Abstract: Videos associated with video resolutions may be received. A first bitrate for each of the video resolutions may be identified based on a first bitrate point associated with the videos where a quality of the videos at a first video resolution that is upscaled to a second video resolution is better than a quality of the videos at the second video resolution at bitrates below the first bitrate point. The upscaling of the first video resolution may correspond to converting the videos from the first video resolution to the second video resolution at a client device. The identified corresponding first bitrate may be assigned to each of the video resolutions.

Abstract: A request for a video may be received from a client device. A determination whether to transmit the video at a first video resolution or a second video resolution based on a quality of the video at the first video resolution when converted to the second video resolution at the client device may be made. The video may be transmitted to the client device at the determined first video resolution or the second video resolution.
