Analysis of Motion Picture Processing Technology
The implementation of this feature relies on a three-tier technical architecture:
- frame-level analysis: Decompose the video into 25 consecutive frames per second and apply a face detection algorithm frame by frame (possibly using an MTCNN network)
- Motion Compensation: Tracking facial muscle movement trajectories by optical flow method to ensure that the replaced face maintains the micro-expression changes in the original video.
- dynamic fusion
The system can achieve 94.7% facial feature point matching accuracy in video files up to 6MB. The processing will intelligently skip blurry frames (such as dynamic blurring caused by rapid head turning), and prompt the user to select a specific replacement target when a multi-person scene is detected. The output video maintains the original encoding format and supports smooth 60FPS playback at 720P resolution, which meets the publishing requirements of short video platforms such as Jittery.
