Every video. Every screen.

Playback is free and unlimited. Casting is free for a one-off 60 minutes. Every video you play on your PC is free forever — 4K, HDR, 10-bit, every format, no ads, no trial. Casting videos to your TV is the premium part: you get 60 minutes in total — once, not per session — to try it properly, and Pro lifts the limit for unlimited casting to every TV you own. We would rather tell you that here than have you discover it mid-film.

Yes. It comes from the Microsoft Store, so the package is reviewed by Microsoft, signed and sandboxed. No download-site installer, no bundled extras, nothing to untick during setup.

No. Install it from the Store, open a video, and it plays. Nothing to set up first.

For two things you have probably already hit. Files that simply will not open — an MKV, a film copied from a disc — and getting them onto the television without converting anything or losing the subtitles on the way. If neither has ever bothered you, you may genuinely not need this.

Windows 11, or Windows 10 version 2004 (build 19041) or later, 64-bit. There are versions made for Intel, AMD and Snapdragon machines alike, so a Copilot+ laptop runs it directly rather than through a translation layer. Any graphics card from the last few years handles 4K HDR comfortably, and older machines still play everything.

Not for your own files. Anything on your PC or an attached drive plays completely offline. Casting needs your PC and TV on the same home network, but the video travels straight to the television rather than out over the internet. Only a pasted stream URL needs a live connection.

No — usually the opposite. Decoding every frame on your PC’s main processor is what makes fans roar and batteries drain. AIX Player passes that work to your graphics card instead, which is built for it — so your machine stays free for whatever else you are doing.

17 languages. The interface follows whichever language Windows is already set to. Subtitle and audio tracks are separate — those come from the file you are watching, and you can switch freely.

Usually yes, if it downloads in order. A partly complete file will play up to the point it has reached. Torrents that download in pieces often will not, because the beginning may not be there yet — wait for it to finish and try again.

Nine times out of ten it is incomplete, not corrupt. An interrupted download or a copy that failed part-way leaves a file that looks whole but is not. AIX Player will play as much as exists, which is a quick way to tell: if it stops at the same point every time, that is where the file ends.

Yes, straight away. That includes 4K HDR and 10-bit MKV, with every audio and subtitle track inside available to switch between. MP4, AVI, MOV, TS, M2TS, WebM, FLV, WMV and 76 more work the same way.

No. Everything AIX Player needs to open your files is already inside the app. Many PCs are missing what Windows needs for HEVC (H.265) and AV1 — AIX Player brings its own decoders, so it does not matter. Big 4K files stay smooth because your graphics card does the work.

Your PC can read the sound half but not the picture half. The video is usually HEVC (H.265) or AV1, and Windows has no decoder for those on many machines — so you get audio and a black screen, or an error about the file not playing. AIX Player brings its own, so the picture and the sound arrive together.

It has a cinema-style surround soundtrack your PC cannot read. Films copied from discs usually keep the full surround mix from the cinema, and most computers have no way to play it — so you get picture and silence. AIX Player plays it, and keeps all the surround channels rather than squashing them into plain stereo. Nothing to install.

Try it from another folder first. Practically every kind of video file is supported, so this is rare — a file that plays nowhere is usually damaged or only partly downloaded. Genuinely stuck? Send us the file details and we will look into it.

It will play here. AV1 is a newer kind of video file, and only recent computers can handle it on their own. AIX Player brings what it needs, and on newer machines it lets the graphics card take over so playback stays light.

Yes. TS, M2TS and MTS open directly, with chapter marks and the full surround soundtrack intact. These files usually pair an advanced video track with a studio surround mix — both are handled.

It is your graphics software, not the file. Your graphics card is stumbling on that one type of video. AIX Player quietly switches to a different way of playing it so the colours come back — and updating your graphics drivers fixes the root cause.

Modern Windows dropped what those older files need. AVI and the video inside it date from the 1990s, and Windows no longer includes the pieces to open several of them. AIX Player carries them inside the app, so a file from 2004 opens just as easily as a 4K one — and nothing is changed on your PC.

It will open here, with nothing from Apple installed. MOV is what iPhones and most cameras record in, and Windows has always been awkward with it. Plenty of guides still tell you to install QuickTime — you should not, it has been discontinued for years. AIX Player reads MOV directly, including HDR and slow-motion recordings from recent iPhones.

Yes. Nothing to convert first and no renaming .mkv to .mp4 to trick the TV — pick the file, pick your TV, press cast. If your TV genuinely cannot handle a file, AIX Player converts it while it plays, so the film still starts straight away.

Because they never leave your PC. Most casting sends the television the video file alone. AIX Player draws the subtitles into the picture before it travels, so what arrives already has them — external .srt files included, in the size and style you chose.

Your Wi-Fi is the bottleneck. A wired PC, or a spot closer to the router, fixes most of it. Very large 4K files ask a lot of a weak network — and if your TV cannot handle a file as it is, AIX Player quietly converts it while it plays so you never see an error.

It is almost always the network. Roku sets and sticks appear on their own, so check that your PC and TV are on the same Wi-Fi — guest and split-band networks keep them apart — and that the Roku is awake. Roku is also the one device that needs a piece added to it: our free AIX Casting Receiver channel, added once from your Roku account with the code PG26GTJ. AIX Player hands you the link if it is missing.

Your TV could not play the soundtrack. It is usually the cinema surround mix that comes with films copied from discs, and most televisions cannot handle it. AIX Player converts it as it goes; if the film has more than one soundtrack, switching to a plain stereo one also fixes it instantly.

Yes — even the ones your TV cannot read. Televisions only understand a short list of video types, so a file outside that list is where casting usually breaks down. AIX Player checks what your TV can take, and where a file falls outside it, converts just that part on the fly while the film plays. Your original file is never touched and nothing is saved to disk.

No — and usually nothing is converted at all. AIX Player only changes the part your TV genuinely cannot read, which is very often just the soundtrack, leaving the picture untouched at full quality. When the video itself does need converting, it is done on your graphics card in real time, so 4K and HDR are preserved rather than downgraded to get it moving.

Because the conversion happens as the film plays. Other approaches make you convert the whole file first and wait, sometimes for hours. AIX Player converts frame by frame while streaming, using the dedicated video hardware in your graphics card, so the film appears on the TV within seconds no matter how large it is.

You probably do not need one. If your television is a Samsung, LG or Sony smart TV, AIX Player connects straight to it using what is already inside the set. The same is true of Fire TV, Roku, Apple TV and Android TV boxes you may already own — and for older televisions there is usually a route in as well. Nothing to buy and nothing to plug in.

Your PC is using the wrong part of itself to do the work. The main processor is grinding through every frame while the graphics card — the part actually built for video — sits idle. AIX Player gives the job to the graphics card, so even huge 4K files run smoothly, fans stay quiet and a laptop keeps its charge.

The film holds more brightness than your screen can show. HDR films are made for very bright displays, so on an ordinary monitor the extremes get cut off and everything looks flat. AIX Player reshapes the picture to fit your screen, so bright areas and shadows both keep their detail. You can fine-tune brightness and contrast too.

Switch the audio track. Films often carry several and the first is not always the right one — open the audio menu and pick another. Also worth checking Windows is playing to the device you expect: headphones, TV or speakers.

Yes — three controls help. The 10-band equaliser is free for everyone. Dialogue boost, which lifts speech over music and effects, and loudness levelling, which evens out the loud scenes for late-night viewing, are part of AIX Player Pro.

Nudge the audio delay. Shift the sound earlier or later while the film keeps playing, until lips and words agree. The offset stays with that file, so it is a one-time fix. Subtitles have their own separate timing control.

It is being shown at the wrong shape. Older recordings and phone clips sometimes carry the wrong information about how wide they should be. Change the shape setting to fit the frame properly, or zoom in to fill the screen. Clips filmed sideways can be rotated too.

Yes. Surround soundtracks keep all their channels rather than being squashed into plain stereo, so a film sounds the way it did in the cinema. It matters for casting too — many televisions cannot play these soundtracks, so AIX Player quietly converts them on the way.

Check the playback speed first. It stays wherever you last left it, so one tap returns it to normal. If that is not it, footage shot on a phone or camera at a very high number of frames per second can look odd on a screen running at a different rate.

The black bars are part of the picture itself. Some copies have them permanently built in, so going full screen just makes the bars bigger too. Zoom in to fill the screen properly, and AIX Player remembers that setting for the file.

Usually the drive it is stored on. A slow external drive or a failing disk cannot feed the film fast enough, even when the rest of your PC is coping easily. Copy the file onto your PC to test — if it plays smoothly there, the drive was the problem.

Yes, with ten bands and ready-made presets. Start from a curve made for films, music or voice, or set it by hand. The trick most people miss is to cut what is in the way rather than boost what is not — easing off the deepest bands does more for clarity than raising anything. Whatever you set is remembered for that file.

Yes, at full quality. Capturing from the player saves the frame at the film’s own quality, rather than the shrunken version your monitor is showing — noticeably sharper with 4K films.

One key, or one tap in the subtitle menu. Subtitles toggle without pausing the film, and the track you pick is remembered for that file so you do not set it again next time.

Yes — size, colour, outline and a backing box. Set them large enough for how far you sit from the screen. If you cast to a television afterwards, that styling travels with the picture, so size for the room rather than the desk.

A film often includes several, and the first is not always yours. Open the subtitle list and pick the right one. If one option only shows a handful of lines, that is the kind meant just for foreign dialogue — working as intended, not broken.

Yes, vertically. Useful when lines sit over on-screen text or fall into the black bar at the bottom. If subtitles ever seem to vanish entirely, position pushed too far is a common cause — resetting the styling brings them back.

From any subtitle site, then load the file directly. You do not need to rename it to match the video. Open the subtitle menu, point AIX Player at the file wherever it saved, and it loads immediately. SRT, ASS, VTT and disc-style image subtitles all work.

Not into the file, but they are burned in when casting. Your original file is never modified. When you cast, subtitles are rendered onto the picture before it leaves the PC — which is exactly why they reach televisions that cannot read subtitle files at all.

Load the file from the subtitle menu. No need to rename anything to match the video. Once it is on, you can restyle the text size, colour, outline and background box to suit the room you are watching in.

Yes. Shift them earlier or later while the film keeps playing, until the words land with the lips. The offset sticks for that file, so you only do it once. Audio can be nudged the same way if the sound is what drifts.

The subtitle file was saved for a different alphabet. That is why accented letters and non-English characters turn into boxes and question marks. AIX Player understands the usual ones, so files that looked broken elsewhere normally read correctly here — and another subtitle file for the same film will almost always work.

Yes — every file, individually. Close one mid-film, open it a week later and it picks up where you left off. Your library shows how far through each one you are, and you can drop named bookmarks on moments worth returning to.

Yes. Picture-in-picture floats the video in a corner over whatever else you are doing, and a mini player keeps it going while you browse the rest of your library. Playback speed goes to 2× for long material.

Yes, directly. External drives, USB sticks, memory cards and phones plugged in over USB all open in place, with nothing to copy to the PC first — and you can cast straight from them too. A very slow or old drive can make big 4K films stutter, and copying that one file onto your PC solves it.

Right-click a video, Open with, Choose another app. Pick AIX Player and tick Always use this app. From then on every video of that type opens in it. Repeat once for each file type you keep — or set them all in Windows Settings under Default apps.

Yes — open the folder and play through it. Everything in the folder queues up in order, and you can shuffle or repeat the run. For a fixed running order you want to keep, build a playlist instead and it stays saved.

Both. Repeat plays a file or a whole playlist over again, and A–B repeat loops just the section between two points you set — useful for practising a passage or studying a technique without scrubbing back each time.

Point AIX Player at the folders they live in. It builds a library with thumbnails, durations and how far through each file you are, shown as a poster grid or a detailed list. Nothing is moved or renamed on disk — your folders stay exactly as they are.

Yes — grid or list, whichever you prefer. Every file gets a thumbnail, its length and a progress bar for what you have already watched. Switch to a list when you want file sizes and formats visible instead.

Search across the whole library, then sort. Sort by name, size, date added or file type, ascending or descending. Past a few hundred files this is far faster than opening folders one at a time.

Yes, and act on all of them together. Multi-select lets you favourite a batch, add them to a playlist or remove them in one action rather than repeating yourself for each file.

Yes — folders preview in place. Peek inside to see what is there, then drill into subfolders without losing your place. Useful when a drive has dozens of similarly named directories.

On its details page, all together. Quality, video type, length and file size on one screen — the quickest way to check whether a file really is the 4K version you thought you downloaded.

Removing is there; renaming happens in Windows. You can remove files from the library or from disk, and multi-select makes clearing out a folder quick. Renaming stays with File Explorer, so the player never changes your filenames behind your back.

Yes, with a version built for those machines. Most apps on a Snapdragon laptop run through a translation layer, which slows them down and drains the battery. AIX Player has a version made for that processor directly, so nothing is being translated — 4K HDR stays smooth, the laptop stays cool and the battery lasts.

Sign in to the Store with the same account. Your purchase travels with the account, not the machine — install AIX Player and it is restored. If it does not appear, get in touch and we will sort it out.

They are in the works. Windows is the only released version today. The others are in development and we have not set a date for them — they will use the same playback engine and the same casting.
