3D motion tracking in Blender and Voodoo Tutorial *FREE*[Part 2 of 2]

[MRLosaren]

How do i upload a blender movie to youtube? :P

[BlenderBug]

for those having trouble running the script--->you have to make sure to save the blender script as a 2.4x file type first.(in the save menu in Voodoo)

[HomebeatRecords]

THANK YOU, IT WAS HELPFULL

[rotandroll666]

thanks for the tuts! you great

[Friendspoint123]

Whenever I run the script, an error shows up which says console error and the string "Import mathutils" gets highlighted. What do I do to solve this? Please help...

[dummerbube]

So the latter part that you explain is about just rendering out the objekt itself moving in "space" - and this new rendered track can be put in another track in the video editor, right?

Because the problem that I see isn't black bars (which indeed is a problem), but that with each rendereing the video quality decreases. So I'd prefer just to render out the object and insert that into the video that gets edited in the NLE.... Ohh... I guess I could need your help...

[KHdarkRoxas]

IN BLENDER

---------->2.57 please

[gearykid]

Only problem is... the object has no shadow... other than that, great job!

[Hyroyan98]

NONE OF THESE TUTORIALS ARE FOR 2.5!!!!!

[camii71]

how do you add shadows in the render

[waj171]

Cam studio FTW!!!

[kurentmalik]

What am I doing WRONG!? When I run phython script, and I go back to my 3D view, and blender doesnt show dots!!! What the hell! All I get is another camera and a null object parented to this new camera. Crazy.

[DeathstarDude123]

@kurentmalik the same happens with me

[tutorialzit]

Thanks for the Tutorial! :)

[hjalteyhjalte55555]

it did not work. i could not run the script

[RyTrombs]

are there any specific softwares you need to run blender and voodoo?

[airsoftreviewers09]

This was so helpful thanks a lot!

[k3n0bl]

Awesome Video, problem is blender changed almost everything from all the youtube video tutorials. I managed to load the python script finally despite numerous errors.... now I can't even get the background video behind it because i don't see it on the list from VIEW->BG IMAGE... doesnt exist

[jordannw2010]

8:12 when you say hit f12 to render does that mean i have to wait till it finishes the render before moving on?

[TheDuckCow]

…… if you've got after effects, I would hope you aren't actually using VooDoo.

just a thought ;)

[hagen552]

would this be possible with a chroma keyed video instead of a 3d object?

[casvlaco]

when i try it, the dots and other objects dissepear at frame 32, what do i have to do?

please answer

sorry for myy bad english, im dutch

[jordannw2010]

@casvlaco it isnt bad english, dissepear is spelt disappear, but thats fine apart from that. :D

[petcarlson]

Hey i love the tutorial. Just one tip for you...when u rotated the cube u could just press r 2 times and you get a free rotate feature.

[d3sertst0rm]

haha what happened there at 7:50 :D

[awesomepeople9428]

Guys!!! If it tells you there was a python error thingumajig and it won't let you use the footage, download an older version of Voodoo Tracker!!! I downloaded version 9 because I think this is the one he is using! Thumbs up if this helped you so others can be helped too!

[haleva93]

thank u so mush !!

a great tutorial

[awesomepeople9428]

it keeps saying that there was a python error, please help!

[chivasxvida]

ive used blender for simple stuff for clients, your good but u dont really have an idea of what most of the stuff is lol but i guess if it helps ppl its fine.

[DerpyAdventures]

Text;

Run Python Scrypt;

It tells me "Python scrypt error: check console"

Does anyone else have this problem?

[panther2552]

awesome tutorial bro. thanks a ton for this.

[epicawesomesauceguy]

Omg im getting really mad now i go to the camera view and the thing dissapears and rjiwejafioafjiasop[

[rdinhothenry]

Here's the fix for Python in 2.5:

Save as Blender Python script. Then open that file in Microsoft Word. Press Ctrl+f. That should open a little box that has three tabs across the top. Click replace. In the find what section type "set_frame" without the quotations. In the replace with type 'frame_set" without the quotation marks again. Then click Replace All at the bottom. The number of replacements it makes should match the number of frames in the scene. Then copy and paste into Blender.

[blablabla45971]

@rdinhothenry doesn´t work

[Mythbusters5436]

O.M.G Stop Saying UM!!! XD

[LegoVideoPerson3000]

Help when i click run python script it said error HURRY MAN PLAESE

[victorkafanov]

I try tracker! I anim and blender crashing! PLEASE HELP ME! I have a big problem!

[brogliman]

when i try to do the last step from your Part: 1 video, I get a error that says "Python script error: check console" some other people left similar comments on that video. I've downloaded multiple versions of python multiple times and restarted my comp multiple times as well. Does anyone know why?

[gkclan]

@brogliman when you are save the tracking data into blender python script remember set the files of type is Blender 2.4x or lower ( in case you are using blender 2.49b or lower ) if 2.5x or higher choose Blender 2.5x or higher it will work as it should :) thumb up for everyone can see !

[abePdIta]

Thanks! :)

[rboetsma1]

im using blender 2.5 beta but when i try to run the python script an error message comes up and wont let me run it

[CGRednaz]

thanks alot, cant wait to try it out xD

[PADprolo]

how do you add a clip onto the tracked footage rather than a 3d object? for example a clip of an explosion rather than the 3d cube?

[goeiecool9999]

i'm so happy my cam films without black bars that realy saves my a lot of time

[EpicCookie7]

i have a problem: those dots go perfectly about a second and the they just freeze. how to fix this? also i noticed that when voodoo is tracking. the lower process bar stays in 19%.

please reply :7 it would be so cool if i could get this working :(

[RunningLemonStudios]

Cool cool. Nice tutorial.

[EzzieNet]

When I get to the part at 5:04 instead of having the video there, i have the cube and not the video.

[sodium44]

my background vid woont show up :S

[exelto111]

@sodium44 same thing with mine... :(

[pwnage2own]

@sodium44 If your background vid won't show up, then you need to download VirtualDub, open your avi in it and then save your avi as segmented avi then it should open up (assuming you got an avi file). For Blender 2.57, you can fix your python script here if it's giving you errors:

ht tp :/ /st atic. wikeo. be/f ile s/15 209/vo ofoo fixer .sw f

^ Remove all spaces to get link

(for above link) Clear the top box, paste your script in there, press fix. Then select all and copy it back to Blender.

[sodium44]

should i download the windows binary file or the windows installer version??

[woodsy1234567890]

if i want to do bullet time

can i use key frames to move my bullet and render it with the video?

[336pokemon]

1 person told me that to make a pokemon batle you need after effects but then you teel me that is tis program dude this gives me de creeps

[lastsiteliving]

Great Tutorial!

I will try this as soon as i can.

[TheMeRockURock2]

how do you start off? do you just press encord



[DoubleR666]

great tutorial !! thank you a lot it helps me a great deal !!

Thanks Thanks Thanks !!

[swetrich]

thanks man! im decent at blender but im waay better at video editing, but now im gonna combine the skills

is that a legal download of voodoo?

[robertcochransvideos]

dude at 2:53 when you move zoom around, how do you keep it from focusing on the middle. like the red and green lines that meet up at a cross. I want to roam around the intire shot but it wont let me. please respond. its driving me crazy.

[la12muerta]

fuck dude seriously why are you not responding, people need your help and you need to reply =o

[csavoy1]

I tried this and the camera works well at first then it goes wild and just points up. What happened?

[2BAPokemonMaster]

theres a question like this down below. This can be caused by a jerky camera motion or just a low contrast shot. These are the only things i know of that would make the camera do that.

[TheFXGuy]

@2BAPokemonMaster Or just because voodoo sucks...  I've only had it work once, and that was with a shot that panned at a constant speed. Other than that, it got 1-2 frames before going crazy on every shot I've ever tried.

[AleF1231991]

Thanks for the tutorial. Can I use Voodoo and Blender to create a 3D model of an object? (Sorry for the english, I'm Italian..)

[M0rganstudios]

Again, great tutorial man :)

[b94kw]

It worked well the first 2 seconds, but then the camera looked away from the dots and frose. I did excactly as you showed, and ive tried many times but it wont work. Ive even tried it on 2 different computers and with 2 different cameras!

Please help me!!!

[Dayantos]

Happened to me too. In my case it was caused by too fast camera movement, try to keep far away from what you are filming, and move slovly and it will likely be better.

Also, what I did was that I had a clip where I moved too fast before the 3D was supposed to come into the view, so I just cut it away and I'll paste it back together later. Movie maker does change the framerate (destroys quality), but I couldn't find any alternative other than refilming.

[maga2811]

Thank you very much, it really helped me

[xXRequiremXx]

show the final video!

[multimediahelp1]

people with a mac and blender can use icarus.

[xXRequiremXx]

what is icarus?

[unetunfontdeux]

decent description of how to do this, but um I um think you.... think you um, need to um stop saying um when um you um are making um a video um like.... like this. um. It's really distracting when the person in the video isn't clear and concise. But like I said, decent video.

[JANTSUU]

Thanks a lot! Very helpful.

[rhymetactics]

So great dude! I will be using this for sure!

[KireEsuark]

Hey this video was awesome, thanks so much. I dont know if you were planning to but if you are going to make more tutorials i would really love to see one about green screening with an actor using motion tracking and voodoo/blender to create a 3d environment, so you can have a digitaly rendered environment that will respond to camera movements and angle changes. That would be great because i cant find anywhere how to do it.

[Oatinator]

Five stars for you! Thanks a bunch!

[yesturtle]

this is really good man, thanks.

[jhwblender]

Do you know how to put shadows under the object using a plane, I am having trouble with that, thank you for any support.

[avelx]

You will need to watch a video tutorial on compositing. just type in youtube blender composite tutorial. That should solve it!

[fgbfgfgbgbf]

@jhwblender at the shader options, next to where you set the specular, you have a button called "OnlySha" (only shadow)

if you also change the ambient color setting, you should get either a harder or a softer shadow

[jhwblender]

Oh Ok, thank you, I figured it out :-)

[dtr0005]

Quick question.... How would one go about adding a live action element as an overlay on a background plate? An old-school filmaker

[PureT3x4n]

um. nice tutorial.

[barfsonyou99]

Can this be used in 3D Studio Max?

[RandomNationSeries]

Yes... in voodoo export as a max file.. not blender.... hope this helps..

[pithikoulis]

7:50 LOL :D

[bluescreenjames]

LOLAGE AT 7:50

[bloodjake12]

Whats so funny???

[2BAPokemonMaster]

LOL i guess i forgot to cut that out, i did that so i knew were my mistakes were so i could cut them out.

[BASEBALL1943]

I followed the instructions and I have no dot's in 3d mode?

[GlitchMasterSonic]

When I exported it to blender, the blender camera goes in completely random parterns and directions. Does anyone have sugestions?

[SpecialFxKid]

same thing happened to me. i tried a different shot. I also exported all of the points when i saved it in voodoo

[SpecialFxKid]

thank you. very helpful.

[TheAmazingJimmy]

Another way to get rid of the "black bars" is to interlace the video, or if you want your render to look like it has more of that "real video" effect, simply click the even and odd field rendering, you will get even and odd fields, aka "black bars".

[alfonso777]

How do i convert avi files to tga secuence? cuz my video camera captures in avi format.

[Jazza159]

it says at the start of part 1, you do it in blender

[blazer003]

That's the initial work in Blender in part 1.

[billamu]

Excellent tutorial. Thank you!

[2BAPokemonMaster]

Thanks you for everyone that has watched this video, commented, and subscribed. It really means a lot to me!

[0gnaws0]

EXCELLENT!!  Very informative.

Wondering how you could get and object, in this instance the cube, to cast a shadow?

Thank you for putting this together.

[ubuntuuser06]

To keep it simple: You can add a plane to the scene, place it under the cube, go to material buttons, add a material to the plane and activate "OnlyShadow" in the Shader panel. This will tell Blender to only render the shadow that objects will cast over it.

If you have more complex scenes and objects you may have to make use of more Options as or different techniques, but that's the way I did it yet and it worked good.

[0gnaws0]

Right on!  Thank you, ubuntuuser06.

[jeremiahjw]

Wow, the idea of using the 3D points to position the objects is BRILLIANT! This is soooo helpful!

[NonProfitProd]

Great Tutorial, just a little to much "Aaaam", what disturbed. But doesnt matter, the things you showed and said are very great and will help a lot! I think, you will get A LOT of Hits. Thank you, and have Fun. Bye from Germany, Munich. :-)
