It always operates on a selected **catalog**: products come from the catalog, generation history is kept per catalog, and results save back to catalog items. If you don't have a catalog yet, start with the [Catalogs Quickstart](/catalogs/quickstart). ## Tools | Tool | What it does | Key controls | | ---------- | ------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------- | | **Images** | Generates edited versions of the selected product image from your prompt | **Fast / Slow** quality toggle, **Images** count (1–20), reference image via drag & drop | | **Video** | Turns the product image into a short clip | Duration **5s / 10s / 15s**, optional end-frame image via drag & drop | ### Quality: Fast vs Slow The **Fast / Slow** switch picks the model tier for image generation: * **Fast** — quickest and cheapest; great for iterating on prompt ideas. * **Slow** (default) — the highest-quality model; use it for final shots. ### Multiple options per run Set **Images** to generate up to 20 candidates from one prompt. Each generated image is billed separately, so 4 images cost 4× the single-image price. Generating a handful and picking the best result usually beats re-prompting one at a time. ### Reference images Drag any image into the prompt box to guide the generation: * **Images tool** — the drop becomes a *style/context reference* alongside your prompt. * **Video tool** — the drop becomes the *end frame*, and the clip animates from the product image toward it. ## Prompt templates Click **Templates** in the toolbar to open the **Template Library** — ready-made prompts for common product shots (lifestyle context, e-commerce hero on white, detail close-ups, resolution enhancement, marketplace image sets, and more). Selecting a template fills the prompt box; you can edit it before applying. To reuse a prompt you've written, type it in the prompt box, open **Templates**, give it a name under **Save Current Prompt**, and click **Save**. Templates are shared across your organization. Photo Studio Template Library popover showing built-in prompt templates and the Save Current Prompt field ## Results and history The left panel's **Results** tab is the generation history for the selected catalog. Each run shows its input → output thumbnails, the prompt, a relative timestamp, and a status dot (blue pulsing = processing, green = completed, red = failed). Hover a run to **pin** it (pins are shared with your team) or **delete** it. Click any completed run to reopen its result on the canvas: * **Download** the file * **View full size** * **Save to catalog** (see below) * **Trim** (videos only) — cut the clip before downloading or saving Photo Studio results view showing a finished product video with download and trim controls and the run history on the left ## Saving results to your catalog Saving a result attaches it to the product it was generated from: * Images are **appended to the item's `image_urls`** gallery; videos go to `video_urls`. * Existing media is never overwritten or removed — saves are additive and deduplicated. * The change is a normal catalog item update, so it's immediately visible in the catalog view, exports, and the [public items API](/catalogs/reference). To make a generated image the product's hero image, reorder the gallery afterwards — `image_urls[0]` is the hero. ## Credits and costs Photo Studio draws from your organization's shared credit balance — the same pool used by enrichment. The left panel always shows **`Credits: / `** for the operation you've configured, before you click **Apply**. You are only charged for **successful** generations. Typical costs: | Operation | Credits | | ---------------------------- | ------------- | | Image generation/edit — Fast | 1–2 per image | | Image generation/edit — Slow | 2–4 per image | | Video — 5s | 10 | | Video — 10s | 20 | | Video — 15s | 30 | See [Credits](/credits) for how balances, allowances, and packs work. ## Working with catalogs * **Catalog required** — every generation and save is scoped to the selected catalog. Use the catalog picker's **Select a catalog** entry to create one on the spot if needed. * **Products vs variants** — for catalogs with [product variants](/catalogs/reference), the layers toggle in the left panel switches between product-level and variant-level views; saves target whichever level you're working on. * **Upload** — the upload button in the left panel accepts loose images and videos and routes them into catalog items. * **Search & pagination** — search across all item fields with the search icon; large catalogs paginate at the bottom of the panel. ## Availability Photo Studio is included on paid plans. On free organizations the **Studio** tab is visible but locked.
