I need some help. Been trying to fix this crashing for a few days now and just cant find anything that works. When I apply 3d camera tracker to my footage evrythign works fine until it getrs to solving camera and then after effcts just instantly crashes everytime. I have tried to use different footage that I have used 3d camera tracker with before and still, it crahses. I have cleared all my caches and reset my prefferences and updated after effects and my gpu drivers to the laterst versions and it still continues to crash everytime it reaches solving camera.

My PC:

GPU: Radeon RX 580

CPU: Intel Core i5 3.6GHz Coffee Lake

RAM: 24GB Hyper-x Fury

Are you using the Motion Tracking Workspace? (it makes a difference) What kind of footage? What frame rate? What frame size? What Codec? How long is the shot? What are your memory and disk cache settings? If you have starved other apps in Preferences Camera Tracker will probably fail. You need at least 4GB for other apps. All of these things may play a part in causing the crash.

Try using this footage from Adobe Stock 296416718 and see if you can get a good camera track. I got a very low error with advanced analysis turned on, set an origin and ground plane to give me a nice starting point.

Then I added a few solids with grids as guide layers to verify the track. If that footage from adobe stock, which you can download for free, does not give you a good camera track then the problem is with your footage, the length of the shot, or the kind of a shot you are trying to track.

Hi, I am using the motion tracking worspace and I currently have 6GB reserved for other applications. The footage is just a shot from a video game and it's 25fps with a resultion of 1920x1080 and its H.264 codec. My current memory and disc cache settings are as follows: Maximum Disc Cahce Size : 100GB (its on my F drive as I have no space on my SSD but i had the same crash when it was on the SSD) and my memory settings are 24gb installed, 6GB reserved for other applications and 18GB available for AE only. Sadly I am unablke to download the stock footage as it seems to be unavailablefor my account (might be because its a student license) so if there is any other footage you know tracks well that i can try let me know. However the strange thing is even when I se footage i have succesfully moton tacked before i still recieve the crash.

Thanks for your help,

Henry

It could be the kind of shot you are tracking. Most video games are created with unrealistic virtual cameras and AE's camera tracking algorithms are based on actual optics, perspective, and parallax changes. Unless the perspective and parallax shifts are accurate the camera tracker cannot solve for camera position. This could cause a mathematical overrun that causes a crash.

Show us the footage. Try tracking the sample footage I posted a link to. If you can track the sample footage but you cannot track your game footage, the footage is the problem and you will have to use other techniques to try and track movement. The link I provided to the sample footage has the option to download a preview. You do not need an Adobe Stock account to download sample images or footage.
