You can aggregate a collection of images into a Gif or MP4 video file.

For mp4_from_images

"images" is the array of source images
"output_size": "1280x480" (Dimensions of output video)
"framerate_fps": 30 (Framerate in fps)
"pad": true (If resized, whether to add padding or not)
"padding_color": "#ffffff" (Color of padding if added)
"total_frames": 180 (Optional, can define to "loop" a particular number of frames)

Example:

{
    "application_id": "YOUR_APP_ID",
