Correction, 2026-10-02: this page said a clip takes "about 35 seconds to about 6 minutes"; the slowest median we measured is almost 7 minutes (Seedance 2.0 with a video input), and the range now says so. The Gemini Omni Flash time of about 35 seconds was measured on 3 to 5 second clips only, and every mention of it now says that. The Seedance 2.0 comparison now uses the clip lengths we measured (up to 6 s and 7 to 11 s) instead of "5 or 10 seconds". The fastest-generator answer now says it covers only the models we measured. We removed claims we never measured: that re-generation is "the dominant factor", that serial generation is "the most common" delay, that "Turbo" is a price tier and that any reseller's speed claim is only about queueing. The relax-mode example is now quoted from Midjourney's own documentation.
Correction, 2026-09-30: the first version of this page lumped all Kling and Seedance models together, used 30 days of data and printed sample sizes. It now splits times by model, clip length and resolution over 120 days, and the image times are corrected: Nano Banana 2 takes under half a minute, not one to two minutes.
On 8frame, an AI video clip takes from about 35 seconds to almost 7 minutes to generate at the median, and the model decides most of that. Gemini Omni Flash returns a 3 to 5 second clip in about 35 seconds. A 5-second Kling v3 Standard clip takes about a minute, and Seedance takes 2 to 5 minutes, almost 7 with a video input. A 15-second Hailuo H3 clip at 2K takes almost 6 minutes. Images are faster: 26 seconds on Nano Banana 2, about 2 minutes on GPT Image 2.
Measured times by model
Time from pressing generate to the result arriving on the canvas, for completed generations on 8frame in the 120 days to 2026-09-30. Template examples are excluded, and each row is a model and setting with enough completed generations to report a median. One in ten generations took longer than the 90th percentile.

Models without enough completed generations in the window, Veo 3.1 and Wan 3.0 among them, are left out rather than guessed, so this page gives them no time.
What the numbers show
- Length costs time on Kling, much less on Seedance 2.0. Going from 5 to 10 seconds adds 60 to 70% on Kling v3 Standard and Kling 2.6 Pro, and nearly triples Kling 2.5 Turbo Pro. Seedance 2.0 at 720p takes a little over 3 minutes both for clips up to 6 seconds and for 7 to 11 seconds, and a little over 4 minutes from 12 seconds up.
- Resolution costs time on Seedance 2.5. A 5-second clip takes about 2 minutes at 480p and almost 5 at 720p.
- "Turbo" in a model name is not a speed promise. At the median, a Kling 2.5 Turbo Pro clip took longer than a Kling 2.6 Pro clip of the same length: 111 against 74 seconds at 5 seconds, 316 against 117 at 10.
- The tail is long on heavy models. Hailuo H3's slowest tenth (15 seconds at 2K) took over 12 minutes; Omni Flash's took under a minute.
Who sets the speed
8frame does not run the models itself: each job goes to the model maker or to a hosting provider such as fal or Replicate, and the result arrives when that provider finishes. The model and the provider's load set the speed. So when a product calls itself the fastest AI video generator, ask whether it runs its own models; if it resells someone else's, the lever it controls is its queue policy.
What actually makes a project slow
Queue policy. Some services put you on a slower lane on purpose. Midjourney's Relax Mode, for example, is unlimited, but requests "wait in line to be processed as GPUs free up", with waits of 0 to 30 minutes according to Midjourney's own documentation. See is unlimited AI video actually unlimited.
Re-generation count. Count your attempts, not only the render time. At three attempts per usable clip, a one-minute model is a three-minute shot and a five-minute model is a fifteen-minute shot. A model that lands the shot in fewer attempts can beat a faster one.
Serial instead of parallel. Generating twelve variants one at a time and watching each finish adds every wait together. On 8frame an account can run up to 10 generations at once, so start the set and review it when it lands.
Waiting for approval, not for pixels. On a client project the render takes minutes; a review round can take days. See how to set creative deadlines that hold.
How to make your own work faster
- Draft on a fast model, finish on a slow one. Gemini Omni Flash (about 35 seconds for a 3 to 5 second clip) for drafts, then the heavier model once for the shot that survived.
- Draft at 5 seconds. On Kling, a 5-second take comes back in a third to two thirds of the time of a 10-second one.
- Draft Seedance 2.5 at 480p. Less than half the wait of 720p, and less than half the price.
- Resolve composition on stills. Nano Banana 2 returns an image in under half a minute; settle the frame there before animating.
Prices for every model are in the AI video generator price per second table.
FAQ
What is the fastest AI video generator? Among the models we measured on 8frame, Gemini Omni Flash: about 35 seconds at the median for a 3 to 5 second 720p clip. Next come its video edit (49 seconds) and Kling v3 Standard, at about a minute for 5 seconds. Models we could not measure, such as Veo 3.1, get no time on this page.
How long does Kling take to generate? On 8frame, about a minute for a 5-second Kling v3 Standard clip at 720p, under 2 minutes for 10 seconds, and about 5 minutes for a 10-second Kling 2.5 Turbo Pro clip at 1080p.
How long does Seedance take? About 3 to 4 minutes for Seedance 2.0 at 720p (almost 7 with a video input), about 2 minutes for a 5-second Seedance 2.5 clip at 480p and almost 5 at 720p.
Why did my generation take ten minutes? A heavy model, a long clip, a high resolution, or a busy provider. On Hailuo H3 (15-second clips at 2K), one generation in ten took over 12 minutes.
Do I have to wait in a queue on 8frame? There is no plan-based priority tier and no relax mode: every plan runs at the provider's speed. The one limit is 10 generations running at once per account. We checked both in our code on 2026-09-30.
