Question: sound not transferring with video
I am trying to transfer video from my canon elura 100 using the DV out firewire port to my iMac fall 2011 computer. My iMac has a firewire 800 port and the canon camcorder has uses firewire 400. Using an 800 to 400 adapter I can capture the video on iMovie but not the sound. I can control the camcorder from iMovie. Any suggestions on why the sound is not transferring with the video?
iMac, macOS High Sierra (10.13.1), Fall 2011 27"
