The method includes: acquiring a multimedia file and an operation information contained in each editing track of a plurality of editing tracks, wherein the operation information is acquired to edit the multimedia file; detecting a multimedia file frame contained in the each editing track at a current time in a case of editing the multimedia file in a chronological order; editing the multimedia file frame contained in the each editing track at the current time by using the operation information associated with the multimedia file frame, so as to obtain an edited file frame contained in the each editing track at the current time; and performing an encoding synthesis on the edited file frame contained in the each editing track at the current time. ## Claims ### Claim 1 A method of editing a multimedia file, comprising: acquiring a multimedia file and an operation information contained in each editing track of a plurality of editing tracks, wherein the operation information is acquired to edit the multimedia file; detecting a multimedia file frame contained in the each editing track at a current time in a case of editing the multimedia file in a chronological order; editing the multimedia file frame contained in the each editing track at the current time by using the operation information associated with the multimedia file frame, so as to obtain an edited file frame contained in the each editing track at the current time; and performing an encoding synthesis on the edited file frame contained in the each editing track at the current time. ### Claim 2 (depends on 1) The method of claim 1, wherein the detecting a multimedia file frame contained in the each editing track at a current time in a case of editing the multimedia file in a chronological order comprises: detecting whether a multimedia file frame to be edited is contained in the each editing track of the plurality of editing tracks at the current time or not, in the case of editing the multimedia file in the chronological order; and obtaining the multimedia file frame to be edited contained in the each editing track at the current time, based on a result of detection. ### Claim 3 (depends on 1) The method of claim 1, wherein the plurality of editing tracks comprise at least two first editing tracks of the same track type, and the method further comprises: determining a priority of each first editing track of the at least two first editing tracks; and performing a superimposing synthesis on the edited file frame contained in the each first editing track at the current time according to the priority of the each first editing track, prior to the performing the encoding synthesis on the edited file frame contained in the each editing track at the current time. ### Claim 4 (depends on 3) The method of claim 3, wherein the at least two first editing tracks are audio tracks, the edited file frame contains an edited audio frame, and the performing a superimposing synthesis on the edited file frame contained in the each first editing track at the current time comprises: performing a superposing calculation on a waveform of the edited audio frame contained in the each first editing track at the current time, so as to form an audio waveform. ### Claim 5 (depends on 1) The method of claim 1, wherein the performing an encoding synthesis on the edited file frame contained in the each editing track at the current time comprises: encoding the edited file frame contained in the each editing track at the current time by using an encoder. ### Claim 6 (depends on 1) The method of claim 1, further comprising: generating an encoding synthesis progress subsequent to the performing the encoding synthesis on the edited file frame contained in the each editing track at the current time. ### Claim 7 (depends on 6) The method of claim 6, further comprising: positioning an edition failure according to the encoding synthesis progress in response to a presence of the edition failure, during the editing the multimedia file in the chronological order. ### Claim 8 (depends on 7) The method of claim 7, wherein the positioning an edition failure according to the encoding synthesis progress comprises: determining a multimedia file frame containing the edition failure according to the encoding synthesis progress. ### Claim 9 (depends on 6) The method of claim 6, wherein the generating an encoding synthesis progress comprises: acquiring a playback time information for the edited file frame at the current time; and generating the encoding synthesis progress according to the playback time information. ### Claim 10 (depends on 1) The method of claim 1, wherein the editing the multimedia file frame contained in the each editing track at the current time by using the operation information associated with the multimedia file frame comprises: editing the multimedia file frame contained in the each editing track at the current time in parallel by using the operation information associated with the multimedia file frame. ### Claim 11 (depends on 1) The method of claim 1, wherein the plurality of editing tracks comprise at least one of a video track, an audio track, a subtitle track, and a mapping track. ### Claim 12 (depends on 1) The method of claim 1, wherein the operation information contains at least one of a filter information, a transition information, a multiple speed information, a clipping information, a rotation information, an image brightness information, an image chroma information, an image saturation information, an image display size, an image display duration, and image display coordinates. ### Claim 13 An electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor, and the instructions, when executed by the at least one processor, cause the at least one processor to implement operations of editing a multimedia file, comprising: acquiring a multimedia file and an operation information contained in each editing track of a plurality of editing tracks, wherein the operation information is acquired to edit the multimedia file; detecting a multimedia file frame contained in the each editing track at a current time in a case of editing the multimedia file in a chronological order; editing the multimedia file frame contained in the each editing track at the current time by using the operation information associated with the multimedia file frame, so as to obtain an edited file frame contained in the each editing track at the current time; and performing an encoding synthesis on the edited file frame contained in the each editing track at the current time. ### Claim 14 A non-transitory computer-readable storage medium having computer instructions stored thereon, wherein the computer instructions allow a computer to implement operations of editing a multimedia file, comprising: acquiring a multimedia file and an operation information contained in each editing track of a plurality of editing tracks, wherein the operation information is acquired to edit the multimedia file; detecting a multimedia file frame contained in the each editing track at a current time in a case of editing the multimedia file in a chronological order; editing the multimedia file frame contained in the each editing track at the current time by using the operation information associated with the multimedia file frame, so as to obtain an edited file frame contained in the each editing track at the current time; and performing an encoding synthesis on the edited file frame contained in the each editing track at the current time.
