Visual Effects

Visual effects can be assigned to any page element using a CSS selector, both to the entire page and to a video element.

Filters

  1. Brightness amplitude, including RGB components.
  2. Brightness exponent, including RGB components.
  3. Contrast, including RGB components.
  4. Saturation, including RGB components.
  5. 3D anaglyph with presets: red-cyan, cyan-red, green-magenta, magenta-green, red-blue, blue-red.
  6. Color shifting using various methods, including shifting all colors together and individually.
  7. Sharpening, including scale parameters, the number of pixels in the matrix, the visibility of the sharpening layer, the brightness amplitude, and the brightness exponent of this layer. Sharpening can also be blurred by using negative scale values.
  8. An additional sharpening option, as in the previous section, can be applied again by adjusting its parameters.
  9. Color inversion, including RGB components.
  10. Blur.
  11. Grayscale.
  12. Sepia.
  13. Opacity.

Audio Effects

Equalizer. An equalizer is useful if you want to enhance audio data or compensate for the characteristics of your audio output equipment. It's also used for music.

Filters

  1. HP (high-pass filter).
  2. HS (high-shelf filter).
  3. LP (low-pass filter).
  4. LS (low-shelf filter).
  5. Peaking filter.
  6. Notch filter.
  7. BP (constant skirt).
  8. BP (zero peak).

Audio normalization

Audio normalization is useful when the video involves a loud or quiet speaker. Audio normalization eliminates the need to increase or decrease the volume for different videos, as this extension automatically adjusts the audio volume. In some cases, you may hear new sounds that weren't audible before normalization.

Interactive elements in text

  1. Links
  2. Timecodes for video or audio

Radars

Radars are a feature that allows you to link context (effects and notes) to a page. Radars allow you to specify rules using a variety of page information.

Available information for linking to a page:

  1. Page title.
  2. Page address.
  3. JSON-JD elements.
  4. Microdata elements.
  5. Elements from the HTML meta tag.

How to Fix Fake 4K Quality on YouTube

On YouTube, bloggers upload videos that look low-quality, specifically blurry. This is often surprising, and it's unclear how 4K quality can be so blurry. Typically, such quality should demonstrate a lot of detail, like skin texture. YouTube values high-resolution videos, so many bloggers have an incentive to make them high-quality. It might seem like bloggers are deceiving YouTube by passing off low quality as high quality, but often that's not the case. They apply blurring and adjust the contrast. They distort skin color as if there's paint on it.

Blurring

This effect is good due to its simplicity. It's too primitive to cause many problems during setup. But its primitiveness plays into the hands of those who want to reverse it. When blurring is used, it's often just a slight distortion that can be partially reversed. In fact, a lot of texture information remains, but it's simply hard to see. You can use your own filter to improve video quality.

For example, you can use sharpening to partially correct the blur.

Using the Page Context extension, you can add sharpening to a page element to make details visible. Sharpening has a simple formula, but it still has parameters, so you might not have enough sharpness with one set of parameters. The extension can apply sharpening for two sets of parameters simultaneously.

I recommend using one set for Distance 1, and a second set of parameters for Distance 4. You will see that the effects from these sets are different. The greater the difference in Distance between the sets, the less similarity in the effects. Each of these effects can, in its own way, remove blurring.

Low Contrast

It's a bit more complicated here. Contrast can also be partially restored, but when restoring contrast, you might sacrifice brightness, making the entire image darker. You can also degrade the image by creating out-of-range brightness values. Contrast restoration works well on videos if the changes in contrast and lighting are not significant, because after significant changes, new settings need to be created. But this isn't always a problem either, since bloggers might have favorite filter settings for reducing contrast, and they may not change the lighting.

To restore contrast, you can use the following tools in the Page Context extension:

  • Brightness amplitude
  • Brightness exponent
  • Contrast
  • Saturate

Usually, for this, you need to increase Brightness amplitude and Brightness exponent, and decrease Contrast and Saturate.

The result on many videos will be such that you will see the familiar 4K quality you're used to.

The Page Context extension allows you to bind these settings to page information, which means, for example, for YouTube, you can bind the settings to a channel. To do this, you need to go to the Radar using the back arrow from the effect settings and in its rules, select an element with the key $[*].author.url in the rule template hints.
