AI Technical Summary
Technical Problem
Existing video encoders cannot dynamically adjust encoding parameters according to the intensity and complexity of motion in different video frames during the encoding process, resulting in poor encoding quality.
Method used
By determining the actual and target total encoding duration of the video frames in the current sliding window, as well as the actual and target total encoding duration of the encoded video frames, the encoding level and encoding parameters are dynamically adjusted to adapt to the characteristics of different video frames.
Benefits of technology
It improves the performance and efficiency of video encoding, ensures more reasonable encoding time for complex and simple video frames, and enhances the video encoding effect.

Abstract
本公开提供了一种视频编码方法、装置和设备，本公开涉及人工智能领域，具体涉及云计算、视频编码技术，可应用在智能云场景下。具体实现方案为：在编码过程，基于当前滑动窗口中所有视频帧的第一实际总编码时长、第一目标总编码时长、在所述当前滑动窗口之前的已编码视频帧的第二实际总编码时长和第二目标总编码时长，来确定对所述当前滑动窗口的下一个滑动窗口中视频帧进行编码时所使用的第二编码档位，并基于第二编码档位所对应的编码参数对下一个滑动窗口中的视频帧进行编码，从而实现在编码过程中对编码参数进行调整，提高了编码性能。
