Rafii Builds · free tool
Every transition here is drawn by maths in your browser, then recorded into a real video file — so you can have any colour, any speed, any resolution, and never pay for a pack again. Nothing uploads. Nothing is AI. Nothing expires.
The safe pick for CapCut, VN, InShot and any phone editor. Put the clip on a layer above your footage and apply chroma key / remove background on the green.
Black & white version for Premiere, DaVinci Resolve and Final Cut. Use it as a track matte / luma key — white reveals, black hides. Cleanest edges of the four.
One video file with a real alpha channel — QuickTime Animation, the format editors have taken for decades. Drop it on the track above your footage in DaVinci, Premiere, Final Cut or After Effects. No keying, lossless, no noise.
Alpha video for browsers, OBS overlays and web players. Desktop editors decode WebM alpha badly (speckled black noise) — reach for the MOV there instead.
Shape on black. Handy as a stinger between two cuts, as a luma source in editors that key on brightness, or when you just want a solid colour swipe.
No account, no watermark, no transition pack to buy. If Transition Bin saved you a subscription, you can put a coffee toward the next free tool — completely optional, and everything here works either way.
