Sequencer

Last updated 7 August 2026

A sequencer allows to place media in channels along a timeline. A sequencer has one or multiple channels.

All channels within a sequencer play in perfect sync, so put only media that can stay in sync into one sequencer. External sources such as capture inputs that do not run in sync with each other belong in separate sequencers.

Sequencers are created and selected in the list on the left; selecting one shows its properties on the right.

Properties

Setting	Description
Name	Name of the sequencer
Layer	Which sequencer is drawn on top when several play at once. The lowest layer renders first and the highest last. Sequencers sharing a layer render in reverse start order, so the most recently started one renders first
Blend Mode	Blend mode for this sequencer's video channels. The available modes depend on the GPU's support for VkBlendOp
Keying	None, or Color Keying to make one colour transparent. With Smooth Opacity set and Tolerance above 1, transparency fades out across colours within the wider tolerance
Volume	Volume for all audio channels in the sequencer
Opacity	Opacity for all video channels in the sequencer
Tempo*	Playback speed. The asterisk marks it as temporary — the value is not saved with the project
Autostart	Starts the sequencer after the project loads
Loop	Repeats the sequencer
Force start time	Starts from a fixed time inside the sequencer rather than from where the locator sits

Channels

A sequencer holds one or more channels:

Video Channel

Audio Channel

Playback states

States change from the play, pause and stop icons, from the keys below, or from logic in the Node Editor Window.

State	Behaviour
Stopped	Not rendered. Entering this state moves the locator back to 0
Playing	Rendered, with video and audio channels playing
Paused	Video channels freeze on the frame where the pause happened; audio is muted

Keyboard

The transport uses the JKL shuttle convention.

Key	Does
`Space`	Play / pause. Leaves shuttle mode first, so playback resumes at the sequencer's own tempo
`J`	Shuttle backwards. Tapping again ramps through 1×, 2×, 4×, 8×
`K`	Pause and leave shuttle mode, restoring the original tempo. The locator stays where it is
`L`	Shuttle forwards, ramping the same way
`Home` / `End`	Move the locator to the start or end of the range
`Delete`	Delete the selected event
`Ctrl`+`C`	Copy the selection
Double-click	Create an event on a channel

Shuttle is a non-destructive override: entering it snapshots the sequencer's tempo, and K, Space or stopping restores it. A sequencer left shuttling at −4× therefore still plays forward at its configured speed next time.

Common Mistakes

Sources drift apart within one sequencer — everything in a sequencer is held in sync, which only works for media that can be. Put free-running capture inputs in their own sequencer.
A speed change disappears after reload — Tempo* is deliberately not saved. For a permanent change, set the speed on the channel or the event.
The wrong sequencer is on top — with equal layers the order comes from when each was started, not from the list. Give them distinct layers when it matters.
Stopping loses the position — stop resets the locator to 0. Use pause, or K, to hold the position.
