WHAT TO EXPECT
A preview answers the useful question.
NoiseVanish cleans the audio in a supported MP4 and copies its original picture stream into the full-file result. A preview checks a selected audio segment against the original video; the full video is processed separately with account minutes.
Keep the picture
Full-file processing replaces the audio while copying supported video packets. The audio is encoded again; check playback and synchronization in the downloaded file.
A container is only the start
An MP4 extension does not guarantee a supported video or audio codec. Files need a readable audio track, compatible codecs and enough device storage. Unsupported files are refused before paid authorization when detected.
A REPRESENTATIVE COMPARISON
Hear the same moment.
This existing public-source MP4 comparison shows one recording, with its original picture preserved. It is not a guarantee for every codec or noise source.

Three steps to a result you can judge.
Choose the MP4 and a scene with both speech and noise.
Compare Original and Cleaned. Check Natural first if stronger cleanup changes the voice.
Use account minutes for the full video, then review the beginning, middle and end before publishing.
Check lip sync and transitions, not just the opening. Keep your original; a cleaned soundtrack cannot restore clipped speech, missing words or an unreadable audio track.
Supported formats and file limits
MP3, WAV, M4A, MP4, MOV and WEBM. A supported extension still needs readable media tracks and compatible codecs.
Free preview sources: up to 10 minutes / 200 MB. Paid desktop files: up to 60 minutes / 1 GB; phones and tablets: up to 30 minutes / 500 MB. Available memory, codecs and storage can lower the practical limit.
Questions about this recording
Will I download a video or just its sound?
A successful full-video task offers the cleaned video. You can also export its cleaned audio separately. A free preview is for listening, not an entitled full-video download.
Does this rebuild every video frame?
The supported video workflow copies the picture stream and replaces the audio. If the source cannot be copied or decoded safely, processing may be refused rather than silently changing the picture.
Can I remove music or another person speaking?
This workflow reduces noise around recorded speech. It does not offer separate music, speaker or background-voice stems.
