Sharing video on WeChat is fairly easy but for some reason sharing videos on Moments is not available yet. However, there is a trick for you to share your uploaded video and send it to Moments.

1. Enter any chat room and click on the + sign at the bottom, then tap on Video.
2. Select to either Take Video to record a new video, or Choose Video to retrieve one that is already on your device.
3. Once the video is uploaded, do a long press on the video in the chat room and choose Favorite.
4. Now go to the WeChat main page and tap on the navicon and choose Favorite Messages.
5. In there, tap on the video you have just favorited then tap on the navicon and choose Send to Moments.
6. Fill the blank with your a message, and tap on Send.
