Abstract: Example methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement video coding with multiple intra block copy modes are disclosed. Example video encoder apparatus disclosed herein include a coding block translator to perform a translation operation on a coding block of an image frame to determine a translated version of the coding block. Disclosed example video encoder apparatus also include a searcher to perform a first intra block copy search based on an untranslated version of the coding block and a second intra block copy search based on the translated version of the coding block to determine a candidate predictor block of previously encoded pixels of the image frame, the candidate predictor block corresponding to an intra block copy predictor of the coding block.
