Property descriptions

For more information about the properties in the following examples, see Timeline configuration.

Timeline examples

Convert a landscape video to portrait and add black bars

If the source material in the Timeline is a landscape video, call the Video Composition operation to submit a composition job and set the output to portrait orientation by specifying the ProduceConfig, Width, and Height fields. The system centers the source material based on the dimensions of the source and output videos.

	`{ "VideoTracks": [{ "VideoTrackClips": [{ "MediaId":"756620ed48c9af022c66ee1cbe2e**" },{ "MediaId":"8f5cdf044b059b3adc7967ba1cbe" },{ "MediaId":"70dc95c0e31b71edbfe76fa3691c**" }] }] }`

Note

To customize the color of the black bars, set "SubType": "Color" in the Effects field. For more information about the Effects parameters, see Effect Type: Background settings.

Convert a landscape video to portrait and add blurred areas

If a media asset in the Timeline is a landscape video, you can render it in portrait style. Call the Video Composition API to submit a composition job and set the Width and Height fields in the ProduceConfig parameter. The system centers the media asset based on the dimensions of the asset and the final video, and blurs the padded areas.

Add captions

Set the TimelineIn and TimelineOut fields to specify the start and end times for a caption. If these fields are not set, the caption is displayed throughout the entire video, which is a common approach for global captions.

Set local effects for captions

Add override code to the Content field to apply local effects to captions. The override code works as follows:

All override code starts with two backslashes (\\).
All local parameter override code must be enclosed in braces ({}). A single pair of braces can contain multiple override codes.
The override code affects the subsequent captions. To end the effect, you must add a corresponding closing override code.

Global effects and filters

To apply effects and filters to the entire video, add them to the EffectTrack property. You do not need to set TimelineIn and TimelineOut. The effects are rendered throughout the entire video.

Set a global background and a global logo

Configure "Type": "GlobalImage" to display an image throughout the entire video. You do not need to configure Duration.
