If you've been using the 3D Camera Tracker a couple of times I bet that you have come across the following issue before:
'No depth from a tripod pan solve' shows up at the bottom of the target icon and the icon sits flat on your footage. You may also notice that all of your track points are the same size, indicating they are all equal distance from the camera. What is going on?
When you walk along the street you may notice that static objects at different distances seem to be moving at different speeds. The further they are away, the slower they seem to move. The closer they are, the faster they seem to move. This is called the parallaxing effect.
The 3D Camera Tracker uses this effect as a basis to figure out how far object are from one another in your 2 dimensional footage layer. However, if the camera does not move around the scene very much, e.g. it is mainly a panning movement, the tracker cannot derive any depth information because there are no parallaxing objects in your shot.
In those cases, the 3D Camera Tracker might determine that it is a panning shot and not give you any depth information with the warning 'No depth from a tripod pan solve'.
But that isn't a reason to panic as this warning is usually not a problem. Why?
Because the camera does not move around within the depth of the scene, you can attach objects to the 'flat' track points oruse the 2D motion tracker I demonstrated in this Adobe After Effects tutorial to link other layers to your camera's movement and it will almost always work just as good.
So don't freak out when you see this warning, it's simply telling you your scene does not contain any depth information - and for most tracking scenarios it won't have to.
Finally, let's look at some properly tracked footage and what you can do with it. And even here, there might be a few common problems that are worth exploring.
I come to find that blog posts worth more that your youtube channel. yhank you!
Sir while running tracker after effects stopped working what ido
What do you mean with 'stopped working'?
I've had the same issue... it goes into "solving camera" and, after 20 or 30 seconds, a window pops up saying that After Effects has stopped working and will close out.
why does mine get stuck on "solving camera"?
my footage is on 60 fps so its not that blurry and it has plenty of stuff to track and no one is moving except the camera
Maybe your footage is too long or too complex? Try bringing it down to 30 fps (you can pre-compose it so you can speed it back up later) or tracking only a part of it to see if that works.
Same problem, did you solve it?
thank you Tobias
I created null object and camera when ‘No depth from a tripod pan solve’ is shown but null object dosn't move with the track points It looks like that It isn't attached to the track point.
What should I do?
Have you created your camera? Does that move along properly with your footage?
I have created camera but it doesn't move!
Hi Tobias, I am curious how to adjust camera tracking once an error occurs. Example, I am tracking two separate objects (both applied as two solid camera layers), everything is set up and tracking fine, then all of a sudden "Error". Now on replay I have this red bar over some of my footage and one of my tracked layers is floating off it's original path. Is there a way to go into the camera tracking and fine tune it back? Thank you!
Unfortunately, the 3D Camera Tracker is not a perfect tool and, depending on your footage, may encounter parts of your video that it simply can't track. You can try to adjust its setttings (e.g. try Detailed Analysis) or delete some of the track points that might throw it off, but if that doesn't help you may have to think of a different solution. You could try Mocha (I have a few tutorials for that on my YouTube channel) or break up your video into different sections that you can then track separately
Hi my track points are not showing but when i click render track points they are there what is wrong?
Man the "mask" trick just saved my life. Thanks a lot! This article is incredibly important for all 3D tracking AE people !!
When I had text after tracking it won't attached to the footage. It change its position like normal text.. can u pls suggest what's going on???
Sorry I do not understand. How did you attach the text to the footage?
Hi tobias, I've got a lil' problem, I succesfully tracked my target where I wanted to be tracked,then when I preview it, it went well but when I pair the blood splat layer to the null object, the blood effect was just floating around the scene.It was bad kids man...bad kids.how do I fix it?
PS: I watch the "PANNED bullet hit tutorial with a moving camera"and it is where the I knew about the tracker thing.I thing I still need to track Camera my footage.
Hi, sorry for my slow response. Have you resolved your problem by now? How are you linking the blood splatter to the track? Have you ensured that the solid you created along with the camera is properly following your footage? If not, your track might not be very solid. Also, a good place to ask your questions is on myForums
AE works fine for me most of them time but is there a better program to more accurately 3d camera solve? I have a big project coming with a lot of after effects camera tracking so the time its takes is also a factor.
You can look at some more dedicated tools such as Mocha Pro (now available as plugin for Adobe) or Syntheyes (not too expensive) and you can even track within Nuke
Red target marker is not showing up. What should I do? Thanks in advance
Maybe it's just so small that you can't see it? Sometimes the 3D Camera Tracker's scale can be way off depending on your footage
Same here....no matter what I try I just dont seem to be able to get the red target to appear, even though the footage seems to have tracked OK???
Have you ever encountered a problem where in Mocha Pro, you solved the camera and copy its data into AE CC2019, but when you try to paste the mocha camera, it doesn't give you the option?
I've only ever had that issue with old version of the standalone version of Mocha which required a separate plugin for AE to copy/paste the data across. What version of AE and the plugin are you using?
