mebm is a browser based video editor that supports animation of images and text overlays. The animation is done with key-frames (denoted in blue on the timeline) and linear interpolation.

The design values simplicity and rudimentary functionality over a full feature set.

usage

• space to pause/play
• select layers to manipulate them (click on the timeline or sidebar)
  • shift + scroll or pinch to zoom text and images
  • drag to move them
  • arrow keys to jump between keypoints
  • backspace to remove keypoints
• import
  • by dragging in videos images or audio files
  • by clicking "+ media"
  • by pasting URLs to hosted media (only some domains)
• export by clicking "export"
  • let video play to completion
  • click "download" to grab a copy (.webm)
