Resolution
In short: Resolution is the number of pixels in each dimension of a video frame, directly affecting the visual quality and detail of lip sync output.
About Resolution
Resolution defines the pixel dimensions of video content, with common standards including 720p (1280x720), 1080p (1920x1080), and 4K (3840x2160). In lip sync, resolution impacts both quality and processing requirements: higher resolutions demand more computational resources but produce finer detail in the generated mouth region, including subtle textures in lips, teeth, and skin.
Many lip sync models process faces at a fixed internal resolution and then scale the result to match the source video. The gap between internal processing resolution and output resolution is bridged by super-resolution networks, making the choice of processing resolution a key trade-off between speed and quality.
How Resolution Connects to Lip Sync
Resolution relates to several other concepts in the AI lip sync pipeline: Upscaling / Super-Resolution , and Frame Rate .
