How to Fix Underexposed Video

Part 1. What Is an Underexposed Video?

An underexposed video is footage recorded with insufficient exposure, causing the overall image to appear darker than intended. Important details, especially in shadow areas, may be difficult to see.

An underexposed video is more than simply a "dark video." A video can look dark because of intentional lighting or artistic choices, while underexposure usually means the camera did not capture enough light for the scene. Severe underexposure can also result in lost shadow details, increased noise, and dull colors.

How to Tell If a Video Is Underexposed

You can usually identify an underexposed video by looking for several signs:

• The overall image is too dark: The main subject may not stand out from the background.
• Faces are difficult to see: Facial features may become unclear, especially in indoor or nighttime footage.
• Shadow details are missing: Dark areas may appear completely black instead of showing textures or objects.
• The video looks dull: Colors can appear less vibrant when there is not enough exposure.
• Brightening reveals noise: Increasing exposure may make grain and digital noise much more noticeable.

Why Do Videos Get Underexposed?

Underexposure can happen for several reasons, including:

• Insufficient lighting: The scene does not provide enough light for the camera sensor.
• Incorrect exposure settings: A low ISO, fast shutter speed, or narrow aperture can subject reduce the amount of light captured.
• Strong backlighting: A bright window, sunset, or light source behind the subject can cause the foreground to become too dark.
• Nighttime shooting: Low-light environments make it harder to capture enough exposure without introducing noise.
• Automatic exposure errors: A camera may prioritize a bright background and leave the main subject underexposed.

Part 2. 6 Tips to Fix an Underexposed Video

You can correct an underexposed video with traditional editing software such as Adobe Premiere Pro, DaVinci Resolve, or Final Cut Pro. These tools let you manually adjust exposure, brightness, shadows, contrast, and highlights.

For mild underexposure, basic color adjustments may be enough. For darker footage, however, you may need to combine several adjustments and reduce the noise that becomes visible after brightening.

1. Increase Exposure and Brightness

The first step is to increase the overall brightness of the footage. Most video editing tools provide controls such as Exposure, Brightness, or Lightness.

Start with a small adjustment rather than pushing the brightness too high. Increasing exposure gradually can reveal details in darker areas while maintaining a natural appearance.

A practical approach is:

• Open the color correction or adjustment panel.
• Increase Exposure slightly.
• Check the subject's face and other important details.
• Adjust Brightness if the image still looks too dark.
• Compare the result with the original footage.

Avoid simply maximizing the brightness slider. Excessive brightening can make the video look flat and can cause noise, washed-out colors, and unnatural skin tones.

2. Lift Shadows and Adjust Contrast

Boosting the shadows specifically reveals hidden details in dark background areas without blowing out bright elements. Lowering the contrast slightly prevents midtones from looking harsh and helps smooth out tonal transitions across the scene.

How to Adjust: Increase the Shadows and Blacks sliders while slightly reducing the overall Contrast.

3. Adjust Highlights and Whites

Brightening an underexposed video can create a new problem: some already-bright areas may become overexposed.

For example, a scene containing a window, lamp, sky, or reflective surface may have both very dark and very bright areas. After increasing exposure, these highlights can lose detail.

Use Highlights and Whites to control these areas:

• Lower Highlights if bright areas look blown out.
• Adjust Whites to control the brightest parts of the image.
• Keep enough brightness to maintain a natural look.
• Check faces and other important subjects after every adjustment.

4. Reduce Noise

Noise is one of the most common problems when fixing an underexposed video. Dark footage often contains digital noise, and brightening the image can make that noise much more obvious.

Use your editor's Noise Reduction or Denoise controls after adjusting exposure. Apply noise reduction carefully because excessive processing can make faces, textures, and fine details look soft.

5. Correct the Color

Exposure adjustments can sometimes make colors look washed out or unnatural. After brightening the video, check its White Balance, Temperature, Tint, Saturation, and Vibrance.

For example, an indoor video may have a strong yellow or blue cast. Correcting the white balance can make skin tones and neutral objects look more natural.

Avoid increasing saturation too much. When an underexposed video is heavily brightened, oversaturated colors can make the footage look artificial.

6. Use Curves for More Precise Exposure Control

For more control, use the Curves tool instead of relying only on brightness and exposure sliders.

A typical RGB curve allows you to selectively brighten different tonal ranges. You can gently raise the darker portion of the curve to recover shadow details while keeping the brighter portion relatively stable.

This approach is useful when:

• The subject is dark but the background is already bright.
• You want to preserve highlights.
• You need more precise control over contrast.
• Basic exposure adjustments make the entire frame too bright.

Part 3. The AI Solution: Fix Underexposed Videos and Recover Details

Manual color correction works well for moderately underexposed footage, but it has limitations. When a video is dark, noisy, blurry, and low-resolution at the same time, simply increasing exposure may reveal noise without restoring the details you actually want to see.

This is where an AI video enhancer can provide another approach.

HitPaw VikPea uses AI-powered video enhancement to improve footage that needs more than basic brightness correction. It can help enhance dark and low-light videos, reduce noise, improve clarity, and recover visual details. It can also upscale low-resolution footage to higher resolutions, including 4K and 8K, depending on the source and selected model.

Key Features for Underexposed Videos

• Low-light enhancement: Improve dark footage and make important subjects easier to see.
• Noise reduction: Reduce grain and noise that may become more visible after brightening.
• Detail recovery: Enhance facial features, textures, and other important visual details.
• Video upscaling: Improve low-resolution footage and upscale it to
• Multiple AI models: Choose a suitable model based on the type and quality of your footage.

How to Fix an Underexposed Video with HitPaw VikPea

Step 1. Upload your video

Launch HitPaw VikPea and go to the AI Color module. Import the underexposed video into the workspace.

Step 2. Choose an AI model

Select an appropriate AI enhancement model based on your footage. For dark footage, choose Low-Light Enhancement Model (or Color Enhancement Model) from the right-hand panel.

Step 3. Preview the enhancement

Preview the processed result and compare it with the original. Check whether faces, subjects, shadows, and other important details are clearer.

Step 4. Adjust and export

Once you are satisfied with the result, choose 4K quality in the Export settings panel and click Export button to export the enhanced video.

Part 4. Practical Tips to Prevent Underexposure When Shooting

• Check the Histogram and Waveform: Monitor your camera display while recording to ensure the exposure curve sits balanced in the middle rather than squashed against the left boundary.
• Use a Wider Aperture: Choose lenses with wider maximum apertures (e.g., f/1.4, f/1.8, or f/2.8) to allow more physical light to reach the sensor.
• Lower Your Shutter Speed: Match your shutter speed to double your frame rate (e.g., 1/50s for 24fps) to maximize exposure time per frame without introducing unusual motion blur.
• Add Auxiliary Lighting: Use portable LED panels, ring lights, or reflectors when shooting subjects indoors or at night.

Conclusion

Underexposed video footage doesn't have to be a lost cause. Minor exposure issues can easily be corrected in standard editors like Premiere Pro or DaVinci Resolve by carefully adjusting shadows and noise reduction. For severely dark clips where manual edits introduce heavy grain and detail loss, leveraging HitPaw VikPea offers an automated, 1-click AI solution to restore brightness, remove noise, and bring hidden details back to life.
