AI Story Video Generator:
Which Model for Narrated Stories?

Topview T1 is the cheaper model to make story videos on: $0.22 a second at 1080p on topview.ai, against $0.585 a second for Seedance 2.5 at its official API price. Topview, an AI video and ads platform, launched T1 as its own model, built to rival Seedance 2.5 at 62% lower cost. A story channel spends most of its money on retakes of shots where a character drifted, so the cheaper second buys more chances to get them right.

The 62% compares T1 with Seedance's official API price. On Topview's own credit table, T1 uses 41% fewer credits than Topview's Seedance 2.5 rate at 1080p, 8.8 against 14.8 credits per 4 seconds. Topview's developer API lists T1 at $0.1649 a second at 720p, 28.66% off Seedance's official price, so which discount you get depends on where you run it.

The quality evidence is the launch-week side-by-sides, same prompt on both models. They come from Topview's launch campaign and several are marked as paid promotion, so judge the footage. In the story scenes, faces, costumes and light hold up about as well on T1; fast fights stay crisper on Seedance 2.5.

Write and record the narration first, then make one shot per beat of it. Treat it as working advice from our own prompting rather than a benchmark.

1. Write the story to its running time. About one beat, a moment where the picture should change, every five to eight seconds.
2. Record or generate the voice. The narration's timing decides every shot's length, so it comes before any video.
3. Split the audio at each beat and note each beat's length. a request on either model can run to 30 seconds, so one beat is always one generation.
4. Write each shot as what the viewer sees during that line, not the line itself. The narrator says she knew he was lying; the shot is her looking at his hands.
5. Decide about sound. Ambient sound under a narrator helps; dialogue generated with the picture competes with the voice. Ask for ambience only, or turn the model's audio off where you can.
6. Generate, review against the voice, retake. A shot is right when it lands on its line, not when it looks good alone.

Treat each character as a fixed asset: same image, same words, same clothes, every shot. Each generation starts fresh and knows your character only from what you send.

• One approved still per character. Generate it once, approve it, and reuse it. On topview.ai, T1's launch film lists up to 50 multimodal inputs per request, enough for a reference pack per character in a scene.
• The description, copied word for word. Mara, early thirties, short black hair, round glasses, mustard raincoat in every prompt she appears in. Paraphrasing invites a new face.
• One outfit per story. Change clothes only between episodes, never between shots.
• Chain the shots. Where a model takes a start frame instead of references, take the last frame of one shot and use it as the start frame of the next. The character walks into the new shot already looking like herself.
• Fewer people per frame. Two characters in a shot is harder than one; three is harder still. Narration lets you cut between singles.
• Budget for retakes. We price stories at 3 takes per shot below, one more than for one-off clips, because consistency is what gets shots rejected.

Make each version in the shape it will be watched in. Shorts, TikTok and Reels are vertical, 9:16; long-form YouTube is horizontal, 16:9. A story that runs on both is two edits, and ideally two sets of generations.

• Don't crop wide to tall. Cutting a vertical frame out of a horizontal one throws away most of the picture and usually a character with it. Generate vertical shots as vertical.
• Compose vertical for one subject. A tall frame fits one person well and two people badly. Favor singles, faces and over-the-shoulder shots; save wide shots for places.
• Use horizontal for space. A long-form story can afford wide establishing shots, two characters side by side and slow pans across a room.
• The price does not change. Topview's list price is per output second at any aspect ratio, so a vertical second costs the same as a horizontal one.

In these clips both models keep a lead character's face, hair and costume from the first shot to the last, which is what a story needs.

The school scene is a complete short story in one clip: girls in white uniforms crowd a student at her desk, the camera pushes into her face, and she fights back across the classroom before a final close-up. Both versions keep her long black hair, her face and her name badge through every cut. The flying kick in the middle is where Seedance 2.5 looks crisper; the quiet close-ups either side, the shots a narrator would talk over, look much the same.

The anime clip was made from the same reference image and prompt on both models. The silver-haired fighter keeps her hair, green-and-gold outfit and scythe on both, which is the reference doing its job. It is also a reminder that a vertical post is not a vertical frame: both renders inside it are landscape.

Everything the narrator talks over on T1; action climaxes on Seedance 2.5 when T1 misses.

A 60-second story a day for 30 days at 1080p, with 3 takes per shot, is 5,400 seconds of generation: $1,188 on Topview T1 or $3,159 on Seedance 2.5 at its official API price.

That saving assumes every shot stays on T1, so treat it as a ceiling. A mixed month: if the 15-second climax of each daily story goes to Seedance 2.5, the month costs $1,680.75, made of $891.00 for the other 45 seconds of each story on T1 and $789.75 for the climaxes on Seedance 2.5, both at 3 takes. That is about 47% less than all-Seedance, not 62%.

One line of narration per shot, with the character line repeated in every prompt. An original example, vertical, about a minute:

Story: The Lighthouse Cat (vertical 9:16, cold dawn light, muted film look)
Cast: Ada, old lighthouse keeper, gray braid, navy wool coat (still A)
      Pip, small ginger cat with a white chest (still B)
Shot 1, 0:00-0:08: VO: Every morning, Ada climbed the stairs to put out the light. Picture: Ada on the spiral stairs, from below. T1.
Shot 2, 0:08-0:16: VO: And every morning, Pip was already at the top. Picture: Pip sitting by the lamp, waiting. T1, start frame = last frame of shot 1.
Shot 3, 0:16-0:28: VO: One morning, he wasn't. Picture: Ada at the top, empty gallery, wind in her braid. T1.
Shot 4, 0:28-0:43: VO: She found him on the rocks, guarding a boy who had washed ashore. Picture: Ada running down the rocky path. Seedance 2.5 if T1 blurs the run.
Shot 5, 0:43-1:00: VO: Pip had kept the light that night. Picture: Ada, the boy and Pip in the doorway, sunrise. T1.

Write each shot as its own prompt, keep the cast lines and the light word for word, and generate in 9:16 from the start.

The head-to-head on price and quality is Topview T1 vs Seedance 2.5. Stories told as dialogue rather than narration are covered in the AI short drama guide, anime-styled stories in the AI anime video guide, and running a story channel week to week in AI video for faceless YouTube.

The free Topview T1 skill plans the shots, prices each one on T1 and Seedance 2.5, and drafts them on T1 from your coding agent. For a story told over many episodes, the premium AI short drama series skill starts from a series bible and saved characters, then makes the episodes scene by scene.

T1 also runs inside AdAnt, the AI social media marketing team we build: select Topview T1 in Studio's video picker, or ask the Creator for it by name. Per second it uses 60% fewer credits than Seedance 2.5 at 1080p and 54% fewer at 720p. There it starts from a prompt, or from a start frame with an optional end frame, and takes no reference images, which suits chaining each shot from the last frame of the one before; when you start from a frame, the clip follows that frame's shape, so a vertical start frame gives a vertical shot.
