Add an Intro or Outro

The intro is like a trailer, showing audiences what the video is about. The outro is the scene used to show the information about the video creator, the channel, or CTA. Those 2-4 second clips are extremely popular among YouTubers.

Intros and outros can be as simple as a background video with several words, or as complicated as designing animations in AE. In case you don't have an intro/outro at hand, here are some free templates for you to customize.

Video Boomerang

Boomerang is similar to loop. However, boomerang plays videos back and forth instead of repeating a video several times.

Instagram developed Boomerang app to make a reversed version from an existing video clip. Check out How to Create a Boomerang Video > for all details. Any video editors with a Reverse feature can also be used to create boomerang videos.

Change Video Speed

Normally, a one-second video consists of 30 frames. If you make a video play slower, they will make a frame play twice or even more. Thus, the video is longer.

FlexClip makes it possible for you to change video speed from 0.1X to 8X in just one click. To achieve better results, use the curve speed tool to gradually slow down your video.

Freeze frame is when a video stops at a still frame. It is widely used in film production to set up the style tone or enhance the narrative.
