The nozzle electrode is configured to charge the cosmetic particles.

Abstract: Bitrate-adaptive segmentation is performed for transcoding a video stream uploaded to an online video platform for hosting and later playback to platform users. The video stream is segmented into chunks based on prediction-based bit costs determined for frames of the video stream rather than based on scene changes detected within the video stream. The bitrate-adaptive segmentation includes determining inter-prediction bit costs and intra-prediction bit costs for frames of the video stream based on information indicated within a pass log based on a first pass encoding of the video stream, determining chunk boundaries for segmenting the video stream into a chunk based on the inter-prediction bit costs and the intra-prediction bit costs for the frames, and transcoding the chunk to produce a transcoded video stream.

Abstract: A learning model is trained for rate-distortion behavior prediction against a corpus of a video hosting platform and used to determine optimal bitrate allocations for video data given video content complexity across the corpus of the video hosting platform. Complexity features of the video data are processed using the learning model to determine a rate-distortion cluster prediction for the video data, and transcoding parameters for transcoding the video data are selected based on that prediction. The rate-distortion clusters are modeled during the training of the learning model, such as based on rate-distortion curves of video data of the corpus of the video hosting platform and based on classifications of such video data. This approach minimizes total corpus egress and/or storage while further maintaining uniformity in the delivered quality of videos by the video hosting platform.

Abstract: A cloud-based gaming server renders a set of game frames at a first frame rate for a current client gaming session. An encoder of the server then determines whether the first frame rate is lower than a second frame rate associated with the encoder. In response to the first frame rate being lower, the encoder is configured to generate skip frames, with each skip frame indicating that a game frame of the set of game frames is to be repeated. The encoder also encodes the set of game frames to produce a set of encoded game frames and inserts one or more skip frames between two or more encoded game frames of the set of encoded game frames to produce a game stream. The server then packetizes the game stream and transmits the packetized game stream to a client system associated with the current client system.

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.

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: Methods and apparatus for associating a document with a database field value are disclosed. For example, a user of an electronic record management system may be viewing a document and/or metadata associated with a document on a primary display, such as a desktop computer display. In addition, the user may be viewing various database fields and/or potential values for those fields on a secondary display, such as a tablet device. The user can then select certain user interface objects, such as buttons, and/or perform certain predefined user gestures, such as a left swipe, on the secondary display. As a result, one or more database fields associated with the document are populated with one or more values. For example, the user may be executing an electronic document review application on a desktop computer while coding documents using a tablet device synchronized to the electronic document review application via the Internet.
