Widgets

Each overlay is a widget with its own tab and its own canvas presence:

Widget What it puts on the frame
Background Image or video behind the main clip
CTA Your call-to-action overlay clip or image
Brainrot The split-screen filler clip, above or below the main clip
Text Styled text burned in, per brand
Watermark Your logo — the brand's logo when the widget has none
Sound A music bed from file or the brand's sound pool
Outro clip The closing clip, set on the Endcard tab

Text widget

Different brands can carry different lines on the same stack. Center the lines in the text block centers each line inside the block; the block keeps its width and position.

Sound: ducking and loudness

Ducking dips the music under speech automatically (strength in percent), driven by the transcript's word timings. Loudness is on by default: the finished mix is brought to −14 LUFS, the level TikTok, Instagram and YouTube play at, so a quiet source clip no longer posts quiet — switch it off to keep the source level.

NOTE

Ducking needs a transcript — it is computed from the word timings. Loudness does not: it measures the finished mix.

Outro clip

The outro lives on the Endcard tab: Outro clip takes a video, or a still image held for Image outro duration (s) — a static end card without video editing. It is always the last thing in the file, after the endcard segment.

TIP

Every widget that takes media also accepts brand pools. Leave the widget's own file empty and the renderer draws from the brand's pool for that asset type, rotating per variant.
