BDtoAVCHD is a free tool to create AVCHD discs from Blu-Ray or HD MKV files. As output we get the folder structure ready to burn to a DVD5 or DVD9. The AVCHD format allows playback the same type of content that a Blu-Ray and holding high definition (1080p) but on DVD5 or DVD9 media. It is ideal for backing up Blu-Ray with much smaller size and maintaining high quality. The recorded discs obtained are compatible with almost any Blu-Ray player and PS3. Also can convert Blu-Ray to MKV and Blu-Ray 3D to MKV 3D SBS (side-by-side).

Small fixes and general improvements.

Version 1.4.0 (04/23/2011)

New: MKV as alternate output format. Allows to convert Blu-Ray to MKV, recoding the video (CRF) or creating a BDremux.

Improved: accepting as input MKV files with header compression.
Fixed: when converting a Blu-Ray with the main file split into several .m2ts parts and selecting the TrueHD audio was kept AC3 core only.

No 60p output for BD-9.

Oct 14, 2017 Version: v2.7.4 OS: Windows 10 64-bit Ease of use: 10/10 Functionality: 8/10 Value for money: 10/10 Overall: 8/10


In order the program can calculate bitrate correctly when DTS-HD/TrueHD audio is selected is necessary press "Scan Bitrates" button and wait to finish 100% before add job in queue.

The feature exists and works fine. Use it!

Dec 25, 2015 Version: 2.5.1 OS: Windows 8 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

I really don't like posting negative reviews of free software. But there comes a time when authors don't address bugs that it becomes necessary. In general authors of free programs do a fantastic job with their programs and they should be commended for their willingness to donate their time to others.

This program however, has a really frustrating bug - it can't get a bit rate correct to save it's life!

I've been using this tool since 2.4.5, I've posted an earlier review here about the issue, and I've contacted the author via his website, and gotten nowhere. Were it not for AVCHDCoder's requirement to use Java I would have dropped this program by now.

With HD/MA, TrueHD etc it NEVER gets a bit rate correct the first time. It will create output that doesn't fit on a 25gb Blu-ray disk. Output has been as large as 1gb oversize. What's the point in having a bit rate automatically calculated if it is always wrong?

Dec 22, 2015 Version: 2.5.1 OS: Windows 7 64-bit Ease of use: 8/10 Functionality: 4/10 Value for money: 7/10 Overall: 6/10

I have never gotten BDtoAVCHD to work fully correct. Every version there is plenty of discovery, what works and what doesn't. However, I continue to try and use BDtoAVCHD, simply because it does things none of the other programs do. I applaud the willingness to try things other programmers seem to inconsider too difficult to try. While it doesn't always work out for me, it is always successful enough to be worth the time to try things.

For example, currently I'm trying to compress the hobbit movies I just purchased in 3D. I do not have 3D TV, so this is mainly for future use. So I want really great 2D encoding, with the 3D there for when I need it. MakeMKV will happily rip me 32 GB mkv files, but my NAS solution simply can't serve the files to my media player fast enough. I need compression without losing the MVC player. Enters BDtoAVCHD. First I had problems with the virus scanner, then I find it crashing with "no free frame surfaces" error. But I bet eventually I find a set of settings that work. Which means I will have accomplished with what none of the other free programs I have tried can do.

Certainly plenty of room for improvements and new ideas to make this program better. However, for a free program I'm in no position to complain, and will happily take any improvements that come.

Nov 29, 2015 Version: 2.5.1 OS: Windows 10 64-bit Ease of use: 7/10 Functionality: 10/10 Value for money: 10/10 Overall: 9/10

Amazing tool Sir,
I'm interest in the MVC encoding part(Full ISO 2D+3D), BUT...
There's no support for Multi Audio Tracks or Sub (Please, Please...)
Is there any possibility to include the original bluray menu into the final ISO.
And Finally, If You can add a feature to merge 2 Disc version 3D Movies(like The Hobbit+Titanic...) into 1 MVC Encoded Bluray ISO.
