Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method, apparatus, computer device and readable storage medium for previewing video material provided by the present invention are described with reference to the accompanying drawings.
Example one
An embodiment of the present invention provides a method for previewing a video material, where fig. 1 is an optional flowchart of the method, and as shown in fig. 1, the method specifically includes the following steps:
step S101: and acquiring a video to be edited, and determining the length of the track according to the playing time of the video to be edited.
Specifically, the acquiring the video to be edited includes:
and acquiring the video to be edited from a local photo album of the terminal, or shooting the video through a camera of the terminal to obtain the video to be edited.
Further, the determining the track length according to the playing duration of the video to be edited includes:
converting the playing time length into standard playing time length with the unit of second, finding out the corresponding time length and length proportion according to the standard playing time length, and determining the track length according to the time length and length proportion.
For example, when the playing time of the video to be edited is 1 minute, the standard playing time of the video to be edited is 60 seconds; the preset length-to-length ratio of 10 seconds corresponds to 1 centimeter, so that the track length of the video to be edited is 6 centimeters. It should be noted that different time length to length ratios are preset according to different standard playing time lengths, for example, for a video with a standard playing time length of less than 20 seconds, the time length to length ratio is 1 second to 1 cm, and for a video with a standard playing time length of more than 20 seconds and less than 60 seconds, the time length to length ratio is 10 seconds to 1 cm.
Step S102: and creating a video track according to the track length, and adding a picture frame for previewing the video to be edited in the video track.
Specifically, the adding of the picture frame for previewing the video to be edited in the video track includes:
determining a time interval according to the playing duration of the video to be edited;
and extracting picture frames from the video to be edited according to the time interval, and sequentially adding the extracted picture frames into the video track.
For example, when the playing time of the video to be edited is 1 minute, the time interval is determined to be 10 seconds, the picture frames of 10 th, 20 th, 30 th, 40 th, 50 th and 60 th seconds are extracted from the video to be edited, and the extracted picture frames are sequentially added to a video track with the track length of 6 centimeters.
The video content of the video to be edited can be roughly previewed through the picture frames in the video track, so that a later user can locate a position where video editing is needed based on the video content.
Step S103: when the fact that the materials are added in the video to be edited is detected, a material track is created according to the track length, and marks used for representing the materials are added at the corresponding position of the material track.
Specifically, step S103 includes:
judging whether a material track corresponding to the type of the material exists or not;
if yes, adding an identifier for representing the material at a corresponding position on an existing material track;
and if not, creating a material track corresponding to the type of the material, and adding an identifier for representing the material at a corresponding position on the created material track.
In an embodiment of the invention, the material includes the following types: theme, filter, background music, text, sticker, special effect; creating a corresponding material track for each type of material according to the type of the material added in the video to be edited; for example, if background music, characters and stickers are added to the video to be edited, a music material track, a character material track and a sticker material track are respectively created; in addition, in the embodiment of the invention, in order to avoid the repeated creation of the material track, only one material track is created for a plurality of materials of the same type; for example, two pieces of background music are added at the beginning and the end of the video to be edited, respectively, a first identifier is added at the front end of the music material track, and a second identifier is added at the tail end of the music material track. In practical application, in order to distinguish various types of material tracks, a corresponding track type identifier may be set in front of each material track; the identifier added to the material track to represent the material may be a material name and a material attribute, such as: music name, special effect name.
Further, adding an identifier for representing the material at a corresponding position of the material track specifically includes:
determining starting and ending time points of the material appearing in the video to be edited;
and determining a starting and stopping position corresponding to the starting and stopping time point on the material track, and adding an identifier for representing the material at the starting and stopping position.
For example, characters are added in the video to be edited with the playing time of 1 minute, and the characters are added in the 20 th to 40 th seconds; and calculating the starting and stopping positions (2 cm to 4 cm) according to the track length of 6 cm, the playing time of 1 min and the starting and stopping time points (20 s to 40 s), namely adding the material marks at the positions of 2 cm to 4 cm of the corresponding material track.
Step S104: and displaying the video track and the material track in a user display interface.
Specifically, step S104 includes:
and longitudinally arranging the video track and the material track in the user display interface, wherein the starting position of the video track is aligned with the starting position of the material track.
As shown in fig. 2, an interface is displayed for a user containing a video track and a material track; the user display interface includes two areas: a video display area and a track display area; the video display area is used for playing the video to be edited, and the track display area is used for displaying the video tracks and the material tracks.
Further, the longitudinally arranging the video track and the material track in the user display interface specifically includes:
acquiring the interface width of the user display interface, and judging whether the interface width is smaller than the track length;
if so, intercepting the track content with the set length away from the initial position of the video track from the video track, intercepting the track content with the set length away from the initial position of the material track from the material track, and longitudinally arranging the intercepted track content in the user display interface; wherein the set length is less than the interface width;
and if not, longitudinally arranging all track contents of the video track and the material track in the user display interface.
Because the playing time of the video to be edited can be long or short, and because the length of the track corresponding to the long video is long, if the video tracks and all the material tracks are all displayed in the user display interface, the track content is crowded to a small space, which is not beneficial to the watching and searching of the user. In order to solve the problem of displaying the track content of the long video, in the embodiment of the invention, only part of the track content is displayed in the user display interface.
When the video to be edited is not played, acquiring track contents with set lengths away from the initial position from the video track and each material track respectively; for example, as shown in fig. 3, the schematic diagram of a user display interface when a video to be edited is not played is shown, and a reference timeline is set in the middle of a track display area of the user display interface and is used for determining a currently played time point; since the interface width of the user display interface is 6 cm, the track content of the first 3 cm is acquired from the video track and each material track respectively to be displayed in the user display interface.
Further, when the interface width is less than the track length, after the displaying the video track and the material track in a user display interface, the method further comprises:
and in the process of playing the video to be edited, synchronously translating the video track and the material track according to the playing speed.
Specifically, the video track and the material track are translated synchronously according to the playing speed; the method specifically comprises the following steps:
and determining the track translation distance required to move every second according to the playing speed, and simultaneously moving the video track and each material track forward by the track translation distance every second.
For example, when the playback speed is single-time playback, it is determined that the movement needs to be 0.1 cm per second according to the track length (6 cm) and the playback time (1 min); in the process of playing the video, the video track and each material track are moved forward 0.1 cm per second at the same time.
Further, when the interface width is less than the track length, after the displaying the video track and the material track in a user display interface, the method further comprises:
step A1: when a video adjusting instruction is acquired on the video track, determining a track translation distance and a track translation direction corresponding to the video adjusting instruction;
step A2: and simultaneously translating the video track and the material track by the track translation distance according to the track translation direction.
Wherein the video adjustment instruction comprises: a user sliding distance and a user sliding direction;
step a1, specifically including:
calculating a track translation distance according to the user sliding distance in the video adjusting instruction; and determining the track translation direction according to the user sliding direction in the video adjusting instruction.
In the embodiment of the invention, a user can adjust the playing progress of the video to be edited by sliding the video track; when a user adjusts the playing progress by sliding the video track, the video track and each material track need to be adjusted correspondingly according to the sliding operation of the user.
In the embodiment of the invention, all the materials added in the video to be edited by a user are obtained, and a corresponding material track is created for each type of material; adding material identification at the corresponding position of the material track of the corresponding type aiming at one material; displaying each material track with the material identification in a user display interface so that a user can visually observe the type information, the position information and the attribute information of the material added in the video to be edited; in addition, when the video to be edited is played, the track content in the user display interface can be synchronously adjusted along with the playing progress of each material track, so that the user can see and obtain the video.
