1. Prepare the required equipment: smart phone or video camera.

2. Put the equipment in a proper position stably. Use a tripod or other stable bracket to ensure that the picture is stable and will not shake.

3. Start recording: Start singing a song first. You can choose your favorite songs or nice songs to ensure that you sing accurately and emotionally.

4. Simulate the clap scene during recording. You can invite friends or family members to participate, or you can use special sound effects to simulate the sound of artificial applause.

5. After recording, you can use video editing software for post-production. Adjust the brightness, contrast and color saturation of the video to ensure a clear and bright picture.

6. Import the clapping sound effect and synthesize it with the singing video. Ensure that the sound effects are synchronized with the picture and the rhythm is consistent.
