7 parameters · 0 required · 7 optional
| Parameter | Type | Required | Description |
|---|---|---|---|
video | string | Optional | The URL of the video to upscale. |
fidelity | string | Optional | The enhancement intensity. 'high' applies mild enhancement while keeping visual texture close to the source video. 'medium' provides a balanced image quality enhancement. · Options: high, medium · Default: "high" highmedium |
target_fps | string | Optional | The target FPS of the video to upscale. · Options: 30fps, 60fps · Default: "30fps" 30fps60fps |
scale_ratio | number | Optional | The scaling ratio for the output video resolution. When set, overrides target_resolution and scales the input resolution by this factor (e.g., 2.0 doubles the resolution). Range: 1.1 to 10.0. Please note that this is valid only up to 4k resolution, and trying to scale beyond 4k will result in an error. (4k is defined as having atotal pixel count of 3840x2160). · Min: 1.1 · Max: 10 |
enhancement_tier | string | Optional | The enhancement quality tier. 'fast' provides essential upscaling with good speed, 'standard' uses adaptive algorithms for better visual texture, 'pro' uses large-model restoration for cinematic quality (longer processing time), and 10 times the cost of `standard` and `fast`. · Options: fast, standard, pro · Default: "standard" faststandardpro |
target_resolution | string | Optional | The target resolution of the video to upscale. · Options: 1080p, 2k, 4k · Default: "1080p" 1080p2k4k |
enhancement_preset | string | Optional | The enhancement preset optimized for specific video scenarios. 'general' is a general-purpose template, 'ugc' targets user-generated short videos, 'short_series' is for short dramas, 'aigc' is for AI-generated content, and 'old_film' is for classic film restoration. · Options: general, ugc, short_series, aigc, old_film · Default: "general" generalugcshort_seriesaigcold_film |

Bytedance Video Upscaler
bytedance/upscaler/video upscales existing footage toward 1080p, 2K, or 4K while improving perceived detail across the entire clip. Temporal enhancement is applied consistently from frame to frame, reducing the shimmer and changing texture that can appear when still-image sharpening is applied independently to video. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.
For production work, Scenario presets and fidelity choices allow restoration to be balanced against source preservation, while 30 fps and 60 fps delivery cover conventional and high-motion masters. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.
Highlights
Temporal detail recovery improves clarity without introducing frame-to-frame texture flicker.
Resolution enhancement supports 1080p, 2K, and 4K finishing targets.
Scenario-aware restoration adapts enhancement to different footage characteristics.
Motion-consistent processing preserves moving subjects and camera transitions during enlargement.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The model's named workflow matches the source material and intended output | A different input modality or model route is required |
| A managed asynchronous result is suitable for the production pipeline | A synchronous, interactive editor is essential |
| The documented controls cover the required duration, framing, or format | The project needs controls outside this endpoint's schema |
| Creative iteration benefits from a repeatable request structure | Exact deterministic pixels, frames, geometry, or samples are mandatory |
| A finished downloadable media asset is the desired deliverable | Editable source layers or a native project file are required |
Prompt Guide
For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
