improve details of a video in Amped Replay

Dear loyal readers, welcome to this week’s “How Do I Do This?” blog post! When dealing with CCTV recordings, one rather common issue is that everything looks “slightly blurred”. It could be because of poor camera lenses, poor focusing, or it could even be a compression artifact. The only sure thing we know is how annoying this is. Keep reading to find out how Amped Replay can help you to improve the details of a video!

In Amped Replay, go to the Enhance tab and activate the Sharpen filter. Drag the slider to adjust the strenght of the filter. Done!

Let’s jump to the facts with an example. We’re given this recording of a car, and we’re interested in the license plate. As you can see, the image is a bit blurred, kind of “foggy”, and also dark.

Screenshot of the Enhance tab in Amped Replay software displaying a surveillance video frame of a silver hatchback car on a sunlit road. The vehicle's license plate is partially visible, and shadow covers part of the ground. The interface shows the frame number, timestamp, zoom level (300%), and video size (960x576). Enhancement tools such as "Correct," "Aspect Ratio," "Rotate," "Crop," "Light," "Sharpen," and "Resize" are listed on the right panel. Playback controls and file details are visible along the bottom of the screen.

As to the darkness, we’ve learned just one week ago how to improve contrast and brightness with Amped Replay, which basically boils down to activating the Light filter and configuring it. Here’s the result in our example.

Screenshot of the Enhance tab in Amped Replay software showing a surveillance video frame of a dark gray car on a beige road surface. The vehicle’s license plate is faintly visible, and contrast and brightness adjustments are applied with Manual settings (+86 contrast, +83 brightness) shown in the right-side panel. The interface displays frame 391 of 733, timestamp 00:00:15.620, and a zoom level of 300% with a resolution of 960x576.

Using the Sharpen Filter to Improve Video Details

Much better, indeed! But the slight blur, as expected, is still there. Here comes into play the Sharpen filter. Sharpening means making transitions (edges and variations in general) more pronounced. It helps to make things “stand out” from the surrounding pixel context. Let’s activate the filter and see how it behaves with the default settings, using an image comparison view:

Nice improvement, isn’t it? You can of course play around with the Strength slider and find the best balance. In this specific case, even moving the strength to the maximum value retains good results.

The sharpening filter sometimes causes an increase in the brightness, so we decided to lower a bit the Brightness slider in the preceding Light filter, to avoid pixel saturation (that is, pixels turning totally white). Remember you can use the mouse wheel to edit a slider’s value, so you can keep your eyes on the image and constantly monitor the result.

Screenshot of the Enhance tab in Amped Replay software displaying a video frame of a dark-colored car driving on a light tan road surface. The rear of the car, including the license plate, is visible but partially blurred. Enhancement settings on the right panel show Manual adjustments with contrast set to +86, brightness to +79, and sharpening at maximum strength (+100). Playback controls and video metadata - such as frame 391 of 733, timestamp 00:00:15.620, zoom 300%, and resolution 960x576 - are visible along the bottom.

Just one recommendation: the Sharpen filter should be used prudently when dealing with faces. Indeed, the sharpening process could make some details such as the nose look exaggerated compared to their real appearance, as exemplified below.

Conclusion

That’s all for today! We hope this issue of the “Amped Replay Tutorials: How do I do this?” series was helpful.
