Use cases
Update the line you actually need to change
These focused guides cover the Video Lip Sync workflow in depth. Character swap and pet videos have their own entry points above.
Use caseChange words in a video
Got one outdated number, name, date, or sentence in an otherwise good recording? Type the corrected line, upload it, or record it — then match the mouth to it.
See the guide
Use caseUpdate a product demo video
When a launch date, product name, or offer changes after filming, a new line you type, upload, or record can keep a usable presenter segment from becoming outdated.
See the guide
Use caseReplace a video voiceover
UseLipSync starts with an existing talking video, then lets you supply new speech by typing with a selected or cloned voice, uploading audio, or recording it to appear spoken on camera.
See the guide
Use caseLip sync an AI presenter video
If you already have a clean, single-speaker AI presenter video, give it new speech by typing with a selected or cloned voice, uploading authorized audio, or recording it. UseLipSync does not create the presenter itself.
See the guideThe presenters in these examples are AI-generated. The guides show lip matching, not avatar creation.

Questions
Questions before you create
What can I create with UseLipSync?
Use Video Lip Sync to match a single-speaker video to replacement audio. Use AI Pet Podcast to animate one clear pet photo. Use Recreate to cast an authorized character in a 3–15 second reference performance.
What do the 500 starter credits cover?
They cover about two 8-second Video Lip Sync previews, or five AI Pet Podcast scene images. Talking pet video is billed at 500 credits per generated second, up to 4,000 credits for 8 seconds, so it is not included in the starter balance. Recreate also requires additional credits.
Do I need an account?
You can start Video Lip Sync and create Pet Podcast studio scenes as a guest. Sign in with Google before submitting a final Pet Podcast video or buying credits. Signed-in finished outputs stay in your Library for 30 days and can be saved for longer.
How long are my files kept?
Raw photos, video, audio, text, and voice samples expire after 24 hours. Guest results also expire after 24 hours. Signed-in finished outputs stay for 30 days; saved creations and pet scenes remain until you delete them or reach the current storage limits.
Can I use someone else’s face or voice?
Only when you have the necessary rights and permission. UseLipSync does not support unauthorized impersonation, public-figure templates, or content involving minors.
