Picture & sound

Sounds like the cinema.
Looks like the future.

Deeper blacks. Highlights that gleam. Sound that fills every corner of the room. mtivi plays your source at the very ceiling of what your screen and speakers can do — and shows you, right on the picture, exactly what’s live.

Great content,
flattened on the way in.

You pay for 4K. You bought the screen. Then the picture lands washed-out, the motion judders, and half the time the sound just… disappears.

mtivi refuses to flatten it. It reads what the stream really is and plays it at full strength — no settings, no compromise.

HDR ignored. Brilliant footage rendered dull and gray because the player never switched the screen into its high-dynamic-range mode.

Stutter and judder. 50 and 60fps motion smeared because the picture was forced to a refresh rate it was never filmed for.

Silent video. A rich surround soundtrack that plays as nothing at all because the device "doesn't have the license."

"Unsupported format." A dead stop on a stream a player simply refused to decode.

4K · HDR

Every pixel.
Every nit of light.

mtivi plays full 4K Ultra HD on capable devices, then detects HDR automatically and lights up your screen’s brightest, richest mode — with an on-screen badge confirming exactly which format is live.

  • 4K / Ultra HD playback — full-resolution UHD streams on capable screens.
  • HDR10, HLG & Dolby Vision — detected automatically, with the type shown on screen so you know you've got the brighter, deeper picture.
  • The badge that proves it — no guessing whether HDR kicked in. mtivi tells you.

Sport that
never smears.

High-frame-rate footage is meant to be liquid-smooth — until a player crams it into the wrong refresh rate and the panning judders. Auto Frame Rate quietly matches your TV to the content, frame for frame.

  • High frame rate, played in full — 50, 60fps and beyond render the way they were shot.
  • Auto Frame Rate — flip on one setting and your TV's refresh rate locks to the content for judder-free motion.
  • Video Start Speed — choose Fastest, Balanced, or Smoothest startup to trade a quick start against extra buffering.

Surround that
refuses to go silent.

The dialogue sits forward. The score swells behind it. The room fills, corner to corner. mtivi carries rich Dolby and DTS soundtracks itself — so a track that would play as silent video on the bare hardware lands in full, multichannel sound instead.

5.1 surround Dolby Digital Plus · DTS · TrueHD

Dolby & surround, always

Dolby Digital and Digital Plus, DTS and TrueHD land in full multichannel sound — the kind that puts you inside the scene. Even on hardware that would otherwise hand you a silent stream.

Clean, clear, every time

Soundtracks come through crisp and in sync across every device and stream — no muffled dialogue, no dropouts, no staring at moving pictures wondering where the sound went.

Audio balance · L / R

Shift the sound toward the left or right channel — perfect for headphones, an uneven speaker setup, or if you simply hear better in one ear.

Plays virtually anything

No "unsupported format."
Just play.

Broad codec and container support across both Xtream and M3U / M3U8 playlists — and when a device’s built-in decoders choke on a stream, mtivi falls back to software and just plays it. The dead-end error other players throw simply doesn’t happen here.

H.264 HEVC AV1 VP9 MPEG-2 AAC AC-3 E-AC-3 TS MKV MP4 …and more

Decoder modes built in. Auto (hardware preferred), Hardware only, or Prefer software — so a stubborn stream that won't play on the chip can fall back and just work.

Dial it in

Hands-off when
you want it. Hands-on
when you don't.

Smooth adaptive streaming handles the picture for you — or take the wheel. Pick a fixed quality, set different caps for Wi-Fi and Ethernet, and run a quick built-in speed test that recommends a stable cap for your connection.

  • Adaptive + manual quality — Auto, or lock 4K / 1080p / 720p / 480p / 240p.
  • Per-network caps + speed test — separate limits for Wi-Fi and Ethernet, with a one-tap test that suggests a stable cap.
  • Diagnostics overlay — source, decoder, resolution, codecs, bitrate and dropped frames, for when you want to see under the hood.

The mtivi difference

Flagship picture.
Zero tinkering.

Bring the source you already have. mtivi makes it look and sound like the equipment you paid for — and it’s all in the free tier.

It just looks right

HDR detected, the right mode switched on, the badge confirming it. You never dig through menus to "turn on" the picture you already paid for.

It never goes silent

Dolby, DTS and TrueHD soundtracks play even on devices missing those licenses — so a rich stream never collapses into silent video.

It just plays

Broad codec support with automatic software fallback means the "unsupported format" dead-end other players hit simply doesn't appear.

Smooth, judder-free motion

Auto Frame Rate locks your TV to the content so fast-paced footage stays liquid — no smearing on the pans.

Tuned to your room

Per-network quality caps, a built-in speed test, and left/right audio balance — fine adjustments that meet your gear and your space.

All of it, free

4K, HDR, Dolby Vision, surround sound, every format, every control — the entire picture-and-sound stack is in the free tier.

Built for 4K HDR

See it the way
it was meant to look.
