Remarks

The fade-in effect creates a smooth transition where the video content gradually becomes visible, starting from complete black (or transparency) and progressing to full opacity. The transition occurs over the time period defined by VisioForge.Core.Types.VideoEffects.VideoEffect.StartTime and VisioForge.Core.Types.VideoEffects.VideoEffect.StopTime.

Common applications:

• Video opening sequences
• Scene transitions from black
• Revealing content gradually
• Professional video intros
• Soft entry into new scenes or chapters

The fade-in effect is typically applied at the beginning of a video or scene. The duration of the fade is controlled by the difference between StartTime and StopTime.

For opposite effect (fading to black), use VisioForge.Core.Types.VideoEffects.VideoEffectFadeOut. For more control over darkness/brightness fading, use VisioForge.Core.Types.VideoEffects.VideoEffectDarkness with ValueStop.

Constructors

VideoEffectFadeIn(bool, string, TimeSpan, TimeSpan)

Initializes a new instance of the VisioForge.Core.Types.VideoEffects.VideoEffectFadeIn class with specified parameters.

public VideoEffectFadeIn(bool enabled, string name = "FadeIn", TimeSpan startTime = default, TimeSpan stopTime = default)

Parameters

enabled bool

true to enable the effect immediately; false to create the effect in a disabled state.

name string

An optional name identifier for this effect instance. Default is "FadeIn".

startTime TimeSpan

The time at which the fade-in should begin. Typically set to the start of a video or scene. Default is Zero (from beginning).

stopTime TimeSpan

The time at which the fade-in should complete (full visibility reached). Required to define fade duration. The fade duration is (stopTime - startTime).

Remarks

The fade-in effect requires both startTime and stopTime to be properly set to define the fade duration. Setting both to zero will result in no visible effect.

Typical fade durations range from 1-3 seconds for subtle transitions, up to 5+ seconds for more dramatic reveals.

Methods

GetEffectType()

Gets the specific type of this video effect.

public VideoEffectType GetEffectType()

Returns

VideoEffectType

Returns VisioForge.Core.Types.VideoEffects.VideoEffectType.FadeIn to identify this as a fade-in transition effect.

Remarks

This method is used by the video processing pipeline to route the effect to the appropriate fade transition processor.
