Abstract: Decoding a current block includes obtaining at least one of a maximum motion vector (MV) precision or a minimum MV precision for a group of blocks. The group of blocks includes the current block. A block-level MV precision for decoding the current block is obtained. The block-level MV precision is such that it is limited by the at least one of the maximum MV precision or the minimum MV precision. An MV for the current block is decoded using the block-level MV precision. A prediction block is obtained for the block using the MV.

Abstract: A system and method for compressing and restoring data using hierarchical autoencoders and Lorentzian autoencoders for video processing. For general data, the system employs hierarchical autoencoders operating at multiple scales. For video data, Lorentzian autoencoders preserve three-dimensional tensor structure where spatial and temporal relationships remain intact throughout compression and decompression. A correlation network, trained on cross-correlated data sets, enhances restoration by leveraging relationships between compressed representations, recovering information lost during compression. The Lorentzian approach enables advanced video features including temporal prediction and infinite zoom, where users can examine regions beyond original resolution with synthesized yet plausible details.

Abstract: A computer implemented method for algorithmically editing digital video content is disclosed. A video file containing source video is processed to extract metadata. Label taxonomies are applied to extracted metadata. The labelled metadata is processed to identify higher-level labels. Identified higher-level labels are stored as additional metadata associated with the video file.

Responsive to determining a clip presentation trigger on a viewer device, a clip selection algorithm is implemented that applies engagement data and metadata for the candidate video clips to select one of the stored candidate video clips. The engagement data is representative of one or more engagement metrics recorded for at least one of the stored candidate video clips. The selected video clip is presented to one or more viewers via corresponding viewer devices.

Abstract: A camera device comprises an image sensor, a first moving module and two groups of second moving modules. The first moving module is connected to the image sensor. The first moving module is activated to move the image sensor linearly along a first axis. The second moving module is connected to the image sensor. The second moving module is activated to move the image sensor linearly along a second axis, which intersects with the first axis. The two groups of second moving modules are activated simultaneously to rotate the image sensor around a third axis, which is orthogonal to the first and second axes, respectively. The image sensor compensates for the image by linear movement in the direction of the first axis and the second axis and can also compensate for the image by rotation in the direction of the third axis to achieve three-axis image stabilization.
