For people who recorded VERTICAL iPhone videos and are motion tracking in blender, and are having an issue where the ground seems to be "floating" and any objects placed keep moving around without staying still here's a solution:
Click on the camera, go to camera Data settings -> Under 'Camera' and 'Sensor Fit', change the Sensor Fit to HORIZONTAL. This will make the ground plane stay in place for vertical videos.
bro it didnt work. still the objct moves with cam. plz help,
One of, if not the best and straightforward, explanations of tracking in Blender I've seen. Excellent tutorial.
You deserve a follow. Strong teacher's genes, very structured knowledge and a great voice. Thank you for your contribution.
the best tutorial for motion tracking in blender! thanks!!
This is such a fantastic tutorial! Thank you. Learning this has always gone over my head and you have simplified things elegantly easy to follow. Many thanks
thaaank you so much for this great educational video
this is one of the most useful tutorials about camera tracking in blender
thank you
Why thank you
Nice tutorial. Very informative 👍
Very useful video. Thank would will give it a try. 😃
goat status for showing the settings on doubling the ram that made blender run so much better
Awesome stuff, this will be a good substitute until I get Resolve Studio.
Thank you so much from Korea
Love you
nice
Jacob, I love the focused, stream-of-consciousness way you do this. I made it all through and learned what the various options and settings do (even if they aren't used). Thank you for putting this together.
Thanks a lot for your efforts.
Could you by any chance show how we can export the track to houdini... It seems that it's more than just exporting the cam as fbx.
It will be highly appreciated.
Thanks again
I’ll look into it but no promises with my busy schedule. I’d check to see if any others have found a solution!
Very good, in-depth tutorial!
I have a question: the castle scene at the end - was that all done in Blender or post was done in a video editor/compositor?
So for that shot, I actually used nuke to do my camera tracking, and then I use Cinema 4D to do the CGI. Traditionally I would've used blender for that project, but I was under certain obligations to only use Cinema 4D. After that, I took the CGI into nuke from my compositing and then sent it over to my color to do color and Vinci resolve for the final look. Hope that helps.
Hi Jacob, thank you for the great tutorial! I was wondering why when you rendered the cube with the shadow catcher there were 2 shadows. Is the footage casting light somehow?
Thank you! There were 2 shadows because I had two lights in the scene, a sun and point light. I didn’t really focus on matching the light of the CG world as I just wanted to focus on camera tracking but that would be the next process in order to add CGI into the environment.
@@Jacob_Zirkle I see, thank you for explaining
i just hope you comeback to after effects for your compositing tutorials, is waaaay more ""public"" than nuke
hi joacob amazing tutorial, at 28:50 when i try to orient floor, it gives me error 'three tracks with bundles are needed to orient the floor blender'. can you help me with it many thanks!
It just means that those 3 points together don’t really define a floor plane that blender can find. Try another set of 3 points and try again. Hopefully that helps
How to render with footage+VFX? 🙄🙄🙄 Why u didn't say.... everything went fine for me... Now my rendered footage has only added objects...no original footage 😢
You can composite over the real footage using any video editing software or compositing software like after effects or davinci (before people start bashing me that they are also used for video editing and motion graphics I know they do video editing too, but they are best at compositing that's why I counted that )
And for you brother if you don't wanna use those softwares you can do it inside blender too on the compositing and video editing workspace
Thanks for reading this ❤ peace
render (i think) -> film -> transparent
I can't solve a problem. The points solved are parallel to each other. It doesn't fit the perspective. So when I want to select the ground with 3 points, it makes a right angle to the camera.
ok buddy
Do you find yourself doing your camera tracking more in Blender or Nuke? Or does it just depend. Not too many tutorials out there for Nuke camera tracking in general.
Honestly really depends. If I’m doing a lot of stuff in blender I usually just stick to blender but when blender is giving me problems or I need to work across multiple programs nuke. I’m actually working on a nuke camera tracking tutorial so stay tuned
@@Jacob_ZirkleRight on! Can't wait!

How to enable 3d track
points 🤧🤧😭
hey ,
i'm facing problem in selecting three makers for setting the floor can any one tell me how to reslove the problem. it's showing three tracks with bundles are needed to orient the floor '
i tried alot but i got no use
fuck me too i somehow got it to work but than dont know what i did thought i click ctrl click instead of shift click to select the markers but that wasnt it.
ive done what you say, it was all perfect. I spent like 8 hours making 3D stuff on my footage, then i hit the render button, and its just the basic original video. All my 3D stuff is invisible and im trying since 30 min to make it appear in the render but nothing works. Does anybody knows how to render and export the footage WITH your 3D stuff added in it ??
Make sure you have whatever you want to render plugged into the composite node in the compositing tab.
@@Jacob_Zirkle thanks for your response. The compositing tab is the default onei didn't modify it. And how can I add my 3D stuff to it ?
@@jeremvfx should just need to have movie clip node and render node and then combine using alpha over node
@@Jacob_Zirkle yes that's what there already is in the compositing tab by default, but idk know why it still doesn't work
@@jeremvfx do you see anything when you view just the render node
i did everything what u said and i had 38.37 px solve error ;'(
That’s all good. Honestly you can have high solve errors at first and it’s not until you clean up the tracks for the first time that it goes way down. Look for any markers that might move off the mark or just try again from scratch. Camera tracking is a learning process and sometimes it can be a little finicky. I’ve had many times where I have to restart a camera track to change settings and then randomly it’s starts working. Just keep at it!
aka VFX motion tracking ni ham o'rgating iltimos
For a video i have a night time drone shot i could only get the solve error down to 2.51 px after cleaning a bunch. Is that enough for a good track?
Ehhh if you need the CG to touch the ground and not drift not really. If the CG is floating or you don’t need perfect sticking, then I think it’s ok but just know clients tend to not like imperfect camera tracks even if visually it looks ok.
Make a video on how to track green screen footage and how to remove greenscreen build set ... Want detail video
Working on something like that so stay tuned for a future video
nice try to improve your level
good but this vidoe could have been 12 minutes long
In my opinion it’s a great length, as he mentions a lot of key details and is a lot more intuitive to learn and remember. Also if your like me, I love blender so long videos are great :)
