After Effects CC2017 3d camera tracker error - Unable to decompose matrix 17:45

[RetroGrader808]

I have recently updated a project to CC 2017 and am doing a simple 3D camera track. its a long clip of 25 seconds. and it successfully tracks it all well with many tracking points but when i chose to make 3D camera i just get the error message - Unable to decompose matrix error - 17:45

follow by 'Cannot render because cameras parent has a zero scale. error 75:3'

is anyone having the same issue? any ideas on what i should do?

thanks

forgot to add that i then get these 2 error messages pop up a thousand times which i have to click through.

I have solved it by starting a new projected within cc2017 and bringing the clip in fresh to motion track it there.

I just try with a clean project and it still give same error.

I have same problem:

What trying to add a solid and camera after tracking and solving, I receive this:

"After Effects error: Unable to decompose matrix. 
(17 :: 45 )

I have also encountered the same error of the 3D camera tracker.

After Effects 2017 CC build 14.0.0.207

Unable to decompose matrix.

Yep, same Problem here. CC2017. Tried it so many times with different settings. Once I received so many error Messages Pop Ups AE crashed. Really annoying.

I am having the same issue myself

Is your camera parented to anything?

Have you updated to AE version 14.1.0?

This worked for me:

Next to shot type, change from "Fixed Angle of View" to "Variable Zoom"

Hope this works! ❤️

Thx MattD2410​! worked for me!

I'm new to after effect? Would you mind telling me how to  find shot type and change the setting?

In the 3d Camera Tracker effect, it's the first option in the effect controls.

This error is making After Effects unusable for me. I can't clear the error. My project can't open now without getting this dialogue that won't close.

Can you import your troublesome project into a brand new project?

[little fat girl]

Did not try that. I reverted to an auto save.

Incidentally, it did work eventually. However that bug is nasty. It shut me down for a couple hours.

hi guys, any solution to this? im having the same error. Happpens when i click 3d plane option

[Szalam]

Could you be a bit more specific about what you mean? When you say "3d plane option", what do you mean? Also, what is the exact text of the error message? Also, what are your system specs?

I'm the same mistake . AE 2017cc

[Mickinc]

!!SOLVED!!

I got the same error and i find a pattern to past by this error.

I add one frame before and one frame after the clip that i want to use 3d cam on.

I exporte it like that ( + 1 frame front, + one frame last)

I import it in a fresh session/ fresh sequence.

I crop(cut) de first and last frame of the clip

use 3d camera and the error dont appear anymore.

The trick is to dont have closed extremities

Seam pretty tricky but what you want i do, im not a programer at adobe!!

Don't know if this will work in your situation but it did in mine. I precomposed the footage and then adjusted the levels in the precomp lightening up the scene I was working with. I didn't quite blow it out, but I did bring it up enough that I could just barely see some compression artifacting. Then in my main composition (from which the precomp was spawned) I did the camera tracking. It's worked like a charm 3 times now in different projects.  I have noticed this seems to happen to me when I use dark footage or footage with not a lot of moving colors with h264 compression like ones shot with a iPhone. Hopefully this helps.
