Add Music to Video — AI Background Music and Audio for Video Editing. Silent footage kills the mood. Add Music to Video lets you describe the vibe — 'upbeat background for a travel montage' or 'soft piano for a wedding clip' — and the AI picks from NemoVideo's licensed music library to match. Upload your video, specify the energy or genre you want, and get back a version with music mixed and synced. Control fade-in/fade-out timing, adjust volume balance between original audio and new track, and replace existing background audio entirely. Works for social media content, YouTube intros, wedding highlights, product demos, and any footage that needs an emotional lift. The AI handles beat matching and volume normalization so the music feels intentional, not pasted. Combine with subtitle generation or color grading in the same session. Export as MP4. Supports mp4, mov, avi, webm, mkv, mp3, wav, m4a. Works by connecting to the NemoVideo AI backend at mega-api-prod.nemovideo.ai. Supports MP4, MOV, AVI, WebM.
