Infinitalk AI Talking Video

Infinitalk is strongest when one portrait and one finished audio track are already driving the job. It fits talking-avatar explainers, podcast-to-video cuts, and narration-led character clips when the audio needs to remain the timing anchor and the output cost should scale with duration instead of a flat per-run fee.

On Rivya, this option is built around exactly one portrait image, one audio clip, an optional prompt, and two public controls: resolution and seed. Pricing currently follows verified audio duration, with 480p at 3 credits per second and 720p at 12 credits per second, which makes it a duration-led talking-video project rather than a generic image-to-video model.

The most important questions are whether the portrait is front-facing and clean enough for the avatar read, whether the audio track is already the take you want to keep, and whether 480p or 720p is justified for the job. Seed only really matters if you need reproducibility; most of the real decision lives in the source portrait, source audio, and resolution-cost tradeoff.

Rivya currently lists 3 credits per second at 480p and 12 credits per second at 720p. That makes it easiest to justify when you already have a finished voice track and want the video cost to scale with the actual spoken duration instead of paying a flat avatar fee for every run.

Choose Kling AI Avatar Standard or Pro when a fixed-price talking-avatar run is a better fit for short branded presenter clips. Choose Infinitalk when the audio track itself is the main driver and you want duration-based pricing tied directly to the portrait-plus-audio project.

Start here when the first result needs to answer whether one portrait and one audio file can already carry a believable talking-video pass. Use it for explainers, podcast-to-video tests, and narration-led avatar clips when the audio is already in hand.

This page uses one portrait image, one audio clip, an optional prompt, resolution, and seed. It is not a general-purpose animation tool; the first run should test whether that portrait and audio pair produces a usable talking result.

Before you run, make sure the portrait is face-forward and clean, the audio is the take you want to keep, and the resolution choice matches the budget. Start with 480p when you are just validating the talking-video behavior, and move to 720p when the clearer presenter output is worth the much higher per-second spend.

The page is public, but the actual first image-led video run is still gated behind sign in. Rivya currently lists 3 credits per second at 480p and 12 credits per second at 720p, so you can line up the portrait, audio, and duration expectations first, then sign in when you are ready to generate.

Stay on this page while you are checking one portrait-audio pair and checking whether the first talk pass is enough. Open the full Studio once the work needs saved versions, multiple avatar assets, or a longer production thread around the same character.
