Why a video generator needs multiple AI models
There's no universal 'best' model. One gives you a clip with built-in sound, another produces a longer scene, a third accepts video or audio as a reference. With just one model, you bend your script to fit its limits. With several, you pick a model that fits your scene.
Reelora is a video generator where all these models live in one account. No need to set up separate subscriptions at Google, ByteDance, Kuaishou, xAI and OpenAI or shuffle files between websites. Pick a provider, model and parameters, see the price before you start, and generate.
The key thing is that clips from different models combine into one video. A scene from Veo, a scene from Kling, footage from your phone — put them together, add voiceover, subtitles and editing. We show how it all works from concept to finished video in the Reelora video generator overview.

Picking the right AI video model for your task
A finished video from multiple scenes with one click
Veo 3.1 or Grok. They're billed per clip, so a video with dozens of scenes stays affordable, and they work in automatic assembly.
One long, continuous scene
Seedance 2.5 Omni — up to 30 seconds. Kling 3.0 or Seedance 2 — up to 15. Grok gives up to 15 seconds and works in automatic assembly.
Need to repeat a movement or sound
Seedance Omni: accepts video and audio as reference. Omni Flash also takes video reference (Video → Video mode).
A frame between two images
Veo 3.1 and Seedance 2 let you set first and last frames, and the model builds motion between them.
Cinematic widescreen shot
Seedance has a 21:9 format. For shorts in any model, pick 9:16.
Quick and affordable drafts
Grok Lower, Seedance 2 Mini, or Kling 2.5 in Relax mode. Found a working prompt? Generate the final version in a better model.
Photo models comparison
| Model | Resolution and formats | Features | References |
|---|---|---|---|
| Nano Banana Pro / 2 / 2 Lite (Google) | 1K, 2K; 1:1 to 16:9 | Core models for frames and references | Up to 3 images |
| GPT Image 2 (OpenAI) | 1K, 2K, 4K; up to 21:9, 3:2, 2:3 | Low / Medium / High quality, transparent background | Up to 5 images |
| Grok Image (xAI) | 16:9, 9:16, 1:1 | Up to 8 images per query, Speed and Quality modes | Up to 4 images |
Photo models: why they're in a video studio
A good image is the foundation of good video. A character portrait, a location view, a product on a clean background — these become references that help the video model keep the scene consistent. And they work as frames for animation and covers.
Nano Banana is the workhorse for frames and references; more detail in the Nano Banana overview. Pick GPT Image 2 when you need 4K, an unusual format like 21:9, or an image with a transparent background — for instance, a product or logo to layer over video. Grok Image is handy when you want to see 8 variations at once and pick the best.
How pricing models affect your choice
Models are billed differently, and it's worth considering at the script stage. Veo and Grok charge per clip. Seedance and Kling charge per second: a 10-second scene costs twice as much as a 5-second one. Photos are billed per image, and GPT Image 2 pricing also depends on quality and resolution.
We don't quote exact prices here on purpose: they change. In Reelora you see the cost before each generation, you pay only for what actually gets generated, and our rates are among the lowest on the market. The practical rule: find your scene's look on a lighter model or low resolution, then move to a pricier model once your prompt is working.

Questions about AI video models in Reelora
What AI video models are available in Reelora?
Veo 3.1 Lite and Fast, and Omni Flash from Google. Grok Video and Grok Lower from xAI. Seedance 2, 2 Mini, 2 Omni and 2.5 Omni from ByteDance. Kling 3.0, 2.6 and 2.5 from Kuaishou. For photos — Nano Banana, GPT Image 2 and Grok Image.
Do I need to pay for each model separately?
No separate subscriptions. All models are available in one Reelora account, and you pay only for what you actually generate.
Which AI model is best for video?
It depends on the scene. For a video with many scenes in one click — Veo 3.1 or Grok. For a long, continuous scene — Seedance or Kling 3.0. For a scene based on video or audio reference — Seedance Omni. Most reliable: generate a scene with two models and keep the better take.
Can I mix different models in one video?
Yes. Each video scene is separate, so you can pick its own model or drop in your own footage. Editing will sync everything to the voiceover.
Which model gives the longest clip?
Seedance 2.5 Omni — up to 30 seconds. Then Kling 3.0, Seedance 2 and Grok — up to 15 seconds.
Which models generate video with sound?
Veo 3.1, Omni Flash, Grok and all Seedance models. Kling has sound only in version 2.6 with Professional + Audio mode. Without sound, add voiceover and music in the finished video.
Reelora, Relora or Rilora — which is right?
The correct name is Reelora. In search, people often type Relora or Rilora by mistake, and that's fine: one website — reelora.cc, one AI video generator.
Will new models be added?
The model catalog in Reelora grows as new models appear that solve new tasks. When a new one gets added, it goes straight into the model picker list. The current lineup is always visible in the studio itself.
