Have being using Video Grabber with macOS Catalina 10.15.3 and Sony Hi8 Video Set Recorder (EV-S2000). It worked on some of VHS and 8mm Cassette Tapes. But now It doesn’t work any more. Can not see the Preview Panel. There is no picture on Preview Panel.
Can check with the Recorded VHS tapes or Hi8 Tapes if there were no Hardware changed. The USB-Video-Grabber is fine if it can work with Preview or Recording.
1. Otherwise please check if the Hi8 Cassette Tape is fine by connecting the Hi8 Video Set to Monitor or TV set.
2. The Hardware Connection (usb-Video-Grabber & macOS 10.15) is ok.
3. If the macOS 10.15.3 can not find the hardware. Check the USB-C Converter or USB connection.
