Video data encoding and video encoder configured to perform the same

An electronic system comprising:

• a memory storing a program of instructions;
• and
• a processor configured to execute the program of instructions to
• provide a plurality of input pictures, and
• encode the plurality of input pictures, the encoding including
• receiving the plurality of input pictures,
• outputting the plurality of input pictures as a plurality of subgroups of one or more input pictures, a size of each subgroup being smaller than a size of a group of pictures (GOP),
• generating, for each given subgroup, a plurality of candidate encoded groups associated with the given subgroup based on encoding one or more input pictures included in the given subgroup multiple times according to separate, independent encoding schemes,
• storing the plurality of candidate encoded groups in a plurality of buffers,
• selecting, for each given subgroup, one candidate encoding group, of the plurality of candidate encoded groups associated with the given subgroup, as a plurality of encoded pictures associated with the given subgroup based on comparing at least one coding parameter, of coding cost and coding quality, of the plurality of candidate encoded groups associated with the given subgroup with each other, and
• generating a video display based on the selecting, the video display including the pluralities of encoded pictures associated with the plurality of subgroups, respectively.
