In one embodiment, a method encodes a first set of segments of a media file based on a first bitrate range to generate a first set of encoded segments. It is then determined when an encoded segment for the first bitrate range includes a bitrate that satisfies a second bitrate range. When the encoded segment for the first bitrate range includes the bitrate that satisfies the second bitrate range, the method does not encode a segment in the first set of segments that corresponds to the encoded segment when the media file is encoded based on the second bitrate range to generate a second set of encoded segments for the second bitrate range. A first playlist for the first bitrate range is identified and a second playlist for the second bitrate range is identified. The second playlist also includes the encoded segment that was encoded for the first bitrate range.

Encoding optimization using bitrate range comparisons for encoded segments

In one embodiment, a method includes encoding a media file using a variable bitrate encoding algorithm based on a plurality of bitrate ranges to generate a set of encoded segments. For each bitrate range, an encoded segment for each segment of the media file is determined from the set of encoded segments based on a quality level of the encoded segment and each bitrate range. The method then identifies a playlist for each bitrate range including the encoded segment for each segment of the media file that was determined for each bitrate range. At least one playlist includes an encoded segment that was generated based on another bitrate range using the variable bitrate encoding algorithm.

Encoding optimization using quality level of encoded segments

In one embodiment, a method receiving a request for a media program from a user device. The method then determines a set of visual representations of captions for the media program and determines video information for the media program. Visual representations from the set of visual representations of captions are sent with the video information over a network to the user device where text for the captions has been pre-rendered in the sent visual representations before sending of the visual representations to the user device. Also, the user device is configured to directly render and overlay a visual representation of a caption from the visual representations over a portion of the video information without rendering of the text for caption on the portion of the video information at the user device.

Overlay of visual representations of captions on video

In one embodiment, a method includes storing a caption file including a set of visual representations of captions for a media program and a video file including video information for the media program. A server receives a request for the media program where the request is associated with a user device. The method determines the caption file and the video file for the media program based on the request. The server then sends visual representations of the captions from the caption file out of band with video information from the video file over a network to the user device. The user device is configured to overlay a visual representation of a caption over a portion of the video information.
