In the latest version of WhatsApp for Android, you can edit videos before you send them. With a simple trim tool, you’re able to select a particular section of your video in a few easy steps.
1. Record video with WhatsApp
Select a contact and then tap the paperclip icon in the top right corner. Select the video icon. Then click on Video Camera to record a video or on the gallery icon to edit an existing video.
2. Edit your video
This opens the WhatsApp video editor. Using the blue guides, you trim the clip. Move each of the blue arrows to the left or right to set the start and end of the video. Or you can move the entire blue line to select the section of the video you want.
Once you’ve finished the selection, send your video by clicking Send.
