PixelForge AI / PixForge

A cinematic, local-first video and image upscaling workflow for creators who need sharper exports, cleaner restores, and faster quality checks before a long render. Output keeps your source aspect ratio — enhancer, not a Shorts reframer.

Real app surfaces

PixelForge ships as a Windows desktop app with a documented GUI — these captures are from the live product page and enhancer interface, not stock upscaling demos.

Desktop app PixelForge AI

GPU upscaling with engine choice and batch queue

SPAN DirectML, Real-ESRGAN, RealSR, Waifu2x, Real-CUGAN, and SRMD run locally with progress feedback — the same packaged app linked from knightlogics.com/pixelforge-ai, not a cloud-only upscaler subscription.

  • Windows desktop build with documented install path
  • Local GPU engines with compare-before-you-commit previews
  • See VideoForge for the ranked-video sibling app

Local

Your footage stays on your own machine instead of being uploaded to a hosted render service.

Compare

Draggable before/after preview samples multiple frames through your clip so you are not stuck judging quality from a black intro frame.

ETA

Stage-by-stage processing estimates highlight the slowest parts of the pipeline up front.

Credits

Free install with 8 server-backed trial credits. Packs are $5 / 12, $10 / 30, or $20 / 72 through protected Stripe Checkout — no payment secrets in the app binary.

Built For Real Video Cleanup

Native-safe AI model and scale combinations, benchmarked defaults, and advanced controls that stay out of the way until you need them.

Six Local AI Enhancement Engines

Current SPAN DirectML models join Real-ESRGAN, RealSR, Waifu2x, Real-CUGAN, and SRMD. Refined presets select by content, while a hardware-gated NVIDIA RTX VSR Ultra profile appears only after compatible GPU, driver, VRAM, and real-inference checks pass.

RIFE Smooth 60 FPS

Choose Keep source or Smooth 60 FPS independently from enhancement. RIFE 4.25 is recommended, 4.26 is optional, and sources already near 60 FPS are preserved without an unnecessary interpolation pass.

Runtime Awareness

ETA guidance uses hardware detection and stage timing profiles so you can test with shorter clips before long exports.

Direct Auto-Updates

The updater checks GitHub Releases, downloads the latest Windows build, and reduces manual maintenance after setup.

Workflow Profiles

Fast drafts when you need answers. Higher detail when you are ready.

PixelForge AI is structured around practical production behavior: run a quick check first, inspect a compare view, then move into a cleaner pass once the settings are proven.

Fast Preview The quickest test path for checking a crop before committing to a long job.
Balanced Workflow The best overall starting point: benchmarked content-aware defaults with Same resolution, 1080p, 1440p, 4K, or 8K target output.
Max Detail The highest-detail content model and conservative post-processing for a final delivery pass; expect substantially longer processing.
NVIDIA RTX The fastest compatible SDR path. It is hardware-specific, not a universal replacement for Max Detail or the HDR/10-bit precision path.

Upscaling Engines

  • Real-ESRGAN — general footage and restoration
  • RealSR (GPU) — photo-realistic upscaling with DF2K and DF2K_JPEG models
  • Waifu2x (GPU) — anime and illustration with cunet and upconv_7 models
  • SPAN DirectML — current fast photo and animation models
  • Real-CUGAN — refined anime and game detail
  • SRMD — adjustable denoise for old or noisy sources
  • NVIDIA RTX VSR Ultra — optional sidecar shown only on a verified compatible RTX system

Interpolation & Advanced Controls

  • RIFE GPU — one-click Smooth 60 FPS via ncnn-vulkan (4.25 recommended; 4.26 optional)
  • minterpolate CPU — fallback for non-Vulkan systems
  • Three cached source-frame crop previews with progress and cancellation
  • H.264, HEVC 10-bit, AV1 10-bit, ProRes 422 HQ, image sequences, and NVENC
  • High-bit sources stay RGB48 through FP32 DirectML inference and feed the final 10-bit encoder without an 8-bit frame checkpoint
  • Automatic quality guard corrects interlaced sources, routes HDR/10-bit video away from 8-bit AI engines, and warns before enlargement beyond a credible 4x recovery range

How The App Works

A straightforward desktop workflow built around reducing wasted processing time.

01

Select input and output

Load a video or still image, choose where the export should land, and define a clip range when you want a quick validation pass on footage.

02

Pick a profile

Choose a speed profile and a content profile so the app sets sane defaults before you go deeper into advanced controls.

03

Preview and estimate

Inspect three real source-frame numbers, choose a fast detail crop or full frame, drag the cyan before/after separator, and cancel or reuse cached preview work.

04

Run the final pass

Launch the full job once settings are proven. DirectML jobs stream decoded frames through AI into the single final encode with one frame resident at a time. Directory-only NCNN and RIFE jobs use disk preflight, bounded batches, checkpoints, and resume.

Packaging

Packaged As A Standalone Windows App

The universal Windows package includes six enhancement engines, RIFE, FFmpeg, and their model assets. Compatible RTX systems receive an automatic first-run setup offer, and a larger NVIDIA edition includes the verified VSR sidecar in the download. The updater stages releases through AppData and relaunches cleanly.

System requirement

A DirectML- or Vulkan-capable Windows GPU is recommended. The NVIDIA profile is only shown on compatible RTX hardware; NVENC is used when available for H.264, HEVC, and AV1 delivery, with software fallbacks.

What it is not

PixelForge AI upscales and optionally resizes in place. It does not crop landscape into vertical Shorts, reframe for TikTok, or force every export to 9:16 unless you explicitly enable final scaling with those dimensions.

PixelForge / PixForge FAQ

Is PixelForge Windows-only?

Yes. PixelForge AI targets Windows 10/11 with a Vulkan-capable GPU. macOS and Linux builds are not offered on this page.

How do credits and purchases work?

Download is free. New devices get trial credits. Additional packs are purchased in-app through Stripe Checkout on the Knight Account API — same billing stack as other Knight Logics desktop apps.

Is PixForge AI the same as PixelForge AI?

Yes. People often search pixforge ai, pixel forge ai, or pix forge — they all refer to this Windows local upscaler.

Is PixelForge a YouTube Shorts converter?

No. It upscales and restores while preserving source aspect ratio. It is not a vertical Shorts reframer.

Can Knight Logics build a custom Windows app like this?

Yes. PixelForge is proof we ship real desktop software. See custom desktop applications or request a consultation.

Liked the software? Need customers, not another app?

PixelForge is Software Lab proof. The client offer is getting Tampa Bay businesses on Google: Launch Kit $299, GBP from $497, then the system that keeps the phone ringing.
