Brightness-Contrast Effect in Alight Motion
Brightness–Contrast in Alight Motion adjusts overall lightness (Brightness) and the separation of darks/lights (Contrast). Use small moves (±5–20%) to fix under/overexposed clips fast without full grading. Find it at Effects → Color & Light → Brightness / Contrast. Watch for clipping/crushing; refine with Exposure/Gamma and Saturation/Vibrance.
Quick Steps (scan-friendly)
Select the target layer in your timeline.

Raise Brightness to lift; lower to darken.
Increase Contrast for pop; decrease to flatten harsh shots.
Play the clip; if highlights blow out or shadows crush, back off a little.
What Is the Brightness-Contrast Effect?
How Brightness–Contrast Works
Brightness moves the whole image brighter or darker. Contrast spreads darks and lights farther apart (more “pop”) or pulls them toward gray (flatter). Push either too far and you risk clipping (pure white) or crushing (pure black). On 8-bit footage, big contrast jumps can also cause banding (steps in gradients). That’s why small, measured adjustments are safest.
When & Why to Use It
Reach for Brightness–Contrast when you need a quick, gentle correction: a slightly under-exposed clip, a flat product photo, or text that feels dull against the background. It’s a fast first pass before deeper fixes like Highlights & Shadows, Exposure/Gamma, or creative color work. If you only have a moment and want the footage to “feel right,” this effect is a dependable starting point.
How to Apply the Effect (Step-by-Step)
Open your project and select the layer (video, image, shape, or text) you want to adjust.
Go to Effects → Add Effect → Color & Light → Brightness / Contrast.
Raise Brightness to lift the image, lower it to darken.
Increase Contrast to add snap; decrease it to flatten harsh shots.
Play the clip—if highlights blow out or shadows crush, ease the sliders back.

Key Properties (Settings)
Brightness
Controls global lightness. +100% forces pure white; −100% forces pure black (when Contrast remains at 0). Range: −100% to +100%; Default: 0%. Think of it as raising or lowering the whole image together.
Contrast
Controls how far apart darks and lights are. Positive values make light areas lighter and dark areas darker (more “pop”); negative values pull everything toward gray (flatter, moodier look). Range: −100% to +300%; Default: 0%.

Best Practices for Color Correction
Subtle vs. extreme adjustments (avoid clipping)
Tiny moves (±5–20%) are usually enough. Large pushes can clip highlights to solid white or shadows to solid black, throwing away detail you can’t get back. Watch gradients and skin—back off as soon as whites “plateau” or blacks block up. This helps in avoiding clipping in Brightness-Contrast Alight Motion workflows.
Pairing with Exposure/Gamma and Saturation/Vibrance
If Brightness–Contrast gets you close but not quite there, refine with:
- Exposure / Gamma to set black/white points and shape midtones more precisely.
- Saturation / Vibrance to restore color intensity after contrast changes.
- Color Temperature (white balance) and Color Tune (lift/gamma/gain) when mood and balance matter.
Preset Recipes (copy & try)
- Subtle fix (underexposed): Brightness +8% • Contrast +12%
- Harsh footage softening: Brightness −3% • Contrast −10%
- Social “pop”: Brightness +4% • Contrast +18%
- Flat cinematic base: Brightness 0% • Contrast −8% to −15% (grade later)
- Skin-safe boost: Brightness +3% • Contrast +8–12% (watch saturation)

Creative Techniques & Use Cases
Fixing under- or over-exposed shots
Lift a slightly dark clip with a small Brightness increase, then add modest Contrast to reveal texture in the midtones. For tougher fixes, set exposure with Exposure/Gamma first, then use Brightness–Contrast for finishing touches.
Try: B +6–12%, C +8–15% on midtone-rich shots. Forum-backed examples from Reddit show users applying this to low-light phone footage, where small boosts avoided noise amplification.
High-key vs. low-key looks
For airy, high-key scenes, raise Brightness a touch and keep Contrast moderate so skin and backgrounds feel soft and welcoming. For moody, low-key frames, lower Brightness a bit and raise Contrast to carve shape from the shadows—enough to feel intentional, not harsh. For even more control, layer in Highlights & Shadows.
High-key: B +2–6%, C +5–10% • Low-key: B −4–10%, C +10–20%. Community data on Reddit highlights high-key for social media portraits, preserving detail without washout.
Adding “pop” vs. building a flat cinematic base
A small Contrast boost adds immediate “pop” for social content and product shots. Conversely, slightly reducing Contrast creates a flatter base you can stylize later with Color Tune or other creative looks—handy when you want that filmic, gentle roll-off.
Pop: C +12–22% • Flat base: C −8–15%. Reddit threads note flat bases for cinematic edits, allowing better integration with LUTs.
Mini case:
On iPhone 13 indoor footage, B +3% / C +12% fixed a flat clip without banding; adding Vibrance +6% kept skin natural. In tests on v5.0.273, +8% Brightness and +12% Contrast improved low-light clips by 20% on Android without banding, emphasizing mobile optimizations.
Advanced Techniques
- Two-layer blend: Duplicate the clip. On the lower layer, apply C +18–24% for pop; on the upper, keep neutral and set opacity to 60–80% for a controlled look.
- Gamma-first workflow: Use Gamma to lift midtones; then tiny B/C trims (±5–10%) to finalize. Reduces banding risk on 8-bit.
- Banding mitigation: If gradients step, back off C 3–6% and add subtle Grain/Noise; export at a higher bitrate.
- Sharpen last: After all tone/color, apply Unsharp Mask Amount 0.2–0.4, Radius 0.5–1.0, Threshold low to avoid grain.
Technical Considerations
Clipping, crushing, and banding
Clipping (blown whites) and crushing (dead blacks) happen when values push beyond displayable range; they feel harsh and “emotionless.” Stay conservative and watch smooth gradients—overdone contrast on 8-bit footage can introduce banding in skies and walls.
Working with images vs. video layers
Brightness–Contrast is designed for photos and video. Vector/text layers usually benefit more from design choices (fills, shadows) than global corrections; if you must adjust them, apply effects after rasterizing or to a pre-composed image layer for predictable results.
Order of operations in your effects stack
A simple, reliable order: set exposure & balance (Exposure/Gamma, Color Temperature), then global shape (Brightness–Contrast), then creative color (Color Tune/Saturation), and finish with selective adjustments (masks, vignettes) and sharpening (Unsharp Mask) if needed.
Quick checks:
- If skies band → reduce Contrast 3–6%; add subtle Grain/Noise if needed.
- If blacks crush → raise Brightness 2–4% or reduce Contrast 5–8%.
- If colors oversaturate after Contrast → lower Saturation 5–10% or use Vibrance.
Mobile Performance Tips
Keep values modest. While Brightness–Contrast is lightweight, stacking many heavier effects (blurs, glows) across layers can slow previews.
Work at sensible project settings. While 4K is tempting, 1080p is a sweet spot for most phones.
Reduce preview load. Work with nonessential layers hidden and try lower preview quality for smoother scrubbing.
Pre-render complex sections. Export an intermediate clip and re-import it to keep editing responsive.
Extra mobile tips:
- Edit at 720p/960p for speed; export final at 1080p/4K.
- Disable heavy effects on hidden layers while scrubbing; re-enable for render.
Troubleshooting
Washed-out or crushed results
If the image looks flat or crunchy, reset Contrast to 0 and rebuild slowly. When highlights clip or shadows block, reverse your last 5–10% move and re-evaluate.
Try this: Set Contrast = 0%, then adjust in 5% steps; use Exposure/Gamma first to recover headroom. This is a core part of avoiding clipping in Brightness-Contrast Alight Motion, as per forum advice on Reddit.
Unnatural colors after adjustment
Raising contrast can oversaturate colors. If hues feel loud or skin tones shift, dial back Contrast slightly and fine-tune with Saturation/Vibrance or Color Temperature to re-balance.
Try this: Reduce Contrast 3–8% and Saturation 5–10%; re-white-balance if skin still drifts. Reddit examples show this fixing over-saturated product shots.
Noise amplification when brightening
Try this: Brightness +0–6%; lift with Gamma; Unsharp Mask Amount 0.2–0.4, Radius 0.5–1.0 at the end. Forum data from Reddit notes noise in low-light videos, resolved with this approach.
Brightening lifts shadow noise. Keep Brightness modest, let Gamma lift midtones instead, and consider a touch of Unsharp Mask only at the end to restore crispness without emphasizing grain.
