Retiming digital videos utilizing machine learning and temporally varying speeds
This disclosure describes one or more implementations of systems, non-transitory computer-readable media, and methods that generate a temporally remapped video that satisfies a desired target duration while preserving natural video dynamics. In certain instances, the disclosed systems utilize a playback speed prediction machine-learning model that recognizes and localizes temporally varying changes in video playback speed to re-time a digital video with varying frame-change speeds. For instance, to re-time the digital video, the disclosed systems utilize the playback speed prediction machine-learning model to infer the slowness of individual video frames. Subsequently, in certain embodiments, the disclosed systems determine, from frames of a digital video, a temporal frame sub-sampling that is consistent with the slowness predictions and fit within a target video duration. In certain implementations, the disclosed systems utilize the temporal frame sub-sampling to generate a speed varying digital video that preserves natural video dynamics while fitting the target video duration.
Camera system using stabilizing gimbal
Disclosed is an electronic gimbal with camera and mounting configuration. The gimbal can include an inertial measurement unit which can sense the orientation of the camera and three electronic motors which can manipulate the orientation of the camera. The gimbal can be removably coupled to a variety of mount platforms, such as an aerial vehicle, a handheld grip, or a rotating platform. Moreover, a camera can be removably coupled to the gimbal and can be held in a removable camera frame. Also disclosed is a system for allowing the platform, to which the gimbal is mounted, to control settings of the camera or to trigger actions on the camera, such as taking a picture, or initiating the recording of a video. The gimbal can also provide a connection between the camera and the mount platform, such that the mount platform receives images and video content from the camera.
Method for recording multimedia file and electronic device thereof
This present disclosure provides a method for recording a multimedia file using an electronic device. The method includes previewing a scene comprising a plurality of objects in a field of view of a camera of the electronic device and detecting at least one of a shape event and a sound event associated with at least one object from the plurality of objects in the scene. Further, the method includes determining at least one of a recoding mode and an effect for the at least one object based on at least of the sound event and the shape event and applying at least one of the recording mode and the effect. The method also includes recording the multimedia file comprising the at least one object in at least one of the recording mode video and the effect and storing the multimedia file.

PLAYBACK METHODS FOR CONTRAST-ENHANCED ULTRASOUND MOVIE FILE AND ULTRASOUND MOVIE FILE AND ULTRASOUND APPARATUS
Disclosed are a method for playing a CEUS movie file, an ultrasound movie file, and ultrasound apparatus. The method comprises: receiving a playing instruction for the movie file which is a dynamic data of generated by ultrasound echoes returned from a target tissue to which ultrasound waves are transmitted by a probe of an ultrasound apparatus; determining an imaging frame rate of the ultrasound images; determining a playback frame rate of the movie file according to the imaging frame rate negatively correlated with the playback frame rate; and playing the movie file with the playback frame rate. By using the playback frame rate which is negatively correlated with the imaging frame rate to play movie files, the movie files with low frame rate can be played more smoothly and the movie files with high frame rate can be played in line with the look and feel of the human eye.
COMPUTER IMPLEMENTED METHOD, DEVICE AND COMPUTER PROGRAM PRODUCT FOR SETTING A PLAYBACK SPEED OF MEDIA CONTENT COMPRISING AUDIO
A computer implemented method for setting a playback speed of media content comprising audio, the media content having a defined normal playback speed, the method comprising: receiving an indication that the media content is to be played at a speed different from the normal playback speed of the media content, analysing the audio for determining a type of audio; and determining a playback speed different from the normal playback speed depending on the determined type of audio, and setting the playback speed of the media content to the determined playback speed.
CAMERA USER INTERFACE WITH RECORDING SPACE MANAGEMENT
The present disclosure generally relates to user interfaces for managing recording space for visual media. A computer system displays a camera preview and a recording space affordance that, when selected, initiates performing an operation associated with recording space available for recording media captured by the one or more cameras.

TECHNIQUES FOR ENHANCING SLOW MOTION RECORDING
Methods, systems, and devices for enhancing scene statistics for slow motion recording are described. The method may include capturing from a first sensor of the device a first set of video frames at a first frame rate, capturing from a second sensor of the device a second set of video frames at a second frame rate different from the first frame rate, analyzing an aspect of the first set of video frames in relation to an aspect of the second set of video frames, generating a mapped set of video frames based on the analyzing and a mapping of the aspect of the first set of video frames to the aspect of the second set of video frames, and storing the mapped set of video frames on a display of the device.
Advanced trick-play modes for streaming video
Enhanced trick-play modes for video content that is being streamed to a client from a server are described. In an embodiment, the enhanced trick-play modes are provided with relatively low latency and high quality using trick-play optimization techniques for a streaming environment, avoiding the need to stream the entire contents of the portions through which the viewer is fast forwarding. By employing sophisticated selection criteria of which parts of the content to download at what time, the quality of the playback experience is improved versus that which would conventionally be possible when using a simple sequential frame data download. The streaming client maintains a cache of nearby significant frames, such as nearby key frames, in forward and/or reverse directions of the current playback position, without having to download the entire portions of the video stream in which the significant frames reside. The trick-play modes utilize these frames.
