| description | Composite a closing CTA banner ("FOLLOW FOR MORE" + @C0BALT_CUT) over the last ~2.5s of a finished short so it lands on an intentional beat instead of dead-stopping on a dangling word. Timeline-preserving (audio copied, duration identical), deterministic, non-fatal. END_CARD=0 skips. |
end-card
Closing-beat overlay. Runs in the finishing phase AFTER bg-music and BEFORE
qc-clip, the last visual touch before the short is saved. Addresses the
"ends abruptly / no loop or CTA" retention leak: the few viewers who reach the
end get a branded call-to-action instead of a hard stop on a half-finished
word.

- Timeline-preserving. The card is an overlay that fades in over the final
dur seconds of the existing footage. Audio is stream-copied; total duration
is unchanged, so no downstream timestamp moves.
- Brand. Impact, Platinum
#E8ECF1 headline + Sapphire Glow #2E6BFF
handle, thick black stroke — rendered by render_endcard.py to a transparent
PNG (the stack has no drawtext/libass), composited by ffmpeg.
- Placement. Centered horizontally; vertical center at
END_CARD_Y_FRAC
(default 0.60) so it sits above the lower-third caption band.
- Idempotent via
.ecmeta signature. Non-fatal: any probe/render/encode
failure falls back to a stream-copy passthrough. END_CARD=0 disables.
Knobs: END_CARD (0 disables), END_CARD_DUR (default 2.5), END_CARD_TEXT,
END_CARD_HANDLE, END_CARD_Y_FRAC (default 0.60).
