Effects Mode: Crossfade
Smooth transitions between clips in Effects Mode, with a configurable 0.1–5.0 second fade.
Effects Mode: Crossfade
Crossfade brings smooth transitions to Effects Mode. When enabled, triggering a new video no longer cuts instantly — the outgoing and incoming clips blend across a configurable fade, exactly like a video mixer's T-bar. All eight real-time effects (brightness, contrast, hue, saturation, rotation, scale, position X/Y) apply to the combined image during the fade.
Crossfade is part of Effects Mode and is available only when the Video Mode is set to Effects. Fast Trigger and Timecode modes are unaffected.
Where to Find It
Click the gear icon in the top-right corner of any page.
Select System, then open Beta Features.
Expand the Effects Mode (Video Playback) panel.
Scroll to the Crossfade section.
There you'll find:
Enable Crossfade — the master switch for this feature.
Crossfade Duration — how long the fade lasts, in seconds. Range is 0.1 to 5.0 seconds in 0.1 s steps (e.g.
1.2). The default when first enabled is 1.0 second.
Changes apply immediately to the next trigger — no restart required. Turning the toggle off disables crossfading entirely (instant cuts).
Rules During a Fade
New triggers are ignored while a crossfade is in progress. If you fire another note mid-fade, it's ignored. Wait for the fade to finish (plus a fraction of a second), then trigger again. Keep this in mind when choosing longer durations for fast-paced triggering.
Blackout crossfades too. Triggering blackout (Note 0) fades to black over the same duration. Like any other trigger, blackout is ignored if a fade is already running.
Re-triggering the same clip restarts it instantly. Firing the note of the clip that's already playing seeks back to the start with no fade, same as it always has.
Timecode Is Always Instant
Timecode playback is frame-accurate by design, so crossfade is automatically bypassed whenever timecode is active — clip changes driven by LTC are always instant, regardless of the Crossfade setting. You don't need to toggle anything off before a timecode show.
Interaction with Effects
The MIDI CC effects (CC 48–55) and reset notes (110–118) work exactly as before. Effects are applied to the combined output, so during a fade both clips are colored and transformed together — brightness, hue, rotation, scale, and position all remain live throughout the transition.
Good to Know
1080p limit. As with all of Effects Mode, video is limited to 1080p 60fps (4K media is not supported in this mode).
Beta feature. Crossfade ships as part of Effects Mode under Beta Features. Feedback to support@4cast.world is welcome.
