Techniques for transition files for use with content files and related metadata are described. In an example, a system determines a cue point of a video content file at which targeted content is to be presented. The system determines that a set of transition frames is to be presented at a start of a presentation of the targeted content or at an end of the presentation of the targeted content. The set of transition frames are available from a transition file that is separate from the video content file. The system generates metadata associated with the video content file. The metadata indicates that the set of transition frames is to be presented and an association of the set of transition frames with the cue point.

Transition file for use with content file and related metadata

Disclosed are various embodiments for seamless insertion of modified media content. In one embodiment, a modified portion of video content is received. The modified portion has a start cue point and an end cue point that are set relative to a modification to the video content to indicate respectively when the modification approximately begins and ends compared to the video content. A video coding associated with the video content is identified. The start cue point and/or the end cue point are dynamically adjusted to align the modified portion with the video content based at least in part on the video coding.

Seamless insertion of modified media content

Systems and methods described herein provide for novel boundary generation features for interleaving additional content into media content. Media content may be received which includes a video and audio portion. An unencrypted encode of the video portion may be generated. A first set of time stamps for the video portion may be generated using a computer vision algorithm. A second set of time stamps for the video portion may be generated for identifying IDR frames using a first algorithm. A third set of time stamps may be generated to serve as boundaries for interleaving additional content into the media content based on a priority algorithm that uses the first set of time stamps and the second set of time stamps. The video portion may be encoded using the third set of time stamps to determine the IDR frames for the media content.

Generating boundary points for media content

A system for utilizing media content reference point information to perform media content encoding, and supplemental content stitching and/or insertion. Media content can be encoded and packaged based on boundaries of the media content. The boundaries can be received from a third-party and/or generated via an automated process. Target boundaries can be selected based on accuracy levels associated with the received and/or generated boundaries. Supplemental content can be stitched and/or inserted into packaged media content based on audio and video content of the packaged media content being aligned.

Media content boundary-aware encoding

Media content boundary-aware supplemental content management

Methods and apparatus are described that relate to stitching different streams of high dynamic range (HDR) content together and handling HDR metadata mismatches between the differently produced content streams.

High dynamic range video content stitching

Techniques for video fragment aware audio packaging that ensure a periodic and best alignment of audio and video fragments at any corresponding audio and video fragments are described. As one example, a video fragment aware audio packaging service determines a number of audio frames for a corresponding video fragment of video frames and generates an audio fragment that includes those audio frames, with flexible choices of video fragment duration, which may be considered and decided for device compatibility or content encoding optimization purposes.

Video fragment aware audio packaging service

Techniques enabled by the present disclosure allow a media content service to support different playback modes in the presence of variations in media content asset types and viewer device capabilities. The techniques enabled by the present disclosure further allow encoding media content with playback bitrates targeted for streaming playback mode and playback bitrates targeted for download playback mode, and managing manifest data to allow viewer devices to select between different playback bitrates for a particular playback mode with greater precision.

Managing playback bitrate selection

Techniques enabled by the present disclosure enable media content to be split into sections that can be encoded by multiple video encoders. The disclosed techniques further enable the separately encoded sections to be stitched back together using coordination logic that does not require bi-directional communication between encoding processes.

Split-and-stitch media content encoding

Methods and apparatus are described for providing media presentations that include content originating from multiple sources. Techniques disclosed include server-side logic for inserting secondary content, such as advertisements, into primary content, such as a VOD presentation. Systems implementing the disclosed techniques can support different viewer device capabilities relating to displaying media presentations that include content from multiple sources.
