Three sound effect models behind one upload box
The Add Sound Effect form lets you switch between three models. They differ in what they require from you, what extra input they accept and how many credits they list.
| Model | What you give it | Limits shown on the form | Listed credits |
|---|---|---|---|
| mmaudio-v2 | A video and a sound description, both required | No length rule listed in its settings | See cost in the tool |
| mirelo-sfx-v1.5-v2v | A video is required; the sound description is optional, so you can let the model decide from the picture alone | No length rule listed in its settings | See cost in the tool |
| Seedance 2.0 | A video, a description up to 10,000 characters, and an optional reference audio clip | Video 3 to 15 seconds; reference audio at least 2 seconds and 15 seconds in total | See cost in the tool |

Ways to add sound effects to video across six clip types
Each still below comes from a type of clip people often need when they add sound effects to video. The line under it is the kind of description you could give the generator for that clip.
Impacts and hits
Fight scenes, sports and gameplay. Try: "heavy thud of a shin on a leather bag, chain rattling, gym echo".
Nature ambience
Travel reels and b-roll that feel empty without a bed of sound. Try: "steady waterfall roar, birds in the trees, light wind".
Close-up foley
Cooking, product and ASMR-style shots where small sounds carry the clip. Try: "crisp apple crunch, knife tapping the board".
Weather
Landscape and establishing shots. Try: "rolling thunder after the flash, wind through wheat, first raindrops".
Animation and explainers
Motion graphics and cartoon shots that start out silent. Try: "soft paper whoosh, light swish on each turn, playful tone".
Timing-heavy action
Chain reactions, tabletop shots and anything with many small events in a row. Try: "rapid wooden clicks of falling dominoes, a metal ball rolling".
How to add sound effects to video on VEME
Open Add Sound Effect and pick a model
Choose mmaudio-v2, mirelo-sfx-v1.5-v2v or Seedance 2.0 from the model menu. Each model asks for slightly different inputs, as listed in the table above.
Upload your clip
Click or drag a video into the upload area, or choose one from your History. For Seedance 2.0, keep the clip between 3 and 15 seconds.
Describe the sound
Type what should be heard in the Sound description box. On mmaudio-v2 this is required. On the other two models you can leave it empty and let the AI sound effect generator work from the picture.
Generate and review
Check the credit cost on the Add Sound Effect button, then run it. Play the result with headphones and try a new description if a cue lands in the wrong place.
Writing a sound description the AI sound effect generator can follow
The model already sees your video. Your words work best when they name sounds the picture can't make obvious on its own.
- Name the source and the material: "wooden door creak", not just "door".
- Mention the space, like "small tiled bathroom" or "open field", so the sound has the right echo.
- List the main sound first and background sounds after it.
- Keep the clip trimmed to the moment that needs sound.
- Asking for speech or dialogue; use a voice tool for that.
- Describing sounds for things that never appear or move on screen.
- Very long clips with many unrelated scenes in one run.
- Expecting a specific copyrighted song or a brand's audio logo.
AI sound effects vs a stock library vs recording foley
| AI sound effect generator | Stock SFX library | Recording your own foley | |
|---|---|---|---|
| Starting point | Your video and a short description | Searching files by keyword | Props, a microphone and a quiet room |
| Sync to the picture | Generated from the clip itself, then you review it | You line up every sound by hand in an editor | You perform or edit it to the picture |
| When it fits best | Short clips, drafts, social videos and quick tests of an idea | Projects that need one exact, well-known sound | Film and ad work where every detail must be controlled |
Many editors mix these: generate a first pass with AI, then swap in a library sound or a recorded one where a cue needs more control.
Add sound effects to video FAQ
Can I add sound effects to video for free on VEME?
Generation uses credits. Sign in and check the cost shown in the tool before running it; account offers and plan details are shown on the pricing page.
Do I have to describe the sound?
Only on mmaudio-v2, where the Sound description field is required. mirelo-sfx-v1.5-v2v and Seedance 2.0 accept a video alone, so you can try a run without any text and add a description if the result misses a sound you wanted.
How long can my video be?
Seedance 2.0 takes clips from 3 to 15 seconds. VEME doesn't list a length rule for the other two models, but short clips focused on one action are easier to review and redo.
Can I give it a sound to imitate?
Yes, with Seedance 2.0. It has an optional Reference Audio field for a clip of at least 2 seconds, and the reference audio can add up to 15 seconds in total. The other two models work from the video and your description only.
Can it add voices or music?
This tool is built for sound effects and ambience, not speech. For a narrated track, try the AI audio generator instead, then combine it with your effects in an editor.
Will every sound land exactly on the right frame?
Not always. When you add sound effects to video, the models generate audio from what they see, so fast or crowded scenes can come out slightly off. Play the result back, trim the clip to the key moment, or rewrite the description and run it again.
