The logo goes on every clip, the outro plays whole, and a guest has a name - #148

Conversation
… name Four things measured against a published short that was cut with this very renderer. None of them needed a new feature; all four were the renderer not doing what it was told. `--logo` was accepted, resolved from the asset store, and then dropped unless the caption style happened to be "branded". Two gates did it: a `logo_support` flag in the style config, and the fact that the logo was drawn inside the branded caption component. A logo belongs to the show, not to a caption style. Both gates are gone, the mark moved one level up into CaptionedClip at exactly its old position, and a branded render is byte-identical, frame hash for frame hash. Subtle captions faded in and then cut, so every chunk boundary flickered: the outgoing line vanished on the frame the incoming one started at zero. They now ramp down inside their own window, which crossfades without moving a single caption timing. Skipped on chunks too short to hold full opacity. An intro or an outro was joined with 0.8 seconds of crossfade through black, which ate three quarters of a second of both. Six seconds of clip plus two of outro came out at 7.23. A designed bookend should be cut to; the fade is now a number, and it defaults to none. And a clip lifted out of an hour of conversation opens on a stranger, so there is a lower third: name, role, an accent underline, gone after three seconds. `--name-card`, `--name-card-sub`. Two regression tests, because this class of bug is silent: one asserts no caption style may gate the logo, the other that the name card reaches the renderer at all. The suite already caught one live mistake here — a parameter used in a body whose signature never got it, swallowed by the surrounding except.

review edits.
- Around line 585-586: Update the --bookend-fade argument definition to use

configuration update so preset bookend_fade values are overridden only when the
CLI option is explicitly supplied.

- Around line 923-924: Update the ASS fallback path around the clip-generation
logic at lines 934-958 so a supplied name_card is rendered as an equivalent
lower-third overlay. Ensure this applies when use_ass_captions is enabled and
when Remotion falls back to ASS, including --fast; if ASS cannot support
name_card, reject the option combination before generating a clip rather than
silently omitting it.
In `@remotion/src/components/NameCard.tsx`:
- Around line 41-44: Update the rendering logic in NameCard around fadeInOut so
frames at or beyond seconds * fps return null, ensuring the card unmounts at its
configured duration. Also validate or clamp seconds so durations shorter than
the fade ramps cannot produce unsupported fade behavior.

The logo collided: this branch hoists it out of BrandedCaptions into a top-level Watermark so all four caption styles carry it, while #139 kept it inside BrandedCaptions and taught it --logo-position. Taking either side whole loses something, so the hoist stays and the position expression moves into Watermark with it. BrandedCaptions keeps logoSrc and logoPosition even though it no longer draws the logo: its caption margin still has to leave room for one. The box constants move to Watermark and are imported back, so the mark and the gap reserved for it cannot drift apart. Known gap, opt-in only: that margin guard exists only in BrandedCaptions, so --logo-position bottom-* can overlap captions on hormozi, karaoke and subtle. The default is top-left. Also closes the four review findings: - --bookend-fade defaulted to 0.0, so it overwrote a preset's value on every run. It defaults to None now and only an explicit flag wins. - The interactive re-render dropped name_card and bookend_fade, so a reviewed clip came back without its lower third. - A name card reached only Remotion. On --fast or an ASS fallback the clip rendered without it. That combination is refused now. - The name card outlived its own duration whenever the fade ramps did not fit inside it.

… symlink The guard sat inside the "there are words to caption" branch, so an uncaptioned render (a party or action profile skips transcription) took --name-card and produced no lower third. It runs before the branch now and names which of the two reasons applies. .gitignore lists node_modules/ with a trailing slash, which does not match a symlink of that name, so one used to link a node_modules for the test run was committed with an absolute path under a home directory.

Four fixes, all measured against a published Deeptech Decoded short that was cut with this renderer. None needed a new feature; each was the renderer not doing what it was told.
--logowas dropped on three of four caption stylesTwo gates: a
logo_supportflag in the style config that onlybrandedset true, and the logo being drawn inside the branded caption component. So the flag was accepted, the asset resolved, and the watermark silently never drawn onhormozi,karaokeorsubtle.A logo belongs to the show, not to a caption style. Both gates are gone and the mark moved one level up into
CaptionedClip, at exactly its old position and size.A branded render is byte-identical — same frame hash before and after (
