Combine Object and Camera Tracking in Blender [Intermediate] | English

In this tutorial, I show you how to combine object and camera tracking in Blender to make a CG object interact with both a tracked object as well as the "world".

enable "normalize" in the tracking tab and your tracking will be even better!

[@JonathanKron]

Oh, thank you for telling me :D

[@gibsonjavier8271]

You prolly dont care but does any of you know of a way to log back into an instagram account? I was dumb lost the password. I would love any assistance you can offer me.

@Gibson Javier Instablaster :)

[@gibsonjavier8271]

@Dustin Charles i really appreciate your reply. I got to the site on google and im trying it out atm. Looks like it's gonna take quite some time so I will get back to you later with my results.

[@gibsonjavier8271]

@Dustin Charles it worked and I now got access to my account again. Im so happy! Thank you so much you saved my ass !

[@BlenderRookie]

Camera tracking can be fun but when it get frustrating it can become a headache. It's one of those things I'd like to get better at. Good tut.

[@stormgaming7379]

Just a tip for some people: Using the "Affine" tracking solution instead of perspective or location is much better for tracking soft objects (such as clothing, faces, hands...etc). It is more processor intensive, but it'll give a much better tracking solution for those examples

[@SashaBon]

Perfect tutorial! Thank you!

[@OfficiallyOToole]

This is literally what I'm just getting into!

[@EmpireAnimator]

Thanks man it Helped a lot 🎉❤

[@patricklevar]

This was great 👌 thank you 🙏🏿

[@aim__freakz8499]

Really good video! :)

[@x-TheTheo]

Amazing! Subbed, and liked.

[@pianoatthirty]

Thank you for this!!!

[@basejumperdx4573]

awesome bro make more live cg. photrealistic live cg this is something most people not doing with blender but cycles is awesome

[@firefoxbrowseraccount5709]

Cool man

[@EdNorty]

Wow, I gotta remember to click "scale" hehe

[@ukmonk]

thank you! any chance of doing a tutorial on holding a CG prop for eg, like a sword or gun, i cant figure out how to set this up in blender :)

[@JonathanKron]

It's definitely on my bucket list. But I still have some figuring out to do :D

[@ukmonk]

@@JonathanKron thanks Johnathan, I love blender but somehow never get the tracking to work for me. I always go back to after effects. In blender can I just manual track a couple points if wanted please? I don’t mind manual tracking if it will work.

[@JonathanKron]

@@ukmonk You can always use manual tracking. But tracking at least 8 points through your entire scene is pretty hard. There are ways to export AE Camera tracking data to Blender. Haven't tested this but I saw someone do it. Maybe try searching for it and see if there are any tutorials :D

[@ukmonk]

@@JonathanKron thanks so much for replying Jonathan and merry christmas :)

[@1qu4rto20]

how do we remove the X's in the video to make it real?

[@mcpaddock_de]

thank you !

[@fangdada]

How do you mark the points clearly

[@johnshepherdsg]

Can you use object tracking to animate a armature rig?

[@JonathanKron]

You can probably parent the bones to the tracking points (you can create meshes from the point as shown here: kzbin.info/www/bejne/iZPOiZVpZqmliKM)

[@JustCurious-ou6gn]

What if the position of the tracker points are way lower in the viewport/layout? They are far apart. How can I move it to the exact position? which is to see in the motion tracking. I have trackers 8 with a solve error of 11.35 px. how can I change it under 0.5 px? I just cannot find the answer anywhere

[@fangdada]

you can open the plugin: refine tracking solution，It can help you solve problems

[@MurderousLamb]

I'm running into an issue. When I hit render, the object that I made doesn't appear in the render. I have everything enabled.

[@JonathanKron]

Is it in the correct (Foreground) collection? If so then I probably can't help you and you should ask your question on the Blender subreddit or forums (which allow you to add images, etc.)

[@user-wz7nq9pf5y]

8:18 What is this problem? More information, please.❤

[@DadicekCz]

I've made plenty of Blender psysics simulations in my life but when i try psysics in a camera tracked scene, literally nothing happens. Always. All setup is the same as in other scenes but when there's a tracked camera, simulations don't work for me :/ I would appreciate any help

[@JonathanKron]

Hi, what often messes it up for me is the scale. Blender tends to work better in large scale scenes. You can also have a look at the rigid body scene settings. Maybe it's disabled?

[@eminencegrise3787]

I had that once. I copied the cell fractured object and placed it in a new camera tracked blender scene. It worked out then, even though it is not really a fix.

[@flipnap2112]

I would think the one constant is blender units. probably need to scale the tracking and all objects much larger or smaller. the tracking is all relativel to the camera, so it doesnt matter how much you scale the cam/tracking. but it will change the sim behavior.

[@bhargavpatel_]

how to remove that tracking markers

[@JonathanKron]

There is a great tutorial from CGMatter on how to do so: kzbin.info/www/bejne/jn20lKSLfM2ji7s

[@wellinspired4657]

What if we don't have those tracking points drawn in?

[@JonathanKron]

Then you'll need to track different, high contrast areas in your shot. If you filmed somewhere with lots of different textures this shouldn't be a huge issue.

[@wellinspired4657]

@@JonathanKron Gotcha, im tracking a friends hand rn so i could place a pokeball in his hand. For some reason it won't track the whole clip, i have to be lucky by pressing ctrl T everytime. First time using blender.

[@flipnap2112]

learn how to paint out trackers if you can.. or learn how to do supervised tracking. best to shoot with a high frame rate and not use digital stabilization in camera. it will still record the blur. use optical stabilizers. you can add 2d motion blur in post. tracking has its own pre production considerations

[@lazycreator7794]

Woowwwwwwwwww

[@mambaman2007]

I'm wondering does blender 2.9 still need lens information to match and track?

[@JonathanKron]

I think tracking hasn't changed much, it has become a lot faster though.

[@user-zd7cq8xq7y]

hi bro can you make a video now of a headtrack by geotracker and also combining it with groud tracking like i want to put something on head of a character and also something behind on floor
