What does iFrame recording mode mean?

iFrame recording mode refers to using iFrame mode for encoding during video recording or live broadcast. In iFrame recording mode, the video stream will be based on iFrame and periodically insert key frames to ensure video quality and stability. The advantage of this is that even if packet loss or error occurs during transmission, it will only affect the frames between the current and next iFrame, not the entire video stream. This encoding provides better error tolerance and reduces video quality degradation caused by transmission errors.

"iFrame recording mode" refers to using iFrame mode for encoding during video recording or live broadcast. In video coding, iFrame refers to a key frame (Intra Frame), which is a complete and independent video frame that does not depend on other frames for decoding. The P frame (Predicted Frame) and B frame (Bi-directional Predicted Frame) are compressed and encoded with reference to the previous and next frames.

In iFrame recording mode, the video stream will be based on iFrame and periodically insert key frames to ensure video quality and stability. The advantage of this is that even if packet loss or error occurs during transmission, it will only affect the frames between the current and next iFrame, not the entire video stream. This encoding provides better error tolerance and reduces video quality degradation caused by transmission errors.

iFrame recording mode is commonly used in scenarios such as video conferencing, real-time live broadcast, and video surveillance to provide a more reliable and stable video transmission and playback experience.
