p-video

Use when someone wants a simple short clip from text or images — quick B-roll, drafts, or start/end frame animation. Not when the brief needs cinematic generation, highest quality, tight lip-sync, or imported audio at 1080p.

Prerequisites

Install and load these skills before generating (skip if already in context via @pruna):

Skill	Description	Install
generation-diversity	Use when writing any generative prompt — ritual seed, explicit structure, scenario axes, and quality gates before paid API calls.	npx skills add PrunaAI/pruna-skills@generation-diversity -y
video-prompting	Use when crafting video or motion prompts for any generative model — dramaturgy, camera, physics-safe motion, frame anchors, and clip chaining.	npx skills add PrunaAI/pruna-skills@video-prompting -y
audio-prompting	Use when crafting TTS, music, or bed prompts for any generative audio model — director style, song structure, and post-production layering.	npx skills add PrunaAI/pruna-skills@audio-prompting -y
pruna-api	Use before any Pruna or Replicate HTTP call — credentials, upload/poll/download, parallel batches, and agent safety.	npx skills add PrunaAI/pruna-skills@pruna-api -y

Or install the full suite once: npx skills add PrunaAI/pruna-skills@pruna -y

Follow each skill's Before generating / craft sections — do not restate guide content here.

Agent habit

Routing: Use `p-video` for simple, quick clips — drafts, light B-roll, short motion. Standard cinematic generation with generated audio → `p-video-2-pro`. Imported image or video references that lock a subject or condition identity/style/motion/timing/performance, with generated audio, audio guidance, or one kept track (keep_audio) → `p-video-2-pro-reference`. 1080p, imported soundtrack, or draft previews → `p-video-2`.

In the first reply, name `p-video` in backticks, confirm PRUNA_API_KEY (or stop with signup links from pruna-api), then ask for required inputs. Open intake → generation-diversity clarification intake before the first POST. When drafting motion prompts, follow Prompt craft (dynamic + faithful) — do not paste skill examples. Redirect when When NOT to use fits better.

Prompt craft (dynamic + faithful)

Every input.prompt must be fresh and specific, and must match the user's beat. Diversity never overrides the brief.

Do	Don't
Run the generation-diversity random seed ritual; state it; rotate ≥2 free axes (camera move, lighting shift, texture, pacing) when the brief allows	Copy curl examples from this skill (rain-slick street, dog tosses plush, …) or reuse a prior session's prompt
Lock user-required facts first (subject, action beat, OPEN/MID/CLOSE when frame-anchored, narration sync when audio is set)	Swap the subject or motion for a “cooler” clip that ignores the request
Structure with video-prompting dramaturgy — one frozen action per beat, physics-safe motion, camera grammar	Vague mood-only strings (cinematic vibe, neon energy)
When audio is set, motion and pacing must match the narration beat	Drift to unrelated action while VO plays
Show the drafted prompt + mode fields before POST when the user has not locked wording	Silent regen with a different subject or beat than approved

Fidelity check (before pay): if you remove the user's named subject/action/setting from the prompt, the job is wrong — rewrite. Free axes only fill what the brief left open.

When showing a drafted prompt, still name `p-video` (guides help craft; this tool owns the call).

Skill boundary

This skill = one p-video prediction per invocation.

Out of scope (do not execute from this skill):

• Multi-scene assembly, concat, subagent orchestration, or parallel scene batches
• Motion transfer from a template video → p-video-animate
• Talking-head-only / lip-sync host without native scene audio → p-video-avatar
• Cinematic generation with generated audio → p-video-2-pro
• 1080p, imported audio, or draft previews → p-video-2

If the request exceeds one clip, stop and recommend: image-to-video (one narrated beat), visual-transition-reel (multi-scene visual), or narrated-multi-scene (multi-scene + VO).

When NOT to use

Use a different skill instead:

Skill	Description	Install
p-video-2-pro-reference	Use when someone wants one cinematic clip that locks a subject from references — a product still, character, clip, or voice — using image or video references plus optional audio kept as the soundtrack or used as guidance. Not for text-only generation, 1080p, or drafts.	npx skills add PrunaAI/pruna-skills@p-video-2-pro-reference -y
p-video-2-pro	Use when someone wants a cinematic clip from text or start/end frames — product ads, documentary shots, or dialogue with generated audio. Not for 1080p, imported audio tracks, or talking-head-only hosts.	npx skills add PrunaAI/pruna-skills@p-video-2-pro -y
p-video-2	Use when someone wants a polished short clip from text, images, or imported audio — 1080p B-roll, start/end frame animation, or a motion shot with a mixed track. Not for cinematic generated-audio clips or talking-head-only hosts.	npx skills add PrunaAI/pruna-skills@p-video-2 -y
p-video-avatar	Use when someone wants a person on camera speaking a script — lip-synced host, spokesperson, or narrated avatar from a portrait photo.	npx skills add PrunaAI/pruna-skills@p-video-avatar -y
p-video-animate	Use when someone wants a photo to move like another video — motion transfer, dance remixes, or performance variations from a template clip.	npx skills add PrunaAI/pruna-skills@p-video-animate -y
p-video-replace	Use when someone wants to swap a person, outfit, or product inside existing footage while keeping the camera move and audio.	npx skills add PrunaAI/pruna-skills@p-video-replace -y
p-video-edit	Use when someone wants to edit an existing video with a text instruction — recolor, restyle, remove or add objects, change environment or lighting, update on-screen text, or apply optional reference-guided product and accessory edits. Not for a new clip from scratch or ffmpeg assembly.	npx skills add PrunaAI/pruna-skills@p-video-edit -y
video-editing	Use when assembling or polishing already-rendered clips with ffmpeg — concat, crossfades, burned captions and subtitles, text/logo overlays, before/after sliders, background music beds, platform export — or when composing a multi-layer HTML combination video with Hyperframes. Not for AI video generation, prompt craft, or model-based video edits.	npx skills add PrunaAI/pruna-skills@video-editing -y

Omit duration when audio is set. Clip length = min(audio length, 20s) — keep TTS ≤ ~19s (ffprobe before render).

Before generating

1. Complete Prerequisites guide reading order (generation-diversity → video-prompting).
2. Ritual seed → draft a dynamic + faithful motion prompt (section above) → confirm mode (T2V / I2V / frame pair / audio), duration (unless audio-driven), resolution, fps, draft, and prompt with the user.
3. Pruna notes: when image is set, aspect_ratio is ignored. With audio, omit duration and set save_audio: true to keep narration. Prefer uploaded VO over post-mux. If the request is multi-scene — stop (see Skill boundary).
