A method of real-time cropping of a real entity in motion in a real environment and recorded in a video sequence, the real entity being associated with a virtual entity, the method comprising the following steps: extraction (S1, S1A) from the video sequence of an image comprising the real entity recorded, determination of a scale and/or of an orientation (S2, S2A) of the real entity on the basis of the image comprising the real entity recorded, transformation (S3, S4, S3A, S4A) suitable for scaling, orienting, and positioning in a substantially identical manner the virtual entity and the real entity to recorded, and substitution (S5, S6, S5A, S6A) of the virtual entity with a cropped image of the real entity, the cropped image of the real entity being a zone of the image comprising the real entity recorded delimited by a contour of the virtual entity. |
