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. Audio is not yet supported, but is planned.
- 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
- export by clicking "export"
- let video play to completion
- click "download" to grab a copy (.webm)
output:
- timeline
- allow extending beyond current max time (medium)
- split at play head (medium)
- mouseover preview safari fix (hard)
- file management
- error on bad type (easy)
- animated .gif support
- editing
- undo (hard)
- audio (hard)
- face tracking (medium/easy)
- opacity (easy)
- rotation (medium)
- code
- refactor/simplify MoveableLayer this.frames
- make video a MoveableLayer
- compress video frames
- investigate memory use warning on safari
- cache render output for thumbnails
- move height/width setting logic out of render loop
- improve text scaling logic (avoid font size, use ctx.scale)
