# Frequently Asked Questions about Lipsync ### Q: Can we process a full video while only applying lip sync to specific segments? We're trying to personalize welcome messages, changing one word {name} to the user's name. For example: "Hey {name}, thanks for signing up for our service." We only need the user's name to be lip-synced. A: We don’t offer this yet, but you can make API calls with only the {name} and stitch it with a fixed video that says "..thanks for signing up for our service.". Here is a Gooogle Colab sample to set this up with our API: {% embed url="" %} ### Q: I'm getting a message on lipsync projects about "truncated to 250 frames". What does this mean?
A: 250 frames cut-off applies to the input video you have added to the Lipsync workflow - if your video is 24 fps the output will be \~10s, at 60 fps it'll be \~4s and so on. If you use an image for the lipsync input instead of a video, the default if 25fps so thats \~10s again. There is no cut-off once [upgrade](https://gooey.ai/account/billing/) to a paid subscription! ### Q: How to clear LipSync history A: If you are using Gooey.AI API we support this via a simple “keep” or “delete” as an API/SDK request parameter: ``` "settings": { "retention_policy": "delete" } ``` If you are using the Gooey.AI web app, please fill out this form and we will action your request in 5-7 business days. ### Q: What are the rate limits for creating lipsync videos?
