Video synthesis method and video synthesizer

The invention provides a video synthesis method and a video synthesizer, and a target text and a video material can be automatically matched through the video synthesizer so as to quickly determine a target video material. Meanwhile, when the video synthesizer determines the target video material, the matching degree between the texts corresponding to different content categories in the target text and the label of the video material and the matching degree between the text abstract of the target text and the description text of the video material are comprehensively considered, the determined target video material is ensured to accurately correspond to the content of the target text, so that the target video synthesized by the target video material can accurately display the content to be expressed by the to-be-processed text. 本申请提供了一种视频合成方法及视频合成器，通过视频合成器可以自动匹配目标文本与视频素材，以快速确定目标视频素材。同时，视频合成器在确定目标视频素材时，综合考虑了目标文本中对应不同内容类别的文本与视频素材的标签的匹配度，以及目标文本的文本摘要与视频素材的描述文本的匹配度，以确保所确定的目标视频素材与目标文本的内容准确对应，进而可以保证由目标视频素材合成的目标视频可以准
