I know what DVT is. First you have to transfer it by recording it with video capturing software. A very popular one is OBS Studios. How your camera connects to your computer and how OBS or other recording software would record it is beyond my expertise. OBS allows a wide range of settings for making video files, as I’m sure you wishing to have the best quality possible for your videos. OBS also has very active forum for support.
If you use OBS or any video recording software, make sure you test a small 1 minute or 2 minute clip before you go and record 50 hours of video and then later find out it’s not what you wanted for settings.
Once you got the video saved to some format like mp4, mkv, mov, etc… then you can import that file into Shotcut for editing. I still have some DVT’s laying around, lol.
[Edit] I didn’t know about this feature of Shotcut. This is if you have a capture card.
