BDtoAVCHD is an easy to use video converter that aims to help you convert Blu Ray discs and MKV files in order to store them on smaller discs. The program can be used for changing the video and audio encoder in order to reduce the size of the file.
If you want to backup your Blu Ray discs on your computer or burn the movie to a DVD, you need to compress the video file in order to save disc space. Although this usually means a lower quality, it is a necessary operation in order to fit a Blu Ray movie on a simple DVD.
This application is designed to detect the video file properties, audio tracks and subtitles in order to use them in the output file. You can select which track you want to convert and the target file before starting the conversion.
When you need to convert the movie for a single or double-layer DVD, you just need to select the target media from the main window. The program automatically adjusts the conversion settings and informs you about the output bitrate and overall quality.
The program is designed to perform multiple conversions and allows you to specify the parameters for each job before starting the operation. Since the video processing can take a lot of time, you have the option to shutdown the computer when the process is finished.
Although the app is able to detect the video chapters, you cannot specify which part of the movie you want to extract. Unlike other conversion tools, it does not allow you to preview the frame while it is converted.
To sum up, BDtoAVCHD is a simple tool that intends to convert BD movies with minimum configuration. However, you need to test it and assess the results for yourself before using it to backup your disc collection.
