Finally I learned how to do camera tracking with Blender, now seems very easy, this is the best tutorial I ever found to learn how to use camera tracking, thanks!!!!
Lovely tutorial! Thank you so much! It is nice how you just show the whole thing and not skipping over little details or problems you run into along the way.
This is really a great and didactically well-done tutorial. I added this to my module briefing for my students. You forgot the camera lens distortion workflow. The tracker can solve the camera lens distortion and in your compositing, the "Undistortion" node will use the calculated data. You just need to add the node again at the end of the compositing tree and set it to "distort". This will distort the composed result back to the original plate and adds this distortion to your rendered layers.
Thank you Nick!! We will always learn something new from you! I'm putting this in practice looking forward to have a nice output or try until I get it right.
Hi! great tutorial, one question: is it necessary to track a point from start to end? I mean, there could be some point that goes beyond the frame at half the video and you cannot track it anymore, does this pose a problem? Thanks in advanced!
great tutorial thank you. my footage has movement in it where by a person is walking forward, so i can only track a small section of the begining and the rest of the clip. there must be a way to track everything, i am new to blender so i am not sure yet, will find a way to fight it out thank you
I have 6 tracked markers, camera sensor and focal length is set, a solve error of 0.41 but "Setup Tracking Scene" is still greyed out. Ideas,..suggestions?
how can i do this vice versa?, i have a clip which is stop motion animated action figure with a green screen. How do i create a 3d environment in blender to sync it with the animated character clip?
Thank you, I will reference this video whenever I do a project that needs motion tracking! By the way, does this work if you are using video footage to generate motion tracking for a fully 3D environment? I'm guessing you can just skip the steps where you adjust the scene to the video, yeah?
Someone please help me , i am having a problem..😩 the problem ( i did the camera tracking then i put the 3d character or the monkey but when iam rendering it the monkey is getting tranparent , means the monkey is getting faded but not getting into the scene ...please somebody help 😔
Great video thanks! I created some 3D objects over a tracked video and would like to export only the 3D elements and their shadows to overlay into the clip in davinci. I can’t seem to export from blender without the video! I unticked render from the camera visibility but still it renders. If anyone has any ideas…. Thanks!!
And could you tell me how to do the same, but so that I can calmly turn the camera to any place and the object remains in its place. The video will be useless if I look at the object all the time with the camera, why do I need it, and if I need to turn around ... This is not professional.
Does it seem better to use a motion tracker that is more automatic and to bring that information into blender for use? After Effects seems much better at this than blender...you are getting 8 trackers and taking minutes for each and AE can get 100 trackers and it does it for you....thoughts?
Good tutorial! But I do have a question. What do I do if there is a real-life object (like, say, a lamp post) that casts a shadow on the spot where I want my CG object to be? If I were to model the lamp post and place it in my scene, it will cast a shadow on Susanne, which is great - but it will also cast a shadow on the shadow catcher, which I do not want, because the real-life lamp post was already casting a shadow on the real-life ground. This means that the composited result will have both the real-life shadow from the original footage AND the shadow from the shadow catcher in it. Is there a way to make it so that ONLY Susanne will cast a shadow on the shadow catcher, and not my modeled lamp post too? Thanks!
14:50 is there a way to get it to automatically know where to put the camera and what "scale" the scene is supposed to be? edit: camera "rotation" works i guess but what about scene scale? like how do i force it to know what the scene scale is?
Around 6:50 - When a track fails, and you "tweak" it to adjust scale (of the tracker itself, not the search area) -- since you have that tracker set to track scale, does manually scaling it mess up the tracked scale data? Like if you scale it up 2x there, does it record a jump of 2x scale there that could negatively affect the track?
for the solve only the location matters. rotation and scale of the trackers eill never be taken into account to calculate the result. hope this answers your question✌🏻
@@BlenderDaily Oooh wow! Thanks! Same for all the other settings too then, such as "Affine," huh? All this time I was thought I was choosing what kind of "camera data" the point best represents, like how to use it for the solve, but I guess it's just telling the point how best to track that position for its location? Man, thank you, you really helped make a few things "click" for me just now!
this vid is highly appreciated, anytime im lost i just follow this again. my only problem was the first time when using your example video file, it used up like 95% of my 16 gigs of ram to prefetch it all, and would eventually crash around 18:00 or so while following your tutorial. for now my workaround is just using shorter clips. is 16gbs ram just not enough anymore or is there a solution? thx
Excellent tutorial. Just completely baffeled by the fact that you screw up the scene scaling. Why? To me it seems the whole process also knows exactly the distance to the camera of all trackers. So why scale it up?! It seems to me you only need to set the floor and everything is fixed.
Hi, if you want to only render once, you can use Turbo Tools to cache any portion of the compositor to a lower resolution to speed up compositing. It also denoises the individual passes so you don't need to use a denoiser in the compositor for even faster performance. It even lets you composite animation in real time! 3dillusions.gumroad.com/l/turbo_tools
Dude thank you so much. Despite the tutorial being a bit outdated I still managed to get an amazing result. For anyone that is stuck at the composition part, you don't need the denoise node anymore because the default denoising works just as well.
Out of all tutorials I’ve watched on blender motion tracking, this one is the best. Very detailed explanation and can follow very well step by step. Thank you for the efforts. Cheers
4:27 You should never start at the start of a clip to motion track it, but at the middle tracking both forwards and backwards. This is true in most cases, as it leaves less room for a failed track
You could've used one Blender feature called "set Y axis", when you tried to fix the perspective, instead of manually rotating the objects. Also you don't need to manually scale things down. You can set the scale using two points in the motion tracking settings.
This was a great tutorial. Just starting out in Blender I find that I get lost on most tutorials because steps are skipped. This tutorial was easy to follow because every step was clearly explained. Great job !!
I need help. I can see my video background in rendered viewport mode, but when I export the image then I don't see the background video. I only see the mesh and a transparent background
Hi, everything was going fine but when I try my first test render, it renders the object (monkey) and the shadow but not my film footage. Does anyone know why?
Run into some issues tracking vertical footage? Here's the solution: ua-cam.com/video/sujpvXrxV3o/v-deo.html
My monkey disappeared when I added hdr any solution?
fat respecto. very good tutor
By far, the most relevant Motion Tracking tutorial for Blender! Thank you, it was much needed!
Very glad you think so! thanks!
I love how and 29 min turns into a all night video...
Finally I learned how to do camera tracking with Blender, now seems very easy, this is the best tutorial I ever found to learn how to use camera tracking, thanks!!!!
very happy to hear that, thanks!
Thanks a lot. Would love to watch a similar video on compositing architectural building with drone footage.
Truly the clearest tracking tutorial! Thank you so much!
thanks a lot Fadi!
@@BlenderDaily gonna try and do it now thanks for the content!
So useful! Thanks for the video, I'm just starting my VFX trip and this is gold for me 🥇

Thank you so much. I got a lot from this video. This was very useful and you explained it in a way I could understand.
excellent tutorial, a logical and simple process, thanks!
such a clean and helpful tutorial thank u ❤❤
Finally i got it, thanks a lot, greetings from Argentina !!
Keep up the truly amazing work my friend. 😇

Wonderful tutorial. I acheived just the effect I wanted. Thank you very much.
Da sött mer mal mit em Hochdruckräiniger drüber :) Näi Spass, super Video wi immer! Mach wiiter so Nik, merci für all dini Tutorials!
besser ned, suscht gönd alli tracking points verlore;)
@@BlenderDaily :D
just what I was searching, great!!!
Longer tutorial available but also the better !
super clear tutorial
Looking awesome thanks for the tutorial
Hi! great tutorial, one question: is it necessary to track a point from start to end? I mean, there could be some point that goes beyond the frame at half the video and you cannot track it anymore, does this pose a problem? Thanks in advanced!
no, this isn’t a problem. you just have to have at least 8 active trackers on each frame
18:35 Thats helping alot
Yes, really helpful. Thanks so much.)
Awesome. Thanks
This is just what I needed. Thank you so much!!
awesome! glad I could help!
great tutorial thank you. my footage has movement in it where by a person is walking forward, so i can only track a small section of the begining and the rest of the clip. there must be a way to track everything, i am new to blender so i am not sure yet, will find a way to fight it out thank you
Amazing! Thanks!
WOW, thank you!
Very good tutorial, Thx 👍
glad you think so!!
great tuto and well explained..!! :)
Really good tutorial thank you!
it's not working when I plug and HDRI... the Shadow disappear...I have a light in the scene .........any solution for that?
how to find the sensor width and pixel aspect focal length of cam?
Hey, in my final render i only see the Background image but Not the 3d Object. Why is it so?
I have a problem - there is no video on backround in render mode, how to fix it?
cant take my eyes off them bike xD
I have 6 tracked markers, camera sensor and focal length is set, a solve error of 0.41 but "Setup Tracking Scene" is still greyed out. Ideas,..suggestions?
18:30 i click transparent but no background shows
perfect brother keep it up
YOU RULE tHANK YOU 🥰🤘
How to fix an issue with the PREFETCH? It loads and is stuck at 129 Keyframes? The total key frame is 327 as I am using your vid. Blender ver 4.1.
Thank you!!🤠
does a shadow catcher bg work on top of an emission material obj?
how can i do this vice versa?, i have a clip which is stop motion animated action figure with a green screen. How do i create a 3d environment in blender to sync it with the animated character clip?
is he speeding up the time it takes for the trackers or is his PC really that fast?
Thank you, I will reference this video whenever I do a project that needs motion tracking! By the way, does this work if you are using video footage to generate motion tracking for a fully 3D environment? I'm guessing you can just skip the steps where you adjust the scene to the video, yeah?
Does the quality of your graphics card help improve tracking?
ayy tysm :)!!!
Anyone know what the sensor width is for an iphone 12 pro?
Someone please help me , i am having a problem..😩 the problem ( i did the camera tracking then i put the 3d character or the monkey but when iam rendering it the monkey is getting tranparent , means the monkey is getting faded but not getting into the scene ...please somebody help 😔
Thank you, Sir
Great video thanks! I created some 3D objects over a tracked video and would like to export only the 3D elements and their shadows to overlay into the clip in davinci. I can’t seem to export from blender without the video! I unticked render from the camera visibility but still it renders. If anyone has any ideas…. Thanks!!
I have a problem. When I try to overlay a car onto my footage, it either shows only the car or a blank screen. I have no idea why.
It may be late, but you have to set transparent background and combine the render layer with the video by using an "alpha over" node
At 15:30 I have a question, what do you do if you don’t have any trackers on the floor, do you just add more?
And could you tell me how to do the same, but so that I can calmly turn the camera to any place and the object remains in its place. The video will be useless if I look at the object all the time with the camera, why do I need it, and if I need to turn around ... This is not professional.
HELP ME!!!!!!
My prefetch isnt working
on all apart from the first track it dont work all the way
I have a question, why did you go from last frame to first why not just do it noramlly?
is possible have some marker that appear only in some photogram for example changing the framing?
Good
Does it seem better to use a motion tracker that is more automatic and to bring that information into blender for use? After Effects seems much better at this than blender...you are getting 8 trackers and taking minutes for each and AE can get 100 trackers and it does it for you....thoughts?
For example, if I change the object to an object that already has a rig, can it still be animated?
Good tutorial! But I do have a question.
What do I do if there is a real-life object (like, say, a lamp post) that casts a shadow on the spot where I want my CG object to be?

This means that the composited result will have both the real-life shadow from the original footage AND the shadow from the shadow catcher in it.
Is there a way to make it so that ONLY Susanne will cast a shadow on the shadow catcher, and not my modeled lamp post too? Thanks!
Select the lamp post and then, in the sidebar, go to Object Properties->Visibility->Ray Visibility->Shadow (check/uncheck).
14:50 is there a way to get it to automatically know where to put the camera and what "scale" the scene is supposed to be?
edit: camera "rotation" works i guess but what about scene scale? like how do i force it to know what the scene scale is?
Instead of tracking in blender track it in after effects and copy that data in blender with the help of ae2blend plugin
Bro! why it's taking soo much time to track a single motion?
How do i track phone footage whenever i put it into blender it comes in sideways and i cant rotate it?
rotate it in the video sequence editor, export it and the import this rotated clip into the motion tracker.
wow
Around 6:50 - When a track fails, and you "tweak" it to adjust scale (of the tracker itself, not the search area) -- since you have that tracker set to track scale, does manually scaling it mess up the tracked scale data?

Can you please make one playlist about vfx ?
I actually have one already. You can find it in the playlist tab on my channel:)
Hi! Any thoughts on using this to insert transparent glass like objects to footage? Trying to make my footage show through.
in the render settings under film, you have to enable transparency and glass transparency
@@BlenderDaily Thank you so much!
this vid is highly appreciated, anytime im lost i just follow this again. my only problem was the first time when using your example video file, it used up like 95% of my 16 gigs of ram to prefetch it all, and would eventually crash around 18:00 or so while following your tutorial.
for now my workaround is just using shorter clips. is 16gbs ram just not enough anymore or is there a solution?
thx
you could also convert the video into an image sequence first, which usually uses less ram
@@BlenderDaily thank you sooo much for a reply! :D im researching the image sequence solution now, i have heard of this before.
I've got 32 gigs of ram and it gets to 38% before crashing.
OMG. I'm feeling that it's 10000x complicated than c4d.
Taking ages to track. Any ideas.
Excellent tutorial. Just completely baffeled by the fact that you screw up the scene scaling. Why? To me it seems the whole process also knows exactly the distance to the camera of all trackers. So why scale it up?! It seems to me you only need to set the floor and everything is fixed.
there's gotta be an easier way to do create tracker points rather than manually creating 8+ tracker points.
Use after effects it tracks 3d camera the best . Ithink there is a blender addon to use after effects 3d camera track data.hope it helped you😊

nice to hear that, thanks!
Why have you not used auto detect feature? As a rough start?
help me with this error please, when i try to render animation it says this: "width not divisible by 2: 1651 928"
Your width (of 1651) cant be divided by two
I need help. I can see my video background in rendered viewport mode, but when I export the image then I don't see the background video. I only see the mesh and a transparent background

Thanks for this very helpful tutorial and happy blending with blender.
Hi, everything was going fine but when I try my first test render, it renders the object (monkey) and the shadow but not my film footage. Does anyone know why?
Would it be possible if you share a video of my motion tracking example that you can tell me what I'm doing wrong?
it was worthy my 30min watching this tutoria,thank you so much.
