Enhancing clips

VideoStudio lets you improve the quality of a video or image clip by adjusting its current properties such as its color settings in Color Correction.

Adjusting color and brightness

Adjust color and brightness settings of images and video on the Timeline by clicking Color Correction in the Options Panel.

To adjust color and brightness:

1 Select the video or image clip to enhance on the Timeline.

2 Drag the sliders to the right to intensify the Hue, Saturation, Brightness, Contrast or Gamma of the clip.

3 Watch the Preview Window to see how the new settings are affecting the image.

Note: Click Reset to restore the original color settings of the clip.

Adjusting white balance

White balance restores the natural color temperature of an image by removing wrong color casts due to conflicting light source and incorrect camera settings.

For example, an object illuminated with incandescent lights may turn out too reddish or yellowish in an image or video clip. To successfully achieve its natural effect, you need to identify a reference point in your image which represents the color white. VideoStudio gives you different options in selecting the white point:

  • Auto: Gives you automatic calculation of the fitted white point that is well-matched with the overall color of your image.

  • Pick Color: Allows you to manually select the white point in the image. Use the Eyedropper Tool to pick a reference area that should be white or neutral gray.

  • White balance presets: Automatically selects white point by matching specific light conditions or scenarios.

  • Temperature: Allows you to specify color temperature of light sources in Kelvin (K). Lower values indicate Tungsten, Fluorescent and Daylight scenarios while Cloudy, Shade and Overcast fall under high color temperature.

To adjust White balance:

1 Select an image or video clip on the Timeline or the Library.

2 In the Edit Step Options Panel, click Color Correction.

3 Select White balance.

4 Determine how you want to identify the white point. Choose among the different options
(Auto, Pick color, White balance presets or Temperature).

7 Click to identify a reference point in your image which represents the color white.

8 Watch the Preview Window to see how the new settings are affecting the image.

Tip: Click the White balance drop-down arrow to display more color adjustments you can use. Select Vivid Color or Normal Color for the color intensity. The Weaker, Normal and Stronger options specify the level of sensitivity of White balance.

Adjusting tones

To adjust the tone quality of your video or image clips, click Color Correction in the Edit Step Options Panel and select Auto Tone Adjustment. You can indicate if you want the clip as Brightest, Brighter, Normal, Darker or Darkest by clicking the Auto Tone Adjustment drop-down menu.

Applying video filters

Video filters are effects that you can apply to clips in order to change their style or appearance. For example, you can improve the color balance of a clip, or make it look like a painting.

Video filter samples:

  • DeBlock: Smoothens uneven areas in a clip and reduces noise like block artifacts or mosquito effect that are usually found in some highly compressed videos.

  • DeSnow: Removes visible and dynamic “snowy” noise patterns in videos captured from sources with poor TV signals or video clips usually taken under low lighting conditions or by cameras with high ISO values.

  • Anti-shake: Allows you to correct or stabilize sub-standard videos due to camera shake.

To apply a video filter to a clip (video or image) in the Video Track:

1 Select a clip on the Timeline.

2 Click the Attribute tab in the Edit Step Options Panel.

3 Choose a video filter from the Video Filter folder in the Library to apply to your clip (by clicking the thumbnail).

4 Drag and drop the video filter onto your clip in the Video Track.

Note: By default, the filter applied to a clip is always replaced with the new filter dragged onto the clip. Clear Replace last filter to apply multiple filters to a single clip. VideoStudio allows you to apply a maximum of five filters to a single clip. You can also choose the filter to be previewed through the selection in the view toggle. In the event that you choose to render your project, only enabled filters will be included in your movie.

5 Click Customize Filter in the Options Panel to customize the attributes of the video filter. Available options depend on the selected filter.

6 Preview how your clip looks with the video filter applied to it using the Navigator.

Note: When there is more than one video filter applied to a clip, you can change the order of filters by clicking Corel Videostudio edit filter up Enhancing clips or Corel Videostudio edit filter down Enhancing clips. Changing the order of the video filters will have drastic effects on your clip.

Key frame settings

VideoStudio allows you to customize video filters in a variety of ways. One way is by adding key frames to your clips. Key frames are frames in a clip where you can specify a different attribute or behavior for your video filter. This gives you the flexibility to determine how your video filter will look like at any point in a clip.

To set key frames for your clips:

1 Drag and drop a video filter from the Library onto a clip on the Timeline.

2 Click Customize Filter. The dialog box for the video filter opens.

Note: Settings available in the dialog box are different for each video filter.

3 In the Key frame controls, drag the Jog Slider or use the arrows to go to the frame where you’d like to change the attributes of your video filter.
