A method for generating a cyclic video sequence (SC), implemented by a data-processor (11). The method includes receiving a video sequence (S); determining a first singular point (P1) of the video sequence (S) in a first interval (11) of the sequence (S) and a second singular point (P2) of the video sequence (S) in a second interval (12) of the sequence (S). The first and second singular points (P1, P2) have a maximum similarity according to a given similarity criterion; then generating a connecting sequence (SR) between the image of the video sequence (S) corresponding to the second singular point (P2) and the image of the video sequence (S) corresponding to the first singular point (P1) by morphing then constructing the cyclic video sequence (SC) by concatenation of a fragment (S′) of the video sequence (S) extending from the first singular point (P1) to the second singular point (P2), and of the connecting sequence (SR).

A method for video editing using a mobile terminal and a remote computer is disclosed. A user selects a user video to edit using a mobile application of the mobile terminal. The user selects a visual effect and parameters of the visual effect using the mobile application. Subsequently, the mobile application provides a preview of the visual effect superimposed over the user video using a series of still images representing the visual effect. When the user confirms the preview, the mobile terminal generates a request for video editing and sends the request to a server. The request includes identification of the visual effect for combining the visual effect and the user video as confirmed by the preview. Based on the request from the mobile terminal, the server combines a video clip of the visual effect and the user video into a resulting video.

An enhanced concert audio experience arrangement includes a mixing console that receives a plurality of audio signals. Each audio signal is received from a respective microphone of a plurality of microphones. The mixing console mixes the audio signals into a plurality of combinations of audio signals. Each combination includes one or more selected ones of the audio signals. A transceiver is communicatively coupled to the mixing console and transmits air-borne signals including the combinations of audio signals. A mobile personal electronic device is communicatively coupled to the transceiver and enables a human user to select one of the combinations of audio signals transmitted by the transceiver, and listen to the selected combination of audio signals.

A system for playing media content items operates to provide smooth transitions between the media content items to continuously support a user's repetitive motion activity. The system can generate crossfade data containing information for transitions between media content items. The mix-in and mix-out points for the transitions are calculated to eliminate one or more portions of media content items that have lower musical energy than a majority portion of the items, and to maintain substantially consistent and/or stable musical energy (e.g., audio power or sound power) throughout the media content items including transitions therebetween.

An audio processor may process dissimilarly formatted digital audio signals and produce an analog output for reproduction by a transducer, such as a speaker. The audio processor may be, for example, a digital-to-analog converter (DAC) with multiple digital inputs and a single analog output. The audio processor may also include other components, such as processing components, filters, equalizers, amplifiers, and the like. The audio processor may process audio, such as high fidelity DSD audio and lower fidelity PCM audio, and combine the differently formatted data into a single output. During processing, the audio processor may manipulate the different audio signals, such as by ducking a music playback to allow a notification sound to be played.

A system of playing media content items determines transitions between pairs of media content items by determining desirable locations in which transitions across the pairs of media content items occur. The system uses a plurality of track features of media content items and determines such track features of each media content item associated with each of transition point candidates, such as beat positions, of that media content item. The system determines similarity in the plurality of track features between the transition point candidates of a first media content item and the transition point candidates for a second media content item being played subsequent to the first media content item. The transition points or portions of the first and second media content items are selected from the transition point candidates for the first and second media content items based on the similarity results.
