The video recording mode indicates that the terminal equipment is in a video recording process, namely, a video recording process is performed, and the camera is in an on state at the moment so as to record video.

Optionally, the preset instructions may include a rate selection instruction, a first rate adjustment instruction, and a second rate adjustment instruction, where the preset instructions are used to instruct to adjust the recording rate of the current recording, and the preset instructions further carry an adjustment rate to be adjusted, where the adjustment rate is used to instruct the adjusted recording rate. The preset instruction can be triggered manually or automatically, specifically, the rate selection instruction is triggered by a user, that is, if the user needs to adjust the recording rate in video recording, the rate selection instruction can be triggered in a preset mode, so that the terminal equipment detects the rate selection instruction. The preset mode can be set according to actual needs, for example, a rate selector is displayed on a display interface of the terminal equipment, so that a user can select the adjustment rate based on the rate selector and trigger a rate selection instruction while selecting the adjustment rate; or setting a rate selection button, a rate sliding block and the like on the terminal equipment so as to enable a user to select an adjustment rate and trigger a rate selection instruction when selecting the adjustment rate; the first rate adjustment instruction and the second rate adjustment instruction are automatically triggered by the terminal device, and the recording rate adjusted by the first rate adjustment instruction and the second rate adjustment instruction may be set according to practical situations, for example, the first rate adjustment instruction is used for adjusting the recording rate of the current recording to a normal recording rate (1 time speed), and the second rate adjustment instruction is used for adjusting the recording rate of the current recording to a previous recording rate.

In an embodiment, the preset command includes a rate selection command, and the step S10 includes:

Specifically, the rate selector is not hidden during video recording, i.e. the rate selector is displayed during video recording, so that the recording rate can be manually switched, and the aim of switching the recording rate at any time is fulfilled. The rate selector is used for a user to perform rate selection and rate adjustment, and specifically referring to fig. 4, fig. 4 is a schematic diagram of a screen of the video recording method of the present application, where the rate selector in fig. 4 may be located at any position on the screen, and may be set to a size according to actual needs, which is not limited herein.

Step A3, identifying whether the recorded picture is matched with a preset picture or not so as to detect whether a first speed adjusting instruction is triggered or not;

in this embodiment, whether the recorded picture matches with the preset picture is identified to detect whether the first rate adjustment command is triggered. Specifically, if the recorded picture is identified to be matched with the preset picture, a first speed adjusting instruction is detected. The first rate adjustment command is automatically triggered by the terminal device, and the recording rate adjusted by the first rate adjustment command may be set according to practical situations, for example, the first rate adjustment command is used for adjusting the recording rate of the current recording to a normal recording rate (1 time speed).

Specifically, if it is recognized that the recorded picture is changed from the preset picture to another picture, the triggering of the second rate adjustment command is detected. The second rate adjustment instruction is automatically triggered by the terminal device, and the recording rate adjusted by the second rate adjustment instruction may be set according to practical situations, for example, the second rate adjustment instruction is used for adjusting the recording rate of the current recording to the previous recording rate. The other pictures are pictures which are not preset pictures.

Based on the above, when the specified object or figure is identified, the normal recording rate (1 time speed) is automatically switched, and when the specified object or figure is not identified, the previous recording rate is switched, so that the automatic switching of the recording rate is realized. For example, a high rate may be selected before starting recording, at which recording begins. When the shot picture shows the appointed object or figure, the normal speed (1 time speed) recording is automatically switched, the current time point is recorded, when the picture does not show the appointed object or figure, the speed is automatically switched to the preset speed, and the recording is continued by the previous speed recording.

The method comprises the steps of marking a start recording time and an end recording time based on a preset rule, so that the start recording time and the end recording time of the mark can be checked later, and video clips with different playing rates can be determined. For example, after the whole video is recorded, according to each time point under the mark, the whole video is decomposed into a plurality of videos to be processed, and then the plurality of processed videos are integrated into one video, so that the predicted video is obtained, and the video with different playing rates is obtained. Recording is carried out on the starting recording time and the ending recording time based on a preset rule, so that the starting recording time and the ending recording time of the subsequent viewable records can be used for determining video clips with different playing rates. For example, after the whole video is recorded, the whole video is decomposed into a plurality of videos according to each recorded time point to be processed, and then the plurality of processed videos are integrated into one video, so that the predicted video is obtained, and the video with different playing rates is obtained.

In an embodiment, the step S40 includes: and taking the marked start recording time as the start time of the time slice corresponding to the first recording rate, and taking the marked end recording time as the end time of the time slice. In other embodiments, the adjustment may be performed according to a preset rule based on the start recording time and the end recording time, so that the adjusted start recording time is used as the start time of the time segment corresponding to the first recording rate, and the adjusted end recording time is used as the end time of the time segment corresponding to the first recording rate.

Optionally, based on the time slice, after the step S40, the recording method further includes:

and step A60, obtaining video recording videos with different playing rates based on the at least two time slices.

Specifically, the step of obtaining video recorded at different playing rates based on the at least two time slices includes:

step A61, when the terminal equipment ends the video recording mode, acquiring a complete video of the video recording mode;

Firstly, when the terminal equipment finishes the video recording mode, namely after the video recording is completed, the recorded data are generated into a complete video for obtaining the complete video of the video recording mode. The complete video is a complete video, i.e. a video with a playing rate still being a normal rate.

In one embodiment, the step a61 includes: and when the terminal equipment finishes the video recording mode, acquiring complete recorded data, and performing video generation processing on the complete recorded data to obtain a complete video of the video recording mode. The recording data is data obtained in the recording process and is used for generating video.

In some embodiments, the step a61 includes: and when the terminal equipment finishes the video recording mode, acquiring complete recorded data, and performing encoding and decoding processing on the complete recorded data to obtain a complete video of the video recording mode. The recording data is data obtained in the recording process and is used for generating video. The encoding and decoding process is a technical means of video generation process, which can be set according to actual needs, and will not be described in detail herein.

Step a62, decomposing the complete video into at least two video segments based on the at least two time segments;

The complete video is then decomposed into at least two video segments based on the at least two time segments. It will be appreciated that at least two time slices are used to distinguish between video slices having different recording rates, so that the complete video can be decomposed according to one-to-one correspondence.

For example, the first time segment is 0 to 30 seconds, the second time segment is 30 seconds to 1 minute, and the third time segment is 1 minute to 1 minute and 30 seconds, then the complete video is decomposed into a first video segment of 0 to 30 seconds, a second video segment of 30 seconds to 1 minute, and a third video segment of 1 minute to 1 minute and 30 seconds.

In one embodiment, after the step a62, the recording method further includes:

Specifically, whether at least two video clips trigger a third speed adjusting instruction is sequentially detected. That is, each small video may change the rate again, and then perform secondary processing according to the corresponding changed rate, that is, performing secondary encoding and decoding processing on the video clip.

Step A622, if a third rate adjustment command is triggered, determining a video clip to be adjusted and a play rate based on the third rate adjustment command;

In this embodiment, if the third rate adjustment command is triggered, the video clip to be adjusted and the playing rate are determined based on the third rate adjustment command. The third rate adjustment instruction is triggered by the user, that is, if the user needs to adjust the playing rate in editing the video, the third rate adjustment instruction may be triggered in a preset manner, so that the terminal device detects the third rate adjustment instruction. The preset mode can be set according to actual needs, for example, a rate selector is displayed on a display interface of the terminal equipment, so that a user can select the playing rate based on the rate selector and trigger a third rate adjusting instruction when selecting the playing rate; or, a rate selection button, a rate sliding block and the like are arranged on the terminal equipment so as to enable a user to select the playing rate, and a third rate adjusting instruction is triggered while the playing rate is selected.

It should be noted that, each video clip may trigger the third rate adjustment instruction, so that the third rate adjustment instruction carries information of the video clip to be adjusted corresponding to the adjustment, so as to determine the video clip to be adjusted based on the third rate adjustment instruction.

Step A623, performing play rate adjustment processing on the video clip to be adjusted based on the play rate;

In this embodiment, the play rate adjustment processing is performed on the video clips to be adjusted based on the play rate until at least two video clips are processed.

Step A63, obtaining at least two recording rates of the at least two video clips, and respectively performing play rate adjustment processing on the at least two video clips based on the at least two recording rates;

and then, respectively acquiring at least two recording rates of at least two video clips, and respectively carrying out play rate adjustment processing on the at least two video clips based on the at least two recording rates of the at least two video clips. Wherein the recording rate of each video clip is determined in the recording mode, i.e., during recording. The play rate adjustment process is a process of adjusting the play rate of the video clip according to the recording rate.

In some embodiments, the step a63 includes: acquiring at least two recording rates of the at least two video clips; determining the playing rates of the at least two video clips based on the at least two recording rates and a preset mapping relation; and respectively carrying out play rate adjustment processing on the at least two video clips based on the play rates of the at least two video clips. The preset mapping relationship is a mapping relationship between a recording rate and a playing rate, for example, a preset mapping table. The mapping relation can be set according to actual needs, and is usually the recording rate, the playing rate is the same, for example, the recording rate is 2 times the playing rate, and of course, other mapping relations are also possible. In other embodiments, if the recording rate is the same as the playing rate, the recording rate may be directly used as the playing rate without establishing a preset mapping relationship.

It should be noted that, the playing rate of the video clip after the playing rate processing is related to the recording rate of the video clip, so that the storage space occupied by the video clip after the playing rate processing may be smaller.

Based on the steps A621-A623, in one embodiment, the step A63 includes:

step a631, obtaining at least two recording rates of at least two video clips not subjected to the play rate adjustment processing, and based on the at least two recording rates, respectively performing the play rate adjustment processing on the at least two video clips not subjected to the play rate adjustment processing.

In this embodiment, at least two recording rates of at least two video clips not subjected to the play rate adjustment processing are obtained, and the play rate adjustment processing is performed on at least two video clips not subjected to the play rate adjustment processing based on the at least two recording rates. The at least two video clips which are not subjected to the play rate adjustment processing are video clips which are not triggered by the third rate adjustment instruction, namely video recording videos with different play rates are obtained later, and the third rate adjustment instruction and the recording rate adjusted in the recording process are determined together.

And step A64, integrating the at least two processed video clips to obtain video with different playing rates.

And finally, integrating the at least two processed video clips to obtain video videos with different playing rates, so that the storage volume of the video videos is reduced.

In one embodiment, the step a64 includes: determining the time sequence of the processed at least two video clips, and integrating the processed at least two video clips according to the time sequence to obtain video recording videos with different playing rates. The time sequence is the time sequence of at least two video clips before decomposition, and is used for ensuring that the integrated video and the complete video before decomposition have consistency in time sequence.

In another embodiment, the step D includes: acquiring an integration rule; and integrating the at least two processed video clips based on the integration rule to obtain video recording videos with different playing rates. The integration rule may be a preset rule, that is, a rule set in advance according to actual needs, or may be an integration rule set by a user in a video recording mode, which is used to make the video recorded after integration more flexible.

Optionally, after the step S40, the recording method further includes:

step A70, obtaining the recorded data corresponding to the time segment, and performing video generation processing on the recorded data to obtain a corresponding video segment;

firstly, recording data corresponding to a time slice is obtained, and video generation processing is carried out on the recording data to obtain a corresponding video slice. The recording data is data obtained in the recording process and is used for generating video.

In some embodiments, the step a70 includes: and acquiring the recorded data corresponding to the time segment, and performing encoding and decoding processing on the recorded data to obtain the corresponding video segment. The encoding and decoding process is a technical means of video generation process, which can be set according to actual needs, and will not be described in detail herein.

Step A80, obtaining a video before the recording time is started, and combining the video with the video segment to obtain the video before the recording time is ended;

and then, acquiring a video before the recording time is started, and combining the video with the video segment to obtain the video before the recording time is ended. The video before the recording time is the video combined before.

In one embodiment, the step a80 includes: and if no video exists before the recording starting time, taking the video clip as the video before the recording ending time, so that the video is the first-stage video. Specifically, if no video exists before the recording start time, that is, the recording start time is the recording start time of the recording mode, the video segments at this time do not need to be combined, and the video segments are directly used as the video before the recording end time, so that when other video segments are obtained later, the video segments are combined based on the video before the recording end time. It can be understood that the video before the end recording time is the video before the start recording time of the next stage, so as to obtain the video before the start recording time later, and combine the video with the video clip.

In addition, it should be noted that, if the ending recording time at this time is the ending time of the recording mode, the recorded video before the ending recording time at this time is the final recorded video, that is, the recorded video having different playing rates and being complete.

And step A90, taking the ending recording time as the starting recording time of the next time segment, returning to the step of determining the triggering time of the preset instruction if the preset instruction is triggered after the starting recording time, taking the triggering time as the ending recording time corresponding to the first recording rate until the recording mode is ended, and obtaining the recorded videos with different playing rates.

And finally, taking the ending recording time as the starting recording time of the next time slice, returning to the step S30, if the preset command is triggered after the starting recording time, determining the triggering time of the preset command, taking the triggering time as the ending recording time corresponding to the first recording rate, and finishing recording until the recording mode is ended, so as to obtain the recorded videos with different playing rates.

When the recording speed is switched, the video is recorded at a selected speed, and when the recording speed is switched, the first video is recorded and is finished, and video generation processing is directly carried out to obtain the corresponding video segment. At this time, the display page of the terminal device is not provided with a prompt for ending the recording and starting the recording, but the prompt rate is replaced, and the second recording is started at the updated rate. And when the rate is switched for the second time, video generation processing is carried out on the second section of video, and the processed second section of video is combined with the first section of video to obtain a continuous video. And the like until the video recording is finished, namely the video recording mode is finished.
