description The invention relates to a microphone-connected live broadcast video image rendering method and apparatus, and a video live broadcast system. The method comprises the steps of obtaining a background texture of a background image and a background special effect parameter thereof; obtaining a foreground texture of a to-be-rendered microphone-connected anchor image, a synthesis parameter of the foreground texture and a foreground special effect parameter; synthesizing the foreground texture to the background texture according to the synthesis parameter to obtain a temporary picture; rendering the special effect content on the temporary picture according to the foreground special effect parameter and the background special effect parameter to obtain a virtual same-station composite image; according to the technical scheme, the virtual same-channel scene is firstly rendered on the unified background image, so that the consistency of background pictures is ensured, and the visual effect of video image rendering in
