    VidCoder

    VidCoder

    A Blu-ray, DVD and video file transcoder for Windows

    ...It lets users convert video files (or rip DVDs/Blu-rays, when supported) into modern formats and codecs, making it useful for people who want to compress, re-encode, or transcode video content without dealing directly with low-level encoder settings. Because VidCoder integrates and automates the invocation of complex backend tools, it lowers the barrier for users who may not be comfortable with command-line workflows — offering preset profiles, configuration dialogs for bitrate, codecs, subtitles, and other media parameters. It supports batch processing so multiple videos can be queued for conversion, which is a big plus for users handling large video libraries or doing bulk transcoding.
