Sync
A tool that automatically makes a person's lips match new audio in a video — useful for dubbing a film into another language or fixing dialogue — without needing to reshoot anything.

Description
Dubbing a video into another language, or fixing a line of dialogue after filming, traditionally means either reshooting the scene or living with lips that visibly don't match the words being spoken. Sync is a tool that fixes this automatically: upload a video and new audio (or generate the audio with text-to-speech or a cloned voice), and it regenerates the mouth movements to match, frame by frame.
Sync is aimed at professional production studios, advertising teams, and developers who need to embed lipsync into a larger pipeline. It works on live-action footage, animated characters, and AI-generated video, handling challenging conditions like low light and fast movement, and it supports translation-adjacent workflows across English, Spanish, Hindi, French, German, and Korean. Access comes via a REST API, a web studio for manual work, and plugins for Adobe Premiere and ComfyUI, so it can slot into an existing editing workflow rather than requiring a separate standalone app. Output goes up to 4K ProRes quality, and it includes proprietary watermarking to verify AI-generated or -modified footage. Pricing is usage-based per second of output video, layered under monthly plans from Hobbyist ($5/month, $0.05/sec) up to Scale ($249/month, $0.04/sec with a 20% discount), plus custom Enterprise.
💬 Our review
The short version: Sync is a professional-grade tool built for production pipelines, not casual creators, and its API-first design with Premiere and ComfyUI integration is the real differentiator versus consumer-facing competitors like HeyGen or D-ID.
Against HeyGen and D-ID, which lean more toward marketing videos and avatar-style content, Sync's positioning toward film and advertising production — with multi-face support, challenging-lighting handling, and native editor plugins — makes it a better fit for teams doing real post-production work rather than quick social clips. Against its most direct competitor, SyncLabs (a similarly-named, similarly-focused product), the comparison likely comes down to output quality and API reliability on your specific footage, which is worth testing on both before committing. The usage-based-per-second pricing on top of a monthly plan is worth doing the math on: at heavy usage, per-second costs can add up faster than a flat-rate competitor, though the discount at the Scale tier partially offsets that. For a hobbyist wanting to dub a single video, the $5/month Hobbyist tier is a low-risk way to test quality before scaling up.
