The invention discloses a director station video picture switching method and a related device. According to the scheme, the data of each input source with the original resolution is subjected to proportional adjustment and then is mixed, instead of cutting the data on the basis of a low-resolution picture and carrying out proportional adjustment on the basis of low-resolution video data in the prior art, so that the data processing efficiency is improved. According to the scheme, it can be guaranteed that the resolution of the video image displayed after stream mixing is high. Therefore, the resolution of a video picture watched by a video user is not too low after the position of the director station is changed. According to the scheme, the watching experience of the video user can be improved under the scene that the multi-camera director station carries out multi-camera video picture switching. 本申请公开了一种导播台视频画面切换方法及相关装置。本方案由于是在原始分辨率的各输入源的数据进行比例调整后混流，而非如现有技术一般地在低分辨率的画面基础上裁剪数据、在低分辨率视频数据基础上进行比例调整，因此，本方案能够保障混流
