Concatenate multiple videos

This example shows how to combine multiple videos into one using RenderScript.

Step 1
Declare two videos

Declare two video elements. Make sure that they are on the same track to have them play after one another.
curl -X POST https://api.creatomate.com/v2/renders \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer YOUR_API_KEY_HERE" \
     -d '{
  "output_format": "mp4",
  "width": 1920,
  "height": 1080,
  "elements": [
    {
      "type": "video",
      "source": "https://cdn.creatomate.com…/demo/video1.mp4",
      "track": 1
    },
    {
      "type": "video",
      "source": "https://cdn.creatomate.com…/demo/video2.mp4",
      "track": 1
    }
  ]
}'

Step 2
Add an optional transition

To apply a transition effect between the videos, add an animation to the second video, with 
transition
set to 
true
.
curl -X POST https://api.creatomate.com/v2/renders \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer YOUR_API_KEY_HERE" \
     -d '{
  "output_format": "mp4",
  "width": 1920,
  "height": 1080,
  "elements": [
    {
      "type": "video",
      "source": "https://cdn.creatomate.com…/demo/video1.mp4",
      "track": 1
    },
    {
      "type": "video",
      "source": "https://cdn.creatomate.com…/demo/video2.mp4",
      "track": 1,
      "animations": [
        {
          "duration": 1,
          "transition": true,
          "type": "fade"
        }
      ]
    }
  ]
}'
