Abstract
A method and device for editing video data to achieve a video effect in a video sequence. From an encoder, transform coefficients of part of the video sequence are obtained. The transform coefficients are mixed with other transform coefficients in a combining module. The output of the combining module is quantized and further processed to provide an edited video bitstream. In the combining module, transform coefficients are multiplied with weighting parameters to achieve different video effects. Furthermore, logo data from a memory can be transformed into further transform coefficients for mixing in order to achieve a logo insertion effect. Moreover, prediction error and motion compensation information obtained from video data can be used to provide a reference frame, and the transform data from the reference frame can be used for mixing to achieve a blending effect.
