# Rendering the Multi-Layer Timeline

Lustre renders out what is displayed in the multi-layer timeline and Player, according to:

- Top vertical priority
- The presence or absence of priority shots and muted layers
- The Solo status

If Solo mode is disabled, Lustre renders the topmost layer by default. If there are gaps, Lustre takes into account top vertical priority behaviour and render out all the shots from the lower layers that are visible through the transparent gaps that are above.

If you do not want a shot in a lower layer to be rendered that is located beneath a gap, you can replace the gap with a virtual black clip. See Adding a Virtual Black Clip using the Storyboard and Adding Black Media to the Timeline.

If you wish to render out the shots on a specific layer, you either must Solo the active layer, or Mute the unwanted layers. If there are gaps in this layer, the gaps are skipped by the rendering process .

If you wish to render out a shot that normally would not be rendered because top vertical priority renders out a shot on a different layer, you can use the shot priority function to prioritize this shot.

Rendering the Multi-Layer Timeline with Normal

When the Normal button is selected, Solo mode is disabled, and there are no muted layers, Lustre interprets gaps as being transparent and flattens layers in a top-down manner. Lustre renders out what is visible in the multi-layer timeline in accordance with top vertical priority. The individually graded shots with frames that are visible are rendered and saved to their own folder in the Renders Home location. If there are no shots beneath the gap, the rendering process skips the gap.

You can render one specified layer at a time by muting unwanted layers or soloing a desired layer. Lustre renders individually graded shots with frames that are visible as individual shots and saves them to their own UID directories in the Renders Home location.

Rendering the Multi-Layer Timeline with No ShotID

Renders the same way as Normal mode. However, when rendering with No ShotID, you can render one layer only for each grade. Consequently, when rendering out L1 first, then rendering out L2 within the same grade, the L2 render overwrites the previous L1 render files.

To render out L2 without overwriting the previous L1 render, you can do one of the following:

- Save a new grade (i.e., grd02).
- Use Normal render mode.
- Add a UID token in the filename. See Render Naming Settings

Rendering the Multi-Layer Timeline with One Sequence

When the One Sequence button is selected, Solo mode is disabled, and there are no muted layers, by default Lustre sees the gaps as transparent and flattens the layers in a top-down manner. Lustre renders out what is visible in the multi-layer timeline in accordance with top vertical priority. Lustre renders the individually graded shots with frames that are visible to the scene folder as a single sequence in the Renders Home location. If there are no shots beneath the gap, the gap is rendered as black to the same single sequence in the same scene folder.

When the One Sequence button is selected, you can render one specified layer at a time by soloing the desired layer or muting the unwanted layers. Lustre renders the individually graded shots with frames that are visible to the scene folder as a single sequence in the Renders Home location. Gaps are rendered as black to the same single sequence in the same scene folder.

NoteWhen rendering with One Sequence, you can render one layer only for each grade. That is, if you render out L1 first, and then within the same grade renders out L2, the L2 render will overwrite the previous L1 render files. To render out L2 without overwriting the previous L1 render, you must save a new grade (grd02).

Rendering the Multi-Layer Timeline with Src Grade

Src Grade works just like Normal render in that it renders each shot to its own folder under the SrcGrade directory and the rendering process will skip gaps if there are no shots beneath them. When this option is enabled, the rendering process bypasses any dissolve transitions and retime parameters. In other words, dissolves become hard cuts and retimes are rendered with a default of 100% value.
