When editing a video, in order to obtain the appropriate length of the video material, you can use the dot method to intercept it. The specific steps are as follows:

Find the material that needs to be intercepted: First, find the part of the material you need in the video and locate the location that needs to be intercepted.

Use the dot function: Use the left mouse button to click the dot function on the video progress bar. Usually this function will be marked as a small dot, triangle or symbol. Marking points can help you quickly mark the start and end points of the video part that needs to be intercepted.

Set the starting point: Set the starting point of the video material by left-clicking the point function on the player.

Set the end point: Move the player progress bar to the end point of the video material, and use the left mouse button to click the start or end point to set the end point of the video material.

Intercepting the material: After finishing editing, you can use tools such as video editing software to intercept the material and cut it according to the length of the material you need.

It should be noted that when intercepting material, you should ensure that the length of the material you intercept can meet your needs. If the length of the material is too short, it may result in incomplete or incoherent content. On the contrary, if the length of the material is too long, it will also affect the charm of the video and should be appropriately cropped as needed
