Referring to fig. 1, an embodiment of the present invention provides a video recording method applied to electronic devices, which include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of Mobile Stations (MSs), Terminal devices (Terminal devices), and so on.
The method comprises the following steps:
Wherein, the time unit can be a time value such as second or millisecond; the method comprises the steps that in the process of recording videos, electronic equipment obtains video recording parameters of a first time unit. The video recording parameters comprise a first frame rate of a first time unit and a first state parameter; specifically, the video recording Frame rate is a Frame rate adopted by the electronic device during the video recording process, and the Frame rate (Frame rate) refers to a frequency (or rate) at which bitmap images in units of frames continuously appear on a display screen of the electronic device, and the higher the Frame rate is, the more the number of recorded image frames per time unit is.
The first state parameter is a state parameter detected by the target sensor in a first time unit, and the state parameter is used for representing the motion state of the electronic equipment; the first state parameter includes a first acceleration and a first velocity. Alternatively, the target sensor may be a sensor that can detect acceleration and velocity, such as a gyroscope.
Further, the first acceleration may also be calculated from a rate, e.g., a third rate and a first duration of a time unit prior to the first time unit, and the first rate: the difference between the first speed and the third speed is divided by the first time length, and the obtained data is the first acceleration.
Optionally, if the first time unit is a time unit between the current times, the second time unit may be a time unit corresponding to the current time; if the first time unit is the time unit to which the current time belongs, the second time unit may be the time unit corresponding to the next time.
After the first acceleration and the first speed are obtained, calculating a second estimated speed of a second time unit according to the first acceleration and the first speed, and then adjusting the first video recording frequency according to the relation between the second estimated speed and the first speed; for example, if the second estimated rate is greater than the first rate, the first video recording frequency is increased, and the video recording frame rate of the second time unit is increased; if the second estimated speed is smaller than the first speed, the first video recording frequency is reduced, and the video recording frame rate of a second time unit is reduced.
And 103, recording the target video segment according to the second frame rate in the second time unit.
And recording the video segments according to the second frame rate in a second time unit, and adjusting the video recording frame rate according to the rate change condition of the electronic equipment to enable the video recording frame rate to be matched with the moving rate.
In the embodiment of the invention, video recording parameters of electronic equipment in a first time unit are obtained; determining a second frame rate of a second time unit according to the first frame rate and the first state parameter; recording a target video segment according to the second frame rate in the second time unit; therefore, the electronic equipment can adjust the video recording frame rate according to the rate change condition, so that the video recording frame rate is matched with the motion state of the electronic equipment, and the playing picture rate of the recorded video is more uniform. The embodiment of the invention solves the problem that the picture rate is uneven when the video recorded by the electronic equipment is played in the prior art.
Optionally, in this embodiment of the present invention, the recording, in the second time unit, the target video segment according to the second frame rate includes a case one or a case two, specifically,
the first condition is as follows: and if the first rate is zero, the second frame rate is equal to the first frame rate.
And if the speed value in the first time unit is zero, the second frame rate is equal to the first frame rate, and the recording frame rate does not need to be changed.
In case two, if the first speed is not zero, determining a second estimated speed of the second time unit according to the first acceleration and the first speed; determining the second frame rate according to the second pre-estimated rate, the first rate and a first formula, wherein the first formula is as follows:
wherein F2 is the second frame rate, F1 is the first frame rate, V2 is the second estimated rate, and V1 is the first rate.
If the first speed is not zero, the electronic equipment has an acceleration value in a first time unit, which indicates that the motion state of the electronic equipment changes, and further adjusts the second video recording speed, the adjustment process is executed according to a first formula, and the video recording frame rate is proportionally adjusted according to the proportion that the speed difference value between the second estimated speed and the first speed occupies the first speed, so that the process of adjusting the video recording frame rate has the same rule.
As a first example, see fig. 2 to 5, fig. 2 to 5 are schematic diagrams of simulation results, in which the horizontal axis represents time, and t1, t2, … …, t5 represent time; wherein, fig. 2 is a time variation curve of the acceleration of the electronic device, fig. 3 is a time variation curve of the velocity (v1) of the electronic device, fig. 4 is a time variation curve of the playing screen velocity (v2) of the video without video frame rate adjustment, and fig. 5 is a time variation curve of the playing screen velocity (v3) of the video with video frame rate adjustment; as can be seen from the comparison between fig. 4 and fig. 5, the picture playing rate is more stable and uniform after the video recording frame rate is adjusted.
Referring to fig. 6, another embodiment of the present invention provides a video recording method applied to an electronic device, where the method includes:
601, acquiring video recording parameters of electronic equipment in a first time unit; the video recording parameters comprise a first frame rate and first state parameters detected by a target sensor of the electronic equipment, and the first state parameters at least comprise a first acceleration and a first speed.
Wherein, the time unit can be a time value such as second or millisecond; the method comprises the steps that in the process of recording videos, electronic equipment obtains video recording parameters of a first time unit. The video recording parameters comprise a first frame rate of a first time unit and a first state parameter; specifically, the video recording Frame rate is a Frame rate adopted by the electronic device during the video recording process, and the Frame rate (Frame rate) refers to a frequency (or rate) at which bitmap images in units of frames continuously appear on a display screen of the electronic device, and the higher the Frame rate is, the more the number of recorded image frames per time unit is.
The first state parameter is a state parameter detected by the target sensor in a first time unit, and the state parameter is used for representing the motion state of the electronic equipment; the first state parameter includes a first acceleration and a first velocity. Alternatively, the target sensor may be a sensor that can detect acceleration and velocity, such as a gyroscope.
Further, the first acceleration may also be calculated from a rate, e.g., a third rate and a first duration of a time unit prior to the first time unit, and the first rate: the difference between the first speed and the third speed is divided by the first time length, and the obtained data is the first acceleration.
After the first acceleration and the first speed are obtained, calculating a second estimated speed of a second time unit according to the first acceleration and the first speed, and then adjusting the first video recording frequency according to the relation between the second estimated speed and the first speed; for example, if the second estimated rate is greater than the first rate, the first video recording frequency is increased, and the video recording frame rate of the second time unit is increased; if the second estimated speed is smaller than the first speed, the first video recording frequency is reduced, and the video recording frame rate of a second time unit is reduced.
And recording the video segments according to the second frame rate in a second time unit, and adjusting the video recording frame rate according to the rate change condition of the electronic equipment to enable the video recording frame rate to be matched with the moving rate.
The video recording frame rates (i.e., the second frame rates) adopted by each time unit may be different or the same, so that the recorded video segments are distinguished according to different video recording frame rates, for example, 2 time units that are continuous in time, and if the video recording frame rates are the same, the video segments recorded in the 2 time units are stored as one video segment, and the corresponding relationship between each video recording frame rate and the corresponding video segment is recorded.
It can be understood that, in the correspondence, although the video clips are adjusted, the video clips in the correspondence are still sorted according to the chronological order.
Further, in this embodiment of the present invention, after recording the correspondence between the second frame rate and the target video segment, the method may further include:
acquiring the original time length of each video clip;
and adjusting the time length of at least one video clip according to the corresponding relation and the original time length.
Acquiring the original time length of each video clip in the corresponding relation, and then adjusting the original time length according to the corresponding relation and the original time length; because the video recording frame rates are different, the part with the high frame rate can be distributed into a longer time segment, and the part with the low frame rate can be compressed into a shorter time segment.
Further, in this embodiment of the present invention, optionally, the adjusting the duration of at least one of the video segments according to the corresponding relationship and the original duration includes a first step and a second step:
the first step is to obtain a third video recording frame rate of the first video segment and a fourth video recording frame rate of the second video segment.
The first video segment is any video segment in the corresponding relation, and the video recording frame rate of the first video segment is obtained aiming at any video segment in the corresponding relation, namely the third video recording frame rate; and acquiring a fourth video recording frame rate of the second video segment. The second video segment may be a next video segment adjacent to the first video segment.
And secondly, adjusting the first original time length of the second video clip according to a second formula to obtain the adjusted target time length, wherein the second formula is as follows:
wherein T2 is the target duration, T1 is the first original duration, F4 is the fourth video recording frame rate, and F3 is the third video recording frame rate.
And proportionally adjusting the target duration based on the proportional relation between the third video recording frame rate and the fourth video recording frame rate, so that the variation difference of the Frame Per Second (FPS) is small, and the duration of each video segment after adjustment is in direct proportion to the video recording frame rate.
As a second example, see fig. 7 and 8, where the horizontal axis represents time, t1, t2, … …, t5 represents time of day; FIG. 7 is a schematic diagram showing the change of the FPS over time before the first and second adjustments, where f1 represents the FPS; after the above first and second adjustments, the FPS is shown in FIG. 8 with a schematic diagram of the time variation, f2 representing the FPS; after the adjustment, the FPS change amplitude is reduced.
Optionally, in the above embodiments of the present invention, the method may further include:
storing the video file recorded by the electronic equipment as an editable video source file;
receiving N target image frames selected by a user from the editable video source file, wherein N is a positive integer;
receiving the editing operation of the user for the N target image frames; the editing operation comprises prolonging or shortening the playing time corresponding to the N target image frames by a preset time variable;
and averagely distributing the preset time variable to the target image frame.
The editable video source file can be an evsf file, and after the electronic equipment records the video file, the video file is firstly stored as an editable video source file; then receiving a target image frame selected by a user; the user can edit the selected target video frames, wherein the editing operation comprises lengthening or shortening all the selected target image frames; for example, an extension button is set, and a user can extend a preset time variable every time the user touches the button.
Wherein, N is a positive integer, if N is 1, the total time variable of the editing operation is directly configured to the target image frame; and if N is larger than 1, averagely distributing the total time variable of all editing operations to all target image frames.
As a third example, as shown in fig. 9, fig. 9 is a schematic interface diagram illustrating an editing operation. Wherein, after opening an editing window for editing the evsf file; the user may select a target image frame from the frame view area by the user through the bottom frame view area (i.e., the area shown with 1, 2, 3, … …, 6, each number representing an image frame).
An editing operation area is arranged above the frame view area, wherein, for example, if a user triggers a slow 0.5 second key, 0.5 seconds are evenly divided into target image frames, and the overall playing speed is reduced; or the user triggers the 'fast 0.5 second' key, the 0.5 second is evenly divided into the target image frames, and the overall playing speed is accelerated.
In the embodiment of the invention, video recording parameters of electronic equipment in a first time unit are obtained; determining a second frame rate of a second time unit according to the first frame rate and the first state parameter; wherein the second time unit is a next time unit of the first time unit; recording a target video segment according to the second frame rate in the second time unit; and adjusting the video recording frame rate according to the rate change condition, so that the video recording frame rate is matched with the motion state of the electronic equipment, and the picture playing rate of the recorded video is uniform when the video is played.
