Description
本発明は、動画編集装置、動画編集方法及びプログラムに関し、特に、第１の解像度の編集対象動画データを、第１の解像度より低い解像度の変換動画データに変換する変換装置により変換された変換動画データを用いて、編集対象動画データを編集する動画編集装置、動画編集方法及びプログラムに関する。
The present invention relates to a moving image editing apparatus, a moving image editing method, and a program, and in particular, a converted moving image converted by a conversion device that converts editing target moving image data having a first resolution into converted moving image data having a resolution lower than the first resolution. The present invention relates to a moving image editing apparatus, a moving image editing method, and a program for editing editing target moving image data.
近年、デジタルカメラやデジタルビデオカメラのような映像を撮像する電子機器において、撮像する際の画素数は、現在普及しているＨＤサイズ（１９２０×１０８０ピクセル）に加え、ＨＤサイズより解像度が高い４Ｋ２Ｋサイズ（３８４０×２１６０ピクセル）が普及しつつある。
In recent years, in electronic devices that capture images such as digital cameras and digital video cameras, the number of pixels at the time of capturing is 4K2K, which is higher in resolution than the HD size in addition to the currently popular HD size (1920 × 1080 pixels). Size (3840 × 2160 pixels) is becoming popular.
４Ｋ２Ｋサイズの画素数で撮像された動画ファイルは、ＨＤサイズの画素数で撮像された動画ファイルに比べ、撮像したシーンをより精細に表現できる一方、ファイルサイズが大きくなり、その編集作業に多大な時間を要すると言う問題がある。
A moving image file captured with 4K2K pixels can express the captured scene more precisely than a moving image file captured with HD pixels, but the file size is large, and the editing process is very large. There is a problem that it takes time.
このため、例えば、動画編集の処理負荷を軽減する技術として、作成されたサムネイルを使用して動画の編集作業が行われ、その後に、編集作業の内容が取り込んだオリジナルの動画に反映される動画編集装置が提案されている（特許文献１）。
For this reason, for example, as a technology to reduce the processing load of video editing, video editing work is performed using the created thumbnails, and then the video that is reflected in the original video captured by the editing work content An editing apparatus has been proposed (Patent Document 1).
特許文献１の動画編集装置によれば、編集作業は、高解像度・高画質のデータ量の多い動画フレームではなく、そのフレームを基に解像度変換（画素数変換）によってサイズを縮小したデータ量の少ないサムネイルを使用して行われる。そのため、編集のための処理負荷を軽減させることができる。
According to the moving image editing apparatus of Patent Document 1, the editing operation is not a moving image frame with a large amount of high-resolution and high-quality data, but a data amount whose size is reduced by resolution conversion (pixel number conversion) based on the frame. This is done using fewer thumbnails. Therefore, the processing load for editing can be reduced.
ところで、４Ｋ２Ｋサイズで撮像された動画ファイルは、ＨＤサイズで撮像された動画ファイルに比べ、高精細であることに加え、撮像したシーンの色の再現性が極めて高い。しかしながら、仮に、４Ｋ２Ｋサイズで撮像された動画ファイルを、特許文献１の技術により、ファイルサイズを縮小した場合、データ量が少なくなり調整範囲が狭くなるため、この撮像されたシーンの色を再現するための自由度が損なわれる。
By the way, the moving image file captured in the 4K2K size has a higher definition and the reproducibility of the color of the captured scene than the moving image file captured in the HD size. However, if the file size of a moving image file captured in 4K2K size is reduced by the technique of Patent Document 1, the data amount is reduced and the adjustment range is narrowed, so that the color of the captured scene is reproduced. The degree of freedom for this is lost.
本発明は、４Ｋ２Ｋサイズで撮像された動画ファイルの編集時間を削減できるとともに、撮像されたシーンの色を再現するための自由度を維持できる動画編集装置、動画編集方法及びプログラムを提供することを目的とする。
The present invention provides a moving image editing apparatus, a moving image editing method, and a program capable of reducing the editing time of a moving image file captured in 4K2K size and maintaining the degree of freedom for reproducing the color of the captured scene. Objective.
（１） 第１の解像度の編集対象動画データを、前記第１の解像度より低い解像度の変換動画データに変換する変換装置により変換された前記変換動画データを用いて、前記編集対象動画データを編集する動画編集装置であって、前記変換動画データにおける全再生時間のうち、使用する時間帯を示す使用時間情報を、前記編集対象動画データに対応付ける時間情報対応付手段と、前記編集対象動画データにおいて、前記使用時間情報が示す時間帯のみに行ったカラーグレーディングによる色に関する色情報を、前記編集対象動画データに対応付ける色情報対応付手段と、を備える動画編集装置。
(1) Editing the editing target moving image data using the converted moving image data converted by the conversion device that converts the editing target moving image data having the first resolution into the converted moving image data having a resolution lower than the first resolution. A time information correlating means for associating the editing target video data with usage time information indicating a time zone to be used among all playback times in the converted video data, A moving image editing apparatus comprising: color information association means for associating color information related to colors by color grading performed only in a time zone indicated by the usage time information with the editing target moving image data.
（１）の構成によれば、動画編集装置は、第１の解像度（例えば、４Ｋ２Ｋサイズ）の編集対象動画データを、第１の解像度より低い解像度（例えば、ＨＤサイズ）の変換動画データに変換する変換装置により変換された変換動画データを用いて、編集対象動画データを編集する。動画編集装置は、時間情報対応付手段と、色情報対応付手段と、を備える。時間情報対応付手段は、変換動画データにおける全再生時間のうち、使用する時間帯（尺）を示す使用時間情報を、編集対象動画データに対応付ける。色情報対応付手段は、編集対象動画データにおいて、使用時間情報が示す時間帯のみに行ったカラーグレーディングによる色に関する色情報を、編集対象動画データに対応付ける。
According to the configuration of (1), the moving image editing apparatus converts the editing target moving image data having the first resolution (for example, 4K2K size) into converted moving image data having a resolution (for example, HD size) lower than the first resolution. Editing moving image data is edited using the converted moving image data converted by the converting device. The moving image editing apparatus includes time information association means and color information association means. The time information association means associates the usage time information indicating the time zone (scale) to be used, among the total reproduction times in the converted video data, with the editing target video data. The color information associating means associates color information relating to colors by color grading performed only in the time zone indicated by the usage time information in the editing target moving image data with the editing target moving image data.
これにより、例えば、テレビ等で放送するための編集後の動画データの制作過程において、解像度が低い変換動画データ（例えば、ＨＤサイズ）において、全再生時間のうち、編集後の動画ファイルで使用する時間帯（尺）を選定し、編集対象動画データ（例えば、４Ｋ２Ｋサイズ）において、選定した時間帯のみにカラーグレーディングを行うことが可能となる。よって、編集対象動画データに対してカラーグレーディングを行うことを可能とすることで、撮像されたシーンの色を再現するための自由度を維持できるとともに、選定した時間帯のみにカラーグレーディングを行うことを可能とすることで、編集対象動画データ全体に対してカラーグレーディングを行った場合に比べ、カラーグレーディングに要する時間を削減できる。
Thus, for example, in the production process of edited moving image data for broadcasting on a television or the like, the converted moving image data with a low resolution (for example, HD size) is used in the edited moving image file out of the total reproduction time. A time zone (scale) is selected, and color grading can be performed only in the selected time zone in the editing target moving image data (for example, 4K2K size). Therefore, by making it possible to perform color grading on the video data to be edited, the degree of freedom for reproducing the color of the captured scene can be maintained, and color grading can be performed only in the selected time zone. As a result, the time required for color grading can be reduced as compared with the case where color grading is performed on the entire moving image data to be edited.
したがって、４Ｋ２Ｋサイズで撮像された動画ファイルの編集時間を削減できるとともに、撮像されたシーンの色を再現するための自由度を維持できる。

ステップＳ８の４Ｋ２Ｋタイムライン生成処理において、オフライン編集装置３０は、ユーザの操作に基づき、ステップＳ６又は後述するステップＳ１３で変換装置２０から出力された編集後動画データを複数受付して、これら複数の編集後動画データが連なる４Ｋ２Ｋタイムラインを生成する。また、オフライン編集装置３０は、カラーグレーディングを行わない場合には、動画編集装置１０から出力された使用時間情報に基づき編集済み尺動画データを生成し、複数の編集済み尺動画データが連なる４Ｋ２Ｋタイムラインを生成する。
In the 4K2K timeline generation process in step S8, the offline editing device 30 receives a plurality of edited video data output from the conversion device 20 in step S6 or step S13 described later based on the user's operation, and A 4K2K timeline in which the edited moving image data is continuous is generated. Further, when the color grading is not performed, the offline editing device 30 generates edited scale moving image data based on the usage time information output from the moving image editing device 10, and a 4K2K time in which a plurality of edited length moving image data is connected. Generate a line.
以下に説明するステップＳ１１からステップＳ１３の処理は、変換装置２０において、セカンダリカラーグレーディングを行う場合の処理である。本実施形態における「セカンダリカラーグレーディング」は、編集済み尺動画データの特定の部分にのみカラーグレーディングを行うことを言う。
The processing from step S11 to step S13 described below is processing when secondary color grading is performed in the conversion device 20. “Secondary color grading” in the present embodiment refers to performing color grading only on a specific portion of edited scale moving image data.
セカンダリカラーグレーディングを行う場合、変換装置２０は、４Ｋファイル（例えば、ＤＰＸファイル）を生成し（ステップＳ１１）、ユーザの操作に基づき、この４Ｋファイルに対してセカンダリカラーグレーディングを行い（ステップＳ１２）、ムービー変換（例えば、ＤＰＸファイルからムービーファイルへの変換）を行う。
When performing secondary color grading, the conversion apparatus 20 generates a 4K file (for example, a DPX file) (step S11), performs secondary color grading on the 4K file based on a user operation (step S12), Movie conversion (for example, conversion from a DPX file to a movie file) is performed.
本実施形態によれば、例えば、テレビ等で放送するための編集後の動画データの制作過程において、解像度が低い変換動画データ（例えば、ＨＤサイズ）において、全再生時間のうち、編集後の動画ファイルで使用する時間帯を選定し、編集対象動画データ（例えば、４Ｋ２Ｋサイズ）において、選定した時間帯のみにカラーグレーディングを行うことが可能となる。よって、編集対象動画データに対してカラーグレーディングを行うことを可能とすることで、撮像されたシーンの色を再現するための自由度を維持できるとともに、選定した時間帯のみにカラーグレーディングを行うことを可能とすることで、編集対象動画データ全体に対してカラーグレーディングを行った場合に比べ、カラーグレーディングに要する時間を削減できる。
According to the present embodiment, for example, in the production process of edited video data for broadcasting on a television or the like, in the converted video data with a low resolution (for example, HD size), the edited video in the total playback time. A time zone used in the file is selected, and color grading can be performed only in the selected time zone in the editing target moving image data (for example, 4K2K size). Therefore, by making it possible to perform color grading on the video data to be edited, the degree of freedom for reproducing the color of the captured scene can be maintained, and color grading can be performed only in the selected time zone. As a result, the time required for color grading can be reduced as compared with the case where color grading is performed on the entire moving image data to be edited.
したがって、４Ｋ２Ｋサイズで撮像された動画ファイルの編集時間を削減できるとともに、撮像されたシーンの色を再現するための自由度を維持できる。
Therefore, it is possible to reduce the editing time of the moving image file captured in the 4K2K size and maintain the degree of freedom for reproducing the color of the captured scene.
また、本実施形態によれば、動画データベース１００において、同じ識別情報により、編集対象動画データ及び当該編集対象動画データから変換された変換動画データを管理できる。よって、例えば、ある変換動画データの使用時間情報を、当該変換動画データの変換元である編集対象動画データとは異なる編集対象動画データに対応づけてしまうことを防止できるので、動画データベースを用いた編集作業の正確性を向上できる。
Further, according to the present embodiment, in the moving image database 100, the editing target moving image data and the converted moving image data converted from the editing target moving image data can be managed with the same identification information. Therefore, for example, it is possible to prevent the usage time information of certain converted moving image data from being associated with editing target moving image data different from the editing target moving image data that is the conversion source of the converted moving image data. The accuracy of editing work can be improved.
また、本実施形態によれば、識別情報に、ランダムに決定された文字列を含めることで、１つの編集対象動画データ及び当該編集対象動画データから変換された変換動画データを特定できる。よって、動画データベースを用いた編集作業の正確性をより向上できる。
In addition, according to the present embodiment, by including a randomly determined character string in the identification information, one editing target moving image data and converted moving image data converted from the editing target moving image data can be specified. Therefore, the accuracy of editing work using the moving image database can be further improved.
