WinX HD Video Converter Deluxe is a Windows program from Digiarty for converting, compressing, editing and recording video. Digiarty has since renamed it Winxvideo AI. The current release adds AI tools for upscaling video and photos, smoothing motion and cleaning audio to the original converter. The program is paid, with a free trial available, and its separate macOS counterpart is sold as Macxvideo AI.
Its launcher splits the work into modules: Video AI, Image AI, Audio AI, Video Converter, Downloader, Compressor and Recorder. Each one loads files, takes a target or effect and processes them in a batch.
Converting between formats and devices
The converter is the part that carries the WinX HD Video Converter Deluxe name. It reads common containers and codecs such as MP4, MKV, MOV, AVI, WMV, FLV, WebM, VOB and MXF. These include H.264, HEVC and AV1 sources from SD up to 8K. The converter groups output profiles by purpose: general formats, music-only extraction and mobile devices. Other groups cover web upload presets for YouTube, Facebook and Vimeo, plus DVD-compatible VOB in NTSC or PAL. HD containers such as TS, AVCHD and MKV form another group.
Device profiles cover iPhone, iPad, Android phones and tablets, Xbox, PlayStation and Chromecast, plus ProRes for Final Cut Pro and iMovie. A profile fills in its own settings. A codec options panel lets the user change frame rate, resolution and aspect ratio. It also provides controls for audio channels, sample rate and bit rate. A slider trades output quality against conversion speed.
Multi-track MKV handling is a less common feature. Users can merge several videos into one MKV with separate tracks. They can also extract a single video track plus up to two audio tracks from an existing multi-track file. Users choose hardware encoding on NVIDIA, Intel and AMD graphics in Settings. This offloads conversion work from the processor.
Editing toolbox
The program applies edits before conversion, in the same pass. The toolbox includes:
- Cut, trim, split (into equal parts or fixed-length intervals) and merge, with cut segments reorderable
- Crop with freeform or preset ratios such as 16:9, 4:3, 1:1 and letterbox, plus rotate and flip
- Subtitles from SRT or ASS files, either burned into the picture with font and position control or kept as a switchable track
- Brightness, contrast, hue, gamma and saturation adjustments, filter effects and text or image watermarks
- Playback speed from 0.1x to 16x
- Fisheye lens correction, low-pass and high-pass audio denoising, and conversion of side-by-side or top-bottom 3D video to 2D
- GIF creation, frame snapshots and HLS (M3U8) export
AI upscaling and frame interpolation
Video AI enlarges footage by 2x, 3x or 4x, or to a fixed target up to 4K. Four models suit different material. Gen Detail adds texture to skin, hair and fabric. Real Smooth gives cleaner results on animation, line art and low-detail scenes. Anime is tuned for cartoons. Zyxt is designed for low-resolution photorealistic photos. A 1x setting reduces noise, blur and pixelation without changing size, and a colour-preservation slider counters the colour shifts that upscaling can introduce.
Frame interpolation generates in-between frames to raise 24 or 30 fps footage to 60, 120 or higher. It can also produce slow motion at up to five times slower. A scene-change detector stops the model from blending frames across hard cuts. Stabilization offers presets that balance shake removal against the amount of picture cropped, a one-pass or two-pass analysis and fixed, dynamic or custom cropping.
Photo and audio restoration
Image AI applies the same upscaling models to still photos, exporting JPG or PNG at selectable quality and DPI. Face restoration uses Rebuild, Fidelity or GFPGAN models to sharpen faces in old or blurry pictures, and a colorizer adds colour to black-and-white images.
Audio AI separates vocals from instruments to make karaoke tracks or a cappella versions, and suppresses background noise in speech. The user sets how many decibels of noise to remove and can preview the result with and without processing.
Compression for large files
The compressor reduces file size with a single ratio slider, or with manual control over codec, bitrate, resolution, frame rate, GOP length and audio settings. The compressor can compress batches of files together into MP4, MKV or MOV.
Screen recording and downloads
The recorder captures the full desktop or a selected area at up to 60 fps, across multiple monitors, with optional system sound and microphone. It can also record a webcam alone or combine screen and webcam in picture-in-picture, with chroma key to replace the webcam background.
The downloader saves video or audio from a pasted page link, a list of links, playlists or M3U8 streams. It can also save video or audio from a scheduled YouTube live recording and fetch subtitle files. Digiarty does not recommend using it for copy-protected content, and it no longer works on Windows 7.
Trial and full license
The trial version of WinX HD Video Converter Deluxe (Winxvideo AI) includes every module with limits. AI video and image tools give five exports without a watermark. The converter, compressor and editor process up to five minutes of each video. Recordings carry a watermark, and downloads stop below 1080p. A full license removes these limits and adds future updates.
