How does increasing the frame rate affect bitrate?

Increasing the frame rate of a video affects the amount of data that needs to be processed and transmitted, directly impacting the bitrate. Bitrate refers to the amount of data transmitted for each second of video. When the frame rate increases, more frames are captured and displayed per second. Each frame contains a certain amount of visual information, and with more frames being added, the total amount of data necessary to represent this video in a given time period increases as well.

For instance, if you are capturing video at 30 frames per second (fps) and decide to increase that to 60 fps, you are effectively doubling the number of frames. Each frame carries its own data, so by introducing more frames, there is a greater volume of data to be encoded. This necessitates a higher bitrate in order to maintain the same level of video quality and ensure smooth playback without artifacts such as blurring or loss of detail.

Simply put, if the bitrate does not increase sufficiently to accommodate the additional frames, the quality of the video may suffer, potentially leading to issues like pixelation or frame skipping. Therefore, increasing the frame rate is generally associated with an increase in bitrate to preserve overall video quality.
