It's really great that the geometry used for tracking can be used directly as shadow catchers and masks. I will subscribe it when the beta is finished!

@@juanfxblender Hey! Currently, GeoTracker for Blender is available as a beta. With this add-on, you can also track head movements. However, it doesn't support tracking of facial expressions or emotions. For these specific purposes, there's a separate plugin called FaceTracker, which is currently only available for Nuke.

@Rocketman1105Gaming 10 месяцев назад

This looks very interesting. Why do all the tracking tutorials show such easy shots though? In my years as a matchmover, I don't think I have ever gotten a shot that clean haha. Something like that realistically would just be autotracked. It will be interesting to see how well this holds up under more challenging shots and if it is actually better then blender's stock tracking. I could potentially see this falling apart under extreme motion blur or occlusion. Going to have to give it a go and find out. Very nice to see blender tracking getting some love and attention regardless.

@nickdale6660 9 месяцев назад

Right - I never see anyone do a complex camera shot involving actual people crossing the frame etc

@keentools 9 месяцев назад

Hello there! You can explore a more complex shot in our GeoTracker for Blender demo video, for example. Our basic tutorials are designed to demonstrate the add-on's functionality on relatively straightforward shots, but we're open to the idea of creating more advanced, not basic, tutorials.

@nickdale6660 9 месяцев назад

@tomspiers2087 11 месяцев назад

I'm very interested in Geo tracker for blender and After Effects but I'm also pondering getting synth eyes. Cost wise it's an interesting comparison for roughly 2 years of Geo tracker annual subscription I could buy Syntheyes outright. Synth eyes seems to have a deeper richer feature set but GeoTracker works directly within AE and Blender. My question is how would this kind of camera tracking in Geo traker hold up in a production environment with more troublesome shots. Could GeoTracker be relied on as a camera tracker for all situations or would there be times its geometry based approach would fail where Syntheyes could potentially get the shot. I have to say the subscription model for GeoTracker is off putting. The ability to buy outright would make it more attractive in this comparison for me.

@iPEMiC. 11 месяцев назад

Hi, we love what you guys doing here! We also have concern and question about some footage coming from GOPRO 11 shoot on top of FPV drone where we got issue to track the camera because of it wild angle view distorted + some blur because of the setting + ReelSteady already apply when we receive the footage, so we was looking if you have any documentation or reference tutorial for this type of camera please ?

@keentools 11 месяцев назад

Hey! Our tracking system is optimized for undistorted (linearized) footage. When there's significant distortion, especially with post-stabilization tools like ReelSteady, it can impact the accuracy. For the wide-angle distortion, there are third-party software solutions that might help. Not sure about the exact software for your case, but it's definitely something worth exploring.

@iPEMiC. 11 месяцев назад

@@keentools We used AE as third-party software for the distortion, ok then we will have a shoot. Thanks!

@ICE0124 9 месяцев назад

Also one thing you can do so the colors match better is go to Output Preferences > Output > Color Management and then select override and then set the view value to Standard instead of Filmic. It will make your colors more accurate and true to what they should look like.

@cgcursor4910 10 месяцев назад

can you make tutorial for taking both camera and objects at the same time ?

@keentools 10 месяцев назад

We'll think about it! Menwhile, I can briefly desribe how to do both camera and object track. We recommend first capturing the camera movement by switching to 'Camera' tracking mode and then selecting this tracked camera in GeoTracker to track the object.

@cgluca 7 месяцев назад

what about if you have a camera rotation of 180 degrees or more ?

@keentools 6 месяцев назад

If you have a rotation of more than 360 degrees, you can press the Unbreak Rotation button in the Scene tab. This will help avoid 360 degree jumps, if that's what you're asking about.

@PhilFlock 3 месяца назад

hey there, i have a question i cant find an answer to. hopefully you can help. i try to track my camera AND the object seperatly. For example i have a moving camera shot of a car. and lets say the camera spits out a fluid. i of course need to track the car but also the camera so the fluid can collide with the surroundings. thank you for your help. Cheers!

@keentools 3 месяца назад

Track camera first using some static object in the background. You can also get a camera track using built-in Blender tracker. Then create new GeoTracker, plug that camera into Camera input and now track the moving object.

What methods might you suggest for tracking an actor on a green screen with tracking marks?

@keentools 10 месяцев назад

Hey! Apologies for the late response. If you're looking to track an actor with tracking marks on a green screen, it's essential to know that GeoTracker is not the best tool for deformable objects like a full actor. GeoTracker is suited for rigid geometries.

@kieronestrada6402 10 месяцев назад

No worries, thanks for response. However I was referring to the tracking marks being tracked, my mistake for not better explaining...and wondering which would be better for those small markers...objet or camera? Blender tracker is pretty decent for small markers. @@keentools

@MasBagz 11 месяцев назад

How to define that the statue. shadow may a cause a problem ?

@keentools 11 месяцев назад

Hey! In our tracking process, we're matching geometry with the image. Since our geometry is a flat surface without any tree or statue, elements like these can cause issues because they move differently (parallax). So, we mask parts covered by trees (and a statue) to ensure smooth tracking. Similarly, if you were to track, say, a microphone in someone's hand like in our demo video, it would be advisable to mask out the microphone's handle where it's held. This is because the model doesn't contain geometry of a clenched fist, and thus the parallax could compromise the tracking accuracy.

@MasBagz 11 месяцев назад

what happens when camera it is moving and the object i want to track it is also moving?

@kurokishizx Месяц назад

YES I NEED A ANSWER TO THIS

@kurokishizx Месяц назад

does this work with video reference import into cam?

@keentools Месяц назад

You pick a static object in the video, import a matching geometry, place it on to of the object, switch to Camera tracking mode and then press the tracking button. This way you animate the camera that is plugged into the Camera input. That's how it works.

@JackSatisha 11 месяцев назад

precalc has problems. check it, anyone know the solution? Thank you.

@keentools 11 месяцев назад

Hey! Please make sure that the analysis range for the start and end frames contains images in the footage. You can check this by scrolling through the footage in pin mode from the start frame right up to the end frame. It's possible that the frame range for analysis is more extensive, either at the beginning or the end. If everything looks okay, then you should re-analyse. In short, this error means that there are no calculated frames from the analysis file in the selected tracking range, suggesting some frames might be missing.

Hey! You can actually use just a default cube to track the front part of a house. It will work. This means you don't necessarily have to model the entire house.

@Looki2000 10 месяцев назад

How do I make a model for tracking without knowing the focal length?

@keentools 10 месяцев назад

Hey! You can actually use just a default cube to track the front part of a house. It will work. If you don't know the exact focal lenght, you can tick 'Estimate focal length' checkbox to get that value calculated for you. Just remember, you need at least 4 pins set on the wireframe for it to work, and it only estimates for the current frame while pinning. Hope this helps!

is there a possivilitty to track points with this method like tracking points...not just geometry

@keentools 11 месяцев назад

Hey! Unfortunately, I don't fully understand your question, but GeoTracker is a geometry-based tracker. It works by tracking special 2D points throughout the video. Initially, it analyzes and tracks these points, and then utilizes them to track the geometry.
