That is enough to judge a take, and short of what a 1080p feed or a 4K edit expects. P-Video-Upscale is **the finishing step**: it takes the generated clip by its UUID and returns it at 1080p, 2K or 4K, with the soundtrack the generation produced still attached. **Generated, 768p**: [Watch video](https://runware.ai/docs/assets/source-serum.D2gnecuz.mp4) **Upscaled, 4K**: [Watch video](https://runware.ai/docs/assets/output-serum-4k.mMkxHDkr.mp4) The serum shot above came out of P-Video-2-Pro at 768p and went through a second request at `4k`. The page plays both halves at the same size, so the gain is clearest **at 100%**, on the same patch of the bottle from each clip: ![A close crop of the pipette tip inside the amber bottle and the base of the bottle in the water, from the 768p render, with soft edges](https://runware.ai/docs/assets/crop-serum-source.BP0FHP7d_2i3pnU.jpg) *768p render · same region, enlarged* ![The same crop from the 4K upscale, with a crisp pipette tip, small bubbles in the serum and a sharp waterline around the bottle](https://runware.ai/docs/assets/crop-serum-4k.BDccp6pn_Z1BssND.jpg) *4k upscale · 100% crop* The 768p render was already clean, so the gain is in **the finest edges**: the pipette tip and the small bubbles suspended in the serum come through crisp at 4K. This guide covers chaining the two requests, the clip lengths that fit a 4K finish, and whether to render at 480p or 768p before the upscale. The upscale request on its own, with every preset size, is in [upscaling video](https://runware.ai/docs/models/prunaai-p-video-upscale/guides/upscaling-video). ### [Chaining the two requests](https://runware.ai/docs/models/prunaai-p-video-upscale/guides/upscaling-generated-video#chaining-the-two-requests) Generate the clip as usual. The response carries a `videoUUID`, and that UUID **goes straight into `inputs.video`** of the upscale, so the clip never has to be downloaded and sent back between the two steps. **TypeScript**: ```typescript import { createClient } from '@runware/sdk' const client = await createClient({ apiKey: process.env.RUNWARE_API_KEY }) await client.connect() const [result] = await client.run({ model: 'prunaai:p-video@2-pro', deliveryMethod: 'async', positivePrompt: 'A glass dropper bottle of amber facial serum stands on a wet slab of dark slate while slow ripples spread across a shallow film of water around its base, and a single clear drop falls from a glass pipette above into the water.

The 1344 × 768 clip came back at 3808 × 2176, the 4K pixel budget for that shape, with the audio P-Video-2-Pro generated carried over unchanged. ### [Fitting a 4K finish](https://runware.ai/docs/models/prunaai-p-video-upscale/guides/upscaling-generated-video#fitting-a-4k-finish) At `4k` the model processes **at most 300 frames**, and P-Video-2-Pro returns a clip **near the `duration` you ask for** rather than exactly on it. Both matter when you plan a 4K finish, because the margin is small. | `duration` | Frames returned at 24 fps | `4k` at the source rate | `4k` at 30 or 60 fps | | --- | --- | --- | --- | | `5` | 124 | Fits | Fits | | `8` | 192 | Fits | Fits | | `10` | 243 | Fits | Rejected, 304 frames | | `15` | about 345 | Rejected | Rejected | At the source rate every render up to 10 seconds fits. Raise the frame rate on the same pass and the frames are counted at 30 per second, so a 10-second render, which comes back at 10.125 seconds, **lands at 304 frames and is rejected**. Keep 4K renders at 8 seconds or less when you also ask for 30 or 60 fps, and send 15-second renders to `2k`, which takes them at any rate. Frame rates are covered in [raising the frame rate](https://runware.ai/docs/models/prunaai-p-video-upscale/guides/raising-the-frame-rate). ### [Rendering at 480p or 768p](https://runware.ai/docs/models/prunaai-p-video-upscale/guides/upscaling-generated-video#rendering-at-480p-or-768p) A 1080p finish can start from either P-Video-2-Pro tier, so the choice is **where the detail comes from**: the render or the upscale. The two takes below are `quality` renders of one prompt on one seed with the expander off. One rendered at 640 × 480, the other at 1024 × 768, and both were upscaled to 1080p. **480p**: [Watch video](https://runware.ai/docs/assets/source-hotel-draft.PAYfBIlG.mp4) *480p, quality mode* > **Prompt**: A slow gimbal push into a bright boutique hotel room as sheer white curtains drift in the breeze, a king bed with crisp white linen and a woven rattan headboard, a terracotta tiled floor, a pair of cane armchairs by open glass doors, and a balcony beyond with a view of the sea. Soft morning daylight, crisp detail in the linen weave, the rattan and the tiles. Photoreal hospitality marketing video, smooth steady forward motion, no text, no logos, no people. Audio: a light sea breeze, distant waves, no music. **480p → 1080p**: [Watch video](https://runware.ai/docs/assets/output-hotel-draft-1080p.z3fItTfu.mp4) *480p render, upscaled to 1080p* **768p**: [Watch video](https://runware.ai/docs/assets/source-hotel-final.XNUw4aKu.mp4) *768p, quality mode* > **Prompt**: A slow gimbal push into a bright boutique hotel room as sheer white curtains drift in the breeze, a king bed with crisp white linen and a woven rattan headboard, a terracotta tiled floor, a pair of cane armchairs by open glass doors, and a balcony beyond with a view of the sea. Soft morning daylight, crisp detail in the linen weave, the rattan and the tiles. Photoreal hospitality marketing video, smooth steady forward motion, no text, no logos, no people. Audio: a light sea breeze, distant waves, no music. **768p → 1080p**: [Watch video](https://runware.ai/docs/assets/output-hotel-final-1080p.5v6KsWCR.mp4) *768p render, upscaled to 1080p* They are **two different rooms**. On this prompt the seed did not carry the take across tiers: the 480p render kept the armchairs inside by narrow glass doors, and the 768p render opened the wall into sliding doors with the chairs out on the balcony. So the tier is part of the take, and **a shot you pick at 480p is the shot you deliver**, upscaled, rather than one you can render again at 768p. Changing mode starts a new take as well, as the [P-Video-2-Pro guide to speed, quality and size](https://runware.ai/docs/models/prunaai-p-video-2-pro/guides/speed-quality-and-size) covers. Compare texture rather than framing, and both upscales hold up at 1080p. The cane on the headboards and the armchairs reads as woven in both, and the 768p take keeps **the finer, crisper weave**, because it started with more of it. The 480p route costs close to half per rendered second and finishes a little softer at 100%, which is a fair trade for a feed and a poor one for a hero shot. ### [Tips](https://runware.ai/docs/models/prunaai-p-video-upscale/guides/upscaling-generated-video#tips) 1. **Pass the `videoUUID` along.** The upscale takes it directly in `inputs.video`, so there is nothing to download and upload between the two requests. 2. **Plan 4K renders at 10 seconds or less.** Drop to 8 if the same pass raises the frame rate, and send longer renders to `2k`. 3. **Pick the shot at the tier and in the mode you deliver in.** The same seed came back as a different take at 480p and at 768p here, and a change of mode starts a new take too. 4. **Upscale once, to the size you deliver.** A 1080p feed does not need a 4K pass, and the 4K cap is the tightest on length. 5. **Raise the frame rate on the same pass.** `fps` goes in the upscale request, so a 24 fps render can come back at 30 or 60 without a third step.
