What video encoder is optimal for Xiaomi Redmi: H.264, H.265 or AV1?

Choosing a video codec on Xiaomi Redmi smartphones is not just a technical trifle, but a key factor in influencing video quality, file size and even device autonomy.With modern Qualcomm Snapdragon and Mediatek processors Helio/Dimensity In the arsenal of Redmi users get access to several codecs: from the verified H.264 (AVC) advanced H.265 (HEVC) forward-looking AV1. Which one is really best for your model?

The problem is, there's no universal answer.+ Dimensity 1080 hardware supports coding H.265 into 4K, But it can also "slow down" when shooting in AV1 And the owners of budget models like Redmi. 10A helio G25 limited H.264 — If you don't, you'll see the videos being snatched, and in this article, we'll take the pros and cons of each codec, test them on real-world tests, and make clear recommendations for scenarios ranging from social media to professional editing.

We'll also take into account the hidden settings. MIUI, which allow for the compulsory inclusion H.265 Even on devices where it is disabled by default, this is true for models on Snapdragon. 6xx/7xx And of course, the compatibility issue is not all players and social networks work correctly with the same content. AV1, H.265 It can cause artifacts when played on older devices.

What is a video codec and why is it important for Xiaomi Redmi?

Video codec is a video compression algorithm that determines how compact a file will be while maintaining acceptable quality. On Xiaomi Redmi smartphones, codec choice affects three key parameters:

1. File size: H.265 video-compress 1.5–2 more effectively H.264 And you can do that with the same bitrate. 4K/30fps borrow ~400 MB in H.264 and ~200 MB in H.265.

Image quality: With the same bitrate H.265 and AV1 give fewer artifacts (blurring, "squares") on complex scenes (e.g. foliage in the wind or fine details).

Processor load: Encoding in H.265 It requires 30-50% more computing resources than H.264. On weak chips (e.g. Snapdragon) 4xx) This can lead to overheating and staffing.

On Xiaomi Redmi, the codec is automatically selected depending on the model and shooting mode, but it can be changed manually through hidden camera settings or third-party applications like Open Camera.

• 📱 H.264 (AVC): Universal codec, supported by all devices and social networks. Optimal for budget Redmi (Redmi) 9A, 10C).
• 🎥 H.265 (HEVC): Best File Quality and Size Balance Requires Hardware Support (Available on Snapdragon 665)+ Dimensity 700+).
• 🚀 AV1: The most modern codec (used on YouTube, Netflix) Redmi works only software - high battery consumption and risk of lags.

⚠️ Note: Some Xiaomi Redmi models (e.g. Note 11 Pro with Snapdragon 695) are forced on H.265 It can lead to green artifacts in the video through the engineering menu. It's a firmware bug that's only fixed in the video. MIUI 14.0.5+.

Comparison of codecs: H.264 vs H.265 vs AV1 as an example of Redmi

To understand which codec is better, we will test them on Xiaomi Redmi Note. 12 Pro+ 5G (chipset 1080) three-mode: 4K/30fps, 1080p/60fps and 720p/120fps. Results (average values by 5 test):

Conclusions from the test:

- H.265 It's better than the rest of the world in terms of quality and file size, but it's warmer than the rest of the world. It's better for long-term video (concerts, travel).

- AV1 It shows better compression, but software coding on Redmi causes the battery to overheat and discharge quickly.Recommended only for short rollers (up to 5 minutes).

- H.264 It remains the most stable option for budget models and shooting in dynamic scenes (sports, children, animals).

Interesting fact: on Redmi K60 Pro with Snapdragon 8 Gen 2 codec AV1 It's a hardware-based system, and it uses 40 percent less power than Dimensity 1080, which confirms that the choice of codec is heavily iron-dependent.

💡

For most users, Redmi is optimal. H.265 — It gives an increase in quality without a critical increase in load (starting with Snapdragon). 678/Dimensity 720).

What codec to choose for different shooting scenarios

The same codec can be perfect for some tasks and completely unsuitable for others. Consider the typical Xiaomi Redmi use cases and optimal settings:

1. Video for social networks (Instagram, TikTok, YouTube Shorts)

• 📌 Recommended codec: H.264 (1080p/30fps, bitrate 8–12 Mbps).
• 🔹 Why: Social media automatically recodes the video, and H.265/AV1 And what's more, Instagram can break the sound into the H.265.
• 🔧 Settings: In a standard camera MIUI choose 1080p and turn it off HEVC extra-parameterly.

2. Professional shooting (installation, color correction)

• 📌 Recommended codec: H.265 (4K/24fps, bitrate 50+ Mbps).
• 🔹 Why: H.265 It stores more detail in shadows and lights, which is critical for post-processing. H.264, better.
• 🔧 Settings: Use Open Camera or Filmic Pro with manual bitrate. on Redmi Note 12 Pro+ turn on 10-bit H.265 via the engineering menu (#4636##).

3. Long recording (lectures, streams, timelapses)

• 📌 Recommended codec: H.264 (720p/30fps, bitrate 5 Mbps).
• 🔹 Why: Minimum processor load = less heating and battery consumption. H.265 in long sessions can cause trottling (decreased performance due to overheating).
• 🔧 Settings: B MIUI Camera, select. 720p Turn off the stabilization (it additionally loads). CPU).

💡

If you're shooting for more than an hour, use an external battery and turn off the background apps. 7xx length-record H.265 It can cause emergency shutdown of the camera due to overheating.

4. Game content (gameplay recording)

• 📌 Recommended codec: H.265 (1080p/60fps, bitrate 20–30 Mbps).
• 🔹 Why: Fast movements in games require high bitrate. H.265 It allows you to keep smooth without giant files.
• 🔧 Settings: Use Screen Recorder with settings HEVC 60 FPS. On the Redmi. K50 Gaming can be enabled by hardware coding through developer options.

⚠️ Note: Xiaomi Redmi with Snapdragon processors 4xx (Like Redmi. 9C) play-play H.265 It's going to lead to a lot of lag, and in that case, it's best to use it. H.264 lower-resolution (720p).
