At a glance

Renders landscape videos with the KrillinAI CLI, either the original footage with bilingual subtitles or a dubbed video with target-language subtitles.

  • Burning bilingual subtitles into the original landscape video
  • SKILL.md covers Bilingual Subtitle Video, Dubbed Video, Inputs and Outputs, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Producing a dubbed landscape video with target-language subtitles

What it does

This skill wraps the render-horizontal command of the KrillinAI CLI. The bilingual variant takes the source video and bilingual_srt.srt and writes horizontal_bilingual.mp4. The dubbed variant, selected with --dubbed, takes video_with_tts.mp4 with target_language_srt.srt and writes horizontal_dubbed.mp4. Both outputs are reported through the horizontal_video key in krillinai_manifest.json.

Inputs are --video (omit it when the manifest already has the right one), an optional replacement --audio, --subtitle, a --workdir holding the manifest, and an optional --subtitle-style-file whose JSON overrides are merged into the default style. To confirm a render, the agent checks for terminal JSON with ok set to true, confirms the output has video and audio streams, and can extract a preview frame to check subtitle placement. Binary location and configuration are covered in a separate cli-contract reference.

When your agent uses it

  • Burning bilingual subtitles into the original landscape video
  • Producing a dubbed landscape video with target-language subtitles
  • Adjusting subtitle styling with a JSON override before rendering again

Example prompts

  • “Render the horizontal bilingual version of this project's video with KrillinAI.”
  • “Make the dubbed horizontal video from video_with_tts.mp4 and the target-language subtitles.”
  • “Re-render with my subtitle-style JSON and check the placement on a preview frame.”

Requirements

  • The KrillinAI CLI binary
  • A work directory with krillinai_manifest.json plus the source video and subtitle files

What it can do on your machine

Read from SKILL.md and the folder at commit 837dbb4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

KrillinAI Horizontal Video Renderer loads about 422 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 112 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~422

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

KrillinAI Render Horizontal

Use this skill for render-horizontal. Read skills/krillinai-cli/references/cli-contract.md first for binary location, execution working directory, configuration, and JSON behavior.

Bilingual Subtitle Video

bash
(cd "$KRILLINAI_CWD" && "$KRILLINAI_CLI" render-horizontal \
  --workdir "$WORKDIR" \
  --video "$WORKDIR/origin_video.mp4" \
  --subtitle "$WORKDIR/bilingual_srt.srt")

Dubbed Video

bash
(cd "$KRILLINAI_CWD" && "$KRILLINAI_CLI" render-horizontal \
  --workdir "$WORKDIR" \
  --video "$WORKDIR/video_with_tts.mp4" \
  --subtitle "$WORKDIR/target_language_srt.srt" \
  --dubbed)

Inputs

  • --video: source video, or omit when manifest has the correct input.
  • --audio: optional replacement audio.
  • --subtitle: usually bilingual_srt.srt for bilingual, target_language_srt.srt for dubbed.
  • --workdir: directory containing krillinai_manifest.json.
  • --subtitle-style-file: optional JSON override merged with the default subtitle style.

Outputs

  • horizontal_bilingual.mp4 for the default variant.
  • horizontal_dubbed.mp4 with --dubbed.
  • Both variants are reported through the manifest key horizontal_video.

Verification

  • Require terminal JSON with "ok": true.
  • Confirm output video exists and has video/audio streams.
  • Extract a preview frame when checking subtitle placement.
  • For manifest and error handling, read skills/krillinai-cli/references/cli-contract.md.
