Use under each application scenarios under operation flow to video editing.
Detailed description of the invention
Fig. 1 is multi-terminal video collaborative editing structural schematic diagram；
Fig. 2 is the flow chart for generating project file；
Fig. 3 is project file locking flow figure.
Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art more fully understand technical solution of the present invention
Applying example, the present invention is described in further detail.
A kind of multi-terminal video collaborative editing system, including common NLE system and non-volume terminal, the common non-volume system
System includes non-volume material database, further includes backstage transcoding center, the transcoding center identification file format automatically generates extra code rate
File format.
As shown in Figure 1, the non-volume material database include the high code rate stored in file format area being arranged in Intranet, setting exist
The middle code rate stored in file format area and low bit- rate stored in file format area of outer net；The non-volume terminal include the non-volume terminal of BS,
The non-volume terminal of mobile phone, the non-volume terminal of PC, BS is non-to compile the non-low bit- rate file compiled in material database outer net of terminal access, the non-volume of mobile phone eventually
Access non-middle code rate file, the PC for compiling material database outer net in end is non-to compile the non-high code rate file for compiling material database outer net of terminal access.Number
There is the non-project file for compiling terminal of compatible various types according to middle storage.
A kind of multi-terminal video synergic editing method, including new construction or opening engineering step.Wherein, as shown in Fig. 2,
The new construction, including following sub-step: S1: non-volume terminal is newly-built, saves project file；S2: project file is carried out
Locking；S3: it selects to be applicable in material format in material database, and is bound；S4: editing files are submitted after the completion and save text
