Lipsync Image Labs — image input
Lipsync Image Labs accepts a still image instead of a video. It generates a lipsync result from a photo — useful when you have a reference image but no recorded footage.
When you select Lipsync Image Labs, the input control switches from Video to Image.
Switch your model
Open the model selector in the top-left corner of the Lipsync page. Selecting a model immediately updates the input controls in the bottom bar.
Start with LTX Lipsync on a paid plan for unlimited, fast generations. Switch to Lipsync Video Labs when you have a video source. Use Lipsync Image Labs when you only have a photo.
Once you've picked a model, see Prepare source files for input guidelines and Create a lip-sync video to generate your first result.
