Properties ⁨1⁩ property

providerSettings » bytedance » camerafixed camerafixed boolean Default: false

Controls whether the camera remains stationary during video generation. When enabled, the camera position and angle are fixed, preventing any camera movement, panning, or zooming effects.

When disabled (default), the model can incorporate dynamic camera movements such as pans, tilts, zooms, or tracking shots to create more cinematic and engaging video content.

This setting is useful when you need static shots or want to avoid camera motion that might distract from the main subject or action in the video.
