For the zombie love story, Seedance 2.0 Mini (our Standard model) is enough for most TikTok posts: 10 credits for a 12-second 720p clip. Pick Seedance 2.0 (Pro) or 2.5 (Ultra) only if you need 1080p, at 50 and 93 credits for 12 seconds. All four models take two reference photos and generate the soundtrack with the picture.

Video: [Zombie love story (12 seconds)](https://zombie-aivideo.org/samples/love-story.mp4) (12s, 9:16). Made with the Standard model (Seedance 2.0 Mini) at 720p, 12 seconds, 9:16. The copy on this page is compressed to 496×864 for fast loading.

## The four models, side by side

Credits are for a 12-second clip. Other lengths scale in proportion and round up to a whole credit, and every format (9:16, 16:9, 1:1) costs the same.

Credits per 12-second zombie video by model and resolution

| Our name | Model | 480p | 720p | 1080p | Max resolution | Speed tier | Best for |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Standard | Seedance 2.0 Mini | 5 | 10 | Not offered | 720p | Standard queue | Most posts. TikTok compresses to about 720p anyway. |
| Fast | Seedance 2.0 Fast | 8 | 17 | Not offered | 720p | Faster variant of Seedance 2.0 | When you want the clip sooner and 720p is enough. |
| Pro | Seedance 2.0 | 10 | 20 | 50 | 1080p | Full Seedance 2.0 | Wide 16:9 or 1080p for YouTube or a big screen. |
| Ultra | Seedance 2.5 | 17 | 37 | 93 | 1080p | Newest, heaviest model | The best-looking 1080p version, or a hard pair of photos. |

For scale: 10 credits is one standard video, which costs $6.99 in the smallest pack and $2.83 in the Crew Pack. Live render times per model, from our own logs, are on the [stats page](https://zombie-aivideo.org/zombie-love-story-stats).

## Which model for which video

- **Posting to TikTok, Reels or Shorts:** Standard at 720p. The apps re-encode uploads, so the jump to 1080p is hard to see on a phone. 10 credits for 12 seconds.
- **Testing photos cheaply:** Standard at 480p, 5 credits for 12 seconds or 3 for 5. Good for checking that a face holds before you spend more.
- **A sharper vertical clip:** Fast at 720p, 17 credits.
- **YouTube, a wedding slideshow or a TV:** Pro at 1080p in 16:9, 50 credits.
- **The best version you can get:** Ultra (Seedance 2.5) at 1080p, 93 credits. Worth it for a one-off gift, not for testing.

> We publish one sample per scene, all made on the Standard model, and no side-by-side renders of the same photos across models. Choose by resolution and budget; the scene prompt is identical on every model.

## What stays the same on every model

- The same scene prompt and beat timings (see the [full prompt](https://zombie-aivideo.org/zombie-love-story-prompt)).
- Two reference photos: the survivor and the one who turns.
- An original instrumental soundtrack generated with the video. No dialogue.
- Lengths 5–15 seconds and formats 9:16 / 16:9 / 1:1.
- Automatic moderation of photos and output, and automatic refunds for failed renders.
- No watermark.

## Seedance vs other video models for this trend

The trend needs three things: two faces that stay recognizable, a hard cut between two very different settings, and sound. Seedance accepts multiple reference images and generates audio together with the picture, which is why we built on it. Other models (Kling, Veo, Runway, Pika and others) can make the trend too; how well depends on how many reference photos they accept and whether they generate sound. We have not run our prompt on them, so we do not rank them.

## Resolution, format and length

Model is only one of four choices, and the other three change the result as much. Resolution sets sharpness and cost; format sets where the clip fits; length sets how much of the story you get.

- **480p** is a preview. Faces are recognizable but soft. Use it to check a pair of photos before a final render.
- **720p** is the default and the right choice for phones. It is the highest resolution the Standard and Fast models offer.
- **1080p** is for big screens. Only Pro (Seedance 2.0) and Ultra (Seedance 2.5) offer it, and it costs roughly two and a half times as much as 720p on the same model.
- **9:16** for TikTok, Reels and Shorts; **16:9** for YouTube and TVs; **1:1** for feeds. All three cost the same.
- **12 seconds** fits the whole love story. Shorter clips skip the sunset; **15 seconds** gives every beat a little more room and costs 15/12 of the 12-second price, rounded up to a whole credit.
