End Card

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.

end-card.sh <in.mp4> <out.mp4> [dur=2.5] [line1="FOLLOW FOR MORE"] [line2="@C0BALT_CUT"]

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).
