Long time PFTrack user here. I am confused as to why the Auto Track feature has become so stripped down as well as the logic behind other changes. I am afraid shots that were a doddle to track in previous versions are becoming nightmares to track in this newest release.It seems far less accurate, capable, and tweakable. Is there a way to revert my version back to 23.08.14?
This newest version is almost unworkable for us.
Hello, Jaime. Thanks for taking the time to provide feedback and joining the community.
If you could send over some example shots, we could give you some feedback and suggestions on how best to use the new tools. Feel free to contact support through in-app messaging, and we’ll take a closer look if you are struggling with a shot.
I can explain the parameters in relation to the legacy tool to clarify:
Image Proxy: This was previously used primarily to increase tracking speed, but you should find the new node is much faster. If you need to pick features at a smaller resolution, you can use the new Feature Scale parameter.
Deformation: The feature windows will deform automatically during sub-pixel refinement. You can keep a running measure of this deformation by setting the Feature Template option to Adaptive.
Consistency: The Motion Prediction parameter now controls this. It can use image motion or metadata hints to help.
Back-track and spread: This is no longer needed as the new filtering algorithm will automatically pick the longest available trackers to cover your image area as best as it can.
Blur, Illumination: The new feature matching algorithm uses an illumination-independent image descriptor, so you shouldn't need to pre-blur the frame or tell it to account for any brightness variations.
We recommend attaching a User Track node directly beneath the Auto Track node and using the Fetch button there to fetch any tracking points you need to adjust. You can use all the tracking tools available in the User Track node to fine-tune or extend any tracking points as needed.
I will link you to a couple of quick videos that will show you how to disable and manually adjust trackers generated using the Auto Track.
