Top-level properties in RenderScript
These are the top-level properties that make up a RenderScript JSON file.
Output format
The file format for the rendered output. Use 'mp4' for videos, 'jpg' or 'png' for static images, and 'gif' for animated images.
Example
"output_format": "mp4",Default
"output_format": "jpg",Render dimensions
The width and height in pixels for the rendered output. When omitted, uses the dimensions of the first input media file.
Example
"width": 1280,
"height": 720,Defaults
"width": null,
"height": null,Frame rate
Frame rate in fps for video output. Defaults to the highest frame rate among input videos, or 60 fps if no videos are present.
Example
"frame_rate": 25,Default
"frame_rate": null,Duration
Duration of the output video in seconds. When omitted, automatically calculated based on element timing and content.
Example
"duration": 10,Default
"duration": null,Snapshot settings
Controls where a preview image is created from the video. 'snapshot_time' specifies the time in seconds within the video to capture the image. By default, the snapshot image is exported alongside the video output as a JPEG file, but 'snapshot_location' can be used to replace either the first frame ('start') or last frame ('end') of the video instead.
Example
"snapshot_time": 5.5,
"snapshot_location": "start",Defaults
"snapshot_time": null,
"snapshot_location": null,Emoji style
Sets the emoji design style used throughout the render. Available options are 'facebook', 'google', 'twitter', or 'apple'.
Example
"emoji_style": "apple",Default
"emoji_style": "facebook",Elements
An array of elements that make up this video or image.
Example
"elements": [
{
"type": "text",
"text": "Hello, world!",
"fill_color": "#ffffff"
}
],Default
"elements": [],
