AVCHD (Advanced Video Coding High Definition) is a file-based format developed by Sony and Panasonic for the digital recording and playback of high-definition video. It uses H.264/MPEG-4 AVC video compression and supports 720p and 1080p resolutions. What makes AVCHD ideal for Blu-ray conversion is that it's designed to be compatible with Blu-ray players and can be burned to DVD or Blu-ray discs without much loss in quality.

Part 1. Convert Blu-ray to AVCHD with the Free Tool BDtoAVCHD

BDtoAVCHD is a powerful yet easy-to-use tool designed specifically for creating AVCHD discs from Blu-ray or MKV sources. It generates a fully structured AVCHD folder that can be burned directly to a DVD5 (4.7GB) or DVD9 (8.5GB) while preserving high-definition video quality — perfect for users who want to compress their Blu-ray collection without sacrificing too much clarity.

The AVCHD format supports full 1080p resolution and plays on most Blu-ray players and PlayStation 3 consoles. This makes it an excellent option for backing up Blu-ray movies to a more compact medium like DVD or USB drives, while still enjoying crisp visuals on a big screen.

Why Choose BDtoAVCHD?

What sets BDtoAVCHD apart is its focus on simplicity and quality. It avoids unnecessary conversions and doesn’t require any external codecs like AviSynth, ffdshow, or Haali Media Splitter. All encoding is handled internally using x264 (and optionally x265/HEVC), ensuring efficient compression and maximum quality. Even better, it automatically identifies the main movie file, calculates the ideal bitrate based on target disc size, and prepares the content for burning with minimal user intervention.

Key Features

• Optimized Compression: Automatically adjusts video bitrate to fill DVD5/DVD9 to 99–100% capacity with the best quality.
• Track Selection: Detects all audio, video, and subtitle tracks; lets you select the desired ones manually or automatically based on language and quality.
• Chapter Support: Extracts and retains chapter information or lets you add custom chapters.
• Audio Conversion: Converts high-bitrate formats like PCM, DTS, and DTS-HD MA to AC3 or DTS Core if needed.
• Subtitle Control: Supports forced subtitle tracks that auto-activate during playback.
• 3D Support: Can convert Blu-ray 3D to AVCHD 3D or MKV 3D (SBS/TAB), and shrink 3D Blu-rays using Intel Quick Sync without losing 3D MVC.
• Multiple Outputs: Supports AVCHD for DVD5/DVD9, BD25 without re-encoding (BDRemux), and MKV (recompressed or remuxed).
• Queue System: Allows multiple jobs to be added and processed automatically, even while others are running.
• HEVC Encoding: Can encode MKV files using the newer x265/HEVC codec for advanced compression.
• Standalone Operation: Doesn’t rely on external codec packs or splitters.

How to Use BDtoAVCHD

1. Select Source File

Launch BDtoAVCHD and click "Open BD Folder" to load your Blu-ray disc or BDMV folder. For MKV conversions, use "Open Video File." If you're using an ISO image, mount it with a virtual drive tool like DAEMON tools first.

2.Analyze and Configure

The software will automatically scan the source and display the video, audio, subtitle tracks, and chapter information. You can now select:

• The desired audio and subtitle tracks
• Target disc size (DVD5, DVD9, BD-25, USB 4GB, or Custom)
• Whether to include forced subtitles
• Audio conversion options (if necessary)

3.Bitrate Calculation

BDtoAVCHD automatically calculates the optimal bitrate to ensure that the video fits your selected disc size while maximizing quality.

4.Queue the Job

Click “Add to Queue” to schedule the conversion task. You can queue multiple jobs and let them process one after another automatically.

5.Start Conversion

Once your job(s) are queued, click “Start Jobs” to begin processing. Depending on your PC's hardware and the length of the movie, this may take several hours.

6.Burn to Disc

After conversion, your AVCHD folder will appear in the configured output path (default is C:\AVCHD\...). To burn the disc:

• Use a tool like ImgBurn (recommended)
• Select the entire contents of the AVCHD folder (not the folder itself)
• Set the file system to UDF 2.50 (critical for AVCHD compatibility)
• Burn the disc

The result will be a high-quality AVCHD disc playable on nearly all Blu-ray players and PS3 consoles.

Limitations of BDtoAVCHD

While BDtoAVCHD is an excellent free tool, it does come with some limitations:

• Single Track Limitation: It only supports one audio track and one subtitle track per output. If your Blu-ray includes multiple languages or commentary tracks, you’ll need to choose just one of each.
• No Mac or Linux Support: BDtoAVCHD is available only for Windows. Users on macOS or Linux will need to use an alternative method or run the software in a virtual machine or emulator.

Despite these limitations, BDtoAVCHD remains one of the best free solutions for converting Blu-rays to compact, high-quality AVCHD discs.

Part 2. Convert Blu-ray to AVCHD with the Free Tool TsMuxer

TsMuxer is another powerful tool that can be used to convert Blu-ray content into AVCHD format. Though it’s primarily a transport stream muxer, many advanced users utilize it to prepare AVCHD discs and AVCHD folder structures. While TsMuxer does not re-encode video, it allows you to remux Blu-ray streams directly into a compatible AVCHD folder structure — perfect for minimal loss of quality.

Key Features of TsMuxer

• Lightweight and free
• No re-encoding — preserves original video quality
• Supports .m2ts, .ts, .mts, .mkv, and .mp4 inputs
• Can create AVCHD and Blu-ray folders
• Cross-platform: Windows, Mac, Linux

How to Use TsMuxer for AVCHD Conversion

1.Download and Launch TsMuxer

You can download the latest version of TsMuxer GUI from VideoHelp or other official sources. No installation is required — just unzip and run.

2.Load Blu-ray Streams

Open your Blu-ray disc or load the relevant .m2ts or .mpls file from the BDMV > STREAM or PLAYLIST folders.

3.Choose Output Format

In the output settings, select “AVCHD folder.” This will structure the output to be readable by AVCHD-compatible devices.

4.Select Tracks

Pick your preferred audio and subtitle tracks. You can also adjust stream language metadata and force subtitles if needed.

5.Start Muxing

Choose an output folder and click “Start muxing.” Since there’s no re-encoding, the process is extremely fast — often completing in a few minutes.

6.Burn or Play the AVCHD Folder

You can now burn the AVCHD folder to DVD using ImgBurn or simply store it on an external USB drive for playback on supported Blu-ray players.

Pros and Cons

Pros:

• Free, lightweight, and fast
• No quality loss due to re-encoding
• Flexible stream control
• Cross-platform availability

Cons:

• No video compression — file sizes remain large
• Cannot convert non-Blu-ray videos to AVCHD
