The Manual Postback feature is for associating caption files with assets hosted on a 3rd party platform that is linked to your 3Play Media account. This feature can be useful for users with linked accounts that do not have postback captions enabled as it gives users the ability to send captions back to the hosting platform on a file by file basis, as opposed to having all captions sent back to the hosting platform immediately upon completion of the transcription process.
Furthermore, Caption Import Service subscribers can import pre-existing captions and/or subtitles to their account, associate the 3Play file with the host platform by using the Connect to Linked Account feature, and then use the Manual Postback feature to associate the captions with the asset on the 3rd party platform.
Prerequisites
- For the Manual Postback feature to work the user must have a linked account with a 3rd party video hosting AND the 3Play Media file first must be connected to the linked account.
Steps to Manually Postback to a Linked Account
