Part 1 Applications of Lip Sync Technique in Video Editing
Many editing software programs today include lip sync features that serve a range of purposes, from creating realistic lip sync animations to adjusting dialogue in different languages through translation.

Method 2 Make Lip Sync Effect In After Effects Without Plugins
If you prefer to avoid plugins, you can still achieve effective lip sync in After Effects. By utilizing keyframing and the audio waveform, you can manually synchronize your characters' mouth movements with the audio you’ve uploaded.
