DV Capture Problems with FFMPEG

[Jhyland]

Trying to capture video from 20 DV tapes to my Mac using FFMPEG pro. Consistently get the following error (below), but the capture seems to be fine. I am an absolute novice at this, and don't wan't to continue if I am doing something wrong. Using a CANON VIXIA HV40 and 2017 15inch MBP running macOS Ventura 13.6 .

Any thoughts?

The terminal command used is : ffmpeg -f avfoundation -capture_raw_data true -i "VIXIA HV40" -c copy -map 0 -f rawvideo ArchiveDV18.dv


This leads to the following error message:

for the selected framerate error see here - https://stackoverflow.com/questions/38498599/webcam-with-ffmpeg-on-mac-selected-framer...upported-by-th

and for the error "Selected pixel format (yuv420p) is not supported by the input device"
try adding -pixel_format nv12 to your ffmpeg command.
