長尺動画から字幕付きクリップを一括作成

長尺動画を、字幕付きの短いクリップN本に分割します。動画全体の文字起こしは一度だけ行い、AIが見どころを選び、各クリップのトリミングと字幕付けを並列で処理します。TikTok、Reels、Shorts向けの縦型（9:16）、Instagram向けの正方形（1:1）や縦長（4:5）への変換も可能で、字幕位置は画面比率に合わせて自動調整されます。

--input必須
asset_url既定値—Source video: a YouTube or social URL, a direct media URL, a local file, or an existing pipe2 asset. Remote and local sources are uploaded automatically; use --asset <id> or --no-fetch when the asset is already available.
--reformat
enum既定値Optional output aspect ratio. Leave empty to preserve the source's native aspect (default: fastest, cheapest). Set to 9:16 for TikTok/Reels/Shorts, 1:1 or 4:5 for Instagram, 16:9 for horizontal YouTube cards from a vertical source.

9:161:14:516:9
--highlights-count
int既定値5How many moments to pick when highlights runs (auto mode). Ignored if --clips is set.
--highlights-style
string既定値Natural-language steer for the highlights picker: e.g. "the funniest moments", "the strongest arguments". Empty uses the picker's default.
--clips
string既定値Optional path to a JSON file overriding the auto-picker, shaped [{"context": "...", "start_sec": 42.5, "end_sec": 78.0}, ...]. When set, the highlights step is skipped. Leave empty to let the highlights pipeline pick automatically.
--corrections
string既定値Comma-separated word-boundary substitutions applied to the transcript, in the form "from=to,from=to". Use it when the recognizer mis-hears the same word the same way every time (a name, an acronym, a domain term). To preserve a phrase that contains a substring you also want to rewrite, declare the longer phrase first as a no-op ("phrase=phrase,word=replacement"): longer matches win, so the phrase is shielded before the bare-word rule fires. Case-sensitive.
--lang
string既定値enISO 639-1 transcription language, or 'auto'.
--no-watermark
bool既定値falseShip the output unbranded. Skips the watermark step entirely.
--parallel
int既定値4Max number of clips to process in parallel.
--position
enum既定値autoVertical caption position. "auto" (default) keeps text away from the main subject when possible and otherwise places it at the bottom. Set a position explicitly to override.
auto · top · middle +1
autotopmiddlebottom
--preset
enum既定値serif-editorialCaption styling preset for every clip.

--watermark-scale
int既定値20Watermark width as a percentage of the video width.
--watermark-url
asset_url既定値Override the default Pipe2 logo with your own image (URL or local path). Empty means use the bundled Pipe2 watermark.
--watermark-variant
enum既定値lightWhich bundled Pipe2 logo to use when --watermark-url is empty. "light" for dark videos, "dark" for bright ones; coloured variants match the clip palette.

    入力元: OpenClaw Creator, Why 80% of Apps Will Disappear
    テキスト 
    00:00:00,180  Today, I'm sitting down with Peter Steinberger, the creator of OpenClaw, the open source personal AI agent that has completely taken over the internet.
00:00:09,060  The GitHub repo exploded to over 160,000 stars practically overnight.
00:00:14,130  The community has built countless projects, like Malt Book, where bots talk among themselves.
00:00:19,560  And now, the bots are even renting humans to do tasks in the real world.
00:00:24,220  In our conversation, we discuss his aha moment, his contrarian development philosophies, and what this means for builders in 2026.
00:00:32,740  Let's dive in.
00:00:38,980  So good to see you, man.
00:00:39,960  Hey, what's up?
00:00:40,760  Um, so you've made something people want.
