The DVD-Video specification limits each VOB segment to 1 GB, so longer titles are stored as sequential files (VTS_01_1.VOB, VTS_01_2.VOB, and so on) inside the VIDEO_TS folder. You can transcribe each segment separately or join them into a single file first for one continuous transcript.

VOB files can multiplex several audio streams, such as different languages or a commentary track. Transcription uses one audio stream at a time, so if you need a track other than the default, extract or remux that stream before uploading.
