You can adjust the video first and then open the information panel. There are many options for the effect of color matching in video layout. You select all these options, then press Ctrl+C to copy, and then go back to the timeline to select all the clips that need to change color, and Ctrl+V can be pasted. In addition, it is suggested that the color matching should be different, such as indoor, outdoor and day and night. You should classify the colors and then copy the effects to the corresponding materials.

In the transition of light and shadow, you can download a large number of light effect materials with channels from the new CG, and then put them on the time axis above the two materials, and adjust the position and transparency appropriately.
