The invention discloses a video previewing method and apparatus, and belongs to the field of a computer technology. The video previewing method comprises the following steps: successively obtaining each video frame in a target video; performing special effect processing on at least one video frame in the target video to obtain each video frame corresponding to the target video after the processing; caching each video frame corresponding to the target video after the processing to a cache preview queue; and performing video previewing on each video frame cached in the cache preview queue. According to the invention, the problem in the prior art is solved that only after a special effect video is synthesized, can a terminal provide previewing of the special effect video for a user and the process consumes quite long time; and the effects of realizing the video previewing as long as each video frame corresponding to the target video after the processing is obtained and accordingly shortening the time length needed for the video previewing are achieved.
