Use it after the translated voice already sounds right. VoiceCheap currently offers three lip sync tiers: | Tier | Best fit | Current limit | Extra billed minutes per translated minute | | --------------- | ------------------------------------------------------------------- | ------------- | ------------------------------------------ | | Lip Sync | Fast general-purpose lip sync, especially for HD workflows | 30 minutes | 4 | | Lip Sync Pro | Higher-detail lip sync for premium output and 4K-friendly workflows | 30 minutes | 9 | | Lip Sync Studio | Highest-quality tier, smarter handling, strongest 4K positioning | 30 minutes | 14 | ## Plan availability | Plan | Available lip sync add-ons | | -------- | ------------------------------------------- | | Beginner | Lip Sync | | Creator | Lip Sync and Lip Sync Pro | | Scale | Lip Sync, Lip Sync Pro, and Lip Sync Studio | ## Which one should you choose ### Lip Sync Use `Lip Sync` when: * speed matters * the source is HD or standard production quality * you want a good balance between quality and cost ### Lip Sync Pro Use `Lip Sync Pro` when: * you want stronger detail around facial features * the content is more premium * you can afford a slower, more expensive run ### Lip Sync Studio Use `Lip Sync Studio` when: * quality matters more than speed * the project is premium and visually demanding * you are working on a shorter, high-value clip ## Why Lip Sync Studio is better than Lip Sync Pro `Lip Sync Studio` is not just a slightly improved version of `Lip Sync Pro`. It is a more advanced model tier with stronger scene understanding. In practice, that usually means: * better consistency across the whole shot * fewer visible transitions or flicker between generated moments * stronger handling of obstructions such as hands, microphones, scarves, or partial face coverage * better performance on profile shots and harder camera angles * stronger preservation of expression, cadence, and emotional delivery * better fit for premium 4K-oriented output `Lip Sync Pro` is still excellent when you want a premium result with stronger facial detail than standard lip sync. `Lip Sync Studio` is the better choice when the shot itself is difficult or when the visual standard is especially high. ## Demo videos Lip Sync Studio can handle demanding footage such as detailed close-ups, low-light scenes, emotional performances, sharp camera angles, and multiple speakers. These demos show the kinds of cases where the Studio tier is usually the best fit. ### Lip Sync Studio: keep details
