Choose the right multichannel audio output
Blu-ray discs can contain PCM, Dolby TrueHD, Dolby Digital, Dolby Digital Plus, DTS-HD Master Audio, and other audio streams. The container and output profile determine whether LosslessConverter keeps an original stream or creates a compatibility-focused audio track.
Use Lossless > Multi-track MKV when the goal is to retain the original Blu-ray audio tracks, including Dolby TrueHD when present. MKV can hold the selected video, multiple audio streams, and subtitle tracks together without converting the supported streams.
MP4 and MOV do not retain Dolby TrueHD in this workflow. Choose those containers only when the destination needs them, and use Dolby Digital 5.1 or another compatible multichannel output supported by the playback path.
