BDtoAVCHD is able to detect video file properties, audio tracks and subtitles and use them in the output file.
You have the possibility of selecting the tracks you want to convert and the size of the output file before conversion.
The conversion process is possible without you needing to install all kinds of codecs to your computer, such as avisynth, ffdshow or Haali media splitter.
The main features of BDtoAVCHD are: being able to extract all the information from the video file (image, audio, subtitles); recognizing and maintaining chapters or allowing you to create new ones; identifying the main .m2ts file for the movie by just selecting the BDMV folder or Blu-Ray root; calculating the video bitrate necessary to fill the output DVD; re-compressing the video using x264 64-bit if the computer supports; batch processing; creating a BD-25 without re-compressing video; using MKV as an alternative output and 3D ready: from Blu-Ray 3D (MVC) you can obtain a 3D SBS AVCHD or MKV (side-by-side).
On the other hand, video processing takes some time and you cannot extract only a certain part of the movie; furthermore, you can’t preview frames as they are converted.
All things considered, BDtoAVCHD is a tool worth trying; it allows you to convert BD movies easily, without needing to use complex options. This converter is being constantly updated and it's available for free.
Changes in BDtoAVCHD 2.1.7
- Fixed: in some interlaced sources (AVC 29.97i / 25i) incomplete conversion due bad frame count.
- You must have Java installed (no included) as used by the BDSup2Sub program included in the installation.
Blu-rays cannot be backed up on DVDs unless you reduce their size; at the same time, it is important for users to preserve quality, too.
