Why people keep it installed
Your videos have more to give.
The gap between “it opened” and “that looked incredible” is made of small things — a file that refuses, a subtitle a half-second late, a laptop roaring through a 4K scene. AIX Player brings those controls together and can put the result on a supported television.
PRO
One app. All seven TV families.
Google Cast, Fire TV, Roku, Apple TV, LG webOS, Samsung Tizen and DLNA TVs — AIX Player finds them on your network by itself.
If your TV can't play a file, it converts on the fly using your graphics chip — and your subtitles render right on the TV screen.
Subtitles travel with the video, every time
Real per-brand pairing, never blurry mirroring
60 free casting minutes to try it — unlimited with Pro
The file that wouldn’t open, opens
No separate codec pack to install. Support for most video file types and codecs is built into the app, including MKV, MP4, HEVC and AV1.
Fixes the film, not just plays it
Subtitle a half-second late? Nudge it. Dialogue too quiet under the music? Boost it. Scene too dark to follow? Lift it. All from inside the player.
Your laptop stays quiet and charged
Supported hardware decoding can reduce processor load during 4K playback. The result depends on the file, graphics hardware, driver and power settings.
4K that actually looks like 4K
HDR and 10-bit playback on your PC can preserve smoother gradients. Playback performance depends on the file, graphics support, storage and display.
Copilot+ laptops finally play 4K properly
On a Snapdragon machine most apps run through a translation layer, and video suffers worst. AIX Player is built for that processor directly — so it runs like it should.
No ads. Not one, anywhere
Not on launch, not before a film, not tucked into your library. No ads in either tier.
And everything else it does.
The controls a good player should have, all built in and all a click away — no menus to dig through and nothing extra to install.
Subtitles, fully in your control
Load a supported subtitle file, restyle the text, shift the timing — or run two languages at once with Pro.
Surround sound kept intact
Multi-channel soundtracks stay as they were mixed rather than folded down to stereo.
10-band equaliser with presets
Ready-made curves for film, music and voice, or set every band by hand.
Picture-in-picture and mini player
Float the film in a corner, or keep it running while you browse your library.
Resume, bookmarks and chapters
Every file remembers its place, and you can name the moments worth returning to.
Library with thumbnails and search
Poster grid or detailed list, sorted by name, size, date or type.
Playlists, favourites and folders
Queue an evening, star what you love, and watch the folders you choose.
Speed, repeat and A–B loop
Playback up to 2×, repeat a film or playlist, or loop just the section you choose.
Picture controls that stick
Crop, zoom, rotate and set the aspect — remembered per file.
Plays from anything plugged in
USB drives, memory cards, external disks and pasted links, opened in place.
Supported video, ready to play.
AIX Player supports 83 video file types with broad codec support built in. No separate codec pack or add-on is required for supported files.

Colors the way they were meant to look.
True 4K HDR with over a billion shades of color. HDR10 is tone-mapped to your display, so bright skies and dark corners keep their detail instead of washing out.
AIX Player uses supported graphics acceleration for decoding and tone mapping, with a processor fallback when the format or hardware requires it. Performance depends on the file, graphics driver, storage and display.

x64 and Arm64
Built native for Intel, AMD and Snapdragon PCs.
Most Windows apps were written for Intel chips, so on a Snapdragon machine they run through a translation layer. It works, but every instruction takes a detour — and video is the worst case for it, because a film is thousands of frames that each have to be decoded in time.
AIX Player ships a native build for each: x64 for Intel and AMD machines, and a true Arm64 build for Snapdragon. Decoding can use supported video hardware. When casting on Qualcomm, only H.264 encoding is hardware-assisted; other conversion stages use the processor. Performance and battery use depend on the file and system.

In short
AIX Player decodes HEVC/H.265, AV1, H.264 and VP9 inside the app, and runs natively on Intel, AMD and Snapdragon (Arm64) Windows machines. Decoding uses supported graphics acceleration where available, with a processor fallback.
It casts to Chromecast, Google TV, Android TV, Fire TV, Roku, Apple TV, LG webOS, Samsung Tizen, Sony Bravia, NVIDIA Shield and DLNA televisions. Supported subtitle formats are rendered onto the picture before it leaves the PC, so the television does not need to read the subtitle file itself — external files included.

Safe on your PC
Installing a video player should not be a risk.
Most trouble with video software starts with where it came from — a download site, a bundled extra, something asking for an account it does not need. None of that applies here.
Only from the Microsoft Store
Every release is reviewed and signed by Microsoft before it reaches you. There is no installer to find on a download site, nothing bundled alongside it and nothing to untick during setup.
Install from Microsoft Store
Get AIX from its official Microsoft Store listing.
No sign-in for local files
Open a local file without creating an account. To play from Jellyfin, Emby or Plex, sign in to your server.
Your local library stays on your PC
Your local library database and viewing history stay on your PC. Network and media-server features contact the computers and servers you select; Plex sign-in also contacts Plex. Media servers can record playback activity under their own policies.
No tracking, no ads
No adverts anywhere in the app, in either tier, and no behavioural tracking following you around your own library. Anonymous diagnostics — crash and casting-failure reports, never what you watch — can be switched off at any time in Settings › About.
Kept up to date
Fixes and new features arrive automatically through the Store, so you are never running a stale build you forgot to update.

Good to know
Questions, answered.
The things people ask most often, before and after installing.
Is AIX Player safe to install?
Yes. AIX Player is published by Ace Thought Technologies through its official Microsoft Store listing, so there is no download-site installer, no bundled extras and nothing to untick during setup. You need no account to play your own files, there are no ads, your watch history is not kept on our servers, and diagnostics are optional. The privacy policy has the details.
Does it play MKV files on Windows 11?
Yes, straight away. Open an MKV with AIX Player and it plays, with every audio and subtitle track inside it ready to switch between. That includes 4K and 10-bit MKV files, with HEVC, AV1 and H.264 video decoded inside the app, so there is no codec pack to install. HDR MKV files play too; HDR has a separate free allowance, then AIX Pro. MP4, AVI, MOV, TS, M2TS, WebM, FLV, WMV and the rest of the 81 file types AIX Player registers work the same way.
Do I need anything extra to play HEVC / H.265?
No. AIX Player includes HEVC and AV1 decoders, so no separate Windows codec pack is required. Supported graphics acceleration can reduce processor load for 4K playback, with a processor fallback where required.
More details: Do I need anything extra to play HEVC / H.265?
Why is my video playing with sound but no picture, or showing a black screen?
Usually your PC cannot decode the picture half of the file. The video is often HEVC (H.265) or AV1, and many Windows PCs have no decoder for those, so you hear the sound over a black screen or get an error. AIX Player decodes HEVC, AV1 and the other common codecs inside the app, so the picture and the sound arrive together. If a file is still black in AIX Player, turn off Settings → Video → Hardware decode and update your graphics driver.
More details: Why is my video playing with sound but no picture, or showing a black screen?
Why is there no sound on my MKV file in Windows 11?
Often the soundtrack is a surround format the player you tried cannot decode. Films copied from discs usually carry Dolby Digital (AC-3), DTS or TrueHD sound. AIX Player decodes all of these inside the app, so here the soundtrack format is not the cause. If an MKV is silent in AIX Player, check the volume and mute, switch the audio track from the audio menu (some files start on a commentary or another language), and check the output under Settings → Audio → Audio device.
More details: Why is there no sound on my MKV file in Windows 11?
How do I make AIX Player the default video player?
Right-click a video, choose Open with, then Choose another app. Select AIX Player and choose Always (on Windows 10, tick Always use this app). From then on every file of that type opens in it. Repeat once for each file type you use, or set them all in Windows Settings → Apps → Default apps. There is no button for this inside the app: Windows asks you to make the choice yourself.
More details: How do I make AIX Player the default video player?
I changed PC — how do I get my purchase back?
Open Upgrade to Pro and select Restore. Your Pro unlock is tied to your Microsoft Store account, so it comes back on a new PC or after reinstalling. Sign in to the Microsoft Store with the account you bought it with. If it still does not appear, contact us; we reply by email.
