About the PD Movie LIVE AIR 4 Smart
LIVE AIR 4 SMART
50M Seamless Focus, Limitless Possibilities
How can we compress extensive functionality and performance into the smallest possible energy footprint—and push that energy to its physical limits? This is the question we’ve been exploring from the very beginning. LIVE AIR 4 SMART is the embodiment of that philosophy. By utilising three LiDAR scanning modes—point, line, and plane—we’ve developed an innovative variable-zoom LiDAR system. Combined with an AI-powered virtual focus algorithm, it delivers multiple breakthroughs within an ultra-compact body: up to 7 hours of battery life, high torque, and long-range autofocus. This isn’t just a refined use of physical space—it’s a redefinition of what’s possible at the intersection of form and performance.
Farther & Stronger
A Classic, Upgraded
The all-new MOTOR SMART features an optimised indicator layout and enhanced motor torque. While retaining all the core functions of the previous generation—including the precise short-range LiDAR module—it now introduces a newly developed long-range variable-zoom LiDAR module. This innovative integration of dual LiDAR systems for both near and far scanning enables a full-dimensional breakthrough in performance.
HYBRID ZOOM LIDAR
The core philosophy of the hybrid zoom LiDAR system is to push both hardware performance and internal space utilisation to the absolute limit—with zero waste and zero compromise. We concentrate all available energy into a 4° laser point, enabling scanning distances of up to 50 meters. Building on this, optical zoom technology transforms the 4° point into a 16° laser line, striking an ideal balance between visual coverage and scanning depth. For close-range scenarios, a 28° laser plane provides a much wider scanning angle, effectively covering areas like the face, hands, and upper body—enabling smoother and more comprehensive subject tracking at short distances.
Comprehensive Algorithm Upgrade
Core AI Intelligence & Virtual Lens Modeling Technology
LIVE AIR 4 SMART features a dual upgrade of both hardware and intelligent algorithms. With enhanced processing power and broader compatibility, it breaks through the autofocus distance limitations of the previous-generation LiDAR motor—enabling significantly longer autofocus range and unlocking a wider variety of use cases.
Multi-Angle Scanning Combination for All-Scenario Coverage
1 + 1 > 2
The hybrid zoom LiDAR system combines a fixed wide-angle 28° scan from the short-range LiDAR module, with a variable narrow-angle 4°/16° scan from the long-range zoom LiDAR module. This configuration creates multiple autofocus scanning modes, enabling the use of different focal length lenses to shoot subjects at varying distances—achieving maximum autofocus adaptability.

AI-Powered Virtual Intelligent Focusing
Wide-Area Array Focusing + Narrow-Area Precision Scanning
· The short-range LiDAR projects up to 4,096 distance-measuring points, delivering high-density, fine-tuned autofocus for close-range subjects.
· The long-range zoom LiDAR features 1,024 high-intensity, high-penetration points, enabling precise directional scanning and accurate focus on distant targets—greatly expanding focusing range and depth detection capabilities.
· The system integrates AI-based virtual data learning, allowing it to intelligently record and learn autofocus paths during shooting. When complex scenes with overlapping near/far subjects or sudden movements are detected, the system predicts a safe focusing zone and locks focus instantly—reducing focus hunting and significantly enhancing stability.
· When a subject moves beyond the LiDAR’s effective scanning range, the system uses learned object speed and focus behavior to predict its movement trajectory within the 50-meter range—achieving AI-driven virtual remote autofocus.
· No complicated cables or setup required—just power on and shoot. Intuitive focus control lets you concentrate fully on creation, boosting both visual stability and expressive potential, and helping deliver more creative, cinematic results.
Hybrid Focusing Mode
Simultaneous Use of Short and Long-Range LiDAR Modules
Narrow-Beam Focusing Mode
4° Point Focusing – Precision in a Class of Its Own
In Hybrid Mode, both the short-range and long-range LiDAR modules work together: When the subject is within 5 meters, the system prioritises data from the short-range LiDAR for precise measurement. Once the subject moves beyond that range, the long-range LiDAR seamlessly takes over—maintaining stable and accurate autofocus across varying distances.
Double Power Mode
Higher Frame Rates, Every Frame in Focus
Fore/Back Focus Switching Mode
Focus lock on the nearest or farthest object within the LiDAR scanning range.
Master–Slave Mode
It can both transmit and receive—functioning as a follow focus and a LiDAR controller.
Manual Control Mode
An ultra-low-latency, fully wireless follow focus powerhouse.
When MOTOR SMART is powered via USB-C and the battery level remains above 95%, the system will automatically enter Double Power mode. In this mode, the LiDAR distance measuring refresh rate can reach up to 960Hz, and the motor’s instantaneous peak torque can reach 1.2Nm, ensuring that as long as the LiDAR detects a target, the system can achieve frame-by-frame focusing, with every frame clearly visible. (As long as USB-C power is connected, Double Power mode can be maintained for a long time. This mode requires the motor to be set to the fast focusing level.)
Open Data Protocol
The upgraded MOTOR SMART features a USB-C port for both power and data transmission. With User Manual support, control access and LiDAR data are open to third-party systems—ideal for integration with robotics, arms, and other large-scale mobile rigs.
LiDAR in Real-World Applications
The LIVE AIR 4 SMART is highly versatile—ideal for professional film crews, small indie studios, or solo shooters—delivering stable and efficient focus control for any setup.
Three Adjustable Focus Speeds
Cycle blinks three times = fast speed
Cycle blinks twice = medium speed
Cycle blinks once = slow speed
High Speed
Fast and responsive—instantly locks onto the subject. Perfect for capturing fast-moving action.
Medium Speed
Balanced and versatile—ideal for most general shooting scenarios.
Low Speed
Smooth and subtle transitions—perfect for cinematic shots with gentle focus shifts.
Compatible with Most Manual Focus Lenses
The LIVE AIR 4 SMART autofocus system works with most manual-focus cinema and DSLR lenses that have built-in focus stops. It also supports certain electronic DSLR lenses without hard stops—especially those with depth-of-field scales and linear manual focus capability.
