Frequently asked questions

How do you sync audio to video without a clap board?

Nomono’s sync engine analyses the audio fingerprint shared between your camera’s built-in mic and the recording of your choice. It identifies the matching waveform pattern to calculate the precise offset, then replaces the camera audio with the studio-quality Nomono track — no clap, no timecode, no manual adjustment needed.

What video formats does the Audio/Video Sync feature support?

The feature accepts MP4, MOV, MKV, WebM, OGG, and MPEG-TS video files. The output file keeps the same container, resolution, and codec as your original — only the audio track is replaced with the Nomono recording or audio recording of your choice (supported audio formats: WAV, MP3, AIFF, FLAC, OPUS, and OGG).

Is there a recording length limit for syncing?

No, there isn’t. Drift correction is applied automatically throughout, keeping the tracks locked frame-accurately even across long sessions where clock rates between devices can diverge. It works best for recordings under 2 hours.

Can I sync audio with video online without software?

Yes. Nomono runs entirely in the browser (desktop or mobile), so you can sync audio with video online without downloading software, plugins, or editing tools.

Is Audio/Video Sync free to use?

Yes. Nomono includes free audio video sync online for all Studio Cloud users. There’s no extra purchase, no software installation, and no credit card required to get started.

How do I replace audio in a video with better sound?

Upload your video and Nomono recording to Studio Cloud, and the platform automatically replaces the original camera audio with your synced Nomono track while keeping the original video quality intact.
