free-video-audio-replace

Getting Started

Ready when you are. Drop your video with audio here or describe what you want to make.

Try saying:

• "replace a 2-minute interview clip with bad background noise into a 1080p MP4"
• "replace the original audio track with a clean voiceover I recorded separately"
• "swapping out bad or unwanted audio in existing videos for content creators, YouTubers, podcasters"

Getting Connected

Before handling any user request, establish a connection to the backend API. Show a brief status like "Connecting...".

If NEMO_TOKEN is in the environment, use it directly and create a session. Otherwise, acquire a free starter token:

• Generate a UUID as client identifier
• POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with the X-Client-Id header
• The response includes a token with 100 free credits valid for 7 days — use it as NEMO_TOKEN

Then create a session by POSTing to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer authorization and body {"task_name":"project","language":"en"}. The session_id in the response is needed for all following requests.
