By default stream 0 (the first audio track, usually the main mix). If your MOV carries commentary, dubs, or descriptive audio on additional tracks, the advanced "audio stream" picker lets you pick 1, 2, 3... explicitly. The track list is shown in the upload preview so you do not pick blind.
If the AC3 format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If AC3 is lossy (MP3, AAC, OGG, Opus), the codec recompresses — at 192 kbps the difference is inaudible for most content; at 96 kbps you may hear cymbals or sibilants softening. The MOV container has no influence on this — only the codec settings matter.

Audio demux + transcode runs much faster than video re-encoding — typically 5-15% of source duration. A 1-hour MOV -> AC3 finishes in 3-9 minutes on the standard pipeline. If the AC3 codec matches the source codec already in the MOV (common for AAC inside MKV / MP4), it is a pure remux and runs in seconds.

Almost always a stream-index mismatch — your MOV had a multi-track audio layout and we extracted the wrong stream (e.g. the silent descriptive audio track instead of the main mix). Re-run with the advanced "audio stream" option set to the right index, or pick "all streams" to extract every track as a separate AC3 file.
