I'm quite new to Blender and have been trying to get into camera tracking for my movies for a while now. I have gone on lots of forums and watched many tutorials but can't fix this problem. Whenever I track a scene and simply test it with a cube, the cube starts moving around and spinning about and things like that. I simply don't understand as I'm very new to this. I have got a movie clip off of a YouTube tutorial and tried to add a cube to test it and the same thing happened. I'm not quite sure how else to explain it, but the cube just keeps moving around.  Please help,  Thanks.  EDIT:  Here's the file:    NFT

Whenever I do camera tracking in Blender the reconstruction is always zooming out or not on the axis. I have a great quality camera, but the end results of the camera tracking always has the model sliding. If you have a solution please tell me.

In the camera setting in motion tracking, how do I tweak the K1, K2 and K3 value properly. I was told that these values are not necessary to tweak but I do want to adjust it, just for the sake of perfection.

I have motion tracked my camera in Blender and have been trying to import it into 3d max. When I export it as an .fbx, the camera, when I import it into Max,  is facing the opposite direction to what it was in the Blender scene, and the animation that was on the camera, is on the geometry. I tried to change the forward axis of the camera in the export settings but this didn't effect the direction of the camera at all when I brought it into Max.   I tried an .obj, but only the geometry imported and it was all squashed together, and the camera didn't import at all.  So then I tried to export as a .dae, but although the camera is facing the right way, the tracking is completely off and very rough and jumpy, whereas it was perfect in Blender. Can anybody help me out here?

I already searched the internet but could not find a solution to this. Maybe it is the same question as  but there was no answer.  I want to render a video with tracking, but the output "loses" color information and gets kind of greyish. I first thought that it is related to the renderer, but it happens in Cycles and Eevee. Therefore i made a sample image, added it to the image sequence editor and rendered it as 1 frame. Resulting in the same problem.  I placed the original image beside blenders output so that you can see the difference. The only idea I came up with is that something with the lighting is not correct but I can't find a setting for that.  I am using Blender 2.80 with the default settings. Only set the output resolution to match the input resolution.

So  i have a scene with a few objects, and a water simulation in the scene. However I want to animate the camera turning around in the scene, while the water simulation is frozen in time. So something like a time freeze effect. But when ever I try to render an animation it renders the water simulation too. I just need one frame of the water simulation. Is there a way to do this?

Some shots I see online I don't understand how the tracking is done.      The car is coming at the camera while the motion blur is also towards the camera, so if you move your camera in the direction of the motion you will also blur the car. I guess these photos are a complete photoshop job?

I'll try to keep it clear: I want to use a background in Blender and for that I use a plane that I want always to fit the camera viewport.  I wanted to do it cleanly, so I put a plane at the same location and orientation as the camera and now I want to move the plane along the camera axis and change it's scale to always fit the viewport (what you can see in the camera view).  I used cos and sin with the FOV of the camera to move the plane but I didn't have anything correct (not so good at math...) and I don't get how I can have the plane to always fit the viewport (fill it entirely).

Trying to follow along with a tutorial and in that tutorial the idea is to look at an object I created from the front and then set the camera to the current view.  The steps to do this are:   Numpad 1 (Front perspective) Ctrl+Alt+Numpad 0 (Align Camera to View)   For some reason whenever I do this I don't see anything in the camera and then panning the view around I see that my object seems to have moved to where I wanted the camera and my camera hasn't moved at all.

I am new to blender (yes, laugh at the obligatory doughnut) and I when I set up the camera (I use NUM 0 to access the camera and move it into position with &quot;Lock camera to view&quot;) in the viewport it shows as the first attached image, but when I render it the image is further back as shown in the second image. Is this normal behavior or am I missing something?

I'm trying to follow along with a blender beginner tutorial, and I'm having trouble with spot lights. All other lights seem to work fine but I can't get spot lights to work.    Light isn't really doing anything to the scene, I can delete it and it'll look the same.  You can find the blend file here -

It's kind of an interesting result.  Here is how render viewport should look on frame 1:    Here is what happens when I press F12:    It's like I have a second camera (although I don't) somewhere below. What is even weirder is that If I place the camera behind the wall...    it shows everything correctly (example cube is seen):    As you can see, my camera is following an object that is on Bezier curve WHILE being on Bezier curve (right) itself. This animation is working perfectly on rendered viewport but not if I use ctrl+F12. Just the same grey viewpoint.  What could be the issue?

I'm trying to do object tracking using Blender 2.71. In a youtube video the guy simply clicks "Object Motion" in the Solve tab.  His Screen:    My screen:    But I can't find this option.    Can anyone help me please?

Is it possible to track an handheld shot (there is already an answer on here about tripod shots: ) that doesn't have any visible points in common between the first and the last frame? As an example, imagine a shot of someone driving in a car for thirty minutes. Obviously everything from the first couple of seconds won't be there anymore at minute 15.

I want to have a camera, that follow the player, without childing it to the player object. So far I have this one line, that follows the player, but does not rotate with it (meaning the camera should look where the player's front is looking, how can I do it?  transform.position = player.transform.position + offset;

I just started blender and one of the main things you have to do is to render to make an animation, but I can't seem to do that. Whenever I click Render and then render image or render animation, at the top of the screen it says 'No camera found in Scene "Scene". I don't know why this is happening.

I went to animate a project, Blender was returning a blank screen.  I have attempted to restart both Blender and my laptop, as well as re-downloading the program.  With each attempt, Blender exported a black movie, which I attempted to watch multiple times.  I even attempted to reanimate one of my older Blender files, and even that reexported as a black movie.  I have attached a picture of what I see when I render. Please Help! Thank you!😀

I am using camera tracking to make a short film and in render viewport you can see what I am trying to add (yes, those are butterflies).  After rendering the scene the butterflies appeared transparent    As you can see in the first image my material is very basic on the butterfly.   Here are my compositing nodes:   They are the default camera tracking nodes... in blender internal.  I am using blender v2.77 on windows 10 with the cycles render engine.
