HeyGen v3 Lipsync (Precision)

HeyGen v3 Lipsync (Precision) is a lip-sync & dubbing model. Change what a video says — another language, or another take. Swap the audio on a video and put the lips back in sync. People run it for: lip-sync, dub, replace audio.

10 credits for a 5 s clip. It bills per second of output at 2 credits a second, so a shorter clip costs proportionally less. Billing stops at 480 seconds, so one run never costs more than 960 credits. Credits are the only unit we quote. One balance covers every model in the catalogue, so there is no subscription attached to HeyGen v3 Lipsync (Precision) specifically and no minimum spend to use it. See the pricing page for what a credit costs.

It accepts a video and an audio track. It will not start without a video and an audio track. Because this one is usually pointed at footage you did not shoot, a run asks you to confirm you have the rights to the material first.

Every run returns one video. Audio carries over from the source rather than being regenerated. Speech is re-synced to the lips. Runs are queued and processed in the background, so you can close the tab — the finished file turns up in your library. We do not quote a fixed wall-clock time: it moves with the length of the run and with how busy the queue is.

The catalogue also runs HeyGen v2 Translate (Precision) (5 credits for a 5 s clip), sync-3 Lipsync (10 credits for a 5 s clip) and VEED Lipsync v2 (2 credits per run) for the same job. HeyGen v2 Translate (Precision) is our default pick for lip-sync & dubbing. VEED Lipsync v2 is the cheaper way to do it, at 2 credits. They all draw on one credit balance, so trying a second one costs nothing beyond the run itself.
