Video overlay effects that setthe whole mood
Glitch, noise, sparkles, grain — composited over the full frame in a click. Or bring the overlay pack you already own and drop your own clips straight in.
How to use the video overlay effects in three steps
Overlays are the cheapest way to give a video a point of view. A grain pass makes a phone clip look shot on film; a glitch pass makes a tech explainer feel urgent. Shorz ships a set, lets you import the packs you've already bought, and composites them over the finished frame — after B-roll, captions and titles, so the look sits on top of everything.
Pick an effect
Browse the bundled overlays — glitch, noise, sparkle, grain — and preview them against your actual footage rather than a demo reel.
Preview on your own video
Or import your own
Already own an overlay pack? Import your clips and they appear alongside the built-ins, reusable across every project from then on.
Bring your own pack
Stack and export
Select more than one and they composite together. Selecting an overlay turns the effect on automatically, and clearing the selection turns it back off — no orphan switches.
Composited over everything
Find it in the app under Overlay panel.
Why Video Overlay Effects in Shorz
Effects that don't fight the edit
The overlay renders above B-roll, subtitles and titles, so a grain or glitch pass unifies the whole frame instead of sitting under half of it. It's the last layer, which is where a look belongs.
Top layer
Free, local and unlimited
Overlays are drawn at render time on your own machine, so they cost no credits and work in full on a free Auto Edit or Clipping run. Use them on every video without thinking about the bill.
No credits

Video Overlay Effects questions
Yes. Import your own overlay videos and they sit in the library next to the bundled ones, available in every project.
Yes, selections stack. Choosing an overlay turns the effect on automatically, and clearing the selection switches it off again.
No. They're composited locally at render time, so they're free for everyone including on free Auto Edit and Clipping runs.
The overlay is the top layer, so it sits over B-roll, subtitles and titles — that's what makes a grain or glitch pass unify the whole frame. Most bundled effects are semi-transparent by design.
