To transfer a standard video signal (PAL) to your computer via the PC's USB interface, a video grabber or capture USB stick is ideal. These video-to-USB converters (some also offer audio transmission) are designed, among other things, to digitize older videos from VHS tapes. This means transferring them to your PC to save them to your hard drive and/or burn them to CD or DVD.
More information will be available soon in a new video. I'll share my experiences and the grabbers I used (as of February 11, 2021). Regards, Jürgen
