Why Should We Trim Videos
In what circumstances do we need to apply the video trimming function to our videos? Here are some situations:
Start trimming
Cut off unnecessary startup preparation shots, such as some pauses and blank frames which may increase the audience’s waiting time to enjoy the videos.
End trimming
Remove invalid frames at the end of the video to avoid dragging and make the end part of the videos smooth and efficient, so as to optimize the video contents.
Time control
If your videos need to be restricted to a duration limit, you can also adopt this method to delete the redundant part in the beginning and ending clip.
Moment highlight
If your shooting purpose is to show only those wonderful moments to the audience, then you can capture the corresponding duration you want by trimming unnecessary contents.
