Ncast full HD intelligent recorder-player can realize multi-stream multi-picture recording mode, and can be converted into single-stream single-picture and single-stream multi-picture format later.
The following is a detailed comparison and introduction of several recording methods.
l Multi-stream multi-screen recording (multi-screen resource mode)
Multi-stream recording is a method of combining multiple video streams into one file. During recording and live broadcasting, each video stream or screen stream can be dragged arbitrarily or played in full screen. Moreover, any video stream or screen stream can be split or combined into a new file later. The advantage of the multi-stream recording and broadcasting method is that all the pictures on the scene can be saved.
The Ncast intelligent recording and broadcasting system can use the Media player player that comes with Microsoft or the NcastPlayer player that comes with the system to play. The NcastPlayer player is optimized for the Ncast system, and 2 + 1 split-screen mode is used for live broadcast and on-demand playback.
The picture above shows the effect when using NcastPlayer player to play files in three screens.
Since this player uses a dedicated multi-stream synchronous recording technology, each video window can be dragged with the mouse to switch between the windows, and you can also double-click the left mouse button to specify a window for full-screen playback. See below:
l Single stream single screen recording (movie mode)
Single-stream single-screen recording refers to switching among N video streams or screen streams, and using one of the streams to output as a file. In the education industry, because the excellent course recording files need to be submitted to the higher level management department (such as: the Ministry of Education) for evaluation, when opening this file, usually experts will not install a dedicated player, but use Microsoft's own Mediaplayer player. At this time, the advantages of the single-stream recording and broadcasting method are reflected. Due to the single-stream single-screen method, you can use the Mediaplayer player to open the live broadcast for viewing without installing any plug-ins or players. . Everything has its advantages and disadvantages. Because it is a single-stream single-screen recording and live broadcast method, users can only see one of the scenes when playing back files or watching live broadcasts, even if using the picture-in-picture method, the previous video It will still block the back part of the screen (for example, the front teacher video window blocks the computer PPT screen behind), and at the same time, the live material cannot be saved, only part of it can be saved.
Single window 4: 3 or 16: 9 display mode, support Windows Media Player to play directly. The picture can be switched between the video of the presenter, the video of the audience and the lecture (PPT).
l Single-stream multi-screen recording (out-of-picture mode)
Single-stream multi-picture mode refers to multi-picture splitting and merging among multiple video streams or screen streams, and can achieve N-three switching output, and the generated file is a single file with single window and multi-picture. The single-stream multi-screen recording and broadcasting method, also known as the picture-out-picture method, combines the advantages of multi-screen and multi-scene resource reservation in the multi-stream recording and broadcasting method and the advantages of using a universal player in the single-stream recording and broadcasting method , The recorded file is a single video file in widescreen mode. In a single video window, it is still presented in three-screen mode. The left side is two video windows and the right side is a main window. The video of the main window will be automatically switched by the system Or manual switching, the file generated by the recording supports a maximum resolution of 1920 * 1024, showing better classroom effects.
