Inspirational Video

This example is a 28-second HD motivational video built from six VIDEO clips on one global timeline, two audio entries, and karaoke-style subtitles. These clips are not objects in the scenes array.

The complete JSON in this page is the runnable config for this example and has been checked against the current public render schema.

  "duration": 28,
  "backgroundColor": "#000000"
}

The clips are linked with id and transitionId. This is a visual element fragment from the complete project below:

{
  "type": "VIDEO",
  "id": "scene-1",
  "src": "https://www.pexels.com/download/video/4927963/",
  "width": 1280,
  "height": 720,
  "resize": "cover",
  "position": "center-center",
  "anchor": "center-center",
  "volume": 0,
  "videoBegin": 0,
  "videoEnd": 4.8,
  "enterBegin": 0.16,
  "exitEnd": 4.96,
  "transition": "fade",
  "transitionDuration": 0.6,
  "transitionId": "scene-2"
}

The recorded fixture mixes the same audio source twice at different levels. Its captions are authored separately; this fixture does not demonstrate automatic transcription or separate narration and music sources:

[
  {
    "src": "https://cdn.pixabay.com/audio/2026/02/24/audio_3f375fdf97.mp3",
    "volume": 1
  },
  {
    "src": "https://cdn.pixabay.com/audio/2026/02/24/audio_3f375fdf97.mp3",
    "volume": 0.2
  }
]

For new projects, use the current flat subtitle style fields. This subtitle fragment is the equivalent styling for the recorded example:

{
  "font": {
    "color": "#ffffff",
    "bold": true,
    "size": 86,
    "family": "Montserrat"
  },
  "position": "center-center",
  "stroke": { "width": 4, "color": "#000000" },
  "animation": "karaoke",
  "activeWord": { "color": "#f3efa2" }
}

How It Works

Each clip is a VIDEO element positioned on the global timeline with enterBegin and exitEnd. The source clips are muted with volume: 0, and the fixture's audio entries are mixed through the root audios array.

The first five clips declare transitions to the next clip:

Scene	Transition	Duration
scene-1 to scene-2	fade	0.6
scene-2 to scene-3	smoothleft	0.7
scene-3 to scene-4	fadeblack	0.6
scene-4 to scene-5	dissolve	0.6
scene-5 to scene-6	fadewhite	0.7

Full Config

The full JSON below is the recorded render's project payload, submitted under payload. Its source URLs and legacy subtitle.styles are retained to match the preview. For new projects, use the current subtitle fields above; do not combine them with styles. Validate a complete request with Validate and estimate before spending credits.

Key Takeaways

• Use id and transitionId to link video clips on one timeline.
• Set source video volume to 0 when narration should drive the audio.
• Karaoke accepts text-only captions and distributes word timing automatically; explicit word-level start/end values provide transcript-accurate timing.
• Keep background music low, often around 0.1 to 0.3, so it does not compete with narration.
