Summary

An AI video upscaler can turn a shaky 720p gameplay capture into something trailer-ready, but the jump costs you in render time and file size. This calculator estimates the output resolution, bitrate, and file size using a standard bits-per-pixel encoding formula, plus a render time range drawn from public GPU benchmarks for AI upscaling models. Set your source resolution, upscale factor, footage type, and hardware tier, and the numbers update live, no video upload required.

Know What Your AI-Upscaled Capture Will Actually Cost You

You forked a world, recorded the session, and now you want it sharper for a trailer or a devlog. Running an AI video upscaler on that capture gets you there, but it costs you in render time and file size. This tool estimates the output resolution, file size, and render time before you spend a GPU-hour finding out.

Estimates use a standard bits-per-pixel encoding model and published GPU benchmark ranges for standard enhancement models. The highest-quality diffusion-based upscalers can run 10 to 50 times slower than these ranges.

How this works

What the estimator actually calculates

Output resolution

Straight multiplication: source width and height times the scale factor. A 1080p capture at 4x becomes 7680x4320, technically 8K. Whether your hardware can finish that in a reasonable time is the next question.

Bitrate and file size

Uses the bits-per-pixel method encoders have relied on for years: width times height times frame rate times a bits-per-pixel value, from 0.07 for a static menu capture up to 0.14 for combat-heavy footage. More motion needs more bits to stay clean at the same resolution.

Render time range

Built from published GPU benchmarks for standard enhancement models. Diffusion-based upscalers tuned for maximum quality can run 10 to 50 times slower than these numbers, so treat the range as a floor, not a promise.

Common questions

Does this actually upscale my video?
No. It estimates what an AI upscaler will output, resolution, file size, and render time, before you run one. Processing the footage itself still needs a tool like Topaz Video AI, Real-ESRGAN, or a cloud upscaling service.
Where do these numbers come from?
The file size estimate uses the bits-per-pixel method that streaming and encoding guides, including Wowza and StreamShark, have published for years. The render time range is built from public GPU benchmarking data for AI video upscaling, most notably testing from Puget Systems across consumer GPUs.
Why is the render time a range instead of one number?
Because it swings a lot by model choice. Fast enhancement models run close to real time to a few times slower on a high-end GPU. The highest-quality diffusion-based models can run 10 to 50 times slower again. This estimator shows the floor for standard models, not the ceiling for every model.
Why does fast-action footage produce a bigger file?
More motion between frames means the encoder has to keep more information to avoid smearing or blocking. That is a higher bits-per-pixel value, which is why a combat-heavy capture comes out heavier than a menu walkthrough at the same resolution and length.
Why does the estimator stop at 4x?
Past 4x, most AI upscalers stop recovering real detail and start inventing texture that was never in the source. If your capture is 720p, aim for 1080p or 1440p output, not straight to 8K.
Does this only work for AuxWorld captures?
No. The math works for any gameplay or screen capture, from any engine. It matters most here because a forked world often gets recorded fast, at whatever resolution the session happened to run at.
Does AuxWorld upscale video for me?
Not today. AuxWorld generates and runs the worlds; upscaling a capture afterward is a separate step with separate tools. If that changes, it will be stated here directly, not teased as a roadmap item.
Is this free, and is my footage uploaded anywhere?
Yes, it is free, and no video is uploaded. Every calculation runs in your browser from the numbers you type in. The only network call is an anonymous, IP-free ping confirming the tool was used.
