The benefits of b frames

Available in main and high profiles b frames are a means of using a frame or slice using information from the previous and next frames/slices. Ultimately this means that less bits are required to recreate the full frame image which can mean higher quality at lower bit rates.

Usually in an encoder you can use 1, 2 or more b frames used which tell the encoder to insert a certain number of b frames between I or P frames.

In some cases encoders may also allow you to select pyramid b frames (or p frames) what this means is that the encoder will use other b frames as reference for other b frames.
