Solid background colours and other containers can be selected in the model options.
Gemini Omni Flash Edit
$0.12/s of input (720p)
Gemini Omni Flash 1.1 Edit takes a video you already have and applies a described change to it — recolour an object, change the setting, remove an element — and returns the clip re-rendered. Simple instructions work best; adding 'Keep everything else the same' helps preserve the rest of the scene. There is no duration control: the output runs as long as your source clip. There is no aspect control either — the resolution you pick (360p, 720p, 1080p or 4K) sets the canvas, and your clip is re-framed into it, so a square source comes back widescreen. Billing is per second of output at the chosen tier, at the model's cost plus a flat 20% platform fee, shown before you spend. Voice editing is not supported, and editing uploaded videos is unavailable to users in the EEA, Switzerland and the UK.

The output follows the input image's framing, at 360p, 540p, 720p or 1080p and any duration from 1 to 15 seconds, with the same five stylised looks as the text-to-video entry. Billing is per second of output and rises with the tier, at the model's cost plus a flat 20% platform fee, shown before you spend. On FairStack this model renders silent video — see the text-to-video entry for why audio is switched off.
PixVerse V6 T2V
$0.054/s (720p)
PixVerse V6 is the current PixVerse generation. It generates short video from a text prompt across four resolution tiers (360p, 540p, 720p, 1080p) and eight aspect ratios including 21:9, at any duration from 1 to 15 seconds — V5.6 accepted only 5, 8 or 10. It also offers five stylised looks — anime, 3D animation, clay, comic and cyberpunk — selectable per generation. Billing is per second of output and rises with the tier, at the model's cost plus a flat 20% platform fee, shown before you spend. On FairStack this model renders silent video. The provider's optional soundtrack is priced on a different scale for every resolution tier, which our billing cannot represent yet, so audio is switched off rather than charged incorrectly.
PixVerse V6 Transition
$0.054/s (720p)
PixVerse V6 Transition takes two images — a first frame and a last frame — and generates the motion between them. Both frames are required. Four resolution tiers (360p, 540p, 720p, 1080p), eight aspect ratios, and any duration from 1 to 15 seconds. Billing is per second of output and rises with the tier, at the model's cost plus a flat 20% platform fee, shown before you spend. On FairStack this model renders silent video — see the text-to-video entry for why audio is switched off.
Seedance 2.5
$0.378/s (720p)
Seedance 2.5 is the next generation of ByteDance's Seedance video model. Like the rest of the Seedance family it is multi-mode from one model: drive it with a text prompt, a single first frame, a first and last frame for interpolation, or a set of reference images and audio clips. FairStack detects the mode from your input. It renders 480p, 720p, or 1080p in seven aspect ratios (including 21:9 and adaptive), with synchronized audio generated in the same pass. On FairStack a clip runs from 4 to 16 seconds. The model itself supports up to 30 seconds and larger reference sets; FairStack does not expose those yet. Reference videos are not accepted on FairStack yet. Billing is per second of output at the provider rate for the resolution you choose, plus the flat 20% platform fee, shown before you spend.
Seedance v1.5 Pro
$0.078/s (720p, no audio, 4 s clip)
Seedance v1.5 Pro I2V is ByteDance's image-to-video model that animates still images into 5-second video clips at 720p resolution. Upload a reference image and the model generates natural motion while preserving the visual fidelity of the source material. Hosted on RunPod for reliable serverless infrastructure. The model excels at bringing static images to life with coherent motion that respects the original composition. Character animations, product reveals, and scene transitions maintain the color palette, lighting, and style of the input image. At 720p output, the results are suitable for social media and web content. The tradeoff is shorter clip duration and slightly less sophisticated motion physics. Ideal for animating product images, creating social media video from existing photography, and character animation from reference art. Available on FairStack at infrastructure cost plus a 20% platform fee.

Veo 3.1 Quality
$0.19125/s (1080p, 8 s clip)
Google Veo 3.1 Quality is the premium tier of Google's video generation model and the only video model that generates both 1080p video and synchronized audio in a single generation pass. No other model combines video and audio generation into one step, eliminating the need for separate audio production and synchronization. Top-tier visual quality (0.92 score) and motion quality (0.90) place it at the pinnacle of AI video generation capability. The 1080p output resolution is the highest available from any video model, delivering detail that is suitable for professional presentations and large-screen viewing. Native audio generation produces synchronized sound effects, ambient audio, and environmental sounds that match the visual content. Compared to Kling 3.0 Pro, Veo 3.1 Quality matches or exceeds visual quality while adding native audio and higher resolution. Against a workflow combining a separate video model plus audio generation, the one-step approach is simpler but may cost more. Maximum duration is 8 seconds per generation. Best suited for professional video production where both 1080p resolution and synchronized audio are required, premium marketing content, and workflows where the convenience of one-step video-plus-audio generation justifies the premium price. Available on FairStack at infrastructure cost plus a 20% platform fee.

WAN 3
$0.24/s (1080p)
WAN 3.0 is the current generation of Alibaba's WAN family, released in August 2026. It generates audio in the same pass as the picture, so dialogue, music and effects arrive already in sync, and it renders natively at up to 1080p. Three resolution tiers (480p, 720p, 1080p) and an adaptive aspect mode that lets the model choose framing from the prompt. Billing is per second of output, at the model's cost plus a flat 20% platform fee, shown before you spend. Upstream, WAN 3 accepts up to 30 seconds in a single generation. On FairStack it is currently capped at 16 seconds, which is the platform-wide ceiling for every video model — so the longest-form capability is not yet exposed here. Available at infrastructure cost plus a 20% platform fee.
WAN 3 I2V
$0.24/s (1080p)
WAN 3.0 Image-to-Video is the image-conditioned half of Alibaba's current WAN generation. It animates your start frame and generates audio in the same pass, so dialogue, music and effects arrive already in sync. The output follows your start frame's framing. Supplying an end frame turns the same endpoint into a first-to-last-frame interpolation. Three resolution tiers (480p, 720p, 1080p); billing is per second of output and rises with the tier, at the model's cost plus a flat 20% platform fee, shown before you spend.

Frequently asked questions
How many AI video models does FairStack offer? +
FairStack lists 144 selectable models across all modalities. Video alone is 62 — text-to-video, image-to-video, and video-to-video — filtered by each model's real capability flags.
How is video priced? +
Video is charged per second at the model's rate times 1.20. We never print a single flat price for a clip, because duration and resolution change the cost. Example: Kling 3.0 Standard is $0.12/s.
Can I use Veo 3.1 Fast for text-to-video? +
Not on FairStack. Veo 3.1 Fast is image-to-video only on this platform. It appears on the image-to-video page and never on text-to-video.
