Che cos'è il motion tracking e come usarlo

Motion Tracking semplifica il monitoraggio del movimento di un oggetto e fornisce i dati rilevati al programma per ulteriori elaborazioni. Tracciamento del movimento include la registrazione del movimento dell'oggetto che corrisponde al modello di movimento precedentemente memorizzato. Ha una vasta gamma di usi, tra cui robotica, intrattenimento, sport, militari e intrattenimento. Inoltre, è stato utilizzato per la creazione di videogiochi e film. Mentre il motion tracking è spesso indicato come sport matching nell'industria cinematografica e dei videogiochi, in altri contesti è spesso indicato come motion capture.

A proposito, facciamolo!

Part 1. Learning to Understand Motion Tracking

We need to ask the really crucial question now that we have a fundamental understanding of what it is. What in the world am I going to do with this? In order to do that, let's quickly review some excellent applications for motion tracking. You could,

Utilize tracking information to stabilize motion
Add text or solids as additional compositional elements
Add 3D elements to 2D footage
Ujem dobovnih ali barvnih metod
Zamenjajte zaslone na računalniku, mobilni napravi ali televiziji

To so le nekateri primeri, kako je lahko sledenje gibanju koristno. Sledenje gibanju mora biti možno tudi v sestavah katerekoli kompleksnosti.

2. del. Katero programsko opremo potrebujete?

Za sledenje gibanju je na voljo veliko možnosti programov. Z prednostmi in slabimi stranmi smo sestavili seznam najboljših programov za sledenje gibanju. Po našem mnenju so to najboljši video urejevalniki za sledenje gibanju:

Film

Uporabite funkcijo sledenja gibanju, da dodate dramo vašim videoposnetkom. Ne boste se morali več bati, da bi se izgubili, saj ima FilmoraPro neverjetno preprost uporabniški vmesnik. Preprosto kliknite na osebo ali predmet, ki ga želite slediti, in izberite Sledenje gibanju iz menija Učinki.

Miscelatore

Un logiciel de suivi de mouvement open source et gratuit s'appelle Blender. C'est un excellent outil de création 3D. La modélisation, la mise en place de rigging, l'animation, la simulation, le rendu, la composition, le montage vidéo, l'animation 2D et bien sûr le suivi de mouvement sont tous pris en charge.

Kdenlive

Un suiveur de mouvement a récemment été ajouté à Kdenlive, un outil de montage vidéo open source et gratuit, dans sa section Effets. Ce programme analyse les informations de suivi d'un objet et génère automatiquement une carte du mouvement de l'objet. Ensuite, vous pouvez aligner un titre, une image, une icône et tout autre élément 2D sur l'objet en mouvement à l'aide de cette piste. Les algorithmes régulièrement mis à jour de Motion Tracker sont l'une de ses caractéristiques clés, ce qui se traduit par un taux de réussite de suivi plus élevé et une vitesse de suivi plus rapide.

HitFilm Express

La version gratuite de HitFilm Express est un excellent point de départ si vous apprenez les bases du suivi de mouvement 2D. Pour obtenir de meilleurs résultats de suivi, il offre deux types de suivi de mouvement : un seul point pour suivre simplement la position et deux points pour suivre la position, l'échelle ou la rotation d'un objet. Vous pouvez soit stabiliser la vidéo avec les données de suivi, soit changer le point avec un objet CG.

Sa technique de suivi par flux optique est exceptionnelle. Elle permet de suivre avec succès un objet en mouvement qui change de forme ou est voilé pendant quelques images en calculant le flux de luminosité de l'objet en mouvement. Les débutants peuvent donc gagner beaucoup de temps et d'efforts lors de la conception de réglages pour traiter des images complexes.

VEGAS Pro

In VEGAS Pro 18 and later, auto motion tracking is a freshly upgraded function. Despite its late birth, it included the Mocha masking and planar tracking technology, winner of an Academy Award. It enables you to accurately attach images and messages and even adjust for shifting perspective. You can hide faces, license information, and any private objects using this capability.

Adobe Premiere Pro

Because of its superior editing capabilities, Premiere Pro seems to be a requirement for anyone learning video editing. Premiere Pro, however, has a limited number of presets and automatic tools in order to provide consumers the most control.

When masking and blurring a face, motion tracking only works with the auto option. If not, you will need to enter and alter multiple keyframes to add text or resize the video, or you will need to install an extension to convert the mask's tracks to any transformed parts.

PowerDirector

Due to its simplicity of use, PowerDirector is unquestionably among the greatest motion tracking programs currently available. It accomplishes complex effects without having an advanced learning curve, in contrast to other video editing tools. As demonstrated in the introductory video up top, a simple interface may be used to easily track and manage one or more motion-tracked items.

With this program, creating a simple motion track may be done in only three easy steps. This editor is for you if you want to finish the job swiftly and painlessly and are new to intermediate video editing.

Part 3. Differences between camera tracking and motion tracking?

Making the audience forget that there is a camera in the room is one of the primary goals of filmmaking. To engage the audience, tracking shots like camera tracking and motion tracking are helpful. Tracking shots provide filmmakers the chance to immerse their audience more deeply in the storyline of their characters. I discovered that there is some ambiguity around how motion tracking and camera tracking differ from one another. I'll explain where the confusion might have originated and give you examples of how to use both strategies.

What distinguishes motion tracking from camera tracking? Their differences are due to how they view the course of action. From a camera's perspective, motion tracking monitors an object's movement. The scenario is more immersive thanks to camera tracking, which detects the movement of the camera and presents it as though you are in a virtual or augmented reality environment.

We'll examine tracking's development in the movie and its significance to the business. What it is and how it affects the cinematography industry. Along with the many software used for both motion tracking and camera tracking, we'll also look at some of the popular applications for both.

Motion tracking

Motion tracking is similar to a car pursuit on the highway in an action movie. Let's use a SimCity environment as another illustration: your Sim's movement is monitored against the steady scene of your home. The frame is set on your Sim, regardless of what your Sim does.

Camera tracking

When the camera must move and the object being "tracked" must remain stationary, camera tracking might be utilized instead of motion tracking. Information from a recorded live shot taken with a live camera is used for camera tracking. Then, using this data, a parallel virtual camera is projected in a three-dimensional composition frame. fresh 3D pieces are added while scenes are recreated.

On the Internet of Vehicles, motion tracking will be crucial. IoV will project the motion of your vehicle along the 2D path. Then, utilizing the information about your surroundings, you are informed of any potential roadblocks.

The same basic idea underlies motion tracking and stabilization. Both follow a moving target. When stabilizing, you choose the location where you wish to remain concentrated and centered despite movement. You track the object you wish to concentrate on while moving when you use motion tracking.

Sports videos frequently use basketball and football and use motion tracking. wherein the player is surrounded by a circle as he circles the court or the field for basketball.

Conclusion

In video editing, techniques like motion tracking and camera tracking are frequently employed. Even though they are frequently compared, both employ various vantage angles to depict motion. By following the moving object's movement throughout the frame, motion tracking maintains the moving object in focus. A post-production technique called camera tracking uses data from a pre-shot movie to project a parallel virtual camera that displays a 3D perspective. If motion tracking and camera tracking have anything in common, it's the way they draw the viewer into the tale and make them feel like a part of it. This gives your audience a sense of immersion in the story and enables your movie to linger in their minds emotionally and visually long after the credits have rolled.
