A collection of over 50 transition presets designed for Blender's Video Sequence Editor (VSE). Supplied as 1920x1080 image sequences, these assets function as alpha masks to blend between background and foreground video clips or still images. Each transition sequence spans approximately 48 frames. The sequences can be applied to video strips using the VSE's mask modifier, and can also be inverted or used to selectively mask effect modifiers like brightness and contrast.
