c# - Images that are H264 encoded should be encoded again? What are key frames -


i have images h264 encoded. have generated video these images. need encode video again h264? , keyframes?

you might want re-check encoding of individual images -- h.264 defined video, not individual still images.

once you've created video, h.264 encoding make sense. in particular great deal of compression h.264 motion prediction -- i.e., encode block in 1 frame based on similar block in previous frame (or can use bidirectional prediction, it's based on both previous , subsequent frame).

a key frame 1 isn't predicted other frames (i.e., i-frame) that's used let picking video in middle of transmission synchronized , have basis other frames it's going receive.
