How AI Long Video Works
Generate and download a finished cinematic video from five seconds to a complete minute.
From Prompt to Finished Video
02
Choose your plan and video length
Starter supports compatible short clips up to 15 seconds. Pro adds 30-second videos, Studio adds 60-second videos, and Agency adds optional 1080p. Choose from Seedance 2.0 Mini, Seedance 2.0 Standard, Kling 3.0, and Seedance 2.5 where compatible.
03
Select production settings
Choose a resolution supported by your model and plan. Mini offers silent 480p video; the other models include audio. Agency defaults to 720p with 1080p as an explicit choice. Set the format, optionally add an opening image, and review the exact credit cost in the generator.
04
Generate with frame continuity
5s, 10s, 15s, and 30s generate in one pass. For 60s, the first 30s Seedance 2.5 scene finishes before its final frame is used to start the continuation.
05
Automatic assembly
After the continuation is ready, both scenes and their native audio are joined into one finished MP4.
06
Preview and download
The finished video appears in your history as one playable, downloadable file. No editor or manual stitching is required.
Models and Durations
Your plan sets the available length and resolution. Your chosen model determines the compatible settings. Every completed video is delivered as one finished MP4.
- Starter and above: compatible short clips up to 15 seconds and 720p
- Pro and above: 30s uses 1 native Seedance 2.5 generation with audio
- Studio and Agency: 60s uses 2 connected 30s Seedance 2.5 scenes with audio
- Only Agency offers 1080p; 720p remains the default
- 60s scenes are assembled automatically into one playable, downloadable file
Model selection and credit guide
Exactly How Many Credits Does a Video Use?
These are AI Long Video website credits from your plan or top-up balance. The same model, resolution, and duration cost the same number of credits on every eligible plan. A higher plan unlocks longer videos or 1080p; it does not require you to choose a more expensive model.
For 5s or 10s, choose Mini, Standard, Kling, or Seedance 2.5 at a supported resolution. For 15s, choose Mini at 480p or Standard at 480p/720p. For 30s or 60s, choose Seedance 2.5. The table shows each available combination; a dash means that combination is not offered.
| Model / resolution | Audio | 5s | 10s | 15s | 30s | 60s |

| Seedance 2.0 Mini 480p | Silent | 250 | 500 | 750 | — | — |
| Seedance 2.0 Standard 480p | Included | 950 | 1,900 | 2,850 | — | — |
| Kling 3.0 720p | Included | 1,000 | 2,000 | — | — | — |
| Seedance 2.5 480p | Included | 1,500 | 3,000 | — | 9,000 | 18,000 |
| Seedance 2.0 Standard 720p | Included | 2,000 | 4,000 | 6,000 | — | — |
| Seedance 2.5 720p | Included | 3,000 | 6,000 | — | 18,000 | 36,000 |

5s/10s/15s: Starter and above. 30s: Pro and above. 60s: Studio and Agency. All 1080p options: Agency only, at 30s or 60s. Credits alone do not unlock a duration or resolution outside your plan. On a phone, swipe the table to see every duration.
Before you submit, the generator checks availability and shows your selected model, resolution, duration, per-video cost, total charge, current balance, and balance after generation. Review that quote before clicking Generate. If the price has changed, refresh and review it before submitting again.
What Is Included, and When Are Credits Used?
One price for the selected output
The listed charge includes the full selected duration, included audio, and final MP4 assembly. Mini is silent. A 60s price covers both 30s scenes and their assembly; it is not charged again for stitching. Prompt, negative-prompt, style, camera, and lighting selections do not add a separate credit charge. An optional approved opening image does not change the displayed generation rate.
Batch totals and balance
For 5s, 10s, and 15s clips, total credits equal the per-video rate multiplied by the number of videos. Each video has the selected duration. For example, two Mini 15s videos cost 1,500 credits in total. Generate 30s and 60s videos one at a time. If your balance is too low, the generator shows the shortfall before you can start.
Reservation and repeat submissions
Credits are reserved from your available balance when an order is accepted, before the finished video is ready. The page confirms the reserved charge and remaining balance. Retrying the same submission does not charge twice. Creating a separate new video is a new order with its own displayed credit charge.
If a video fails
If the system confirms that a video cannot be completed, its full website-credit charge is restored to your balance. For a 60s video, this covers the entire finished video, even if one scene has already completed. In a batch, successfully completed videos remain charged; each failed video is refunded separately in website credits.
If a video is retrying or paused
A temporary processing or delivery problem may continue under the same order without another website-credit charge. An order paused for review keeps its credits reserved until the review is resolved. A pending or paused status is not a confirmed failure. Check Video History before creating a separate new order.
Your finished file
Completed videos appear in Video History as playable, downloadable MP4 files, with the model and credit charge shown for each order. A 60s video uses the first scene's final frame to start the second scene, then combines them into one file. This helps continuity but does not guarantee identical motion, characters, or audio across the join.
