屏幕录制中截图速率调整方法的比较研究

Research on comparison of screenshot rate adjustment methods in screen recording

为解决屏幕录制时的音视频同步问题,文章对屏幕录制时的截图速率调整方法进行了实验和比较。其中,文章对基于截屏等待时间的调整策略进行了建模和比较分析,并根据实验结果得出了较小调整率能够使截屏采样率更加稳定,较大调整率和动态调整率截屏方法能迅速调整顿率偏差的结论。此外,文章提出了对屏幕录制时视频和音频同步的建议。

To solve the problem of audio and video synchronization during screen recording,this article conducted experiments and comparisons on the methods of adjusting the screenshot rate during screen recording.Modeling and comparative analysis were conducted on adjustment strategies based on screen capture waiting time.Based on the experimental results,it was concluded that a smaller adjustment rate can make the screenshot sampling rate more stable,while a larger adjustment rate and dynamic adjustment rate screenshot method can quickly adjust the frame rate deviation.And suggestions were made for the synchronization of video and audio during screen recording.
