What motion tracking does
Motion tracking pins a text element, label, or graphic to a specific point in your video. As that point moves through the frame, the text follows it perfectly. The result looks like the text is physically attached to the object or person in the scene.
You have seen this technique in sports broadcasts (player names following athletes), product videos (feature labels tracking with the product as it rotates), travel content (location names moving with landmarks), and social media (name tags following people).
Without motion tracking, text stays in a fixed position while the subject moves away from it. With motion tracking, text and subject move as one.
Traditional motion tracking vs. AI tracking
Traditional approach (After Effects, DaVinci Resolve): You manually select a tracking point (a high-contrast area on your subject). The software analyzes the pixel movement of that point frame by frame. You then parent your text layer to the tracking data. This process works well but requires understanding of tracking points, parent layers, and manual cleanup when tracking fails.
AI-powered tracking: You click on the object or person you want to track. The AI identifies the subject, learns its visual features, and follows it through the video automatically. No manual point selection, no layer parenting, no tracking cleanup.
The browser-based motion tracking tool uses the AI approach. Click on your subject, add your text, and the tracking happens automatically.
Step-by-step motion tracking
1. Open the motion tracking tool
2. Upload your video
Works with any footage. Best results come from reasonably stable footage where the subject is clearly visible.
3. Click on the subject to track
Click directly on the object or person you want text to follow. The AI identifies the subject and begins tracking its movement through all frames.
4. Add your text
Type your text, choose font, size, color, and position relative to the tracked subject. The text will maintain this relative position as the subject moves.
5. Preview the tracking
Play through the video. The text should follow the subject smoothly. If tracking drifts on certain frames, you can manually adjust.
6. Export
Download your video with tracked text rendered in.
Best use cases for motion tracking
Product videos. Label features on a product as it rotates in someone's hand. "12MP Camera" follows the camera module. "USB-C" follows the port. Clean, informative, professional.
Fitness and sports. Pin form cues to body parts. "Keep elbows in" tracks with the athlete's elbow. Useful for coaching content and technique breakdowns.
Travel and location content. Attach location names to landmarks as the camera pans. "Eiffel Tower" tracks with the structure as the frame moves.
Team introductions. Name tags that follow each person as they move. More dynamic than static lower thirds.
Cooking content. Label ingredients as they are added. "2 cups flour" tracks with the measuring cup as it moves to the bowl.
Before/after reveals. Pin "Before" and "After" labels to specific areas that change, tracking with any camera movement.
Tips for reliable tracking
Good contrast between subject and background. The AI tracks visual features. A red ball against a green field tracks perfectly. A gray object against a gray wall challenges any tracker.
Consistent visibility. If your subject leaves the frame or gets fully occluded by another object, tracking will pause or fail for those frames. Keep your subject visible throughout the clip.
Reasonable motion speed. Normal movement tracks cleanly. Extremely fast motion (fast pans, rapid subject movement) can introduce tracking lag.
Stable footage helps but is not required. Handheld footage works. The AI tracks relative to the subject, not absolute frame position. But very shaky footage adds complexity.
Good lighting. Well-lit subjects with clear edges track better than subjects in shadow or low light.
Text styling for tracked elements
Tracked text should be styled differently from static captions:
Keep it short. Tracked labels work best with 1-3 words. Long sentences attached to moving objects feel chaotic.
Use bold, readable fonts. Motion reduces readability. Bold sans-serif fonts maintain legibility during movement.
Consider background boxes. A semi-transparent background behind tracked text ensures readability against any footage.
Match the aesthetic. Tracked labels in product videos should feel integrated with the brand. Use brand fonts and colors.
Combining with other effects
Motion tracking pairs well with:
- Film color grades for cinematic quality under the tracked text
- Auto captions for dialogue while tracked labels handle visual elements
- Depth text for text that appears behind subjects while tracked text appears in front
- Zoom animations for dynamic reveals of tracked labels
Try it
Open the motion tracking tool, upload a video with a moving subject, and pin a label to it. The AI tracking takes seconds and the result immediately elevates the production quality.
