Hi. Thanks for the comment! I don’t believe USBA support dv transfer. There are FireWire to USB adapters on the market but I don’t think those adapters support DV transfer.

Hello. Thanks for bringing this to my attention. I was not aware that Apple stop selling the Thunderbolt to Firewire 800 adapter. You can try checking other stores like Adorama, B&H photo, or eBay to see if they are selling it. The other method is to use the composite connection (yellow, red, white cable) or s-video from your camera and connect it to an USB video capture card. Although that won't be capturing in DV quality.

Hello. Thanks for the comment! If you want to edit the video after capturing it, then you will need a video editor. OBS studios doesn't have video editing capabilites.

@@TechThatDoesntByte what does it mean I didn't get sorry

Hello. You don't need a video editor in order to capture your mini dv tapes. The OBS studios software is a recorder. OBS studios captures your mini dv tapes and records them. After it records it makes the video into a mp4 file. If you want to cut out/remove certain parts of the mp4 video after you have recorderd with OBS studios, then you will need to use a video editing software such as iMovie, Capcut, or other video softwares that will give you the ability to cut your videos. I hope this helps!
