In some instances, methods, means, components and circuits that are well known to those skilled in the art are not described in detail in order to emphasize the subject matter of the disclosure.

FIG. 1 shows a flowchart of a method for recommending film and television soundtrack authors according to an embodiment of the present disclosure. As shown in Figure 1, the method includes:

Step S100: Determine the matching degree between the first film and television attribute information of the first film and television segment to be soundtracked and a plurality of second film and television attribute information. The plurality of second film and television attribute information corresponds to a plurality of preset first music pieces. Film and television attribute information;

Step S200: Determine third film and television attribute information from the plurality of second film and television attribute information, and the third film and television attribute information matches the first film and television attribute information among the plurality of second film and television attribute information. At least one film and television attribute information with the highest degree;

Step S300: Determine the author of the second piece of music corresponding to the third film and television attribute information as the soundtrack author of the first film and television clip.

According to embodiments of the present disclosure, based on the matching degree between the film and television attribute information of the film and television fragment to be soundtracked and the film and television attribute information corresponding to multiple preset musical compositions, the film and television fragment to be soundtracked can be selected from the plurality of musical compositions with the highest matching degree At least one piece of music, and the author of the piece is determined as the soundtrack author of the film and television clip, so that the soundtrack author can be recommended for the film and television clip according to the matching degree of the film and television attribute information, improving the pertinence and accuracy of the soundtrack author recommendation, and thus making it possible to Improve the production efficiency of the entire film and television works.

In a possible implementation, the film and television works described in the embodiments of the present disclosure may refer to a series of pictures shot on a certain substance (such as film, storage media, etc.) with or without accompanying sound. Works composed of, and projected and played with the help of appropriate devices (such as players), may include film works and works created using methods similar to filmmaking (such as TV series, video works, etc.). This disclosure does not limit the specific content of film and television works.

In one possible implementation, when determining the soundtrack author of a film and television work, the film and television work can be divided into multiple film and television clips, and the soundtrack author can be recommended for each film and television clip to be soundtracked, and then the soundtrack author can be recommended The number of recommendations, the weight of each film and television clip, etc., determine one or more soundtrack authors of the film and television work. This disclosure does not limit the method and specific number of soundtrack authors for film and television works.

In one possible implementation, before determining the composer of the first film and television clip to be scored, a plurality of preset first music pieces and second film and television attribute information corresponding to the first music pieces may be determined first. The recommended methods by film and television soundtrack authors may also include:

Establish a film and television music library, the film and television music library includes a plurality of music-film pairs, each music-film pair includes a first music and a second film and television segment corresponding to the first music;

Determine the first fitting coefficient according to the preset fitting model, the music attribute information of the first piece of music in the plurality of music-film pairs and the fourth film attribute information of the second film and television clip;

According to the fitting model, the first fitting coefficient and the music attribute information of each first piece of music, the second film and television attribute information corresponding to each first piece of music is determined respectively.

In one possible implementation, multiple soundtrack film and television clips can be selected by selecting classic soundtracks or classic film and television clips, or a combination of the two; and then based on the multiple soundtrack film and television clips, a music-film pair can be created. Film and television music library. Each music-movie pair includes a first music piece and a second video clip corresponding to the first music piece.

For example, when establishing a film and television music library, multiple classic soundtrack film and television clips can be selected from multiple released film and television works; and then multiple music-film pairs can be determined based on the multiple soundtrack film and television clips: for any For the soundtrack film and television clip, the soundtrack of the soundtrack film and television clip can be determined as the first music piece of the music piece-film and television pair, and the soundtrack film and television clip can be determined as the second film and television clip in the music piece-film and television pair corresponding to the first music piece. For example, a music-film pair can be determined based on the soundtrack film and television clip of "XX Earth" from 2:39 to 6:52: the soundtrack of the film and television clip "Global XX and "XX Earth Project"" can be determined as the music-film pair As the first piece of music in the pair, the film and television clip from 2:39 to 6:52 of "XX Earth" is determined to be the second film and television clip in the music-film pairing corresponding to the first piece of music.

In one possible implementation, after the film and television music library is established, the music attribute information of the first music piece and the fourth film and television attribute information of the second film and television segment in each music-film pair can be determined respectively.

In a possible implementation, the music attribute information of the first music piece may include the rhythm, main mode, harmony progression type, orchestration, mood type, style type, and sound-picture relationship of the first music piece.

In a possible implementation, the rhythm of the first piece of music may include beat and speed. Among them, the beat refers to the total length of the notes in each section of the first piece of music, which can be represented by the time signature, recorded as N/M (where N represents the number of beats in each section, and M represents the basic time value of the beat), for example , 2/4, 3/4, 4/4, 6/8, 7/8, 9/8, etc.; the speed can be expressed by BPM (Beat Per Minute), for example, BPM=90.

In a possible implementation, when determining the rhythm of the first piece of music, all different rhythms that appear in the first piece of music can be analyzed, and the duration from the appearance to the end is less than or equal to the first preset duration (for example, 4 (the duration of the measure) is discarded, and other rhythms are determined as the rhythm of the first piece of music.

Among them, the duration of each section can be determined by the beat and speed of the first piece of music. For example, the duration t of each section can be determined by the following formula (1):

For example, the rhythm of the first piece of music "Global XX and "XX Earth Plan"" includes beat 4/4 and speed BPM=90.

It should be understood that those skilled in the art can determine its rhythm (including beat and speed) according to the score of the first piece of music and the actual situation, and this disclosure does not limit this.

In a possible implementation, mode analysis can be performed on the first piece of music according to a preset mode type to determine multiple main modes of the first piece of music. Among them, the preset mode types may include: natural major (i.e., Ionian mode, referred to as C major), natural minor (i.e., Aeolian mode), harmonic minor, melodic minor, and Chinese pentatonic mode ( Gong, Shang, Jiao, Zheng, Yu), other church melodies (including other church melodies except Ionian and Aeolian modes), other modes (including Japanese folk modes, Great Phrygian scale , blues, various six-tonal modes, atonal and other modes).

In one possible implementation, when performing a mode analysis on the first piece of music, its initial mode and the mode confirmed after the modulation can be determined as the main mode of the first piece of music. Among them, the mode after transposition can be confirmed in the following way: only when an established mode is explicitly abandoned (for example, after exceeding the second preset duration), another mode is re-clarified and concluded by its harmony. Only when there is a modulation is considered to have occurred. Any other non-natural sounds that do not belong to the scale of the mode are considered to be temporary out of tune (or appear in a certain area of the mode), not modulations. For example, the mode in which the duration from the appearance of a new mode of each modulation to the end of the mode is less than or equal to 5% of the duration of the entire music or the duration of 2 measures can be discarded, and the new modes of other modulations can be regarded as confirmed after the modulation. debug. Those skilled in the art can confirm the modulation after transposition according to actual conditions, and this disclosure does not limit this.

For example, for the first piece of music "Global XX and "XX Earth Plan"", after analysis, the first piece of music from 0:00 to 1:40 is in B natural minor, and from 1:40 to the end of the music is in C natural minor, then, the The main mode of the first piece of music is natural minor.

In a possible implementation, the harmony progression type of the first piece of music may be determined based on the complexity of the harmony progression of the first piece of music. Among them, the complexity of the harmony may include the frequency of harmonic transformation, the radical degree of out-of-key (that is, the distance between the area where the harmony reaches and the natural form of the mode) and the frequency of out-of-key. Harmony progression types can include conservative, neutral, or aggressive.

In a possible implementation, the frequency of harmonic transformation, the radical degree of off-keying, and the frequency of off-keying can be divided into three levels: 0, 1, and 2.

Wherein, the frequency level of the harmony transformation of the first music piece may be determined based on the average harmony transformation frequency of the first music piece. For example, when the average harmony change frequency of the first piece of music is less than or equal to 1 time per measure, the frequency level of the harmony change is 0; when the average harmony change frequency of the first piece of music is greater than or equal to 2 times per measure , the frequency level of the harmony change is 2; in other cases, the frequency level of the harmony change of the first piece of music is 1.

In a possible implementation, the level of the radical degree of out-of-key of the first piece of music can be determined in the following way: in the first piece of music, only natural chords and heavy dominant chords of the current key are used (for example: II , II7, II9, #IVdim7, etc.), IVm in a major key (i.e. harmonic major), the radical degree of off-key is 0; the chords used in the first piece of music not only include chords with a 0 level, but also When there are secondary dominant chords from church modes and artificial augmented thirds, diminished thirds, and half-diminished seventh chords based on the natural scale of the key, the degree of radicalness of the off-key is 1; in the first piece of music, the above mentioned When there are other chords besides the chord (such as other chords in the minor subordinate field, various wandering chords, etc.), the degree of radicalness of the off-key is 2.

In a possible implementation, the frequency level of the out-of-keyness of the first piece of music can be determined in the following manner: in the harmony sequence of the harmonic progression of the first piece of music, the proportion of unnatural chords is greater than Or equal to the first preset proportion (for example, 30%), the frequency level of its off-keyness is 2; the proportion of non-natural chords in the harmony sequence of the harmonic progression of the first piece of music is less than or equal to When the second preset proportion (for example, 5%) is used, the off-key frequency level is 0, where the second preset proportion is smaller than the first preset proportion; in other cases, the off-key frequency of the first piece of music is 0. The level of frequency of tuning is 2.

After determining the frequency level of harmonic changes, the radical level of off-keyness, and the frequency level of off-keyness of the first piece of music, the harmonic progression of the first piece of music can be determined based on the sum of the three levels. type. For example, when the sum of the three levels is 0, 1, and 2, the harmony progression type of the first piece of music is conservative; when the sum of the three levels is 3, the harmony progression type of the first piece of music is neutral; When the sum of the three levels is 4, 5, or 6, the harmony progression type of the first piece is radical.

For example, after analysis, the frequency of harmonic changes in the first piece "Global XX and "XX Earth Plan" is rated 0; the degree of radical off-keyness is rated 2 because it uses a Naples 6 at 1:31 Chordal harmony (bII) is used to assist the progression of modulation; the frequency of out-of-tune levels is 0. The sum of the three levels is 2, and therefore, the harmony progression type of this first piece of music can be determined to be conservative.

It should be understood that those skilled in the art can determine the frequency of harmonic transformation, the radical degree of off-key, and the specific levels of the frequency of off-key according to actual conditions, and this disclosure does not limit this.

In a possible implementation, the instrument arrangement of the first piece of music can be analyzed according to the preset instrument type, and at least one orchestration of the first piece of music can be determined. Among them, the preset instrument types may include: Accordion, Bass, Brass Ensemble, Trumpet, Trombone, Horn, Tuba ), Timpani (Timpani), Bell (Bell), other percussion instruments (Mallett), woodwind group (Wood), jazz drum (DrumSet), acoustic guitar (A.Guitar), electric guitar (E.Guitar), harp ( Harp), electric piano (E.Piano), piano (Piano), organ (Organ), string ensemble (String Ensemble), violin (Violin), violin solo (ViolinSolo), cello solo (VioloncelloSolo), synthesizer ( Synth), Vocals (Vocals), Saxophone, Oboe, Flute, Clarinet, Bassoon and other instruments.

For example, after analyzing the instrument arrangement of the first piece of music "Global XX and "XX Earth Plan"", it was determined that its orchestration includes string ensemble, brass ensemble, piano and timpani.

In a possible implementation, the emotional type of the first piece of music can be determined based on the preset emotional type and the mode, orchestration, rhythm, etc. of the first piece of music. Among them, the preset emotion types may include sadness, calmness, horror, excitement, and joy.

For example, for the first piece of music "Global XX and "XX Earth Plan"", the emotion type can be determined to be "excited" based on the preset emotion type and the mode and rhythm of the first piece of music.

In a possible implementation, the style of the first piece of music can be determined according to a preset style type. The preset style types may include symphony, rock, jazz, rap, electronic music, new age music, vocal, pop, folk, and cover.

In a possible implementation, the sound-visual relationship between the first music and the second video clip can also be determined based on the picture relationship between the first music and the second video clip in the music-movie pair. Among them, the relationship between sound and picture can include parallelism between sound and picture, synchronization between sound and picture, and counterpoint between sound and picture. Parallel sound and picture means that the first music and the picture of the second film and television clip are not related, and they exist independently and do not affect each other; synchronization of sound and picture means that the first music and the picture of the second film and television clip are closely integrated, and the emotions of the two are maintained. consistent, and the rhythm remains synchronized; counterpoint between music and video means that the mood, rhythm, etc. of the first piece of music are inconsistent or opposite to the picture of the second film and television clip.

In a possible implementation manner, the fourth film and television attribute information of the second film and television clip may include the film and television type, emotional type, plot function and shooting technique of the second film and television clip.

Among them, the film and television genre of the second film and television clip can be one or more. For example, "XX Earth" belongs to the science fiction genre, and "War X" belongs to the action, war, and military genre.

In a possible implementation, all film and television genres of film and television works can be preset. For example, all film and television genres of film and television works can include history, war, romance, science fiction, military, action, comedy, tragedy, horror, suspense, and ethics. ; and then determine the film and television type of the second film and television clip based on the plot, scene and other actual conditions of the second film and television clip. Those skilled in the art can preset all film and television types of film and television works according to actual conditions, and this disclosure does not limit this.

In a possible implementation, at least one emotion type of the second film and television clip can be determined based on a preset emotion type, the plot, scene, etc. of the second film and television clip. Among them, the preset emotion types may include sadness, calmness, horror, excitement, and joy.

For example, the film and television clips from 2:39 to 6:52 of "XX Earth" tell the story of countries forming a coalition government to jointly resist the coming global disaster, and formulating plans for "navigators" and "migration to underground cities". According to the plot, it can be determined that the emotional type of the film and television clips from 2:39 to 6:52 of "XX Earth" is "calm".

For another example, in the film and television clips from 49:30 to 53:32 of "XX Earth", the tense atmosphere before the grandfather's death can correspond to the "thriller" emotion. After the grandfather's death, the protagonist and others are sad and sad at the loss of their loved ones, which can correspond to the "sad" emotion. It can be determined that the emotional types of the film and television clips from 49:30 to 53:32 of "XX Earth" are "thriller" and "sadness".

For example, in the film and television clip of "XX Earth" from 1:17:55 to 1:21:53, the protagonist and others discovered a way to save the earth and made a plan. The corresponding emotion is "excited". Therefore, it can be determined that "XX Earth" 》The emotion type of the film and television clips from 1:17:55 to 1:21:53 is "excited".

It should be understood that those skilled in the art can determine the specific emotional type of the second video clip according to actual conditions, and this disclosure does not limit this.

In a possible implementation method, the plot role of the second video clip in the film and television work can be determined based on the preset plot role, the plot, scene, etc. of the second video clip. Among them, the preset plot functions can include: clues or promoting the development of the storyline, setting up suspense to arouse the audience's interest, making the plot exciting and exciting, echoing the plot of the previous film and television clip, foreshadowing or foreshadowing the development of the subsequent plot, Explain the environment in which the characters in the play move, depict the characters' personalities, express the main theme or deepen the theme, and leave sufficient space for the audience's imagination. Those skilled in the art can preset the plot functions of film and television clips in film and television works according to actual conditions, and this disclosure does not limit this.

For example, the film and television clips from 2:39 to 6:52 of "XX Earth" explain the whole story of the Wandering Earth Project, that is, the earth is about to suffer the catastrophe of being annihilated by the sun. Countries formed a coalition government and decided to implement the Wandering Earth Project and use "Goodbye, Solar System" is said in more than a dozen languages. At the same time, the story of the protagonist's father and son's separation, as well as the protagonist's journey into the dungeon with his grandfather, are introduced through the screen, making the subsequent plot more compact and complete. Therefore, the plot function of this film and television clip can be determined as "foreshadowing or foreshadowing the development of the subsequent plot."

For another example, the film and television clip from 49:30 to 53:32 of "XX Earth" is about the death of the protagonist's grandfather, which is the trigger for the protagonist's growth. This film and television clip has the function of "promoting the development of the storyline."

For example, the film and television clips from 1:17:55 to 1:21:53 of "XX Earth" are the plot where the protagonist and others formulate and prepare to implement a plan to save the earth, which makes the whole story begin to take a turn. In the face of the fear that the earth is about to be destroyed, Then there is new hope, which is a turning point in the development of the entire story, as well as a turning point in the emotions of the characters and the audience, bringing the story to a climax. Therefore, the plot function of this film and television clip can be determined as "setting up suspense to arouse the audience's interest" and "promoting the development of the storyline."

In a possible implementation manner, the second film and television clip can be analyzed according to the preset shooting technique of the film and television work, and at least one shooting technique of the second film and television clip can be determined. Among them, the preset filming techniques for film and television works can include a variety of techniques, such as: cutting techniques (including cutting movements, cuts, cross cuts, jump cuts, matching cuts, smash cuts, invisible cuts, L-shaped cuts and J-shaped cuts) , technical transition techniques, non-technical transition techniques, McGuffin techniques, montage, long shots, scene description, detail description, line drawing techniques, symbolic techniques, grotesque techniques, realistic techniques, space transformation, lens switching, etc. Those skilled in the art can set the preset shooting techniques for film and television works according to actual conditions, and this disclosure does not limit this.

For example, the film and television clips from 2:39 to 6:52 of "XX Earth", through the spatial transformation of multiple scenes, gradually introduce to the audience the beginning and end of the Wandering Earth Project, the separation of the protagonist's father and son, and the protagonist's entry into the dungeon with his grandfather. , not only does the news broadcast one by one not appear abrupt, but it can also connect the subsequent plots. Therefore, this film and television clip uses a spatial transformation shooting technique.

For another example, the film and television clips from 49:30 to 53:32 of "XX Earth" create a tense atmosphere of whether the grandfather can be successfully rescued, and promote the development of the story by switching between memories and reality. Therefore, this film and television clip adopts the shooting technique of camera switching.

For example, in the film and television clips from 1:17:55 to 1:21:53 of "XX Earth", close-ups, close-ups, and push shots are used many times to shoot the characters to reflect the characters' determination to implement the plan and their eagerness for the success of the plan. ; Many times panoramic shots and panning shots were used to shoot scenes to fully express the critical situation at that time and the severe situation when all large forces began to evacuate; the contrast between shooting people at a downward angle and shooting Jupiter at an elevation angle was used to express the human disaster at this time insignificance. Therefore, this film and television clip uses three shooting techniques: scene description, detail description, and spatial transformation.

It should be understood that those skilled in the art can determine the specific shooting techniques of film and television clips according to the actual conditions. This disclosure does not limit the specific shooting techniques and the number of filming techniques of film and television clips.
