 ## What video clips to record

+You need several types of basic video clips:
 
-**Consent Video:**
+**Consent Video (Required)**
+The consent video is required for creating a custom avatar. 
    - The consent video must represent the same avatar talent speaking, following the requirement of the consent statement. Make sure the statement is correctly recorded, and each word is clearly spoken. [Get consent file from the avatar talent](custom-avatar-create.md#get-consent-file-from-the-avatar-talent). You can select any one of the languages supported. 
    - The avatar talent should always face the front of the camera, without large movements. 
    - The video should be taken in a quiet environment, and the voice should be recorded at a reasonable volume. Try to keep the signal-to-noise ratio higher than 20. For voice recording guidance, see the [Recording custom voice samples](../record-custom-voice-samples.md#recording-your-script) guide.
    - Ensure that the head part will not be occluded in each frame of the video. 
    - Make sure no other objects appear in the camera, including filming equipment, mobile phone, etc. 
 
-**Status 0 speaking:**
+**Status 0 speaking (Required for gestures)**
+The status 0 speaking video clip is required for gestures with the avatar.
    - Status 0 represents the posture you can naturally maintain most of the time while speaking. For example, arms crossed in front of the body or hanging down naturally at the sides. 
    - Maintain a front-facing pose. The actor can move slightly to show a relaxed status, like moving the head or shoulder slightly, but don't move the body too much.
    - Length: keep speaking in status 0 for 3-5 minutes.

-**Naturally speaking:**
+**Naturally speaking (Required)**
+The naturally speaking video clip is required for the avatar to speak naturally.
    - Actor speaks in status 0 but with natural hand gestures from time to time.
    - Hands should start from status 0 and return after making gestures.
    - Use natural and common gestures when speaking. Avoid meaningful gestures like pointing, applause, or thumbs up.
    - Length: Minimum 5 minutes, maximum 30 minutes in total. At least one piece of 5-minute continuous video recording is required. If recording multiple video clips, keep each clip under 10 minutes.

   - Maintain status 0, don't speak, but still feel relaxed.
   - Even remaining in status 0, don't keep still; you can move slightly but not too much. Perform like you're waiting.
   - Maintain a smile as if listening or waiting patiently.
   - Avoid nodding frequently.
   - Length: 1 minute.

+**Gestures (optional)**
 
 Gesture video clips are optional, and customers who have the need to insert certain gestures in the avatar speaking can follow this guideline to take gesture videos. Gesture insertion is only enabled for batch mode avatar; real-time avatar doesn't support gesture insertion at this point. Each custom avatar model can support no more than 10 gestures.
 
-**Gesture tips:**
+**Gesture tips**
 - Each gesture clip should be within 10 seconds.
 - Gestures should start from status 0 and end with status 0. It's essential that the character maintains the same position as in status 0, which is in the middle of the screen, throughout the gesture. Otherwise, the gesture clip can't be smoothly inserted into the avatar video. 
 - The gesture clip only captures the body gestures; the actor doesn't have to speak during making gestures.
 - We recommend designing a list of gestures before recording; here are some examples of gesture video clips:
