rendering a webpage picture based on the web address, and capturing a rendered webpage picture in real time;

obtaining a captured webpage picture as webpage snapshot data; and

stopping rendering the webpage picture and stopping capturing the rendered webpage picture when an amount of obtained webpage snapshot data reaches a preset threshold.

9. The video generating method according to claim 8 , wherein capturing a rendered webpage picture in real time specifically comprises:

capturing a loaded webpage picture in real time after the webpage picture is loaded.

10. The video generating method according to claim 1 , wherein obtaining webpage snapshot data in real time is specifically: webpage snapshot data that satisfies a preset page attribute; wherein a page attribute comprises at least any one of or any combination of the following: a background color, a resolution, or an interaction mode.

11. The video generating method according to claim 1 , wherein the web address is specifically a template address; wherein the template address corresponds to a webpage template picture, the webpage template picture is generated based on a layout manner and a picture effect of a historical output video; and

the webpage snapshot data is specifically: screenshot data of the webpage template picture.

12. A server, comprising:

at least one processor; and

a memory in communication with the at least one processor;

wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform a video generating method;

wherein the video generating method comprises:

obtaining a web address;

obtaining webpage snapshot data in real time based on the web address;

selecting target webpage content from obtained webpage snapshot data; and

synthesizing a selected target webpage content with a pre-obtained input video, to generate an output video comprising the target webpage content;

the method further comprising, after obtaining webpage snapshot data and before selecting target webpage content:

selecting a target cache mode from a plurality of preset cache modes; and

caching the obtained webpage snapshot data based on a selected target cache mode;

wherein selecting target webpage content from obtained webpage snapshot data includes selecting the target webpage content from cached webpage snapshot data.

13. The server according to claim 12 , wherein synthesizing a selected target webpage content with a pre-obtained input video specifically comprises:

adjusting a transparency of each pixel in the target webpage content and a transparency of each pixel in a pre-selected input video frame to be synthesized, wherein the input video frame to be synthesized is selected from an input video; and

superimposing the target webpage content and the input video frame to be synthesized after adjusting the transparency.

14. The server according to claim 12 , wherein obtaining webpage snapshot data in real time based on the web address specifically comprises:

rendering a webpage picture based on the web address, and capturing a rendered webpage picture in real time;

obtaining a captured webpage picture as webpage snapshot data; and

stopping rendering the webpage picture and stopping capturing the rendered webpage picture when an amount of obtained webpage snapshot data reaches a preset threshold.

15. A non-transitory computer readable storage medium storing a computer program, wherein when the computer program is executed by a processor, a video generating method is implemented;

wherein the video generating method comprises:

obtaining a web address;

obtaining webpage snapshot data in real time based on the web address;

selecting target webpage content from obtained webpage snapshot data; and

synthesizing a selected target webpage content with a pre-obtained input video, to generate an output video comprising the target webpage content;
