robot TL;DR:

Wondershare Filmora resolves audio and video delays through either an AI Auto Synchronization tool or precise manual waveform alignment.
    ● The automated method requires selecting both media files on the Editor Timeline and executing the Auto Synchronization function located within the Tools menu.
    ● Manual synchronization involves visually matching audio peaks on the timeline waveforms and splitting the tracks to delete mismatched sections or dead air.
    ● While Kling AI generates video, it lacks native editing and auto-syncing capabilities, which Filmora provides alongside integrations for Kling AI, Veo 3, and AI Audio Denoise.
