Transitions

How Preview and Program work, and every way to take a source live in Studio: Cut, Quick Play, numbered transitions, the T-bar, stingers, overlays and Fade to Black.

Preview and Program

Studio always has two pictures that matter.

  • Program is what the audience sees. It is what goes to the room, NDI, recordings, streams and the virtual camera. Its tally is red.
  • Preview is what you have staged next. Only you see it. Its tally is green.

You choose Preview, then take it. A take puts the Preview source on Program, and the old Program source becomes the new Preview, so you can take straight back.

Ways to choose Preview: click an input's picture, press its number key, or use Preview in its menu. To skip Preview entirely, press Shift with the input's number to send it straight to Program as a cut (Preview stays as it was), or use the Cut key on its tile. Every take swaps the buses, as on ATEM and vMix: Preview goes to Program and the old Program lands on Preview. A take with nothing on Preview takes Program out to black and puts it on Preview, so the next take brings it back. Each screen's Take works the same on its own Preview and Program.

The switcher column

The Switcher panel, top to bottom: Quick Play, Cut, TRANSITIONS with five numbered buttons, FTB, STINGERS with eight keys, and the clocks. The T-bar runs full height beside them.

ControlWhat it does
Quick PlayTakes Preview to Program with the Quick Play transition. The key shows its effect and time, for example "Morph 0.5s" (on Windows in the full-size column; the tooltip says it too). On Windows it is the green key of the column, with a chevron that edits its transition.
CutTakes Preview to Program at once
Numbered transition buttonsEach button has its own effect and duration and shows them, for example "Fade 0.5s". The time is hidden for Cut
FTBFade to black (see below)
T-barA manual fader for a take
Both apps have five numbered transition buttons, and each can be set to any effect. A new show starts with Quick Play set to Morph (0.5 s) and the buttons set to Fade 0.5 s, Morph 0.5 s, Wipe 0.8 s, Slide 1.0 s and Zoom 0.8 s. Every transition eases in and out by default: a button whose curve you never changed uses Ease In Out (Ease in and out on Windows), not a straight line.

Edit a transition

Open the editor for any numbered button or for Quick Play, and change its effect, direction, duration and curve.

Right-click the key, or click the small chevron on it (tooltip "Transition n settings: effect, direction, duration, curve"). A popover opens with the same form as the inspector, and an Assign Shortcut, MIDI or OSC... link at the bottom.

SettingOptions
EffectCut, Fade, Morph, Wipe, Slide, Zoom, Alpha Fade
DirectionLeft, Right, Up, Down. Wipe and Slide only
DurationA slider from 0 to 5000 ms in steps of 50. Its number follows the drag, and you can drag the number or click it to type a value. Disabled for Cut
CurveLinear, Ease In, Ease Out, Ease In Out, Smooth. Custom appears only when a show you opened carries one. Starts as Ease In Out. Disabled for Cut
T-bar follows the curveOne setting for all buttons: the manual T-bar runs through the curve of the first numbered transition

Morph moves the layers that two scenes share from where they are to where they will be. With nothing shared it fades. It works the same on a screen's Take. See Scenes and looks.

Alpha Fade

Alpha Fade is a crossfade that follows each picture's transparency. On Program every pixel goes straight from the outgoing picture to the incoming one, both over black. Where the incoming source is transparent, the outgoing picture fades out instead of staying until the end and cutting. It suits keyed or transparent sources, such as a chroma-keyed camera or a title with a see-through background. It has a duration and a curve, and no direction. On an overlay channel, or when nothing is coming in, it fades like Fade.

It needs Studio Alpha Fade transition in your plan, on Pro and up (see Plans and limits). Setting it on a numbered transition, on Quick Play, on an overlay channel, or taking with it once all ask for it. A transition you already set keeps running if the plan later drops it, and switching to another effect never asks.

Without the feature the Effect list shows "Alpha Fade, needs upgrade" with a lock, and choosing it is refused.

The T-bar

The T-bar mixes Preview into Program by hand, using the effect of the first numbered transition. Drag it from the top to the bottom to move the picture across; the part you have travelled is lit red. Take it all the way to the end to complete the take, release it at the start to cancel, or leave it in between to hold the mix. It also moves by itself while a take runs, and rests at the top when idle.

Tooltip: "T-bar: drag to mix Preview into Program. Right-click for its curve." Grabbing the cap never makes it jump. Right-click the T-bar for: Curved T-bar (a tick toggle), Assign Shortcut, MIDI or OSC..., Cut and Quick Play. The T-bar is dimmed and ignores drags while switching is locked.

Quick Play

Quick Play is the one-key take: Preview to Program with the transition set on the Quick Play key. It is the default action of every tile's GO key (see Inputs), and it is what Quick Play in an input's menu does after putting that input on Preview.

Fade to Black (FTB)

FTB fades Program to black and back. It is a toggle: lit while Program is black. Windows labels the Program title bar FTB and "Fade to black" while it is on. On macOS you can also switch it from the Program monitor menu (Fade to Black). On Windows the FTB key lights red while it is on.

Stingers

Stingers are video clips that play over a take. Studio has eight stinger keys.

  • Click an unset key (tooltip "Stinger n: not set. Click to choose a media input.") and pick from Set Stinger n from the media or list inputs. With none, the menu says "Add a video or image sequence input first".
  • Or open a media input's inspector and use Use as Stinger > Stinger 1 to Stinger 8. Clear Stinger n removes it.
  • The cut point is half way through the clip and the duration is the clip's length.
  • A set key is lit red while it plays (tooltip "Transition with stinger n"). Right-click it for Clear Stinger n.

Press any stinger key while a stinger is playing to stop it. If its cut point has not come yet, the cut happens at once. A stinger leaves Program whenever it stops playing, so it cannot get stuck on screen.

Overlays

An overlay puts an input on top of Program, for example a lower picture-in-picture. There are eight overlay channels. An overlay channel has its own transition, so it fades or slides in when toggled.

Ways to toggle an overlaymacOSWindows
On a tileNumber keys 1 to 8, as many as the tile has room for, and the Overlays flyout with all eight and On PreviewNumber keys 1 to 8, as many as the tile has room for, and the Overlays flyout with all eight and On Preview
In a menuTile menu Overlay, or Studio > Overlay > Toggle Overlay n (acts on the selected input)Input menu Overlay. Overlay on Preview puts it on that channel's Preview
KeysOption+1 to Option+8 (default)Alt+1 to Alt+8

An overlay on a channel's Preview is staged, not on air.

Channel settings: Program monitor menu Overlay Channels..., the Overlays key in the bottom bar, or the toolbar Inspector. The panel has Channel (Overlay 1 to Overlay 8), On air (what is on the channel, or "Off"), Turn Off, a Transition section (Effect, Duration 0 to 5000 ms), and Auto close: never or Auto close: n s (0 to 600 s) to take the overlay down by itself. Overlay transitions have no direction or curve.

Overlays are a plan feature on some plans. See Plans and limits.

PlayList

The PlayList key in the bottom bar runs a timed sequence of your inputs. Click the cog (Play list items) to edit it in the inspector: each row has an input and a time in seconds (0 to 600; 0 waits for the clip to end, or for Next), and Add Item adds one (5 seconds, Quick Play transition). Use Previous, Start / Stop and Next. The key lights red while running. With no items the key opens the editor.

Lock switching

Lock freezes every control that changes what is on air. See Inputs.

Keyboard keys

Keys work when the Studio window is focused. Single-letter and number keys pause while you type in a text box.

Studio keys come from your External Control configuration, so you can rebind them (see External Control). The shipped Default configuration:

KeyAction
1 to 9, 0Put input 1 to 10 on Preview
Shift+1 to Shift+0Input 1 to 10 straight to Program
SpaceQuick Play
ReturnCut
Command+1 to Command+5Take numbered transition 1 to 5
Option+1 to Option+8Toggle overlay 1 to 8 for the selected input
BFade to Black
MAudio on or off for the selected input
Command+RRecord
Command+Shift+LStream

These stay fixed: Option+Command+0 (Open Studio), Option+Command+M (Audio Mixer), Shift+Command+K (Lock Switching), Command+F (search inputs), Command+Z and Shift+Command+Z (undo and redo scene edits while Studio or a Scene Editor is the front window). The Studio menu lists the current keys beside each action. Right-click a switcher control and choose Assign Shortcut, MIDI or OSC... to bind your own.

Clocks

Under the stingers is a large red clock: recording time while recording, otherwise the event clock, or --:--:-- when neither runs. Below it is the wall clock in HH:mm:ss.
