Today's video content is more than ever before, accounting for 80% of today's Internet traffic. However, without a simple method to organize, store and access these contents, they are just a pile of digital sundries. By acting as the central repository of media assets and improving the efficiency of online video distribution, the video content management system (CMS) can effectively improve the chaos of video content.
What is a video CMS?
Video content management system, namely video CMS, is an application platform for managing video assets. Like any excellent content management tool, video CMS acts as a database, simplifying the process of storing, finding and disseminating digital assets.
Organizing is a key capability of video CMS, and searchability is its direct advantage. These digital libraries are important for hosting, classifying, and accessing the entire content publisher's video archives. Both content publishers and end users can quickly find the video they are searching for according to attributes such as title, keyword or content category.
By using the video CMS platform, these data can be automatically extracted or manually entered. For more advanced video CMS platforms, artificial intelligence (AI) can also be used to quickly analyze the content and index it accordingly.
Finally, the CMS interface can also contain analysis related to video performance and viewer data, which helps provide help information for future decisions and makes the entire workflow more intuitive.
All these make it easier for live broadcasting companies to manage content internally and share content externally.
Why use video CMS?
Imagine buying a new house and finding the attic full of unmarked DVDs. Even worse, what if these DVDs were scattered throughout the house instead of being concentrated in one place?
These DVDs are likely to have some collection value (after all, the "Dragon Ball Z Suit" is worth $800 on eBay). However, if there is no way to quickly sort and classify these DVDs, you may be more inclined to dispose of them. After all, what is the value of video content that is difficult to organize, store, and share?
Video CMS solves the above requirements through multiple automated content management processes and hosting online video in one place. Enterprises can easily transfer and manage video files by relying on video CMS tools without worrying about any IT problems.
For publishers, this means improving data input efficiency. CMS can quickly extract, mark and store content, and automatically perform all tasks in this process. For example, by generating and storing metadata about uploaded videos, CMS removes a part of the burden that the live broadcast company originally had to bear.
For end users, this means that content can be discovered more quickly. CMS allows viewers to search for content in the system and supports playing at any time, thus leaving more time for users to watch the searched video.
For both parties, CMS can be used to generate recommended video content according to the user's historical viewing records. This brings more views to content producers (views are revenue), and also brings better personalized experience to the audience. In other words, all participants are win-win.
Advantages of video CMS
In a word, the value of CMS is closely related to media data and the following easier to find content. Specifically, CMS is:
Centralized management: When content is stored in a single system, it is easier to track, manage, and locate.
Repeated and expanded use: Video CMS allows live broadcast companies to reuse content that may be lost in the storage process.
User friendly access: The video CMS platform provides a simple way for end users to search and discover content.
How video CMS works
Extraction and tagging
The core of video CMS is an API for managing video assets. It distinguishes each file by extracting, storing and labeling the video content through metadata. Live broadcast companies can upload one or more files to the system, or even use the live to VOD function to record videos in the live stream.
The video CMS collects data related to each file in the following three ways:
Extracted data: information about the video, such as duration, resolution and codec used, can be automatically extracted from the file.
User input data: video tags based on the internal structure of the organization, such as themes or participants, can be manually input by individuals when uploading each file.
Machine generated data: Artificial intelligence (AI) and machine learning (ML) can also be used to collect more information. By capturing technology, object detection and other computer vision technology to obtain audio data to achieve.
Through the management interface, the publisher can also customize the category and hierarchy of videos, associate users with each file by setting the status, and even update individual and batch videos. For example, administrators may want to mark videos as published/unpublished or generate playlists for end users.
video processing
The video CMS prepares for video transmission by processing each file. This includes transcoding and packaging the video for sending to any endpoint. In this way, whenever someone chooses to watch a video file, CMS will provide the video format most suitable for their device and connection.
Turn on the search function
Finally, the API can also realize the video discovery function. This allows users to easily access content. Users can enter keywords related to video topics, or further deepen and refine their search based on categories and tags. Once users select a video, they can watch it anytime and anywhere thanks to ABR technology.
What functions can video CMS provide?
Key functions of video CMS include:
Transcoding and packaging: If every audience has a 4K home theater connected to the high bandwidth Internet, the transmission of video content will be very easy. But this is not the case. Today's audience will use various devices to access streaming media anytime, anywhere. Different screens and different network bandwidth make video transcoding and processing become critical. In addition to enabling adaptive code streams, this feature also allows you to repackage content into various formats for effective playback on any device.
Live to VOD: If you often watch live content, but want to be able to create video on demand (VOD) content from live streams in real time, you will want to find a video platform that supports live to VOD. With this function, you can quickly add real-time content to your video library, and gain additional profit opportunities by reusing the content.
Flexible metadata modeling: Don't let your video CMS provider impose restrictions on the structure of your video data. The ability to add new fields and categories provides flexibility to define the most meaningful internal organizational structure for your business.
Automatic metadata generation: Automatic generation of metadata such as codec, resolution, and duration can speed up content tagging. The more information, the better - that's why you need a video CMS to automate some processes.
Simple and flexible search: Benjamin Franklin said that every minute you spend on organizing affairs can win you an hour. However, this sentence only applies to such a video CMS tool: everyone who uses this technology can quickly locate the content they want to find. Simple and flexible search ensures this.
API access: API access to video CDN ensures that you can easily integrate the tool with other systems and control your video hosting experience. Although most video CMS platforms have an intuitive user interface (UI), API access means that you are not bound by a specific UI.
Advanced video CMS contains more complex functions, including:
Workflow modeling: Workflow modeling allows you to customize content roles and states to send videos appropriately. This function effectively simplifies cross organizational management by describing authors, editors, publishers, and unpublished and published lifecycle states.
Batch transfer: Anyone who wants to migrate video from another platform will benefit from the video CMS with batch transfer function, which can move hundreds of thousands of files at a time.
Playlist generation and play: Playlist can program multiple groups of videos into linear channels to play within a specified time period. This function supports the creation of any content, from digital advertising to enterprise news, to the all-weather broadcast service of OTT platform with selected linear channels. The advanced playlist function also includes support for advertisements (front, middle, and rear patch advertisements), and the function of mixed live broadcast content.
AI/machine learning: AI/ML tools for automatic transcription, topic detection, target recognition and caption generation are expected to replace manual methods to classify video content. Therefore, AI/ML can improve the searchability of content and provide better user experience for everyone using the platform. For example, all videos containing medical related keywords may be automatically grouped into the "medical" category of an organization. Alternatively, videos containing illegal content (such as nude) may be automatically tagged for further review.
Integrated analysis: data analysis helps to improve QoE, content classification, advertising positioning, etc. If you have a video CMS with this function built in, it means that you can make visual decisions driven by data in the whole workflow.
Video clip editing and editing: It is a tool for clips, wonderful content editing and simple editing of videos in the video library. It provides a way to reuse content and enhance the value of videos. In this way, you can publish short videos, make exciting clips of live activities, clip recorded videos or modify content in other ways on social media platforms such as Instagram, and make core videos of all versions available.
Independent services and integrated solutions
The video CMS software can be purchased either as an independent product or as an integrated component of the enterprise video platform. Integrated solutions are often preferred because they simplify the infrastructure of publishers and make it easier to create linear channels that mix live and on-demand content.
In addition, finding a single vendor solution for all your video technology needs is the key to improving the observability of the entire video delivery workflow. For a long time, online video has been plagued by complex multi vendor workflows. The integrated video CMS solution reduces this complexity and ultimately provides a smoother experience for end users.
