Buyer's Guide to Media and Entertainment Video Platforms 2016

If this sounds like a content management nightmare, it’s easy to see why a robust content management solution will be critical to your choice of an MEVP solution. 除了, 虽然, there are a few other things to consider when it comes to content management: DRM, 包括加密和水印, as well as applications for managing content processing workflows and job scheduling, to effectively process and manage digital media content in the cloud.

content管理选项, either homegrown ones offered by the MEVP or third-party options integrated into the MEVP, 平台间差异很大. So it pays to consider what your initial and ongoing uses of content management will entail.

搜索

Given the amount of metadata generated during the pre- and postproduction processes, 包括注释和日志, there’s an expectation that this metadata would be searchable throughout the production and delivery workflows. 事实并非如此.

A few MEVP offerings provide the ability to search through comments, and a few offer the same for metadata keywords added to the overall logging. MEVPs have been hard at work over the last year to expand their search capabilities, including the ability to search comments and keywords generated as part of subclips, with ways to retain associated metadata—internal to the MEVP solution—from rough cut to delivery format.

At least one system also allows round-trip metadata updates, meaning that anyone who has spent time inputting comments during logging will be happy to know that the comments are searchable to specific desktop nonlinear editing suites. This is useful for those who might have a multisite or multiplatform workflow, as well as for those who might be looking for a hybrid solution, with some on-prem production and cloud-based production and delivery.

身份验证和权限

mevp的安全选项各不相同, with some providing only role-based authentication, in which a user is assigned a specific role—commenter, 日志记录器, administrator—and then is permitted to view or manipulate content for a particular project.

其他人则更多地关注基于项目的身份验证, in which each project requires reassigning permissions to a particular user. 这种方法不太灵活，但可能更安全. 在这些系统中, no one is allowed to copy and paste assets between projects, 手动输入权限, to avoid anyone copying permissions into a project for which they’re not allowed to access content.

A few key MEVPs are offering the more flexible Active Directory (or LDAP) approach, which allows for authentication either by user or role.

存储

Once content is ready for delivery, there’s a question of storage. Many content delivery networks (CDNs) offer storage that complements their MEVP offering, but there are also a growing number of pureplay storage companies. These companies often have storage points of presence (POPs) at the same data centers that CDNs and MEVPs use, especially for content storage and delivery outside of the U.S. As such, the transfer from storage provider to MEVP service is surprisingly quick.

Even within an MEVP offering, there are a number of options. 例如，亚马逊网络服务 (AWS) there are at least three options: Amazon S3, EFS, and Glacier. 亚马逊指出，这些可以用于存档, content, 文件存储, but that it also offers interfaces to “specialized Digital Asset Management (DAM) and Media Asset Management (MAM) solutions from leading media software vendors,” in case the MEVP customer already has a solution in place.

最后把

今天的mvp有很多重要的特点. 我们已经触及了其中的一些, but there are many others— from dynamic advertising insertion to pay-per-view or event-payment gateways—that may be required for your particular MEVP needs.

Don’t forget to run a detailed use case on your workflow, keeping in mind that it may require specialized broadcast features that vary between the U.S.欧洲，甚至亚洲. 基于云的MEVP解决方案的可用性, including those that offer acquisition and production options, 因地理而异, but the needs of the majority of viewers correspond fairly consistently to the service offerings provided by MEVPs in those regions.
