Methods and systems for managing streaming video sub-clips for frame accurate server side content insertion

A computer-implemented method, the method comprising:

• accessing a set of interstitial breakpoints for a first transcoded item of video content comprising a plurality of segments;
• applying a window of a first size for a first interstitial breakpoint to a first portion of a first item of video content, wherein the first portion of the first item of video content has been previously transcoded, and the window is larger than a segment of the first transcoded item of video content in size;
• generating new subclips for the first portion of the of the first item of video content, the new subclips comprising a first subclip and a second subclip;
• re-transcoding the first portion of the of the first item of video content comprising the new subclips within the window, wherein a boundary between the first subclip and the second subclip define a location for the first interstitial breakpoint;
• identifying existing segments of the first transcoded item of video content that can be used with the set of interstitial breakpoints without re-transcoding, wherein the existing segments of the first transcoded item of video content that can with the set of interstitial breakpoints are associated with corresponding existing playlists;
• generating new playlists for the new subclips;
• transmitting the new playlists for the new subclips and the existing playlists to a client, wherein the client is configured to request content in accordance with the new playlists and the existing playlists;
• and
• streaming the existing segments and the new subclips to the client in accordance with requests from the client.

Non-transitory computer readable memory having program instructions stored thereon that when executed by at least one computing device cause the at least one computing device to perform operations comprising:

• receive a set of breakpoints for a first transcoded item of video content comprising a plurality of segments;
• apply a window of a first size for a first breakpoint to a first portion of a first item of video content, wherein the first portion of the first item of video content has been previously transcoded, and the window is larger than a segment of the first transcoded item of video content in size
• generate new subclips for the first portion of the of the first item of video content, the new subclips comprising a first subclip and a second subclip;
• re-transcode the first portion of the of the first item of video content comprising the new subclips within the window, wherein a boundary between the first subclip and the second subclip define a location for the first breakpoint;
• identify existing segments of the first transcoded item of video content that can be used with the set of breakpoints without re-transcoding, wherein the existing segments of the first transcoded item of video content that can with the set of breakpoints are associated with corresponding existing playlists;
• generate new playlists for the new subclips;
• transmit the new playlists for the new subclips and the existing playlists to a client, wherein the client is configured to request content in accordance with the new playlists and the existing playlists;
• and
• stream the existing segments and the new subclips to the client in accordance with requests from the client.
