AI video with native audio
Generate a short AI video with sound in one request.
Describe the visuals and the dialogue, ambience, or effects you need alongside them. Vizify uses only a policy it has inspected for native audio, and it stops with an explanation rather than quietly returning a silent clip.

Start with the messy versionOptional choices help Vizify shape the handoff.
Try a starting point
Your brief and staged inputs open in Vizify for review before generation.
One short video with native audio
A clip you can review with sound before it reaches an edit or a feed
Any reference audio you staged stays attached to the request
What it does
Built to hand back finished work.
Audio is part of the contract
Audio support is model-specific. Vizify uses only a policy it has inspected for sound, stops with an explanation instead of substituting a silent model, and does not promise precise lip-sync.
Describe the mix, not just the shot
Separate the three audio layers — spoken words, room ambience, and specific effects — and say which of them should dominate. Sound written as an afterthought at the end of a visual brief usually comes back as generic background noise.
Listen before you look
Play the clip with sound first: check that speech matches the words you supplied, that the ambience fits the location, and that no effect lands on the wrong frame.
FAQ
Questions, answered.
What happens if no compatible model supports audio?
Vizify stops and explains the incompatibility. It does not fall back to a silent model and present that result as though the audio request had been satisfied.
Can I upload a reference audio track?
Yes — MP3, WAV, OGG, FLAC, or M4A, up to three files of 20 MB each. It guides rhythm and sound character rather than being copied into the output as a soundtrack, and uploading needs a free Vizify account.
Is lip-sync accurate?
No. Mouth movement is approximate and changes between takes, so keep dialogue short and review the clip yourself before using it anywhere speech accuracy actually matters.
Can I ask for a specific voice or accent?
You can describe one — age, tone, pace, accent — and the model will interpret it. Vizify does not clone a named person's voice, and the same description will not produce an identical voice across separate jobs.
Can I get music instead of dialogue?
You can ask for a mood or an instrumentation and some models will oblige, but this is a video capability rather than a music generator. Full compositions and licensed tracks belong in a dedicated audio workflow.
Which model gets selected here?
Only a public model whose inspected policy supports audio for the requested operation and inputs. That narrows the field, so some framing or duration combinations offered on silent video pages are not available on this one.
Is the video ready immediately?
No. Video generation runs asynchronously and takes minutes rather than seconds. Vizify keeps polling the job until it completes or fails, so you receive a finished file or a clear failure, never a pending status dressed up as a result.
Do I need a Vizify account?
You can write and refine the brief on this public page without signing in. An account is required to run the generation job, to upload files, and to keep the completed artifact in your workspace afterwards.
Keep the request to one short clip

Vizify uses only a policy it has inspected for sound, stops with an explanation instead of substituting a silent model, and does not promise precise lip-sync.
Where lip-sync stands today
Models that generate picture and speech together can place a voice convincingly, but mouth shapes stay approximate and vary between takes. Keep spoken lines short, avoid tight close-ups on the mouth when accuracy matters, and treat any dialogue-heavy result as a draft you check frame by frame before it goes anywhere.
Review the generated result
Vizify follows the asynchronous job until it completes or fails, then returns the finished artifact rather than a pending status. Play the clip with sound first: check that speech matches the words you supplied, that the ambience fits the location, and that no effect lands on the wrong frame.
