| Parameter | Type | Required | Default | Min | Max | Allowed Values | Description |
|---|---|---|---|---|---|---|---|
video |
file | Yes | - | - | - | - | The 3D, CG, or game render you want to make look photorealistic. |
image |
file | No | - | - | - | - | An optional photo to set the realistic look of the opening frame. The rest of the video follows from it. |
prompt |
string | No | - | - | - | - | Describe the photorealistic result you want. |
negativePrompt |
string | No | - | - | - | - | Things to steer the result away from unwanted artifacts, styles, or defects. Comes pre-filled with common ones you can edit. |
intensity |
string | No | strong-v2 |
- | - | light, strong, strong-v2 |
How hard to push the render toward realism. Light keeps more of the original render’s look; Strong pushes further; Strong V2 is the newest, improved version. |
resolution |
string | No | 720p |
- | - | 480p, 720p |
The output quality (measured on the shorter side), keeping your source’s proportions. 720p supports clips up to ~6s; 480p up to ~15s. Higher resolution costs more. |
numFrames |
number | No | 121 |
1 | 361 | - | The total number of frames in the output. The video’s length is this divided by the frame rate (for example, 121 frames at 24 fps is about 5 seconds). More frames cost more. |
framesPerSecond |
number | No | 24 |
1 | 60 | - | How many frames play per second. Higher values look smoother. |
enableDetailRefine |
boolean | No | false |
- | - | - | Adds a second pass for a sharper, higher-detail result. This doubles the width and height (four times the pixels), so it’s slower and costs about 4× as much. |
detailRefineStrength |
number | No | 0.75 |
0 | 1 | - | How much the refine pass reworks the image. Higher values regenerate more detail. Only applies when Detail Refine is on. |
generateAudio |
boolean | No | true |
- | - | - | Includes a soundtrack in the returned video. On by default. |
enablePromptExpansion |
boolean | No | false |
- | - | - | Automatically expands your prompt into a richer description before generating. The “3DREAL” trigger is always kept. |
numInferenceSteps |
number | No | 15 |
8 | 30 | - | How many refinement passes the model makes (8-30). More can improve quality but take longer. |
guidanceScale |
number | No | 1 |
0 | 20 | - | How closely the result follows your prompt. Higher values stick to it more strictly. |
videoQuality |
string | No | high |
- | - | low, medium, high, maximum |
The overall quality preset for the output video. |
videoWriteMode |
string | No | balanced |
- | - | fast, balanced, small |
How the video file is saved: Fast prioritizes speed, Small prioritizes a smaller file, Balanced sits between. |
seed |
number | No | - | 0 | - | - | A number that makes results repeatable. Reusing the same seed and settings produces the same video; leave it empty for a different result each time. |
