## InfiniteTalk

InfiniteTalk is an AI lip-sync and talking-video generator that turns a single photo or an existing clip into a full-body, audio-driven performance. Its sparse-frame engine synchronizes lips, head motion, posture and micro-expressions, and it is built for long-form output such as podcasts, audiobooks and lectures where most lip-sync tools break down.

**料金とプラン:** Credit-based, in two parallel formats. One-time credit packs cost $9.9 (90 credits), $49.9 (670), $99.9 (1,610) and $199.9 (3,630), with effective rates from about $0.11 down to $0.055 per credit; those credits never expire. Monthly subscriptions use the same tier prices — $9.9, $49.9, $99.9 and $199.9 per month — but grant more credits each month (roughly 100 to 4,440). Commercial use licenses begin at the Pro tier, and payments run through Stripe.

- **State-of-the-art lip accuracy:** Synchronizes mouth shapes with the exact phonemes of your audio using phoneme-to-viseme mapping, so every syllable lines up with the visual movement.
- **Infinite-length generation:** Generate hour-long videos — podcasts, audiobooks, lectures — with no technical duration limit and no drop in character consistency.
- **Full-body synchronization:** Head motion, torso posture and micro-expressions are animated alongside the lips for a cohesive full-body performance rather than a floating mouth.
- **Stable, artifact-reduced output:** The sparse-frame engine suppresses the hand, torso and facial warping that plagues many multi-talk and talking-head models, keeping the avatar solid throughout.
- **Multiple creation modes:** Upload a portrait photo, animate a still image, dub an existing clip, or hold a multi-person conversation with several characters in one video.
- **Built-in text-to-speech:** Type a script and let the built-in text-to-speech engine voice it, or upload your own recording, song or voice track as the driver.

**強み:** Infinite-length output with no hard duration cap, unusual among lip-sync tools; Full-body synchronization covers head, torso and hands, not just the mouth; Sparse-frame engine produces notably stable, artifact-light avatars; Four creation modes: photo animation, video dubbing, multi-person talk and text-to-speech

**制約・デメリット:** Credit consumption rises quickly with longer videos and higher resolutions; The most advanced batch-processing and bulk features sit behind the $199.9 Enterprise tier; No free trial is advertised, so testing requires at least the $9.9 Starter pack; Long-form renders can take a while and are handled asynchronously in the dashboard

## sync. labs (sync.so)

sync. labs (formerly sync.so) is an AI lip sync and visual dubbing platform that retimes an actor's mouth and facial performance to any audio track. It pairs a browser-based Studio with an AI Assistant, NLE plugins for Premiere Pro and DaVinci Resolve, a ComfyUI node and a REST API, so teams can localize a performance into 29 languages while keeping the original delivery intact.

**料金とプラン:** Usage-based pricing on top of a subscription. Verified plans from the pricing page: Hobbyist $5/mo (1 min videos, 3 concurrent jobs, 3 voice clones), Creator $19/mo (5 min, 10 concurrent, 5 voice clones, active speaker detection, no watermark), Growth $49/mo (10 min, 20 concurrent, 15 voice clones, 5% usage discount, 3 seats), Scale $249/mo (30 min, 50 concurrent, 50 voice clones, 20% usage discount, 5 seats, batch API). Generation is metered per frame — for example lipsync-2 at $0.002/frame (~$0.05 per second at 25 FPS) up to sync-3 at $0.00533/frame (~$0.133 per second) — while dubbing is about $0.10 per second of audio ($6/min) and text-to-speech about $0.004 per second ($0.24/min) on the entry tiers. Enterprise pricing is by contact for customization, dedicated support and negotiated rates.

- **Advanced lip sync models:** A model lineup spanning sync-3, lipsync-2-pro, lipsync-2 and react-1, handling side faces, occluded mouths, multiple faces per frame, low light and fast camera movement, up to 4K ProRes footage.
- **Visual dubbing in 29 languages:** Keep the original performance and delivery while replacing the dialogue language, so a single shoot can serve global markets without reshooting the actor.
- **Text-to-speech and voice cloning:** Generate the new voice track inside the platform or bring your own TTS API key; plan tiers include a set number of custom cloned voices.
- **Studio timeline plus AI Assistant:** A frame-accurate editor for cut, trim and split work, alongside a guided assistant where you describe the change you want and it configures the generation.
- **Pipeline integrations and API:** Premiere Pro plugin, DaVinci Resolve plugin, ComfyUI node, REST API and SDKs, with a Batch API for launching hundreds of videos in one call.
- **Watermark verification:** Proprietary watermarking lets you upload a video and check whether it was modified using sync.'s technology, supporting provenance and rights checks.

**強み:** Handles production-grade edge cases other lip sync tools struggle with: side profiles, occluded faces, multiple faces, low light and fast motion; Multiple access paths — web Studio, AI Assistant, Premiere Pro and DaVinci Resolve plugins, ComfyUI node and full API — so it fits existing pipelines; Very wide language coverage for dubbing (29 languages) paired with in-platform voice cloning or bring-your-own TTS; Fine-grained, consumption-based metering means you are billed for what you actually generate rather than buying opaque credit bundles

**制約・デメリット:** Costs stack up: a plan fee plus per-frame, per-second dubbing and per-second TTS charges can be hard to predict for high-volume projects; Entry-level Hobbyist tier is limited to 1-minute videos and 3 concurrent jobs, which is tight for real production work; Cheapest rates only unlock on the Scale plan, so heavy users on lower tiers pay noticeably more per frame; Voice cloning quotas are plan-gated (3 to 50 voices), which can constrain multi-language casting at lower tiers
