Visual Enhancer is a portable Windows application for AI-assisted image and video enhancement. Its configurable pipelines combine NVIDIA DLSS 5 Neural Rendering through the Neuroframe Engine, scaling, DLSS Super Resolution, DLSS Ray Reconstruction, RTX Video Super Resolution, AI Upscale for images and video, ReShade, coloring, sharpening, and film grain. Video processing also offers RTX Video HDR, DLSS Frame Generation, FSR Frame Generation, Video Super Resolution, Video Frame Generation, and Upscale (Lightweight) as separate stages.

1. Download the latest release.
2. Extract the complete ZIP archive to a folder.
3. Run Visual Enhancer.exe.

AI models are downloaded separately. Use the Models tab to download them, or enable Upscale or an AI-depth ReShade effect to start downloading the required model automatically. Internet access is needed for downloads; installed models run locally. A fresh package contains no previous outputs or session logs.

The Neural Rendering workspace has separate Image and Video pipelines. Each keeps its own stage order and enabled effects. Drag cards to reorder them and enable only the stages you need; all cards are off by default.

Ray Reconstruction adapts a model designed for ray-traced rendering to imported media using estimated scene guides. It preserves the input dimensions and frame rate. Choose either DLSS Super Resolution or DLSS Ray Reconstruction in a pipeline; enabling one disables the other. RR has a compact enable-only card in Image mode and an expandable Optical Flow Quality control in Video mode, without DLSS mode, preset, or strength controls.

Video-only effects appear as individual cards in the Video pipeline. Stages run from top to bottom; the application checks hardware support, dimensions, frame rates, and HDR compatibility before processing. Choose one frame-generation provider per pipeline: DLSS, FSR, or Video Frame Generation. DLSS and FSR offer Multiplier and Target FPS modes, with fixed targets from 23.976 to 480 FPS; multiplier mode retains the source's fractional frame rate. The Frame Interpolation workspace also lets you choose between DLSS and FSR. ReShade includes a bundled preset, shader and texture search paths, precision and HDR controls, and optional AI depth generation; RTGI shaders are not bundled.

Upscale and Upscale (Lightweight) are separate stages. VisionNext offers automatic or manual tile sizes. The Magnetar models handle tiling automatically. Fixed video targets preserve the whole picture with black bars when aspect ratios differ. Export settings disable codecs that cannot handle the selected dimensions. RazorNext instead offers an automatic or selectable GPU memory budget; lower budgets can reduce GPU memory use at the cost of processing time and additional system memory. RazorNext can require substantial GPU and system memory. Image model sessions can remain loaded briefly between operations and are released after inactivity or when memory is needed; cached image results can also be reused.

SharpNext has been discontinued and is no longer available in the Upscale model selector.

• Comparison: Split, 2-Up, and Output views, zoom, fit-to-view, a shared video timeline, and Focus Preview (Ctrl+Shift+F).
• Compare workspace: compare images and videos with Side-by-Side, Split View, Cycle, and Difference modes. Supported videos use GPU-resident playback at the original source resolution. Save sessions and export comparisons.
• Previews: realtime updates for supported changes, full-resolution image previews, and short video previews from the selected position. Cached results reduce repeated processing.
• Models: manage VisionNext, RazorNext, PeakMagnetar, OptiMagnetar, and TinyMagnetar under Upscale, and MoGe-2 under ReShade. Download, cancel, resume interrupted transfers, or remove models with confirmation. Downloads verify file hashes and retry connection failures. The Models tab shows an animated progress underline during background downloads, including downloads started by enabling an effect.
• Batches: add files or folders, drag and drop, paste clipboard media, track per-file progress, pause or cancel exports, and retry failed items. Show input in Explorer and Show output in Explorer select the corresponding file in File Explorer.
• Export: choose the format, codec, container, quality, output folder, and naming mode. Auto naming uses the _visual_enhancer suffix and adds _2, _3, and so on when needed.
• HDR: preserve or export 10-bit HDR with a compatible pipeline and codec. Place SDR-only effects before HDR conversion.
• Presets: save and restore processing settings, stage order, and enabled effects as JSON.

Image processing applies supported color profiles and EXIF orientation, retains supported metadata, and preserves transparency where the output format allows it. Animated or multipage images use the first frame/page. Video exports retain audio, metadata, and chapters where supported. VP9 defaults to WebM, which also supports AV1. WebM preserves compatible audio, converts other audio to Opus, and converts supported text subtitles to WebVTT.

The application accepts image dimensions up to 32,768 pixels per side, subject to available memory and the limits of the selected effects and file format.

• Windows: Windows 11, 64-bit.
• GPU and driver: NVIDIA GeForce RTX with a compatible NVIDIA driver for DLSS, RTX Video, and NVIDIA Video Effects. Super Resolution and Lightweight Upscale support RTX 20, 30, 40, and 50 series; Neural Rendering availability is checked on the selected GPU. FSR Frame Generation has its own DirectX GPU selection and compatibility checks.
• AI Upscale: a DirectX 12 hardware GPU compatible with DirectML, with enough GPU and system memory for the selected model and output size.
• Ray Reconstruction video: NVIDIA Optical Flow support must be available through the installed NVIDIA driver. Images do not require optical flow.
• Frame generation: DLSS Frame Generation and NVIDIA Video Frame Generation require supported RTX 40 or 50 series hardware. Enable Hardware-accelerated GPU scheduling in Windows for DLSS Frame Generation. FSR Frame Generation uses compatible DirectX 12 hardware and AMD FidelityFX Optical Flow; adapter support is checked before processing.
• Video filtering: a working Vulkan-capable GPU and driver for Vulkan filter stages. NVIDIA, AMD, or Intel can handle this path. FSR Frame Generation uses DirectX 12 for its own processing.

NVIDIA NVENC export requires an encoder supported by the selected RTX GPU. AV1 hardware encoding on NVIDIA requires RTX 40 or 50 series. FSR exports require GPU encoding with H.264, H.265, or AV1 on the selected DirectX adapter; codec support is checked on that GPU. ProRes and FFV1 are not FSR export codecs.

Settings contains interface language, AI Processing GPU (Tensor Cores / NGX) for NVIDIA processing, AI Processing GPU (DirectX 12 / FidelityFX) for FSR Frame Generation, a separate Upscale → GPU selector and AI Inferencing Framework for AI Upscale, Decoding / Encoding Device, Realtime Preview, and Processing Cache. The processing GPU selections are independent of the general video device setting. AI Upscale can use automatic GPU provider selection or DirectML; first-time model preparation can take longer, and compiled models can be reused later. FSR's Auto selection prioritizes a compatible discrete GPU using Windows' high-performance adapter preference. Clean Cache releases reclaimable preview, shader, and processing cache data. Preset import and export are available from the header menu.

Use the processing cards for individual effects and Export Settings for image format, bit depth, video codec, container, quality, and Preserve / Export 10-bit HDR. The Export dialog selects the destination and filename. Saved settings, caches, and downloaded models use Windows per-user storage; replacing the application folder does not reset them. The default output folder is outputs/ beside the executables, and session logs are stored in logs/; these folders are created when the application starts. Temporary processing files use application-managed temporary storage.

The interface supports the following languages, with language changes applied immediately:

VE_CLI.exe uses the same processing engines as the desktop application. Keep Visual Enhancer.exe and VE_CLI.exe at the release folder's root, together with the bundled Qt DLLs, bin/, resources/, and plugin folders.

.\VE_CLI.exe render "photo.png" -o "results\photo.png"
.\VE_CLI.exe reconstruct "photo.png" -o "results\photo-rr.png"
.\VE_CLI.exe reshade "photo.png" --reshade-preset "look.ini" -o "results\photo-reshade.png"
.\VE_CLI.exe upscale "photo.png" --engine visionnext --scale 2 --tile auto -o "results\photo-visionnext.png"
.\VE_CLI.exe upscale "photo.png" --engine peakmagnetar --scale 2 -o "results\photo-peakmagnetar.png"
.\VE_CLI.exe upscale "clip.mp4" --scale 2 -o "results"
.\VE_CLI.exe interpolate "clip.mp4" --fps 60 -o "results"
.\VE_CLI.exe interpolate "clip.mp4" --interpolator fsr3 --fsr-gpu auto --fps 60 --codec hevc -o "results\clip-fsr.mp4"
.\VE_CLI.exe interpolate "clip.mp4" --interpolator fsr3 --multiplier 3 -o "results\clip-fsr-3x.mp4"
.\VE_CLI.exe render "clip.mp4" --preset "pipeline.json" -o "results"

Use --help for options, --recursive for subfolders, --dry-run to inspect a job, and --json --quiet for scripting. Use reconstruct --help for RR options; RR always processes at 1× and does not accept DLSS mode or RR preset options. interpolate defaults to DLSS; select FSR with --interpolator fsr3, then choose either --fps or an integer --multiplier from 2 through 8. --fsr-gpu accepts auto, a DirectX adapter index, or a saved DXGI ID from devices --json, independently of the NVIDIA --gpu option. ReShade accepts --reshade-preset, shader and texture search paths, and depth controls; use reshade --help for details. Presets exported from the application include advanced effect and export settings. Without -o, output goes to outputs/ beside the executables.

For AI image Upscale, select --engine visionnext, --engine razornext, --engine peakmagnetar, --engine optimagnetar, or --engine tinymagnetar. Each accepts --scale 1|2|4|6|8. VisionNext supports --tile auto|256|512. RazorNext uses --memory-budget auto|unlimited|12|8|6 instead of manual tiling. Use --upscale-gpu auto or a saved DirectX adapter ID to select the Upscale GPU independently of NVIDIA processing. Required models download automatically if they are missing. ReShade's AI-depth model is selected with --reshade-depth moge-2-vitb; auto downloads it only when the preset requires depth.
