mini-dolly-fur-arme-vt81392.html

If I've eaten the same time I look at how the map is called ok.

MfG
B. DeKid

EDIT on the map is nothing on it I have time tomorrow to call my friend of the thing has cobbled together who knows with MaschinenSteurung.

Perhaps trunk of FXSUPPORT say what had tinkered on his old blog once NEN horny Slider had unfortunately is no longer new on the blog so far.



Antwort von saob:

cool, thanks!
yes I read the tread synonymous with interest:)
of the technical view there is not synonymous wonder, just the electronics makes me trouble.
for what you've got the three motors? rich, not a dead-on to the wrap or stuerst acuh you have the tripod (that swivel motors with the tripod). this card must be connected so s.nen pc. just a bit stressful in nature but not other's well?

beautiful evening!



Antwort von B.DeKid:

CNC for my bank I ne have so little things to tinker around so that different - I had once bought me was to create templates for ages but then the father of a friend because the card so a port was broken.

Now the thing is here again.

The one I know can drive motors of LEGO NXT

un which the bank can be controlled CNC synonymous fine I know from AutoCad as I have to give me time friend of NEM and Ner architect can in order to craft a few things.

Nen Dolly correct me I unfortunately can not yet build can not regulate everything, just everything lately become very stressful.

But imagining I can see it just as well and not be so synonymous the problem - who NEN Bissel paying attention in physics and technology should help with the NEN of some experts have tinkered good ...

You have really only ne control for the track A> B with write acceleration curve, then 2 Steurung for the head and a Steurung for the Camera menu, so bzgl shots.

This should be done for little money, expensive home here should only be Ansteurungs Map / unit and the motors.

Find missing part just exciting stuff. I would like that just like with 3D progi combine cameras so very precise movements to be transferred to this and then 3D landscapes / scenes with actual footage combine. That would be for me properly so the real goal.

MfG
B. DeKid
