I own an HD100 and the BRHD-50 deck.
I would say its a waste of time and resources to ingest anything but HDV. It won’t improve at all by converting it and if you have a modern Mac system it won’t slow you down at all.
Capture your footage, edit etc..
when you have a completed timeline ready to render for DVD for example, save your project delete any renders you did, and change the sequence codec from hdv to prores and render that out .
It really is the best cleanest way to work with HDV.
