why my floor isn’t aligning up correctly even if i have a decent solve error?
Here’s the video of the problem
You can’t just do the floor. You have to do the wall, too.
Keep track of multiple points. I don’t know if it will work even if I keep track of the points.
It’s possible simply as a way to fix something on the floor.
Add more…
i’ve already tried adding more but it’s the same thing when it comes down to set the floor
Eight points are required that are perfectly tracked throughout the entire frame.
However, we also need incomplete points for space recognition.
If you don’t solve this problem well, please share the video
I’ll make a sample for you.
Incomplete points so trackers that aren’t going through the end and how this can solve my weird rotation?
I really want to learn how to do it myself, I hope you can understand me.
To create the floor, you need the points of the triangle.
What we’re showing in this video is more like a straight line
This makes it difficult to distinguish between X, Y, and Z.

In the middle of the list of links, there is a lecture where you can learn Tracking in general.

This is a very complex topic and i’m sure “tips” like for example:
…are by far too short to learn even the basic aspects.
You may also look into the *Tutorial, Tips and Tricks& category like for example (almost random pick):

Thanks guys i’ll check this out.
@oo_1942 now i’m trying to create the triangle with my trackers. i will update here with my progress

i find out why the camera was moving weirdly… the problem was the focal lenght
(i shoot the video with an apple 14 pro) and this are the spec.
if i use them the camera rotate weirdly instead if i use this settings configured by blender they kinda work.
settings that blender choose for me
settings that in theory i should use
still the result isn’t worth but it’s far better
This is one of the things one can learn from tutorials: blender is guessing (in fact: computing) the focal length from the marker one gave it. Lots of markers → lots of data to use and decide which ones produce faulty values one should delete. But if the focal length and other data is know then there is no guesswork needed. 
i know the spec but they aren’t working :')
Camera settings are set when you know hardware information.
Most of them will be handled automatically by Solve.

There are more than the ones you know/showed and as said:
And as you said: it’s by far better then the few markers you tried initially.
And i never said it woul be easy

You need to know the size of the sense so that the focal length is applied.
Half of the information can be rather confusing.

The result depends on the size of the sensor.

in my case the sensor was 5.6x4.2 mm and the focal lenght and i tried to insert is 13 mm
i want to know why 6 was right for blender and 13 that is the one that the iphone gave to me was wrong
If the sense size and focal length are the same, it is the difference in the degree to which more accurate camera information can be used.
This doesn’t solve all the problems.
All of this has nothing to do with the current problem.
The failure to place objects in the current scene is the result of incorrect tracking.
A low value as a result of Solve camera motion may not be the result of normal processing.
Some markers may be poorly tracked, but may also show low error values.
The camera information mentioned above has been processed normally, but it is helpful when there is a slight error.

The focal length f is 2.2
