Methods and systems are presented for transforming frames of a video. The method provides an object in the video that at least partially and at least occasionally is presented in frames of a video. An object is detected in the video. Detection of the object comprises detecting feature reference points of the object. The object is tracked in the video. The tracking comprises creating a mesh that is based on the detected feature reference points of the object and aligning the mesh to the object in each frame. A first set of node points is generated on the mesh based on a request for changing proportions. A second set of nodes points is generated based on the first set of node points. The frames of the video are transformed in such way that the object's proportions are transformed in accordance with the second set of the node points using the mesh.
