audio-to-video

To generate a video from an audio track, provide the file path to your audio and optionally a starting image to the fal.ai LTX-2 19B script. The process automates visual creation and matches the video duration to your audio.

Yes, you can create lip-sync and talking-head videos automatically by processing your audio track with fal.ai LTX-2 19B. This automates face animation and visual synchronization, eliminating the need for manual video editing.

Yes, you need a FAL_KEY for authentication to generate audio-driven video content. The Skill uses the @fal-ai/client to connect with fal.ai LTX-2 19B, requiring this key to authorize the video generation process.

When generating video from audio, you can customize starting and ending frames, video size, frame rate (fps), video quality, and camera motion. The system also supports auto-duration matching to align the video length with the audio.

No, a starting image is optional for audio-driven video production. The Skill can generate video content using only an audio track, though providing an optional starting image helps guide the visual output of the fal.ai LTX-2 19B model.

Your fal.ai audio-to-video generation might fail if the FAL_KEY is missing or invalid for authentication. Ensure your audio input is in a supported format and that the @fal-ai/client dependency is correctly installed.
