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.

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`
`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

In the first reply, name `p-video-edit` in backticks, confirm PRUNA_API_KEY (or stop with signup links from pruna-api), then ask for the source video (max 15s) and edit brief. Open intake → generation-diversity clarification intake before the first POST. Draft edits with Prompt craft (dynamic + faithful) — do not paste skill examples. Redirect when When NOT to use fits better.

Prompt craft (dynamic + faithful)

prompt is surgical and request-locked. One principal change per run. Describe the desired final state, then name what must stay unchanged. Change only what the user asked; keep camera, motion, audio, and unmentioned elements identical.

Do	Don't
Formula: `Change only [X]. Preserve [geometry / motion / camera / lighting / unmentioned subjects].`	Vague `make it better` / mood-only rewrites that invent a new scene
Name every must-keep from the user (subject, camera path, lighting, props)	Drop keep-clauses and hope the model preserves them
Ritual seed before drafting; fresh wording for keep clauses when the brief allows	Copy this skill's sample (`sunset sky`) when the user described a different edit
Point at refs when used: `add the accessory from the first reference`	Vague `use the reference` with no source slot
Show `prompt` before `POST` when wording is not locked	Silent edit that changes camera, cast, or unrequested regions

Fidelity check (before pay): the prompt must still satisfy the user’s change and every stated keep. Do not “spice” extras when they asked for one attribute or environment edit.

Weak jobs (avoid or warn): a brand-new scene/plot; adding an object with its own independent motion (especially a new in-hand shape); changing camera angle, camera motion, or zoom.

Skill boundary

	p-video-edit	p-video-replace
User question	Change the color / environment / object / text / lighting in this clip?	Replace this person in this video?
Goal	Instruction edit of the source clip	Swap identity into existing footage
Reference images	Optional `images` — 0 to 4	Required `images` — 1 to 4
Prompt field	`prompt`	`instruction_prompt`

Use p-video-replace when the job is a character swap from required reference stills. Use this skill for prompt-driven attribute, environment, object, text, or lighting edits.

When NOT to use

Use a different skill instead:

Skill	Description	Install
`p-video-2`	Use when someone wants the best-quality short clip from text, images, or audio — polished B-roll, start/end frame animation, or a motion shot with stronger lip-sync. Not for full multi-scene films or talking-head-only hosts.	`npx skills add PrunaAI/pruna-skills@p-video-2 -y`
`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 the highest quality or tight lip-sync.	`npx skills add PrunaAI/pruna-skills@p-video -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-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`
`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`

HTTP (curl)

Upload source video

bash

curl -X POST "https://api.pruna.ai/v1/files" \
  -H "apikey: ${PRUNA_API_KEY}" \
  -F "content=@/path/to/source-video.mp4"

Use the response urls.get in input.video. Source video maximum length: 15 seconds.

Optional reference images

bash

curl -X POST "https://api.pruna.ai/v1/files" \
  -H "apikey: ${PRUNA_API_KEY}" \
  -F "content=@/path/to/reference-image.png"

Use each response urls.get in input.images (up to 4; jpg, jpeg, png, webp).

Create (async — recommended)

bash

curl -X POST 'https://api.pruna.ai/v1/predictions' \
  -H 'Content-Type: application/json' \
  -H "apikey: ${PRUNA_API_KEY}" \
  -H 'Model: p-video-edit' \
  -d '{
    "input": {
      "video": "https://api.pruna.ai/v1/files/source-video-abc123",
      "prompt": "Change only the sky to a sunset. Preserve the subject, camera path, and lighting on the foreground."
    }
  }'

Poll and download: follow pruna-api. Output duration follows the source video. Billing is per returned second ($0.045 standard, $0.025 draft). Rate limit: 50 requests per minute.

Complete the random seed ritual from generation-diversity before writing prompts — do not pass the ritual string as API seed. Optional seed only when the user requests reproducibility.

Create (sync — quick test only)

bash

  -H 'Model: p-video-edit' \

Before generating

Complete Prerequisites guide reading order (generation-diversity → video-prompting).
Ritual seed → draft a dynamic + faithful prompt (section above) → confirm video (≤15s), prompt, optional images (0–4), draft, save_audio, and edit intent (attribute / remove / add / environment / relight / text / reference-guided).
Pruna notes: one principal change per run. Identity or product match comes from optional images; the edit instruction lives in prompt. Vague targets and brand-new scenes drop quality. Do not send a task field — it is not in the public API.

Required input

video (string URL): source video to edit. Maximum length: 15 seconds
prompt (string): text instruction describing the edit

Common optional fields

images (array of up to 4 string URLs): reference image(s) for reference-guided editing (jpg, jpeg, png, webp)
prompt_upsampling (boolean, default true)
draft (boolean, default false): faster, lower-quality preview; billed at $0.025 per output second
save_audio (boolean, default true)
seed (integer): set only for reproducible reruns
