Correction, 2026-10-02: this page described long takes in terms we had not measured: that one generation keeps light, framing and subject consistent, that stitched clips drift, that long generations "amplify" errors, that Kling v3 is "comfortable" at 10 to 15 seconds and that Veo and Omni are "excellent models". Those lines are now checkable facts per model (length, price at full length, resolution, sound, start image) and advice. Two errors fixed: four 8-second Veo 3.1 Lite clips leave 2 seconds to trim, not 32, and one Wan 3.0 pass is not always the cheapest way to 30 seconds (at 720p, four Veo 3.1 Lite clips cost 216 credits against 284). Added: Wan 2.5 makes 5-second clips on 8frame, Pruna Avatar and OmniHuman 1.5 follow the audio up to 35 seconds, and how to join clips on 8frame (the Montage node, the Video Editor's timeline). The page also did not say that the Montage node's output has no sound: it drops the clips' own audio, so sound goes on the Video Editor timeline.
Correction, 2026-09-30: we said every model other than Wan 3.0 and Seedance 2.5 stops at 15 seconds. Pruna p-video and Creatify Boreal, added to 8frame in late September, reach 20. Added below.
The best AI video generator for long clips in 2026, judged by length and price on 8frame, is Wan 3.0: up to 30 seconds in a single pass for 142 credits at 480p on the base model, about $1.42 at pack rate, or 284 at 720p. Seedance 2.5 also reaches 30 seconds, at 937 credits for 30 seconds at 720p, about 3.3 times Wan 3.0 base at the same resolution. Pruna p-video and Creatify Boreal, both new to 8frame, reach 20 seconds for less per second (we quote their prices, not their quality). The other generators in the table top out between 8 and 15 seconds, so anything longer is built from several clips joined in an edit, and every join is a cut you have to plan.
TL;DR
- Wan 3.0 base: 2 to 30 seconds at 480p, 720p or 1080p; 24 credits for 5s and 142 for 30s at 480p. The cheapest 30-second single take on 8frame, lip-sync tools aside. The Wan node opens at 1080p (95 for 5s, 567 for 30s), so set the resolution before you render. Prime costs about twice as much at every resolution
- Seedance 2.5: 4 to 30 seconds at 480p or 720p, sound included in the price; 157 credits for 5s and 937 for 30s at 720p (417 at 480p)
- Pruna p-video and Creatify Boreal: 1 to 20 seconds; p-video is 54 credits for 20 seconds at 720p (14 on its Draft tier), Boreal 27 at 720p with sound. New to 8frame, so price only
- Kling v3 Standard: 3 to 15 seconds at 720p, needs a start image; 86 credits for 5s and 256 for 15s with sound
- Hailuo H3: 5 to 15 seconds at 2K, 88 credits for 5s, 264 for 15s
- Veo 3.1 and Gemini Omni Flash: Veo makes 4, 6 or 8 seconds (always 8 from a start image), Omni Flash 3 to 10. Short clips by design, so not the tool for a long take
- Wan 2.5: makes 5-second clips on 8frame, so it is not a long-clip option
- Talking heads: Pruna Avatar and OmniHuman 1.5 follow the audio track, up to 35 seconds
- Joining clips: the Montage node joins 2 to 10 clips for 10 credits; the Video Editor mode has a timeline
- The honest catch: one 30-second generation is one roll of the dice. If second 22 is wrong, you pay for all thirty again
The length table
Canon 8frame prices from the tool registry, a credit is $0.01 in a top-up pack. "Price at full length" is the cost of the longest clip the model makes on 8frame.
| Model | Length on 8frame | Price at full length (credits) | Resolution | Sound | Start image |
|---|---|---|---|---|---|
| Wan 3.0 base | 2 to 30s | 142 (480p), 284 (720p), 567 (1080p) for 30s | 480p, 720p, 1080p (opens at 1080p) | no sound setting | optional |
| Wan 3.0 Prime | 2 to 30s | 276 (480p), 567 (720p), 1134 (1080p) for 30s | 480p, 720p, 1080p | on by default, same price | optional |
| Seedance 2.5 | 4 to 30s | 417 (480p), 937 (720p) for 30s | 480p, 720p | toggle, same price either way | optional |
| Pruna p-video | 1 to 20s | 54 (720p), 108 (1080p) for 20s | 720p, 1080p | generated | optional, the clip takes its shape |
| Pruna p-video Draft | 1 to 20s | 14 (720p), 27 (1080p) for 20s | 720p, 1080p | not confirmed | optional |
| Creatify Boreal | 1 to 20s | 27 (720p), 81 (1080p), 324 (2K) for 20s | 720p, 1080p, 2K | always on | optional reference image |
| Kling v3 Standard | 3 to 15s | 256 with sound, 171 silent for 15s | 720p | on by default, silent is cheaper | required |
| Hailuo H3 | 5 to 15s | 264 for 15s | 2K | no sound setting | optional |
| Gemini Omni Flash | 3 to 10s | 169 for 10s | 720p | always on | optional |
| Veo 3.1 Fast (the Veo node's default) | 4, 6 or 8s | 168 with sound, 112 silent for 8s | 1080p | on by default, silent is cheaper | optional, and it locks the clip to 8s |
| Veo 3.1 Standard | 4, 6 or 8s | 448 with sound, 224 silent for 8s | 1080p | on by default, silent is cheaper | optional, locks to 8s |
| Veo 3.1 Lite | 4, 6 or 8s | 54 with sound, 33 silent for 8s | 720p | on by default, silent is cheaper | optional, locks to 8s |
Two things fall out. Length and price per second do not move together: Wan 3.0 base at 480p costs about 4.7 credits a second for up to 30 seconds, while Veo 3.1 Standard costs 56 a second and stops at 8. And Wan 2.5, still in the Wan picker, makes 5-second clips on 8frame (102 credits at 1080p), so leave it out of long-clip plans.
Long single take vs stitching
One generation gives you one continuous shot with no join to hide. It costs control: you cannot fix a bad second without redoing the whole clip, and whether light, framing and subject hold for 30 seconds is something to check in the result, not something to assume.
Stitching gives the opposite: every segment can be regenerated on its own and cheaply, at the price of a join every few seconds, where light, framing and subject have to match across clips generated separately. Use the same start image or reference for every segment, and check every join before you commit.
To join clips on 8frame, the Montage node (Merge Videos) takes 2 to 10 clips and adds transitions for 10 credits per run. It cuts each clip to a maximum length you set from 1 to 15 seconds (5 by default), so raise that setting before you merge longer clips. It joins the picture only: the merged file has no sound, so the audio of clips generated with sound (Veo, Kling, Seedance 2.5) is dropped. For a 30-second take, or to add sound and captions, use the Video Editor mode, which has a timeline with sound layers.
The cost comparison at canon prices, for 30 seconds of finished video:
- One Wan 3.0 base pass: 142 credits at 480p, 284 at 720p, no joins
- Four Veo 3.1 Lite clips at 8s with sound (720p): 216 credits for 32 seconds, three joins, 2 seconds to trim
- Two 15-second Pruna p-video clips at 720p: 82 credits, one join (price only, as above)
- Two Kling v3 Standard clips at 15s with sound: 512 credits, one join, a start image for each
- Three Gemini Omni Flash clips at 10s: 507 credits, two joins
Joining on the canvas adds 10 credits per Montage run. So the single pass is not automatically the cheapest: two p-video clips (82) and four Veo 3.1 Lite clips (216) both cost less than one Wan 3.0 pass at 720p (284). What the single pass buys is a take with no joins.
Where each one is the right call
Wan 3.0 for anything where the shot should feel like one take: a slow product reveal, an atmospheric establishing sequence, a long push through a space. Use the base model; Prime costs about twice as much at every resolution. Correction, 2026-09-28: this page previously recommended Prime at a flat 203 credits for 30 seconds. Prime is resolution-tiered and was repriced on 2026-09-05; base is the cheaper long take. Base Wan 3.0 has no sound setting on 8frame: if the take needs sound, Prime generates audio by default at no extra charge, or you add a sound layer in the Video Editor.
Seedance 2.5 when the 30-second take needs sound generated with it, or reference images, and the budget covers 937 credits at 720p (417 at 480p).
Kling v3 when 15 seconds is enough and you already have the opening frame: it needs a start image, renders 720p and costs 256 credits for 15 seconds with sound, 171 silent. Silent 5-second clips are 57 credits.
Hailuo H3 when the clip has to be 2K: 264 credits for 15 seconds.
Pruna Avatar or OmniHuman 1.5 for a talking head up to 35 seconds: both turn a portrait and an audio track into a clip as long as the audio. Pruna Avatar is 119 credits for 35 seconds at 720p (213 at 1080p), OmniHuman 1.5 is 784. They animate a person speaking, they do not generate a scene; see lip-sync prices by model.
Stitching short clips whenever the sequence is genuinely several shots. A 30-second ad with six distinct setups is not a long-clip problem, it is a shot list. Length in one pass is for one continuous shot, not for a whole edit.
The risk with long takes
A long generation is paid for in full before you see it. If one moment is wrong (a hand, a reflection, a product label), you cannot fix that second on its own: you regenerate the whole take. A failed generation is refunded automatically; a finished one you do not like is not.
The workflow that handles this: draft the shot short and cheap first. Generate 5 seconds on Wan 3.0 base at 480p for 24 credits (switch the node from its 1080p default), confirm the motion and composition are what you want, then commit to the 30-second render on base. Two generations, about 166 credits total at 480p (24 + 142), against 142 for a single blind attempt. The draft checks the prompt and the opening; it cannot show you second 22, so watch the full take, faces and product surfaces included, before you build on it.
FAQ
What is the longest AI video I can generate in one pass in 2026? On 8frame, thirty seconds, with Wan 3.0 (base and Prime) and Seedance 2.5. The lip-sync tools follow an audio track up to 35 seconds, but they animate a portrait rather than generate a scene. Longer material is joined in an edit.
Does a longer clip cost more per second? Not on the models here; they bill per second at a fixed rate for a given variant and resolution (OmniHuman 1.5 in 5-second steps). What changes is the risk: a failed generation is refunded automatically, but a finished take you do not like costs its whole duration.
Can I extend a clip instead of generating long? Google's Omni documentation describes extending a video by 10 seconds at a time, up to 40 seconds in total, through the Gemini API. On 8frame the Gemini Omni Flash node makes 3 to 10 seconds and its edit mode keeps the input length, so it does not extend. Grok Imagine has an extend mode on 8frame: 54 credits to add 5 seconds to a 5-second clip, billed at the 720p rate.
How do I join clips into a longer video on 8frame? On the canvas, the Montage node joins 2 to 10 clips with transitions for 10 credits per run, and cuts each clip to a maximum you set from 1 to 15 seconds (5 by default); the merged file has no sound. For longer clips, sound or captions, the Video Editor mode has a timeline with sound layers.
Is a 30-second single take actually better than six cuts? Only when the content is one continuous shot. An ad with six setups is six shots. Use length where the continuity is the point.
