Zusammenfassung:	Methods and apparatuses for encoding/decoding a video are provided. A picture from a video is decoded from a bit-stream, the picture being encoded in the bitstream at a resolution that is lower than an original resolution of the picture. Decoding the picture further comprises up-sampling the decoded picture to the original resolution, and applying an adaptive filter to at least one component of the up-sampled decoded picture. According to some embodiments, the adaptive filter may be performed in-loop or out-of-loop of the decoding/encoding process.
