Also handles the final composite step for the localization pipeline — burn subs, mix a dub track, and keep the original audio as a low-volume bed, all in ONE ffmpeg encode (no cascade). Verifies libass availability and auto-downloads a static evermeet ffmpeg build when Homebrew's stripped binary lacks it. Triggers — \"烧字幕\", \"硬字幕\", \"burn subtitles\", \"burn-in subs\", \"embed subtitle\", \"soft mux SRT\", \"把字幕烧进视频\", \"做最终合成\".\n---\n\n# wjs-burning-subtitles\n\nVideo + SRT → video with subtitles. Also the final-encode stage for the localization pipeline: takes a video, an optional dub track from `/wjs-dubbing-video`, and an optional SRT to burn, and produces the upload-ready MP4 in **one** ffmpeg pass. No cascade of decodes/re-encodes.\n\n## When to use\n\n- User has an SRT and wants it always-visible on the video (burn-in for 微信视频号 / 抖音 / WeChat — players that won't honor embedded subtitle tracks).\n- User wants a togglable subtitle track (soft-mux) for QuickTime / VLC / IINA / mobile players that support `mov_text`.\n- Final composite after `/wjs-dubbing-video`: burn target-language subs + mix dub over original-as-bed in one encode.\n\n## When NOT to use\n\n- No SRT yet → run `/wjs-transcribing-audio` then `/wjs-translating-subtitles` first.\n- HTML/CSS captions (kinetic, per-word highlights, custom fonts) on a clip composed in HyperFrames → use `/wjs-overlaying-video` instead. Don't mix libass burn-in with HyperFrames captions on the same output.\n- The \"subtitles\" are actually motion graphics (animated callouts, lower-thirds with logos, kinetic typography) → that's `/wjs-overlaying-video`, not this skill.\n\n## The 3 modes of `render.py`\n\n`scripts/render.py` auto-detects mode from flags:\n\n1. **Subtitles only** — `--video + --srt` → re-encodes video with burned subs, original audio passes through.\n2. **Dub only** — `--video + --dub` → keeps original video stream; replaces or mixes the audio track.\n3. **Full localized cut** — `--video + --srt + --dub` → burns subs AND mixes dub. By default keeps original audio at low volume as a \"bed\" under the dub (set `--bed-volume 0` or `--no-original-audio` to drop it).\n\nBurn-in requires an ffmpeg built with libass. The script auto-downloads a static libass-enabled build from evermeet.cx into `/tmp/ff_bin/` on first use if needed.\n\n## Soft-mux (togglable subtitle track)\n\nPlayer apps can show/hide. Works with any `ffmpeg` build — does **not** need libass:\n\n```bash\nffmpeg -i input.mp4 -i input.zh-CN.srt \\\n -map 0:v -map 0:a -map 1:0 \\\n -c:v copy -c:a copy -c:s mov_text \\\n -metadata:s:s:0 language=zho -metadata:s:s:0 title=\"中文\" \\\n output.mp4\n```\n\nThis is fast (stream-copy) and reversible. Use it when:\n\n- Target platform supports embedded subs (YouTube auto-detects; VLC/QuickTime honors).\n- User wants viewers to be able to toggle off.\n- You don't want to re-encode the video.\n\n`render.py --video IN.mp4 --srt SUB.srt --soft-mux` runs this path.\n\n## Hardcoded burn-in (always visible, libass)\n\nRequired for WeChat/抖音/朋友圈 etc. where the player will not honor embedded subtitle tracks.\n\n### Verify libass is available BEFORE promising burn-in\n\n```bash\nffmpeg -filters 2>&1 | grep -E \"subtitles|^.. ass \"\n```\n\nIf neither `subtitles` nor `ass` shows up, the build lacks libass. Homebrew's default `ffmpeg` formula is often stripped (no `--enable-libass`, no `--enable-libfreetype`, no `drawtext`). Don't waste time fighting the comma-escaping inside `force_style` — it will fail with `No such filter: 'subtitles'` no matter how the shell quotes it.\n\n### Fastest fix on macOS — drop in a static build, no system changes\n\n```bash\ncurl -fsSL -o /tmp/ff.zip https://evermeet.cx/ffmpeg/getrelease/zip\nunzip -o /tmp/ff.zip -d /tmp/ff_bin >/dev/null\nFF=/tmp/ff_bin/ffmpeg\n$FF -version | grep -oE -- \"--enable-(libass|libfreetype)\"\n```\n\nThen use `$FF` instead of `ffmpeg` for the render. The brew binary is fine for everything else (probe, audio extraction, soft-mux). `render.py` does this auto-fallback if its default ffmpeg lacks libass.\n\n### Burn-in render with style overrides\n\n🛑 **Checkpoint — confirm before full-render.** Burn-in re-encodes the entire video (minutes of CPU on a 5-min clip). Before kicking it off:\n\n1. Render only the first 30s with `-t 30` for a fast preview.\n2. Extract a frame from the longest-line cue (see Fontsize calibration below) and Read it.\n3. Show the user the preview frame + the cue text, ask: \"字号/字体/边距 OK 吗？OK 才跑全片。\" Wait for explicit confirmation.\n\nSkip the checkpoint only if the user has already approved a full render of this exact video at this exact font config in the same conversation.\n\n```bash\n$FF -i input.mp4 \\\n -vf \"subtitles=input.zh-CN.srt:force_style='Fontname=PingFang SC\\,Fontsize=12\\,PrimaryColour=&H00FFFFFF\\,OutlineColour=&H00000000\\,BorderStyle=1\\,Outline=2\\,Shadow=1\\,MarginL=20\\,MarginR=20\\,MarginV=40'\" \\\n -c:v libx264 -crf 18 -preset medium -pix_fmt yuv420p \\\n -c:a copy output.mp4\n```\n\nInside `force_style`, escape every comma as `\\,` (the filter graph parser eats the bare comma as a chain separator). All other special chars are fine.\n\n### Fontsize calibration — critical\n\nlibass scales its internal PlayRes up to the actual video resolution. The number you pass is **not pixels** in the output. As a starting calibration on a 544×960 vertical phone video, `Fontsize=22` rendered each Chinese character at ~55px wide and overflowed the frame, while `Fontsize=12` rendered at ~30–35px wide and fit cleanly with 15-char lines.\n\nRule of thumb: start at `Fontsize=12`, render, then **always** extract a frame and look:\n\n```bash\n$FF -ss 30 -i output.mp4 -frames:v 1 /tmp/frame.png -y\n# then Read /tmp/frame.png to verify the longest-line cue fits\n```\n\nPick a timestamp that lands on the cue with the most characters per line — short lines won't expose overflow. Add `MarginL=20 MarginR=20` as a safety inset; never trust default left/right margins.\n\n### Style cheatsheet\n\nKeys that matter (libass `force_style`):\n\n- `Fontname=PingFang SC` — macOS default CJK; alternates: `Songti SC`, `Heiti SC`, `STHeiti`, `Hiragino Sans GB`.\n- `Fontsize=12` — start small, scale up only after frame check.\n- `PrimaryColour=&H00FFFFFF` — white text (BBGGRR + alpha).\n- `OutlineColour=&H00000000` — black outline.\n- `BorderStyle=1` — outline only (clean over varied backgrounds). Use `BorderStyle=3` for an opaque box behind text when the background is busy.\n- `Outline=2` — 2px outline thickness.\n- `Shadow=1` — subtle drop shadow.\n- `MarginL=20 MarginR=20` — keep text inside the frame.\n- `MarginV=40` — vertical distance from the bottom edge.\n\n### SRT line-length discipline for burn-in\n\nEven with correct `Fontsize`, lines that are too long will wrap or overflow. Keep each on-screen line ≤ ~15 Chinese characters (~42 Latin chars). Use explicit `\\n` line breaks inside the SRT block — do not rely on auto-wrapping. Two short lines beat one long one every time. (This is upstream discipline — `/wjs-translating-subtitles` should already cap cues at these limits.)\n\n## Audio mixing — keep the original as a low-volume bed\n\nA pure dub-only track sounds dubbed (because it is). Mixing the original audio at low volume under the dub gives the \"professional translation\" feel — you still hear the speaker's breath, emphasis, and laughter, just under the new voice.\n\n```bash\n$FF -i original.mp4 -i dub.mp4 \\\n -filter_complex \"[0:a]volume=0.18[orig];\\\n [1:a]volume=1.0[dub];\\\n [orig][dub]amix=inputs=2:duration=longest:normalize=0[a]\" \\\n -map 0:v -map \"[a]\" \\\n -c:v copy -c:a aac -b:a 192k mixed.mp4\n```\n\nReasonable starting volumes:\n\n- Original bed at `0.15`–`0.25` (≈ −16 to −12 dB)\n- Dub at `1.0`\n- Use `normalize=0` so amix doesn't auto-attenuate when both are active.\n\nTo drop the original entirely: `--no-original-audio` (equivalent to `--bed-volume 0`).\n\n## Combining dub + burn-in + bed (the full job)\n\nOne ffmpeg call does all three — burn the target subtitle onto the video stream and mix the two audio tracks:\n\n```bash\n$FF -i original.mp4 -i dub.mp4 \\\n -filter_complex \"[0:v]subtitles=input.zh-CN.srt:force_style='Fontname=PingFang SC\\,Fontsize=12\\,PrimaryColour=&H00FFFFFF\\,OutlineColour=&H00000000\\,BorderStyle=1\\,Outline=2\\,Shadow=1\\,MarginL=20\\,MarginR=20\\,MarginV=40'[v];\\\n [0:a]volume=0.18[orig];[1:a]volume=1.0[dub];\\\n [orig][dub]amix=inputs=2:duration=longest:normalize=0[a]\" \\\n -map \"[v]\" -map \"[a]\" \\\n -c:v libx264 -crf 18 -preset medium -pix_fmt yuv420p \\\n -c:a aac -b:a 192k final.mp4\n```\n\nThis is the \"ship to social media\" final cut. `render.py --video original.mp4 --dub dub.mp4 --srt input.zh-CN.srt` runs this exact pipeline.\n\n## Running `render.py`\n\n```bash\n# Subtitles only (burn):\npython3 ~/.claude/skills/wjs-burning-subtitles/scripts/render.py \\\n --video IN.mp4 --srt SUB.srt --out OUT.mp4\n\n# Dub only (replace audio, no subs):\npython3 ~/.claude/skills/wjs-burning-subtitles/scripts/render.py \\\n --video IN.mp4 --dub IN_zh_dub.mp4 --out OUT.mp4\n\n# Full localized cut (burn + dub + original bed):\npython3 ~/.claude/skills/wjs-burning-subtitles/scripts/render.py \\\n --video IN.mp4 --srt IN.zh-CN.srt --dub IN_zh_dub.mp4 --out OUT.mp4\n\n# Soft-mux (no re-encode):\npython3 ~/.claude/skills/wjs-burning-subtitles/scripts/render.py \\\n --video IN.mp4 --srt SUB.srt --soft-mux --out OUT.mp4\n```\n\nSee `render.py --help` for the full style/audio flag list (`--font`, `--fontsize`, `--color`, `--outline-color`, `--margin-v`, `--bed-volume`, `--no-original-audio`).\n\n## Output\n\n- Burn mode: `_burned.mp4` (re-encoded, libass-rendered subs)\n- Soft-mux mode: `_softsub.mp4` (stream-copy, `mov_text` track)\n- Full cut: `_final.mp4` (re-encoded video with burned subs + mixed audio)\n\n## Anti-patterns\n\n- ❌ **Promising burn-in without verifying libass.** Check `ffmpeg -filters | grep subtitles` first; auto-fall back to evermeet static build if missing.\n- ❌ **Committing a burn render without a frame check.** Always extract a frame at the longest-line cue and Read it before kicking off the full render.\n- ❌ **Bare commas inside `force_style`.** The filter graph parser eats them. Escape every internal comma as `\\,`.\n- ❌ **Mixing libass burn-in with HyperFrames captions.** Pick ONE caption system per output video. If you're using HTML/CSS captions in `/wjs-overlaying-video`, don't burn here too.\n- ❌ **Using period milliseconds in the SRT.** Whisper local writes `.mmm`; libass tolerates it but other downstream tools choke. Normalize to `,mmm`.\n- ❌ **Defaulting to `BorderStyle=3` (opaque box).** Use `BorderStyle=1` (outline only) unless the background is genuinely busy — the box looks heavy and dated.\n\n## Upstream\n\n- **`/wjs-transcribing-audio`** + **`/wjs-translating-subtitles`** — produce the SRT input.\n- **`/wjs-dubbing-video`** — produces the `*__dub.mp4` input for full-localized-cut mode. The dub-only file is technically a finished video; this skill is what mixes the original underneath and burns the subs to make it shippable.\n\n## Common pitfalls\n\n- **Fontsize that worked on one video looks tiny / huge on another.** libass scales by PlayRes ratio, not pixels. Recalibrate per video resolution; don't trust a hardcoded value.\n- **Margin defaults clip text on vertical phone videos.** Always set `MarginL=20 MarginR=20` and `MarginV=40` (or higher) explicitly.\n- **`mov_text` track shows up in QuickTime but not in some Android players.** If the target audience is mobile-Chinese, soft-mux is unreliable; burn instead.\n- **Background-bus busy / contrast issues.** Increase `Outline=2` → `Outline=3`, or switch to `BorderStyle=3` for a translucent box (`BackColour=&H80000000` for 50% black).\n","tagline":"Use when the user has a video + an SRT and wants the subtitles either burned into the pixels (libass, always-visible) or soft-muxed as a togglable track.
