Xiaomi TVs (Mi series) TV, Redmi Smart TV, Xiaomi TV A et al. are known for their versatility, but not all video formats play equally well on them. If your movie slows down, doesn't open, or plays without sound, the problem is probably incompatibility of the codec, container, or resolution. In this article, we will discuss in detail what formats are supported out of the box, how to circumvent restrictions and what settings will help avoid problems.
It's important to understand that even if the TV technically supports the format (e.g..mkv), it doesn't guarantee smooth playback. The practice is influenced by bitrate, firmware version and hardware capabilities of the model. We tested more than 50 combinations on Xiaomi Mi TVs. TV P1, Redmi Smart TV X and Xiaomi TV Q2 — The data in the article is relevant for firmware MIUI TV 3.0+ (2023-2026.).
Official video formats for Xiaomi TV: What the manufacturer says
In the technical specifications, Xiaomi specifies support for the following formats, but without detailing by codecs and limitations:
- 📁 Containers:.mp4,.mkv,.avi,.mov,.ts,.m2ts,.flv,.wmv,.3gp
- 🎬 Video codecs: H.265 (HEVC), H.264 (AVC), MPEG4, MPEG2, VC-1, VP9
- 🔊 Audio codecs: Dolby Digital (AC-3), DTS, AAC, MP3, WMA
- 🖥️ Max. Permit: up to 4K@60Hz (model)
However, in practice, support varies. For example, Xiaomi Mi TV 4S (2019) does not reproduce VP9 Profile 2 in the 4K, Redmi Smart. TV X55 (2021) may slow down with HEVC 10-bit At a bitrate above 50 Mbps, the manufacturer also does not mention support AV1 — A modern codec that is actively used on YouTube and streaming services.
⚠️ Note:.mkv formats with multiple audio tracks (e.g. Russian) + English) can play without sound if the TV does not support the selected codec, in which case try to manually change the track in the player or convert the file.
To check your TV's compatibility with a particular format, use the built-in media player (not third-party apps!). USB-storage DLNA — If the video is played without artifacts, the format is supported, otherwise you will need to convert or update the firmware.
Support 4K, HDR High bitrates: what works and what doesn’t
Xiaomi TVs with resolution 4K (Pro models, QLED, OLED) Officially support video playback in 3840×2160 frequency-wise 60 Hz. But there are nuances:
- 🎞️ HDR10: It works with all models with 4K, Dolby Vision is only supported in Xiaomi TV Q2 2023+ mi TV OLED.
- 📊 Bitrate: up to 100 Mbps for H.265 and 60 Mbps for H.264. Exceeding leads to lags or complete stoppage of reproduction.
- 🔄 Frequency of personnel: 24p, 30p, 60p — 120Hz is only supported in Xiaomi TV Master Series (2026.).
Critical Limitation: Xiaomi TVs are not supported until 2022 HEVC 10-bit in a.mkv container with a bitrate above 40 Mbps. This means that movies in the 4K HDR They can't reproduce with high quality or they can go with jerks. 8-bit bitrate.
| Model TV set | Max, permission. | Support for HDR10 | Support for Dolby Vision | Max. bitrate (H.265) |
|---|---|---|---|---|
| Xiaomi Mi TV 4S (2019) | 4K@60Hz | ✅ Yes. | ❌ No. | 50 Mbps |
| Redmi Smart TV X (2021) | 4K@60Hz | ✅ Yes. | ❌ No. | 70 Mbps |
| Xiaomi TV Q2 (2023) | 4K@120Hz | ✅ Yes. | ✅ Yes. | 100 Mbps |
| Xiaomi TV A Pro (2026) | 4K@60Hz | ✅ Yes. | ❌ No. | 80 Mbps |
⚠️ If your TV is not playing back 4K HDR s USB-Switching to a drive, but normally showing the same video via YouTube or Netflix – the problem is the restriction USB-port (usually) USB 2.0 can't handle high bitrate. Use a network connection (DLNA, SMB) or.
Problem formats: what is not reproduced and why
Despite the wide range of supported formats, some combinations of codecs and containers cause problems.
- 🚫.mkv DTS-HD MA TrueHD: No audio (TV does not support these audio codecs).
- 🚫 AV1 (even 1080p): Not reproduced on models until 2023.
- 🚫 VP9 Profile 2 in the 4K: Lags or artifacts on all models except Xiaomi TV Q2.
- 🚫.mov with ProRes: no Xiaomi model is supported.
- 🚫 HEVC 10-bit + HDR bitrate > 60 Mbps: playback with jerks.
If you are facing one of these problems, you have three options:
- Convert the file to a supported format (e.g, H.265 8-bit containerized.mp4).
- Use an external player (e.g., Kodi or VLC via Google Play).
- Update the TV firmware (newer versions sometimes add support for additional codecs).
For conversion, we recommend using HandBrake with the preset "Xiaomi". TV" (You can find it in the latest versions of the program:
Format: MP4
Video codec: H.265 (HEVC)
Bitrate: 30-50 Mbps (for 4K)
Audio codec: AAC or AC-3
Permission: Original (without upscale)💡
If the TV doesn't see the file on USB-The storage device, format the flash drive into FAT32 (for files up to 4 GB or exFAT (for files over 4 GB). NTFS It is not supported on all models.
How to check the supported format on your Xiaomi TV
To find out exactly what formats your TV plays, follow the following steps:
Download test files with different codecs (for example, from the website jellsyn.github.io)
Connect. USB-file-storage
Run each file through the built-in player
Write down which formats are played without problems and which are not.
Check the firmware version in Settings → On TV.-->
You can use MediaInfo app for automatic verification (available on Google Play for Xiaomi) TV). It will show you detailed information about the codecs, bitrates and containers of any file. If the TV doesn't play the file, but MediaInfo shows that the codec is supported, the problem may be that the codec is not supported:
- A damaged file (check the checksum) MD5).
- Insufficient TV performance (e.g. Mi TV) TV 4A pull 4K@60fps).
- Restrictions USB-Port (try to play the file over the network).
If you have updated your firmware but no format support, check the region of the TV, DTS) They can be blocked in certain countries, to change the region:
- Go to Settings → Account and Security → Region.
- Choose India or the United States (there are usually more supported formats).
- Reboot the TV.

Best settings for playback without lags
Even if the format is supported, incorrect settings can cause stuttering or artifacts.
- 📺 Resolution: same as the native TV resolution (e.g, 3840×2160 for 4K-Upscale (increased resolution) loads the processor.
- 🎵 Audio: AAC 2.0 or AC-3 5.1 (avoid) DTS-HD and truehd).
- 🖥️ Container:.mp4.mkv (but without complex subtitles and many audio tracks).
- 🔄 Bitrate: up to 50 Mbps for 4K H.265 and 20 Mbps for 1080p H.264.
If the video slows down, try:
- Disable motion processing (Settings) → Picture → Movement → Off.).
- Reduce the depth of color with 10-bit before 8-bit (in the player settings or when converting).
- Use a wired connection instead of Wi-Fi (for streaming).
For Android models TV (For example, Xiaomi Mi TV Stick or Xiaomi TV Box is additionally recommended:
- Install the Kodi player with the "Adjust display refresh rate" setting.
- Disable auto-update apps in Google Play (background processes steal resources).
- Use externally SSD instead USB-flash drives (high reading speed).
💡
For reproduction 4K HDR without lags, use network connection as a priority (DLNA, SMB or plex). USB 2.0 is limited to 480 Mbps, which is not enough for a high bitrate.
