My understanding was that shot name metadata more or less lives at a sequence level. It refers to sequence’s shots. It doesnt live on the segment, it lives on the sequence. That helps me understand it.
I think i do something similar to PlaceYourBetts…
If your segment names are simply longer versions of the shot name like below for example,
shot name = ABC_sh001
segment name = ABC_sh001_grade_v1
Or something similiar, I select all the conformed segments (now lacking a shot name), then use this script to copy the segment name to the shot name, then open the sequence and use the Conform tab to bulk edit the shot name column back down to to the actual root shot name. The bulk edit thing is very handy.
