Shotstack is a video, image and audio editing service that allows for the automated generation of videos, images and audio using JSON and a RESTful API.

You arrange and configure an edit and POST it to the API which will render your media and provide a file location when complete.

For more details visit shotstack.io or checkout our getting started documentation. There are two main API's, one for editing and generating assets (Edit API) and one for managing hosted assets (Serve API).

The Edit API base URL is: https://api.shotstack.io/{version}

The Serve API base URL is: https://api.shotstack.io/serve/{version}

GET /assets/render/{id}

A render may generate more than one file, such as a video, thumbnail and poster image. When the assets are created the only known id is the render id returned by the original render request, status request or webhook. This endpoint lets you look up one or more assets by the render id.

base URL: https://api.shotstack.io/serve/{version}

Parameters

Name In Type Required Description
id path string true The render id associated with the asset in UUID format

continued

Name Type Required Restrictions Description
start number true none The start position of the Clip on the timeline, in seconds.
length number true none The length, in seconds, the Clip should play for.

effect string false none A motion effect to apply to the Clip.

  • zoomIn - slow zoom in

  • zoomOut - slow zoom out

}

The output format, render range and type of media to generate.

Properties

Name Type Required Restrictions Description
format string true none The output format and type of media file to generate.

  • mp4 - mp4 video file

  • gif - animated gif

  • jpg - jpg image file

  • png - png image file

  • bmp - bmp image file

  • mp3 - mp3 audio file (audio only)

resolution string false none The output resolution of the video or image.

  • preview - 512px x 288px @ 15fps

  • mobile - 640px x 360px @ 25fps

  • sd - 1024px x 576px @ 25fps

  • hd - 1280px x 720px @ 25fps

  • 1080 - 1920px x 1080px @ 25fps

aspectRatio string false none The aspect ratio (shape) of the video or image. Useful for social media output formats. Options are:

  • 16:9 - regular landscape/horizontal aspect ratio (default)

  • 9:16 - vertical/portrait aspect ratio

  • 1:1 - square aspect ratio

  • 4:5 - short vertical/portrait aspect ratio

  • 4:3 - legacy TV aspect ratio

size Size false none Set a custom size for a video or image. When using a custom size omit the resolution and aspectRatio. Custom sizes must be divisible by 2 based on the encoder specifications.
fps integer false none Override the default frames per second. Useful for when the source footage is recorded at 30fps, i.e. on mobile devices. Lower frame rates can be used to add cinematic quality (24fps) or to create smaller file size/faster render times or animated gifs (12 or 15fps). Default is 25fps.

  • 12 - 12fps

  • 15 - 15fps

  • 24 - 24fps

  • 25 - 25fps

  • 30 - 30fps

scaleTo string false none Override the resolution and scale the video or image to render at a different size. When using scaleTo the asset should be edited at the resolution dimensions, i.e. use font sizes that look best at HD, then use scaleTo to output the file at SD and the text will be scaled to the correct size. This is useful if you want to create multiple asset sizes.

  • preview - 512px x 288px @ 15fps

  • mobile - 640px x 360px @ 25fps

  • sd - 1024px x 576px @25fps

  • hd - 1280px x 720px @25fps

  • 1080 - 1920px x 1080px @25fps

quality string false none Adjust the output quality of the video, image or audio. Adjusting quality affects render speed, download speeds and storage requirements due to file size. The default medium provides the most optimized choice for all three factors.

  • low - slightly reduced quality, smaller file size

  • medium - optimized quality, render speeds and file size

  • high - slightly increased quality, larger file size

range Range false none Specify a time range to render, i.e. to render only a portion of a video or audio file. Omit this setting to export the entire video. Range can also be used to render a frame at a specific time point - setting a range and output format as jpg will output a single frame image at the range start point.
poster Poster false none Generate a poster image from a specific point on the timeline.
thumbnail Thumbnail false none Generate a thumbnail image from a specific point on the timeline.
destinations [anyOf] false none A destination is a location where output files can be sent to for serving or hosting. By default all rendered assets are automatically sent to the Shotstack hosting destination. DestinationShotstack is currently the only option with plans to add more in the future such as S3, YouTube, Vimeo and Mux. If you do not require hosting you can opt-out using the exclude property.
