Visual Enhancer

Visual Enhancer is a portable Windows application for AI-assisted image and video enhancement on NVIDIA RTX GPUs. Its configurable pipelines combine NVIDIA DLSS 5 Neural Rendering through the Neuroframe Engine, scaling, DLSS Super Resolution, RTX Video Super Resolution, coloring, sharpening, and film grain. Video processing also offers RTX Video HDR, DLSS Frame Generation, Video Super Resolution, Video Frame Generation, and Upscale (Lightweight) as separate stages. Arrange the effects, compare previews, and export single files or batches.

Installation

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

Main features

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.

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.

Workflow and preview

• Comparison: Split, 2-Up, and Output views, zoom, fit-to-view, a shared video timeline, and Focus Preview (Ctrl+Shift+F).
• Previews: realtime updates for supported changes, full-resolution image previews, and short video previews from the selected position. Cached results reduce repeated processing.
• Batches: add files or folders, drag and drop, paste clipboard media, track per-file progress, pause or cancel exports, and retry failed items.
• Export: choose the format, codec, container, quality, output folder, and naming mode. Existing files are not silently overwritten.
• 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.

Supported media

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; subtitle preservation depends on the processing path and container.

Requirements

• Windows: Windows 11, 64-bit.
• GPU and driver: NVIDIA GeForce RTX with a current NVIDIA driver for NVIDIA effects. Super Resolution and Lightweight Upscale support RTX 20, 30, 40, and 50 series; Neural Rendering availability is checked on the selected GPU.
• Frame generation: RTX 40 or 50 series. Enable Hardware-accelerated GPU scheduling in Windows for DLSS Frame Generation. NVIDIA DLSS, Video Frame Generation support.
• Video filtering: a working Vulkan-capable GPU and driver. NVIDIA, AMD, or Intel can handle this path; CPU decoding/encoding does not replace the GPU needed for these filters.
• Storage: extract the complete package to a writable folder, with free space for output files and temporary video data.

NVIDIA NVENC export requires an encoder supported by the selected RTX GPU. AV1 hardware encoding requires RTX 40 or 50 series; software AV1 is available through the plain codec option.

Settings

Settings contains interface language, AI Processing GPU, Decoding / Encoding Device, Realtime Preview, and preset import/export. Select the AI GPU separately from the device used for video decoding and encoding.

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. Portable settings, outputs, logs, and temporary files are stored under data/; the default output folder is data/outputs/, and logs are in data/logs/.

Command line

VE_CLI.exe uses the same processing engines as the desktop application. Keep both executables beside the app/ folder.

.\VE_CLI.exe render "photo.png" -o "results\photo.png"
.\VE_CLI.exe upscale "clip.mp4" --scale 2 -o "results"
.\VE_CLI.exe interpolate "clip.mp4" --fps 60 -o "results"
.\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. Presets exported from the application include advanced effect and export settings. Without -o, output goes to data/outputs/.
