How to Upscale a Video to 4K in 3 Steps

1. Add Your Source Video

Upload an MP4 or MOV file up to 50 MB, or pick a clip you already generated from My Creations. No install, no plugin — it runs in the browser on Windows, Mac and mobile.

2. Choose the Output Resolution

Choose 1080p, 2K or 4K. Sizes below your source are hidden; output dimensions and credits update with your selection.

3. Upscale and Download

Start the job and the enhanced video appears in the history panel when it is ready. Download the MP4 — no watermark, and nothing re-encoded a second time.

AI Video Upscaler FAQs

What does an AI video upscaler actually do?+

It raises the resolution of an existing video while rebuilding the detail that was never captured or was lost to compression. Unlike scaling in an editor, which simply spreads the same pixels over a larger frame, the model predicts plausible fine structure — hair, fabric weave, text edges, skin texture — from what it learned about how real footage looks before and after degradation.

Which files can I upload?+

MP4 and MOV, up to 50 MB per file. We read the real duration and resolution of the file on our servers before the job starts, so a clip that cannot be read is rejected before any credits are spent.

How is the cost calculated?+

By the length of the source video, counted in whole seconds — a partial second at the end is not charged, and every job bills at least one second — at the per-second rate shown next to the cost in the form. Upload your clip first and the panel shows the exact figure before you submit. Failed jobs are refunded automatically.

Should I choose 1080p, 2K or 4K?+

Choose the size your delivery needs. 2K uses the 1440p tier. Sizes below the source are hidden; a matching size remains available for enhancement. Exact dimensions follow the source aspect ratio.

Will upscaling change what happens in my video?+

No. The upscaler is source-preserving: it takes no prompt and cannot add, remove or re-time anything. Duration, framing, cuts and motion come back unchanged; only resolution and clarity differ.

Can I upscale AI-generated videos?+

Yes, and it is one of the most useful cases. Many models cap output at 720p or 1080p. Generate at the model's native resolution, pick the result from My Creations, and upscale it afterwards — usually cheaper than paying a premium tier for a higher-resolution generation.

How long does a job take?+

Time depends on source duration, output size and the provider queue. The job continues after you leave; collect the finished video from your history.

Is there a watermark on the result?+

No. The upscaled MP4 comes back clean and ready to publish, at the same duration and aspect ratio as the file you uploaded.

Do I need to install software?+

No. Everything runs on our servers, so the work does not depend on your machine's GPU. Upload from a browser on Windows, Mac or a phone, close the tab if you like, and collect the result from your history later.

What kind of source gives the best result?+

Footage that is soft or small but otherwise clean. Heavy compression blocking, severe motion blur and extreme low light limit what any model can recover, because the detail is not merely hidden — it was never recorded. Start from the highest-quality master you have rather than a re-exported or re-uploaded copy.
