Jianying Text Style Reference

Jianying Text Style Reference

Treat a Jianying word-art card as four separate evidence layers:

catalog card -> ressdk http_cache metadata -> artistEffect package
             -> rendered glyph behavior

Use jianying-reference for text animations such as typewriter, entry, exit, loop, or per-character motion. Use this skill for the static visual appearance of editable text.

Follow jianying-draft-binary-reference for private ABI ownership evidence and jianying-transition-reference for the local-only runtime lifecycle. Reuse the verified private backup instead of creating another binary collection.

Read package-formats.md before interpreting an effectStyle.json, shader package, or QCut implementation gap.

Keep Evidence Private

• Work read-only against locally cached files from the signed-in Jianying client.
• Use a disposable draft and change exactly one card during a cache probe.
• Keep database extracts, signed URLs, packages, textures, fonts, shaders, prefab data, and captures in a scratch directory outside the repository.
• Never commit or redistribute Jianying assets. A free or VIP flag is product access state, not a redistribution license.
• Record behavior, normalized parameters, equations, and original QCut code. Use synthetic fixtures and QCut-owned or separately licensed visual assets.

Locate the Catalog Record

Find every local resource database; do not assume one account directory:

CACHE_ROOT="$HOME/Movies/JianyingPro/User Data/Cache"
find "$CACHE_ROOT/ressdk_db" -name rp.db -type f -print

Query http_cache, including recent rows that may not be materialized in the effect table:

DB="/absolute/path/to/ressdk_db/<account-id>/rp.db"
sqlite3 -readonly -json "$DB" '
  SELECT id, url, timestamp
  FROM http_cache
  WHERE url LIKE "%flower%" OR url LIKE "%get_panel_info%"
  ORDER BY timestamp DESC;
'

Keep 64-bit IDs as strings. Extract one response to scratch without printing signed item_urls:

SCRATCH="$(mktemp -d /tmp/jy-text-style.XXXXXX)"
ROW_ID="<http-cache-row-id>"
sqlite3 -readonly "$DB" \
  "SELECT response_body FROM http_cache WHERE id=$ROW_ID" \
  > "$SCRATCH/catalog.json"

jq '[.data.effect_item_list[]? | {
  id: .common_attr.id,
  title: .common_attr.title,
  md5: .common_attr.md5,
  category_ids: .common_attr.category_ids
}]' "$SCRATCH/catalog.json"

For panel responses, inspect .data.categories and .data.category_resources. For category responses, inspect .data.effect_item_list[].common_attr. Copy rp.db-wal and rp.db-shm with a copied live database, or query the original database read-only.

Map One Card to Its Package

Prefer the catalog identity tuple resource id + md5:

~/Movies/JianyingPro/User Data/Cache/artistEffect/<resource-id>/<md5>/

Do not default to Cache/effect; verified word-art packages use Cache/artistEffect. If catalog identity is unavailable, create an mtime baseline before touching one uncached card:

MARKER="$SCRATCH/before"
touch "$MARKER"
# In Jianying, preview or apply exactly one uncached card and wait for download.
find "$CACHE_ROOT/artistEffect" -mindepth 2 -maxdepth 2 -type d \
  -newer "$MARKER" -print

An already cached card may leave no new mtime. Treat the card's download-arrow state and an exact catalog path as stronger evidence than a blank diff. Reject the mapping when multiple unrelated packages change.

Use the correct UI action:

• In the left 花字库, select a card to preview it; use the card's bottom-right add control to create a new styled text clip.
• To style an existing clip, select that clip and use the right property panel 文本 -> 花字; selecting a style there must not create another text layer.

Record which action was used. Preview, download, apply-to-existing, and add-new-text are different state changes.

Classify Before Decoding

Inspect the package entry point:

PACKAGE="/absolute/path/to/artistEffect/<resource-id>/<md5>"
jq -r '[.effect.Link[]?.type] | unique | .[]' "$PACKAGE/config.json"
find "$PACKAGE" -maxdepth 2 -type f -print | sort

Route by type:

Do not infer behavior from the package folder name, card title, or cover_icon.png. The cover is a thumbnail, not the style implementation.

Decode TextStyle

Preserve the complete versioned appearance instead of flattening it into one CSS text shadow:

jq '{
  version,
  textable,
  fill,
  strokes,
  inner_shadows,
  shadows
}' "$PACKAGE/effectStyle.json" > "$SCRATCH/style-summary.json"

Classify every layer's content.render_type as solid, gradient, or texture. Preserve array order and all alpha, color, angle, distance, blur, scale, range, wrap, flip, and blend parameters. Resolve texture paths relative to the package only for local analysis.

Render through a glyph alpha or SDF mask. A normal TextStyle does not imply a rectangular background; a visible thumbnail-colored rectangle in QCut usually means the preview image or texture was composited without the glyph mask.

Handle Runtime Text Packages

For InfoSticker, inventory content.json, sticker.config, scene, prefab, material, shader, render-target, texture, and font references. Treat SDFTextSystem and readable shader stages as architectural evidence, not as a portable package. Missing engine fonts or binary prefab parameters mean the package is not self-contained outside Jianying.

Capture the result over high-contrast footage with the same text, font size, canvas, scale, and normalized position. Compare full-canvas frames. Do not claim exact parity from a cropped card thumbnail.

Verify With the Local Runtime Oracle

Use the repository's independently written probe when private runtime evidence is needed. It reuses the durable local-only runtime at:

~/Library/Application Support/QCut/PrivateRuntimes/JianyingTransition/current

Do not make another binary copy when that manifest passes. Never commit the runtime, package, font, generated payload, or rendered frame.

Render one real package with Jianying's host payload and type-3 text segment:

JY_RUNTIME_ROOT="$HOME/Library/Application Support/QCut/PrivateRuntimes/JianyingTransition/current" \
  JY_TEXT_PACKAGE="$CACHE_ROOT/artistEffect/<resource-id>/<md5>" \
  JY_TEXT_OUTPUT="$SCRATCH/frame.rgba" \
  JY_TEXT_PAYLOAD_OUTPUT="$SCRATCH/payload.json" \
  JY_TEXT_FONT_PATH=/absolute/path/to/local-font.ttf \
  JY_TEXT_CONTENT=花字测试 \
  JY_TEXT_FONT_SIZE=18 \
  JY_TEXT_SEGMENT_TYPE=3 \
  JY_VIDEO_WIDTH=512 \
  JY_VIDEO_HEIGHT=512 \
  research/jianying-runtime-probe/run-probe.sh text-frame

The proven sequence is important:

1. Build a TextStickerFilter and apply the effect path through the host API.
2. Serialize the engine-generated text payload.
3. Create the TextSegment using the package directory.
4. Add it to SwingManager, then pass the generated payload through bef_swing_segment_sticker_set_params before seeking a frame.

Directly creating the segment from the generated JSON rendered blank in the verified runtime. Do not replace the sequence with a shorter guessed call path.

ScriptInfoSticker is not a type-3 text effect. Its proven initialization is:

create ScriptSegment(type 10, {"path":"/absolute/package/path"})
  -> add segment to SwingManager
  -> seek without a TextStickerFilter payload

The path key is required. A bare path or a JSON string root resolves to an empty package path and attempts to read /config.json. A valid path object lets the engine validate ScriptInfoSticker, load js/template/template.js, and initialize the package's ScriptTemplate content.

For cache coverage, use the baseline-aware batch:

JY_TEXT_PACKAGE_TYPE=TextStyle \
  JY_TEXT_FONT_PATH=/absolute/path/to/local-font.ttf \
  research/jianying-runtime-probe/run-text-package-batch.sh

JY_TEXT_PACKAGE_TYPE=InfoSticker \
  JY_TEXT_FONT_PATH=/absolute/path/to/local-font.ttf \
  research/jianying-runtime-probe/run-text-package-batch.sh

JY_TEXT_PACKAGE_TYPE=ScriptInfoSticker \
  JY_TEXT_FLOWER_ONLY=0 \
  JY_TEXT_TIMESTAMP=700000 \
  JY_TEXT_FONT_PATH=/absolute/path/to/local-font.ttf \
  research/jianying-runtime-probe/run-text-package-batch.sh

The batch defaults to exact %flower% catalog identities and compares every RGBA frame with a no-effect baseline. A visible frame that matches the baseline is fallback, not success. On 2026-08-11, the current Jianying 11.2.0 cache passed 197/197 TextStyle and 79/79 InfoSticker packages, all with transparent pixels and package-unique hashes. A separate local sample passed 25/25 ScriptInfoSticker packages through type 10, also with transparent pixels and 25 unique hashes. The earlier type-3 run returned one ordinary-text hash for all 25 and is a negative control, not a support verdict. All 25 script packages reproduced identical hashes with the Jianying app Framework path disabled. These are one local cache snapshot's results, not a claim about every Jianying account or release.

To verify editable script text, set JY_TEXT_SCRIPT_TEXT. The default JY_TEXT_SCRIPT_EDIT_MODE=runtime calls bef_swing_segment_set_params after initialization; it changed 22 of the 25 sampled package hashes. Do not treat a zero return code alone as editable success. Compare the edited frame hash with the package's default frame.

Use JY_TEXT_SCRIPT_EDIT_MODE=preload-copy for packages whose script does not finish constructing editable widget references. This mode copies the package under the external evidence root, distributes the replacement across existing rich-text slots, edits only the copied content.json, and creates the type-10 segment from that copy. It never mutates the Jianying cache. The app-less local matrix rendered visible transparent output for 25/25, with all 25 hashes different from their default frames. Keep this as a private-adapter fallback, not as evidence that QCut's portable renderer supports ScriptInfoSticker.

Keep style-package and font-file coverage separate. This matrix varies the flower package while holding one known-good font constant. Use the font lab's own load, glyph, preview, and export audit before claiming every cached font file works in QCut.

Use this binary route only as a local oracle, optional private adapter, and regression reference. Runtime rendering proves pixel execution, not editable QCut semantics. The ABI is private and version-specific, and package assets are not redistributable. A shippable QCut feature must use QCut-owned code and licensed assets.

Reproduce in QCut

Inspect the current QCut boundary before editing:

rg -n "interface TextElement|ResolvedTextStyle|resolveTextStyle" \
  packages/editor-core/src/types/timeline.ts \
  apps/web/src/lib/text \
  apps/web/src/lib/export-cli

Use a versioned structured appearance model when the reference needs multiple fills, strokes, inner shadows, outer shadows, gradients, or textures. Keep one canonical evaluation and rendering contract for editor preview, thumbnails, and export; do not build separate approximations that drift.

Implement in this order:

1. Use the private runtime oracle to establish same-text visual behavior and failure boundaries before implementing a package family.
2. Preserve layer data and normalization without Jianying-owned files.
3. Render solid and gradient glyph fills through the glyph mask.
4. Add ordered multi-stroke and inner/outer shadow composition.
5. Add QCut-owned texture fills with explicit mapping and wrapping semantics.
6. Add an SDF/WebGL path only for behavior that Canvas cannot reproduce.
7. Verify transparent pixels, layer ordering, bounds, seek stability, preview, thumbnail, and export with synthetic fixtures.

Do not extend the flat legacy text fields one special case at a time. Keep a compatibility adapter from existing TextElement styles into the structured model, then make the renderer consume that model.

Required Output

For each researched card, retain:

• visible title, category, card order, account database, endpoint, row timestamp;
• resource ID, MD5, package path, package type, and exact mapping evidence;
• decoded layers, parameter units, texture/runtime dependencies, and ambiguity;
• same-text captures on transparent and high-contrast backgrounds;
• runtime-oracle result, no-effect baseline hash, and fallback classification;
• QCut capability gap, original implementation scope, tests, and asset provenance;
• confidence level and unresolved black boxes.

Call a mapping proven only when catalog identity, local package identity, and rendered behavior agree.
