Disclosed are a transcoding method and apparatus. The method includes: selecting a first definition and a second definition from multiple levels of definition, and determining a first resolution and a second resolution that respectively correspond to the first definition and the second definition; transcoding a first part of content of a media file based on the first resolution and the second resolution and according to a preset transcoding rule, and recording a first real-time quantization parameter (QP) value and a second real-time QP value in the transcoding process; determining whether the first real-time QP value and the second real-time QP value meet a preset detection rule; if the determining result is no, adjusting the first resolution and/or adjusting the second resolution; and transcoding the non-transcoded part in the media file according to the adjusted first resolution and/or second resolution. The transcoding method and apparatus provided by example embodiments of the present disclosure may increase the transcoding speed of a media file.
