Abstract: According to examples of the presently disclosed subject matter, a method of controlling a video content system can include: obtaining a current input frame and a preceding input frame from an input video sequence and obtaining a current degraded frame and a preceding degraded frame from a degraded video sequence corresponding to the input video sequence; computing a first differences value from the current input and the preceding input frames and a second differences value from the current degraded frame and the preceding degraded frame, comparing the first and second differences values, giving rise to an inter-frame quality score; computing an intra-frame quality score using an intra-frame quality measure that is applied in the pixel-domain of the current degraded frame and the current input frame and providing a configuration instruction to the video content system based on a quality criterion related to the inter-frame and the intra-frame quality scores.

Abstract: There is provided a computerized method and system of optimized video encoding of an input video sequence corresponding to a plurality of input frames, the method comprising: obtaining an input frame; performing a first encoding of the input frame using a first encoding parameter determined in accordance with a target bit-rate, giving rise to a first encoded frame; performing a second encoding of the input frame using an iterative quality-driven encoding scheme initialized with an initial second encoding parameter, the initial second encoding parameter determined based on the first encoding parameter, the second encoding performed in an attempt to seek a second encoded frame having a lower bit-rate than the first encoded frame and meeting a quality criterion relative to the first encoded frame; and in case of the second encoded frame being found, providing the second encoded frame as an output frame corresponding to the input frame.
