Abstract
Among other things, embodiments of the present disclosure improve the functionality of electronic messaging and imaging software and systems by automating the client-side transcoding of video data based on content. For example, an appropriate transcoding configuration can be selected for video data having complex motion or textures. Accordingly, video quality can be improve when complex motions or textures are present.
Claims20
A system comprising:
- a processor;
- a user interface coupled to the processor, the user interface comprising an image capture device;
- and
- memory coupled to the processor and storing instructions that, when executed by the processor, cause the system to perform operations comprising:
- determining a complexity within a field of view of an image capture device that captured video data;
- and
- generating, based on the determined complexity and the video data, transcoded video data by selecting a transcoding configuration that applies a bitrate to the video data, the transcoding configuration selected from a plurality of transcoding configurations of varying bitrates, wherein the bitrate applied to the transcoded video is selected to correspond to a video quality metric, based on predefined mappings between at least one video quality metric and the transcoding configuration.
A computer-implemented method comprising:
- determining a complexity within a field of view of an image capture device that captured video data;
- and
- generating, based on the determined complexity and the video data, transcoded video data by selecting a transcoding configuration that applies a bitrate to the video data, the transcoding configuration selected from a plurality of transcoding configurations of varying bitrates, wherein the bitrate applied to the transcoded video is selected to correspond to a video quality metric, based on predefined mappings between at least one video quality metric and the transcoding configuration.
A non-transitory computer-readable medium storing instructions that, when executed by a computer system, cause the computer system to perform operations comprising:
- determining a complexity within a field of view of an image capture device that captured video data;
- and
- generating, based on the determined complexity and the video data, transcoded video data by selecting a transcoding configuration that applies a bitrate to the video data, the transcoding configuration selected from a plurality of transcoding configurations of varying bitrates, wherein the bitrate applied to the transcoded video is selected to correspond to a video quality metric, based on predefined mappings between at least one video quality metric and the transcoding configuration.
