Twenty seamless 10-second particle loops at 24 fps, built as drop-on overlays. Landscape 3840×2160 and vertical 1080×1920. Each effect ships as VP9 WebM with straight (not premultiplied) alpha, and as H.264 on black.

What’s included

• 20 effects × 4 files each (80 video files across 4 zips)
• 4K-WebM-alpha.zip — 3840×2160, VP9, straight alpha
• 4K-H264-on-black.zip — 3840×2160, H.264, additive on black
• Vertical-WebM-alpha.zip — 1080×1920, VP9, straight alpha
• Vertical-H264-on-black.zip — 1080×1920, H.264, additive on black

The 20 loops

• embers_rise — rising campfire embers with hot gold cores and cooling orange
• embers_wind — the same ember look, blown sideways
• snow_light — sparse soft flakes, near flakes go to bokeh
• snow_heavy — 2–3× the flakes of snow_light, larger near flakes
• snow_blizzard — diagonal gusts and streaked near flakes
• sparks_weld — grinder/weld shower: tiny near-white heads, thin orange motion-blur tails, gravity arcs, floor bounce
• sparks_campfire — sparks lifting from a fire
• dust_motes — fine drifting motes
• dust_godray — a golden sun-shaft with dust inside it
• dust_interior — window-lit interior motes, bright enough to read, still airy
• bokeh_gold — champagne lens discs
• bokeh_teal — teal / cyan discs
• bokeh_city — night-city discs (amber, cool white, red, teal)
• lightleak_amber — warm film-gate burn
• lightleak_rose — rose / magenta leak
• lightleak_prism — organic spectral wash, not RGB bars
• fireflies — 25–40 pulsing yellow-green glows on wandering paths
• pollen — yellow-green spring grains
• ash — pale falling ash with a few still-glowing cinders
• petals — tumbling cherry-blossom petals (notched pink-white, 3D flip)

How to use

WebM: interpret alpha as straight. For embers, sparks, fireflies, leaks and bokeh you can also use Add or Screen. H.264-on-black: Add or Screen over your shot. Each file is a 10-second loop — extend it on the timeline and it wraps.

RGB never carries a dark halo. These will not punch black boxes into your footage.

Not included

Music, NLE project files, After Effects templates, or the listing mockup photographs.
