Content adaptive micro encoding optimization for video

A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a computing device, cause the computing device to be operable for:

• analyzing flagged frames from a plurality of frames in an encoding of a video to form a cluster of frames, wherein the cluster includes a plurality of flagged frames;
• determining draft micro-chunk boundaries for the cluster of a first start frame and a first end frame in the encoding that includes the cluster;
• searching in a first search range before the first start frame and a second search range after the first end frame for a second start frame in the first search range and a second end frame in the second search range, wherein the second start frame and the second end frame form a micro-chunk;
• analyzing multiple frames based on the second start frame and the second end frame to determine content characteristics for the micro-chunk;
• determining an encoding parameter set for the micro-chunk formed by the second start frame and the second end frame based on mapping the content characteristics of the micro-chunk to the encoding parameter set;
• and
• using the encoding parameter set to encode the plurality of frames in the micro-chunk for insertion in the encoding of the video.

An apparatus comprising:

• one or more computer processors;
• and
• a computer-readable storage medium comprising instructions for controlling the one or more computer processors to be operable for:
• analyzing flagged frames from a plurality of frames in an encoding of a video to form a cluster of frames, wherein the cluster includes a plurality of flagged frames;
• determining draft micro-chunk boundaries for the cluster of a first start frame and a first end frame in the encoding that includes the cluster;
• searching in a first search range before the first start frame and a second search range after the first end frame for a second start frame in the first search range and a second end frame in the second search range, wherein the second start frame and the second end frame form a micro-chunk;
• analyzing multiple frames based on the second start frame and the second end frame to determine content characteristics for the micro-chunk;
• determining an encoding parameter set for the micro-chunk formed by the second start frame and the second end frame based on mapping the content characteristics of the micro-chunk to the encoding parameter set;
• and
• using the encoding parameter set to encode the plurality of frames in the micro-chunk for insertion in the encoding of the video.
