You can configure Timeline to generate output videos in an online editing project based on your business requirements. This topic describes how to use the timeline data to implement common short video features.
Description
For more information about the parameters described in the following example, see Timeline: the information about the timeline of an online editing project.
Examples
Rotate a video from the landscape mode to the portrait mode and add black bars
To rotate a video from the landscape mode to the portrait mode, specify Width and Height in ProduceConfig based on the size of the video in the portrait mode when you call the ProduceEditingProjectVideo operation. Then, the system centers the video based on the width and height that you specified.

Note To change the color of the black bar, specify
"SubType": "Color" in Effects. For more information about the parameters in Effects, see Background settings. Rotate a video from the landscape mode to the portrait mode and blur the blank area
To rotate a video from the portrait mode to the landscape mode, specify Width and Height in ProduceConfig based on the size of the video in the landscape mode when you call the ProduceEditingProjectVideo operation. Then, the system centers the video based on the width and height that you specified. The filled area in the playback window is blurred.

Configure effects for subtitles
To configure effects for subtitles, add overwriting code to Content. The following rules apply:
- All overwriting code must begin with two backslashes (\\).
- All overwriting code must be enclosed in braces ({ }). You can include multiple lines of code in a pair of braces.
- The overwriting code applies to subtitles. To restore the original configurations, add the corresponding code to cancel the overwriting.
