Versioning and approval workflows in content management systems are used to track changes to video entries, maintain audit trails, and control publishing states. These workflows are essential for platforms where multiple contributors handle video content and where content must undergo review before being published. A structured system ensures that edits are recorded, previous versions are accessible, and only approved versions are made available to end users.
Setting Up Video Versioning in CMS
Versioning refers to the ability to track changes made to video content over time, allowing users to retrieve previous versions and maintain a record of edits. A good versioning system in the CMS will help content creators and editors work collaboratively while also preserving the integrity of the original video files.
1. Enabling Video Versioning
Most modern headless CMS platforms support content versioning, including video content. For instance, Strapi, Contentful, and Sanity provide built-in versioning features, where each change to a piece of content, including video metadata, creates a new version that can be accessed or reverted.
Here’s an example of versioning in Strapi using a content type for videos:
{
"id": "1",
"title": "Intro to CMS Video",
"url": "https://cdn.example.com/video.mp4",
"version": "v1.2.3", // New version after editing
"description": "An overview of CMS concepts.",
"updatedAt": "2023-09-22T12:34:56.000Z",
"createdAt": "2023-09-01T08:12:45.000Z"
}
Explanation:
- Versioning Field: The version field stores the version number (e.g., v1.2.3).
- Timestamps: createdAt and updatedAt help track when changes were made.
- This can be extended with a version history table or API to track each modification.
2. Using Metadata for Video Version Control
Adding metadata to videos allows for version control at a more granular level. For instance, each version could contain information such as the video resolution, bitrate, or format changes. This metadata helps keep track of quality improvements or adjustments during editing.
Example metadata for a video version:
{ "video_id": "12345", "version": "v2.0", "resolution": "1080p", "bitrate": "5000kbps", "file_format": "mp4", "editor_notes": "Added subtitles and improved color grading." }Approval Workflows for Video Content
Approval workflows in a CMS allow teams to review, approve, or reject video content before it goes live. This ensures that only authorized or finalized versions are displayed to end-users, maintaining quality control across your platform.
1. Defining Approval States
In a typical video approval process, videos undergo multiple stages: Draft, Review, Approved, and Rejected. Each stage of the workflow should be clearly defined and managed within the CMS.
Here’s an example of a content type with approval states:
{"title": "Corporate Training Video","url": "https://cdn.example.com/video.mp4","approval_status": "Review", // Possible values: Draft, Review, Approved, Rejected"createdAt": "2023-09-01T08:12:45.000Z","updatedAt": "2023-09-22T12:34:56.000Z","approvedBy": "admin","reviewComments": "Needs subtitle updates."}Explanation:
- Approval Status: This field tracks the current state of the video (e.g., Review, Approved).
- Review Comments: Content reviewers can leave feedback for the video creator or editor, ensuring that all changes are documented.
2. Implementing Role-Based Access Control (RBAC)
Role-based access control (RBAC) is a key component in managing video approval workflows. By implementing roles such as Editor, Reviewer, and Administrator, you can ensure that only authorized users can approve or reject content. In systems like Strapi or Sanity, you can configure permissions for different roles.
Example of role-based permissions in Strapi:
{ "role": "Editor", "permissions": { "video": { "create": true, "edit": true, "approve": false, // Editors can't approve, only reviewers can "delete": false } } }Explanation:
- Permissions: Editors can create and edit videos but cannot approve them.
- Roles: Reviewers have the ability to approve videos, while admins can manage all stages.
Integrating Approval Notifications
To streamline the approval process, notifications can be sent to relevant users when a video reaches a new approval stage. These notifications can be sent via email, within the CMS, or through a messaging platform like Slack or Teams.
Example using a notification API (pseudo code):
function sendApprovalNotification(videoId, status) {
const video = getVideoById(videoId);
if (status === "Review") {
sendEmailToReviewer(video.reviewerEmail, video);
} else if (status === "Approved") {
sendEmailToPublisher(video.publisherEmail, video);
}
}
function sendEmailToReviewer(email, video) {
// Send email to the reviewer
emailService.send({
to: email,
subject: "Video Review Request",
body: `The video "${video.title}" is ready for your review.`
});
}
Explanation:
- sendApprovalNotification: This function sends notifications based on the current approval status.
- Email Notifications: Different emails are sent to reviewers or publishers depending on the status update.
Best Practices for Video Versioning and Approval
- Version History: Always maintain a version history to avoid confusion. Each version of a video should be clearly identified with timestamps and version numbers.
- Clear Approval Stages: Define clear approval stages and ensure that everyone involved in the workflow is aware of their role and permissions.
- Collaboration: Use comments and notes in the approval process to facilitate collaboration between video creators, reviewers, and administrators.
- Automate Notifications: Set up automated notification systems to alert the necessary stakeholders when their input is needed, improving the speed of the approval process.
