Starting point: MKV - Multi-track container for video, audio, subtitles. Only the selected tracks carry over, so pick audio and subtitles first. Audio is resampled to the handset profile, so keep a master copy. Encode 3G2 (H.264 / AAC) from MKV at a bitrate near the source, and confirm the audio track before converting.
