Should I enable frame reordering?
Frame reordering is the concept of allowing frames to be decompressed in a different order than their display order. For almost all cases, leave this box checked for H. 264 encoding. The only time you would uncheck this box is if you are creating an H.
Why are I-frames inserted into the compressed output stream relatively frequently?
I-frames are inserted into the output stream relatively frequently. I-frames are used as access points for random access and FF/FR functionality in the bit stream. in the target frame are compared on a pixel-by-pixel basis with the contents of the reference frame to find a best-matched block of equal size.
Why are I-frames relatively often inserted into the MPEG GOP compression structure?
I-frames are generally inserted to designate the end of a GOP (Group of Pictures) or a video segment (refer to our article on ABR streaming fundamentals). Because I-frame compression is not dependent on previously-encoded pictures, it can “refresh” the video quality.
Which frame in video compression is presented at regular interval?
In regards to video compression for live streaming, a keyframe is set inside the encoder. This is configured by an option sometimes called a “keyframe interval” inside the encoder. The keyframe interval controls how often a keyframe (i-frame) is created in the video.
