Problems solved by technology
[0007] The purpose of the present invention is to solve the problem that the non-linear editing products currently on the market are all stand-alone, and the hardware capability of the stand-alone non-linear editing system cannot meet the user's editing requirements for 8K video. Segmented clustering is a method for realizing large-format multi-layer real-time editing. Multiple machines are used to form a cluster, and the heavy computing tasks of multi-layer large-format video editing are split into different machines for processing by inter-frame segmentation. Use very high-speed network technology to realize data transmission, so that users can realize free and smooth multi-layer large-format video real-time editing. The operation experience is not much different from high-definition editing, and realizes unlimited formats, unlimited layers, and unlimited frame rates. free editor

Embodiment 1
[0035] Such as figure 1 As shown, this embodiment provides a method for realizing large-format multi-layer real-time editing based on inter-frame segmentation clustering, including the following steps:
[0036] S1: Traditional network networking methods, such as Ethernet, whether it is 10GE, 25GE, or 40GE, cannot meet the transmission requirements of 8K data. Therefore, this embodiment adopts the InfiniBand network, and its core technology is RDMA (Remote DirectMemory Access). It can greatly shorten the delay and increase the bandwidth. In this embodiment, multiple machines are used to form an InfiniBand network cluster, and a 100Gbps InfiniBand switch is used to realize the data transmission of multiple machines. Each machine is configured with one or two InfiniBand network cards, so each machine The incoming and outgoing bandwidth can reach 100Gbps or 200Gbps, which can meet the low-latency transmission of large-format baseband data. Among them, multiple machines forming an ...

The invention discloses a method for realizing large-format multi-layer real-time editing based on inter-frame segmentation, and relates to the technical field of video editing. The invention includes the following steps: S1: using multiple machines to form an InfiniBand network cluster, each machine Configure the InfiniBand network card; S2: Set each machine to have the same timeline information, so that the timeline data structures of all machines are synchronized; S3: The input video file is divided between frames, and the divided video frames are set according to the settings. The predetermined distribution rule is distributed to multiple machines for parallel decoding and rendering processing, and rendering data is obtained; S4: Buffer and sort the rendering data of each frame to form a correct playback sequence, and complete the editing. The present invention uses multiple machines to form a cluster, Using the method of inter-frame segmentation, the heavy computing tasks of multi-layer large-format video editing are divided into different machines for processing, realizing free editing with unlimited format, unlimited number of layers, and unlimited frame rate.
Description
technical field [0001] The invention relates to the technical field of video editing, and more specifically relates to a method for realizing large-format multi-layer real-time editing based on inter-frame segmentation clustering. Background technique [0002] At present, we have entered the era of ultra-high-definition large-format video. Large-format video has massive data. Taking 8K as an example, a nonlinear editing system needs to edit a layer of 8K4:2:2 10bit50P video, and it needs to process more than 50Gbit of data per second, and These processes include very complex operations such as decoding and rendering. However, the hardware capability of the current stand-alone nonlinear editing system is completely insufficient for editing 8K video, which is specifically reflected in the following aspects: [0003] 1. The CPU decoding ability is insufficient. At present, Intel's high-end dual-channel Xeon Gold processor can only decode 8K video in real-time for one layer, no...
