Flux Video Upscale rebuilds a clip toward 4K and asks for one decision before it starts: precise or creative. That single choice changes the result more than the resolution setting does, and getting it wrong is the difference between a face you recognize and a face that has been quietly redrawn.
The model is new in the Picsart AI Playground and appears in the video model picker with a New badge. It takes footage in rather than a prompt, and returns the same clip at a higher resolution with the audio still attached.
One upload, one decision, one rebuild
Flux Video Upscale is a super-resolution model. It reads the clip you give it and regenerates every frame at a larger size instead of stretching the pixels that are already there.
The shape of the job is narrow and worth knowing before you start:
- It takes video in from 480p up and regenerates it at up to native 4K
- It reads Flux 3 output natively, so clips generated with that model are its home ground
- It repairs the imperfections generated footage carries rather than only adding pixels
- It runs in two modes, and the mode is the only real decision you make
The output preserves the aspect ratio of the source, so a vertical clip comes back vertical. The source audio track carries through to the finished file.
The mode choice is the whole model
Most upscalers offer a resolution and nothing else. This one splits into two modes that treat footage in opposite ways, and that split is the reason to reach for it.
- Precise stays faithful to the source and sharpens what is already recorded
- Creative goes further, restoring and inventing fine detail more aggressively
Both return a larger file at the factor you asked for. What separates them is how much license the model takes with the contents of the frame.
Precise mode protects the things people recognize
Precise mode preserves the source exactly. It sharpens the footage without reinterpreting it, which is what keeps identity intact from the first frame to the last.
Reach for precise on:
- Faces and any footage of real people
- Products and packaging
- Brand assets
- Client work where the frame has already been signed off
The trade is restraint. Precise sharpens what the camera recorded rather than adding to it, and that restraint is the entire point on footage where accuracy is the deliverable.
Creative mode invents the detail that was never there
Creative mode restores and invents fine detail far more aggressively. It targets the failures a general-purpose upscaler tends to miss, including smudged faces and the gridded artifacts that show up on textures such as water and grass.
Reach for creative on:
- AI generated footage
- Landscapes and scenery
- Textures like water, grass, fabric and foliage
- Crowds and dense backgrounds
Creative mode does not preserve identity as strictly. Faces and products can drift under it, which is exactly why the precise option exists.
Which mode for which footage
| Footage | Mode | What the mode is protecting or adding |
|---|---|---|
| People on camera | Precise | The face in the output is the face you filmed |
| Products and packaging | Precise | Labels, logos and shapes hold their form |
| Client and brand deliverables | Precise | Nothing in an approved frame gets reinterpreted |
| AI generated clips | Creative | Repairs the soft passages generation leaves behind |
| Landscapes and scenery | Creative | Rebuilds detail across sky, water and terrain |
| Grass, foliage and fabric | Creative | Clears the gridded look textures pick up |
| Crowds and dense backgrounds | Creative | Adds detail to areas too small to have resolved |
The rule underneath the table is short. Precise for anything a viewer would recognize and could compare against the real thing. Creative for everything else.
How far the upscale actually travels
The upscale factor runs from 1.5x to 3x and is measured against the resolution of the source rather than a fixed output size. Starting from an HD clip, that lands roughly at 1080p, 2K and 4K.
Two ceilings shape what comes back:
- The source has to be 2K (2560 x 1440) or smaller. The model upscales toward 4K and does not take 4K going in.
- Output frames cap at roughly 14.4 megapixels. Asking for 3x on a source that is already large lands below the factor you requested.
Clips that break either limit are rejected before processing. Nothing is quietly trimmed or downscaled behind your back, so a rejection is a clear instruction to go back and prepare the source.
The prompt box is optional and steers creative detail only
Flux Video Upscale runs perfectly well with nothing typed. An empty box produces a neutral upscale, which is the normal way to use it.
A short description of what is in the clip gives creative mode something to aim at. Describing a shoreline at dusk points the invented detail toward water and sky rather than leaving the model to work it out alone.
The prompt does not direct an edit the way it would in a video generation model. It steers the kind of detail that gets added, and nothing beyond that.
What to feed it
Source quality sets the ceiling on the result. Compression artifacts limit how much real detail can be recovered, so the least compressed copy you have is the one to upload.
The practical limits:
- Clips up to 20 seconds
- Source resolution from 480p up to 2K
- Any aspect ratio, preserved in the output
Run the upscale as the final step, after the edit and the trim are done. Upscaling first means paying for frames that get cut later.
Where Flux Video Upscale runs
Flux Video Upscale sits in the video model picker in the Picsart AI Playground alongside the other video models. Select it, add a clip, set the mode and the upscale factor, then generate.
The Playground also runs Flux 3 for generating video from text, images or an existing clip, which makes the upscaler a natural step straight after generation.
The wider roster of AI video models in Picsart covers generation, editing and extension, and the upscaler is the pass that comes after all of them.

Pick the clip that has been sitting at the wrong resolution, decide whether the frame needs protecting or rebuilding, and run it. Flux Video Upscale is live now in the Picsart AI Playground.
