1. A video synthesis method, comprising:
acquiring a first video;
capturing second video data photographed in real time;
performing first encoding on the second video data to obtain an encoded video, wherein the performing first encoding on the second video data to obtain an encoded video further comprises: encoding the second video data in real time by adopting a first entropy encoding mode to obtain the encoded video;
synthesizing the first video and the encoded video to obtain synthesized video data; and
performing second encoding on the synthesized video data to obtain a target video, wherein the performing second encoding on the synthesized video data to obtain a target video further comprises: encoding the synthesized video data in non-real time by adopting a second entropy encoding mode to obtain the target video, wherein the first entropy encoding mode is different from the second entropy encoding mode,
wherein, an encoding speed of encoding the synthesized video data in non-real time is lower than an encoding speed of encoding the second video data in real time.
