A video generation method includes: when a video theme configured by a user and a video production instruction are obtained, obtaining, according to the video production instruction, a user image and multiple video templates matching the video theme; embedding the user image into reserved positions of at least some of the video templates so that the user image is combined with situational materials of the video templates to generate at least one video; obtaining a video to be published from the at least one video, and publishing the video to be published to a preset video playback platform. Thus, during the process of video production, at least one video can be generated at a time as long as the user image is embedded into multiple video templates, without repeatedly photographing by a user.

The present invention provides a low viscosity poly-&#x3b1;-olefin lubricating oil and a synthesis method thereof. The method comprises: (1) the &#x3b1;-olefin raw material is subjected to dehydration treatment so that the water content in the raw material is &#x2264;10 ppm; (2) a reaction of the dehydration treated &#x3b1;-olefin raw material is carried out in the presence of a complex catalyst and gaseous BFto obtain a reaction product, wherein the pressure of the gaseous BFis 0.01 to 1 MPa; (3) the reaction product obtained in step (2) is sequentially subjected to flash distillation, gas stripping, centrifugation, and washing treatment to obtain an intermediate product; (4) the intermediate product obtained in step (3) is subjected to distillation under reduced pressure to separate the unreacted &#x3b1;-olefin raw material and &#x3b1;-olefin dimers, and the remaining heavy fractions are subjected to hydrogenation saturation treatment followed by fractionation and cutting-off.
