No install needed.</a><h2 id="how-it-works">HOW IT WORKS</h2>Step 1. Upload your portrait. A clear, front-facing image with the mouth, jaw, and chin visible. This becomes the character in the video. Works great with: headshots · anime characters · AI-generated faces · character rendersStep 2. Upload your audio. Speech, narration, or singing. The workflow separates the vocals from any background noise on its own and trims to 8 seconds.Step 3. Write your prompt. Describe the character and the performance, like "anime mecha pilot speaking with focused determination, accurate lip sync, natural blinking." Describe the performance, not camera moves.Step 4. Hit run and download. Three passes generate and upscale the clip while your audio drives the mouth. You get back a 10-second 1080p MP4 at 24fps with the audio embedded. Ready for: Premiere · DaVinci Resolve · After Effects · YouTube · TikTokFirst time? Upload a front-facing portrait and an audio clip, edit the prompt to describe your character, and leave everything else as-is.<h2 id="overview">Overview</h2>This workflow turns a portrait and an audio clip into a lip-synced video using LTX Video 2.3, an open-source audio-visual model from Lightricks. It reads your audio, not just a prompt. A separation model pulls the vocals out of the track, the LTX audio encoder turns them into features, and the model generates mouth movement, timing, and jaw motion that match the speech. A static camera LoRA locks the frame so the face stays centered the whole time. A three-pass pipeline builds the clip at a small base size, then upscales twice to reach 1080p, with detail LoRAs sharpening the face along the way. Because the sync reads sound, not words, it works across languages. You upload a portrait and audio, write a short prompt, and get back a 10-second 1080p clip in about 2 minutes 46 seconds. No setup, no nodes to wire.Who it's for: creators, animators, and course makers who want audio-driven talking characters in ComfyUI without wiring a multi-pass lip-sync pipeline from scratch. Not for: a fast one-click clip. This is a heavy render, and the source portrait and clean audio decide most of the result.<h2 id="why-floyo">Why Floyo</h2>Floyo is the only ComfyUI platform built for teams in the browser.<ul><li>Made for teams.
