title-card-image
Renders a centered-text PNG suitable for a cover / ending card before
animating into a clip with video-still-animator.
Inputs (with:)
| key | required | default | notes |
|---|---|---|---|
text |
yes | — | Headline text. Auto-wraps at ~10 chars per line for CJK. |
output |
yes | — | Output .png path. |
subtitle |
no | "" |
Smaller line beneath the headline. |
background |
no | #101018 |
Hex color #RRGGBB. |
text_color |
no | #ffffff |
Headline color. |
font_size |
no | 96 |
Headline font size in pixels. |
subtitle_size |
no | 36 |
Subtitle font size in pixels. |
width |
no | 720 |
Output width in pixels. Match the merge pipeline. |
height |
no | 1280 |
Output height. 720x1280 = 9:16. |
Output
Prints the absolute path of the written PNG on stdout. The PNG is RGB (no alpha), JPEG-quality-equivalent file ~30-80 KB depending on text length.
Font fallback
Tries --font if explicit, else walks a CJK-aware list of platform
defaults (Microsoft YaHei / SimHei on Windows, PingFang on macOS, Noto
CJK / WenQuanYi on Linux). If nothing loads, falls back to Pillow's
bundled bitmap font — CJK characters render as squares ("tofu") in that
worst-case but the program never crashes.
Limits
- No alpha / transparency.
- No rich text styling (italic / drop-shadow / gradient). For richer
cards, generate a real image via
nano-banana-proinstead. - Headline wrap is character-count-based for CJK and whitespace-based for ASCII; mixed strings break at the CJK character count.
