How It Works

This node combines multiple media elements to create a polished TikTok-style video. It takes your base video and overlays a voice narration track with adjustable volume, optional background music, and text captions. The audio tracks are mixed together with their respective volume levels, and the caption text is rendered over the video with TikTok-style formatting. The final output is a ready-to-post social media video.

Notes

• Voice Volume: Set voice_volume between 0.8-1.2 for clear narration. Values above 1.0 may cause distortion

• Background Audio: Keep audio_volume low (0.05-0.15) so it doesn't overpower the voice narration

• Caption Formatting: Captions are automatically formatted in TikTok style with appropriate font and positioning

• Video Duration: Best results with videos between 15-60 seconds, matching typical TikTok content length

• Audio Quality: Use high-quality audio files for best results. Low-quality audio may sound distorted after mixing

• Media Compatibility: Ensure video and audio files are compatible formats and not corrupted

• Processing Time: Rendering typically takes 30 seconds to 2 minutes depending on video length and quality
