I have found a way to capture from firewire for kdenlive, install Lives video editor from repository, use this program to capture from dv camera with firewire this stores clips in home folder, it can then be loaded into kdenlive timeline. hope this is useful.

Well that is sad. Kdenlive used to do firewired capture directly. https://userbase.kde.org/Kdenlive/Manua ... g#Firewire

dvgrab command line can probably do it too https://linux.die.net/man/1/dvgrab
