 > Actually, it's the other way around; [0:0] & [0:1] are from the graph
 and [0:3] & [0:4] are from '-map 0'. Yes, that was surprising, but it's
 not really the issue.

 Check again. From 3.log

 ```
 Stream #0:0 -> #0:0 (mpeg2video (native) -> hevc (libx265))
 Stream #0:1 -> #0:1 (ac3 (native) -> ac3 (native))
 setpts (graph 0) -> Stream #0:2 (libx265)
 atempo (graph 0) -> Stream #0:3 (ac3)
 ```
