Why Pick Seedance 1.5 Pro on Yovid

Sound Rendered in the Same Pass

Before December 2025 every Seedance clip was silent, and a voice or a door slam had to be laid in later. Seedance 1.5 Pro was the release that changed that: it renders the audio track together with the frames, so a footstep or a spoken line lands where the motion is.

Sound is switched on when you open the composer. Turn it off for a clip you plan to score yourself; the credit charge does not change either way. Describe what should be heard near the end of the prompt, and put any spoken words in quotation marks.

Price with soundUnchangedA clip costs the same credits with or without audio.

Free Credits Cover It, Without a Watermark

Seedance 1.5 Pro sits in Yovid’s entry tier, which means the credits a new account receives at sign-up can be spent on it straight away, no card required. Free and Lite accounts can pick 480p or 720p; 1080p opens up on Pro, on Premium, or with any one-time credit pack.

Free-plan videos are saved without a watermark, so a draft you like can go straight into an edit.

The Lowest Rate of Any Seedance With Sound

Among the Seedance versions on Yovid that produce audio, 1.5 Pro charges the fewest credits per second at every resolution it shares with them: a 5-second 480p take is 3 credits and a full 12-second 720p clip is 14. Only the silent Seedance 1 Pro Fast costs less.

That makes it the practical place to rehearse an idea. Run a handful of short 480p versions, keep the wording that works, and render the final one here at 1080p or carry the prompt over to Seedance 2.0 or 2.5.

Animate a Photo, or Pin Both Ends of the Shot

A first frame fixes the look of the opening second: the subject, the light, the framing. Add a second picture as the last frame and the model also has to arrive somewhere, which is how you get a controlled reveal, a day-to-night change or a product turning to face the camera.

Every resolution stays available when you start from a picture, including 1080p on plans that allow it, and the frames add nothing to the credit charge. 1.5 Pro does not take reference images or reference clips; for a face, outfit or product that must carry over from several photos, use Seedance 2.0 Mini or 2.0.

Pick the frame shape before writing, so the action is composed for it: 9:16 for phone feeds, 21:9 for a letterbox look, 4:3 or 3:4 for something closer to a print. Adaptive lets the model choose the shape from the prompt or your first frame. The composer opens on 16:9, 480p and 5 seconds.

Who Gets the Most from Seedance 1.5 Pro

Short clips with sound at a price low enough to try things suit these people best:

  • Prompt writers: Several cheap 480p takes of the same idea, so the wording is settled before credits go into a longer or sharper render.
  • Creators on the free plan: Vertical 9:16 clips with a voice or ambience for Reels, Shorts and TikTok, without paying for a plan first.
  • Small shops: A product photo as the first frame, turned into a short moving shot with room sound.
  • Storyboard and animatic makers: A first and a last frame from the board, with the in-between move rendered up to 12 seconds.
  • Teachers and explainers: A short scene with a line of narration to open a lesson or a slide deck.

Seedance 1.5 Pro vs 2.0 Mini, 1 Pro Fast, 2.0 Fast and 2.5

Every row except “Best for” is read from the settings each model offers in Yovid’s generator today, so the lengths, limits and credits match what the composer will charge.

Seedance 1.5 Pro: Strengths and Limits

What it does well for the price, and when a newer Seedance is worth the extra credits.

Strengths

  • Price: The fewest credits per second of any Seedance with audio on Yovid.
  • Free plan: Runs on sign-up credits at 480p or 720p, with clean downloads.
  • Sound included: Dialogue, effects and music rendered with the picture, at the same price as a silent clip.
  • 1080p from a frame: Starting from a photo keeps every resolution, unlike Seedance 2.0 Fast.

Limits

  • No references: No reference images or clips, so a character cannot be pinned from several photos.
  • Length: 12 seconds per clip; the 2.0 models reach 15 and Seedance 2.5 reaches 30.
  • No edit or extend: Changing or continuing an existing video is a Seedance 2.5 feature on Yovid.
  • Older model: Two releases behind Seedance 2.5; use 2.0 or 2.5 for multi-shot scenes and characters held by reference images.

Seedance 1.5 Pro Starter Prompts

Prompts we wrote for 1.5 Pro, each with the sound spelled out. The first is written for a shot like ByteDance’s jazz-bar clip, not its original prompt; the other cards have no sample clip yet. Attach your own picture before running the frame prompts.

  • Late set at the jazz bar

    Text to video · 8 s

    A smoky jazz bar late at night, warm bulbs out of focus behind the stage. A singer with long curly hair in a dark velvet dress holds a vintage chrome microphone and sings a slow ballad with her eyes half closed. The camera drifts in from a medium shot to a close-up of her face. Sound: her voice, a soft upright bass and brushed drums, glasses clinking at the tables.

  • Ramen stall in the rain

    Ramen stall in the rain

    Text to video · 10 s

    Night, a narrow street ramen stall under a red paper lantern while light rain falls. The cook lifts noodles from a steaming pot and lets them drop into a bowl, then slides it across the counter to a customer in a wet raincoat. Static side angle at counter height. Sound: rain on the canvas awning, boiling water, the cook saying “Here you go, careful, it’s hot.”

  • Bring a product photo to life

    Bring a product photo to life

    First frame · 6 s

    Use the attached photo as the first frame. The product stays centred and sharp while the camera makes a slow half orbit to the right and soft morning light slides across its surface. Nothing else in the frame changes. Sound: quiet room tone and one gentle chime at the end.

  • From dusk to lights on

    From dusk to lights on

    First + last frame · 12 s

    Start on the first frame, a quiet street of small shops at dusk, and end on the last frame, the same street after dark with every window lit. Keep the camera locked off. People pass on the pavement, and the shop lights switch on one by one from left to right. Sound: evening traffic, footsteps, a bicycle bell.

FAQs

What is Seedance 1.5 Pro?

Seedance 1.5 Pro is a video model from ByteDance’s Seed team, released in December 2025. It was the first Seedance model to generate an audio track together with the video. Yovid runs it for clips of 4 to 12 seconds at 480p, 720p or 1080p, started from words alone, from one picture, or from a pair of pictures that open and close the shot.

Is Seedance 1.5 Pro free to use?

Yes. Yovid’s free plan includes it among its entry models, so the credits you get when you sign up, with no card, can be spent on it at 480p or 720p. Downloads carry no watermark. 1080p needs Pro, Premium or a one-time credit pack.

How many credits does a Seedance 1.5 Pro clip cost?

Each second costs 0.6 credits at 480p, 1.2 credits at 720p or 2.6 credits at 1080p, at credit-pack rates. A 5-second 480p clip costs 3 credits, a 12-second 720p clip 14, and a 12-second 1080p clip 31. Sound and frames add nothing, subscribers pay fewer credits per second, and the composer shows the exact figure before you generate.

Does Seedance 1.5 Pro make videos with sound?

Yes. The model writes the audio track while it renders the frames: voices, effects, room tone and music. The Sound switch starts on, and turning it off for a clip leaves the credit charge where it was.

Can I turn a photo into a video with Seedance 1.5 Pro?

Yes. Attach the photo as the first frame and describe the motion. You can also add a second picture as the last frame, and the clip will end on it. JPEG, PNG and WebP files up to 10 MB work, and every resolution stays available.

Does Seedance 1.5 Pro accept reference images or videos?

No. It takes a first frame and an optional last frame only. To keep a character or product consistent from several photos, or to copy movement from a clip, use Seedance 2.0 Mini, 2.0 Fast, 2.0 or 2.5.

Seedance 1.5 Pro or Seedance 2.0 Mini: which should I use?

Both run on the free plan and both generate sound. 1.5 Pro costs less than half as much per second at 720p and goes up to 1080p. Mini is newer, reaches 15 seconds and accepts as many as 9 reference pictures plus 3 reference clips, yet tops out at 720p.

How is Seedance 1.5 Pro different from Seedance 2.0 and 2.5?

Seedance 2.0 adds multi-shot scenes, reference images and clips, 15-second clips and output up to 4K. Seedance 2.5 goes to 30 seconds, accepts up to 30 images and 10 clips as references, and can edit or extend a video you upload. Both cost more per second and need a paid plan or a credit pack.

Can I use Seedance 1.5 Pro through the Yovid API?

Yes, with the model ID seedance-1.5-pro. It is one of the three Seedance IDs a key can call without a subscription or credit pack, with the same 4–12 second range and 2,000-character prompt limit as the composer.

Can I use Seedance 1.5 Pro videos commercially?

Commercial use comes with Pro, Premium, yearly Lite and every one-time credit pack; monthly Lite does not include it. You are responsible for the rights to the frames, faces, brands and music you put into a clip.
