ProduceEditingProjectVideo - ApsaraVideo VOD - Alibaba Cloud Documentation Center

Operation description

Before you use this operation, ensure that you understand the billing methods and pricing of ApsaraVideo VOD. Online editing is a paid feature. For more information about billing, see Billing for video editing and production.
This operation returns the result of the task submission. The response does not guarantee that the video is produced. The production task is queued and executed asynchronously in the background.
The video resources in an online editing timeline can be materials from Material Management or videos from the Media Library. If you use videos from the Media Library, ensure that their status is Normal.
Videos are produced based on ProjectId and Timeline. The logic is as follows:
- ProjectId and Timeline cannot both be empty. Otherwise, the video cannot be produced.
- If ProjectId is empty and Timeline is not empty, an online editing project is automatically created based on the specified Timeline parameter. The materials referenced in the timeline are fetched and set as the materials for the project. Then, the video is produced.
- If ProjectId is not empty and Timeline is empty, the latest saved timeline is retrieved based on the ProjectId to produce the video.
- If neither ProjectId nor Timeline is empty, the video is produced based on the specified Timeline. The corresponding online editing project, including its timeline and materials, is updated. If you specify other fields, the corresponding fields of the online editing project are also updated.
The number of video tracks, image tracks, and caption tracks cannot exceed 100 for each.
The total number of materials cannot exceed 200. The total size of material files cannot exceed 1 TB.
The region of the input or output bucket must be the same as the region where you use the VOD service.
When the output is a video, the resolution of the final video is subject to the following limits:
- The width and height cannot be less than 128 pixels.
- The width and height cannot exceed 4096 pixels.
- The shorter side cannot exceed 2160 pixels.
After a video is produced, it is automatically uploaded to ApsaraVideo VOD. The VOD service then sends event notifications to indicate that media production is complete and video upload is complete. After the produced video is transcoded, additional event notifications are sent to indicate that transcoding for a single definition is complete and transcoding for all definitions is complete.
You can also add effects to the produced video. For more information, see Effects.

Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
