Marks and markers

As your edit grows, you’ll want ways to point at specific moments — “start the export here,” “this is where the music drops,” “come back and fix this cut.” Sprocket gives you two tools for that: in and out marks define a range of the timeline to work on, and markers drop labelled pins at single moments you want to find again.

Both live on the timeline ruler and work no matter which editing tool is active.

What’s in this guide

Section titled “What’s in this guide”

In and out marks

Section titled “In and out marks”

An in point and an out point define a range of your sequence — the part you want to play, render, or export. You set them at the playhead:

  • I — set the in point at the playhead
  • O — set the out point at the playhead

The marked range appears as a shaded band across the ruler, with a brighter edge at each end:

The timeline ruler with an in/out range: accent-coloured edges at the 00 in point and 00 out point, and the range between them shaded

To clear a mark, hold Alt:

  • Alt+I — clear the in point
  • Alt+O — clear the out point

You don’t have to set them in order. If you set an in point later than the current out point (or an out point earlier than the in point), Sprocket clears the conflicting mark so the range always makes sense.

Marks belong to the sequence you’re working in. If you switch to another sequence and come back, each sequence keeps its own in and out points.

Tip: In and out marks are what the Export dialog’s In/Out range option and the Sequence ▸ Render In to Out command act on. Set them once and every “just this part” action uses the same range.

Play just the marked range

Section titled “Play just the marked range”

Once you’ve set an in and an out point, choose Sequence ▸ Play In to Out (Ctrl+Shift+Space) to preview only that stretch. Playback starts at the in point, stops at the out point, and loops back to the in point so you can watch the same section over and over while you fine-tune it.

If only one mark is set, playback fills in the missing end — a range with just an in point plays to the end of the sequence, for example. With no marks at all, it simply plays the whole sequence.

Plain playback with Space ignores the marks entirely, so you always have one key for “play everything” and one for “play just this bit.”

Markers

Section titled “Markers”

A marker is a coloured pin on the ruler that flags a single moment — a good spot for a cut, a lyric to land a title on, a note to revisit. Unlike in/out marks (of which there’s one pair), you can drop as many markers as you like.

  • M — add a marker at the playhead
  • Shift+M — jump to the next marker
  • Ctrl+Shift+M — jump to the previous marker

New markers are added at the playhead with a default colour. Adding one and then jumping between them is the fastest way to lay down a rhythm of edit points and then move between them without hunting along the timeline.

The Markers panel

Section titled “The Markers panel”

To see all your markers in one list, click Markers at the top-right of the Timeline pane. A small panel opens showing every marker in order:

The Markers panel: a "+ Add at playhead" button and three markers, each with a coloured dot, a time-and-name label such as "0.01 · Marker 1", and an ✕ remove button

From here you can:

  • Add a marker at the playhead with + Add at playhead — the same as pressing M.
  • Jump to a marker by clicking its label. The playhead moves to that marker’s time.
  • Remove a marker with the ✕ button on its row.

Each row shows the marker’s time and name — for example 0:04.20 · Marker 2. Markers you haven’t named show as Marker 1, Marker 2, and so on.

Tip: When the panel is empty it reminds you how to start: press M with the playhead where you want the first marker.
