What does native audio mean in AI video generation?
Native audio means the video model can generate a synchronized soundtrack as part of the video task. Everygen exposes a Seedance audio toggle, so sound is returned with the MP4 instead of requiring a separate text-to-speech or sound-effect step.
Use native audio for ambience, short dialogue, effects or a simple spoken line.
For exact voiceover timing, brand music or regulated claims, edit and verify the sound in post-production.
Which Everygen model supports audio?
Seedance 2.5 supports generated audio. Kling 3.0 Turbo does not generate audio in the current studio. Both models support text-to-video and image-to-video.
- Seedance offers 4–30 second durations and 480p, 720p or 1080p.
- Seedance supports 9:16, 16:9, 1:1, 4:3, 3:4, 21:9 and adaptive formats.
- Kling offers 4–15 second durations at 720p with 9:16, 16:9 or 1:1.
How do you prompt audio in a video generation?
Describe the sound after the visible scene and camera. Name only the audio that matters most, such as rain, footsteps, room tone, a short spoken phrase or a product impact.
Use short, explicit sound cues rather than a long list of overlapping effects.
Write spoken lines in quotation marks and keep them brief.
Review pronunciation and claims before publishing generated dialogue.
What are the limits of generated audio?
Generated audio can change pronunciation, timing or ambience between runs, and it cannot guarantee a specific branded voice or licensed track. Treat native audio as a creative draft that may need an editing pass.
- Do not expect sample-accurate lip-sync for complex dialogue.
- Avoid exact music imitation or recognizable artist voices.
- Check audio disclosure requirements on the destination platform.
- Keep important speech short enough to review in the complete clip.
How much does a video with audio cost?
Audio is generated with the Seedance task and does not add a separate Everygen credit charge. A four-second Seedance 720p clip costs 16 credits; an eight-second 1080p clip costs 35.
A 15-second 1080p Seedance clip costs 66 credits.
A 30-second 1080p Seedance clip costs 132 credits.
Kling remains lower-cost for silent clips but cannot replace Seedance when native audio is required.
What are good prompt examples?
Strong prompts describe a visible action, one location and one camera direction. Adapt the subject and product details rather than copying a prompt without checking the result.
Rain and footsteps
A lone traveler walks a wet mountain trail before sunrise, slow follow camera, visible breath and footsteps, ambient wind and distant water, one continuous cinematic shot, 16:9.
Product impact
A matte red can lands on wet black stone, crisp impact splash, short metallic thump followed by low ambient room tone, locked macro camera, dramatic rim light.
Short spoken hook
Close vertical shot of an unbranded skincare bottle in morning light, a calm voice says “Your routine, simplified,” subtle room tone, slow push-in, natural hand movement, 9:16.
Seedance audio video credit examples
Credit totals use the current Everygen studio settings and are rounded up to a whole credit for each generation.
| Duration | Resolution | Audio | Credits |
|---|---|---|---|
| 4 sec | 480p | Included | 14 |
| 4 sec | 720p | Included | 16 |
| 8 sec | 1080p | Included | 35 |
| 30 sec | 1080p | Included | 132 |
What matters most before you generate?
- Start with one clear action and one camera direction so the model has a specific motion to solve.
- Upload a clean first frame whenever product shape or a particular scene must stay consistent.
- Test a short, lower-cost generation before committing to a longer Seedance render.
- Review text, hands, product details, audio and disclosure requirements before publishing.
