These past few projects had me obsessing over how to make digital footage look like it came out of an old set-top box. For the easiest route, I often reach for Boris FX Continuum — it has dedicated scanline/CRT-style filters that emulate the thin horizontal lines and let you control intensity, frequency, and blend. Sapphire (also from Boris FX) includes variants and extra glow/chroma tools that make the scanlines feel organic rather than overlaid. Red Giant Universe (the 'VHS' and glow-esque tools) can give a quick retro vibe too, though I usually tweak its output with additional grain and a slight blur.
If you want free or DIY options, in After Effects I make a 1px-high repeated pattern layer (or use 'Venetian Blinds' with high feather/low width) and set it to multiply or overlay, then add a subtle gaussian blur and a curve warp for CRT curvature. In Resolve you can make the same effect with a repeated matte or an OpenFX generator. For live or shader-based work, GLSL shaders or OBS shader packs can do scanlines and curvature on the fly. My rule: pair scanlines with slight bloom, chromatic aberration, and film grain so they feel part of the image, not pasted on — that little combo always sells the look for me.
I've piled together a bunch of tricks over the years, and for straight-up scanlines I reach for a mix of commercial plugins and simple overlays depending on the job. If I want a one-click, polished CRT look that plays nicely in Premiere, After Effects, Final Cut, or Resolve, Boris FX Continuum and Sapphire are my go-tos — they both include analog/CRT modules that can add scan lines, jitter, and bloom without fuss. Red Giant Universe (now under Maxon) and Video Copilot's 'Twitch' also help if I want chromatic breakup and flicker combined with line patterns.
When I'm on a budget or in a hurry, I often make a repeatable stripe texture (thin black lines on a transparent background) and layer it over the footage using Multiply or Overlay, animating the opacity/vertical position for a scanline sweep. Fusion in DaVinci Resolve and AE's Venetian Blinds or pattern generators let me create procedural scanlines so I can change size, softness, and animation on the fly. OBS and streaming rigs get similar results with shader filters (CRT/scanline shaders) or the 'obs-shaderfilter' plugin.
For Final Cut I sometimes pick up packs from Pixel Film Studios or MotionVFX for quick presets, and HitFilm has built-in TV/distortion effects that work well. My personal trick is to combine mild blur, subtle grain, and thin scanlines rather than a heavy overlay — it feels more authentic to my eye.
On a more technical night I'm picky about how scanlines map to pixel grids. For pixel-perfect, create a single-line matte (1–2px tall) and repeat it so the line spacing matches your target resolution; in 1080p I often use 1px line, 2–3px gap for subtle lines, while for 4K the spacing scales up. Plugins like Boris FX Continuum or Sapphire speed this up and give motion-blur-friendly options, but for ultimate control I use After Effects: animate the pattern's vertical offset by half a pixel per field to fake interlacing, add a displacement map to introduce slight curvature, then layer on a glow and vignette. For realtime workflows, GLSL/ShaderToy shaders or OBS shaders replicate scanlines and curvature efficiently. If you want an authentic CRT, also simulate phosphor bloom with a horizontal blur and add a soft temporal lag — those details make the lines feel alive, not flat to me.
When I want fast results I pick two paths: a plugin suite or a handcrafted layer. The plugin route means Boris FX Continuum or Sapphire for polished scanline controls; Red Giant Universe is great for quick retro vibes. The DIY route is making a black-and-transparent striped pattern, scaling it to match your footage, setting blending to multiply or overlay, then adding a slight blur and film grain. Also consider adding a tiny bit of chromatic aberration and a curve warp to sell the CRT feel — those little touches change everything in my edits.
I've always loved the mojo a subtle set of scanlines adds to footage — it’s like a tiny texture that suggests a whole era. My quick go-to recommendations: Boris FX Continuum and Sapphire for professional, tweakable results; Red Giant Universe for quick retro presets; Pixel Film Studios for Final Cut users who want plug-and-play; and Video Copilot's tools (Twitch, etc.) when I want glitch plus lines. When I can't use paid plugins, I build a repeating matte in After Effects or Resolve, use multiply/soft light blending, scale the opacity down, and then add grain, slight chromatic aberration, and a curvature warp. It’s amazing how those few steps transform clean footage into something warm and nostalgic — I still grin every time it works.
My late-night editing experiments ended up teaching me the cheapest and the priciest ways to get scanlines. If you're fine paying, Boris FX Continuum and Sapphire are my favorites because they offer precise controls — density, falloff, and the ability to keyframe scanline movement to mimic interlaced roll. Red Giant Universe has some handy retro tools like 'VHS' that include line-related artifacts; they’re quick and pretty GPU-friendly.
For Final Cut Pro users, Pixel Film Studios sells a bunch of scanline and CRT presets that work well if you want a one-click look. DaVinci Resolve accepts OFX plugins (so Continuum and Sapphire plug in there too). If you want to avoid plugins, create a repeating matte or use the 'Venetian Blinds' or 'Grid' effects in After Effects, set it to soft light or multiply, lower opacity, and add a tiny blur. Layer subtle noise and flicker to simulate phosphor persistence — that mix always reads as believable to me.
If I'm messing around on a tight schedule and want old-school TV vibes, I'll grab a plugin suite that already has scanline presets. Boris FX Continuum has solid CRT/scan emulation that works across most NLEs, and Red Giant Universe gives quick VHS/retro tools that include line-like artifacts. For After Effects, Video Copilot's 'Twitch' is an easy add-on to get jitter and slicey movement that pairs nicely with a line overlay.
When I don't want to buy anything, I just make a tiny repeating stripe PNG (2–4px black line, transparent gap) and scale it up in the editor, then set the blend mode to Multiply or Overlay and add a touch of motion. Resolve's Fusion and AE let you generate scanlines procedurally if you prefer nodes over images. For streaming, OBS shader filters offer CRT/scanline shaders that look surprisingly good in real time. I usually tweak opacity and blur until it feels right for the scene.
I tend to approach scanlines from a more technical angle: if you want maximum control, look for shader-based or node-based solutions. In Resolve's Fusion you can create a 'Grid' or 'Rectangle' pattern and drive it with a sine or noise node to emulate moving scanlines, then composite with a luma matte. That gives you precise control over thickness, spacing, and temporal behavior. For a premade option, Boris FX Continuum and Sapphire include analog/CRT modules that expose parameters for line intensity, curvature, and chromatic offsets across hosts like After Effects, Premiere, Final Cut, and Resolve.
On the plugin side, Red Giant Universe has useful retro effects (VHS-style) while Video Copilot's 'Twitch' is excellent for slice-based temporal distortion; combine either with a thin stripe overlay for classic scanlines. If you're into live work, OBS supports shader filters via 'obs-shaderfilter' and community CRT shaders—great for streaming overlays. For Blender, use a Wave or Brick texture in the compositor plus a Mix node and motion to simulate scanline roll. I like this mix of procedural and plugin tools depending on whether I need speed or precision.
Lately I've been favoring simple, effective approaches: buy a robust suite if you need consistency, or make your own stripes if you want flexibility. Commercial suites like Boris FX Continuum (and Sapphire) give dedicated CRT/scanline effects and are compatible across most editors; Pixel Film Studios and MotionVFX sell convenient packs for Final Cut users. For those who prefer in-editor work, After Effects' Venetian Blinds or Resolve's Fusion nodes can produce authentic scanlines when paired with subtle blur and grain.
For streaming setups, community shaders for OBS handle scanlines well in real time. My favourite quick workflow is a thin striped PNG overlay plus mild chromatic aberration and film grain — it’s cheap, fast, and surprisingly convincing. Overall, I like keeping the lines subtle so footage breathes, and that little tweak usually sells the effect for me.
