Is it correct to make videos according to grammar?

The syntax of "Video by" is not completely correct, because a necessary element is missing to form a complete phrase. If we want to express the producer or photographer of the video, we should use the format of "video was made by [creator name]", where [creator name] should be the name of a specific person or team.

For example, if we want to quote a video shot by the photographer "John Smith", we should write it like this: "John Smith's video". If you want to quote the video produced by ABC Studio, you should write it like this: "Video produced by ABC Studio".

Of course, if the producer or photographer of the video has been clearly pointed out in the context, the phrase "video by" can be simply used. For example, if we discuss the film created by a famous film director, we can say, "Have you seen the latest video of Christopher Nolan?" The "Christopher Nolan" here is enough to clearly show the producer of the video.

In short, "video by" is a common phrase, but it should be noted that the name of the producer or photographer is added to form a complete grammatical structure.

It should also be noted that in English, the preposition "by" is usually used to indicate the actor in the passive voice, so "Video by" can sometimes indicate the photographer or producer of the video. For example, in some cases, we can use "video by" to express this meaning. For example, if we see a video and want to ask who made it, we can ask, "Do you know who made this video?" The "by" here refers to the producer or photographer of the video.

In a word, the grammatical correctness of the phrase "video by" depends on the specific usage scene and context. If you want to express the producer or photographer of the video, you need to add the name of a specific person or team and pay attention to the use of the preposition "by".
