Capturing CRT video recording

Hello,

I have an android phone and Panasonic HC-V770 camcorder.

I tried all settings of camcorder especially shutter speed but did not work, always a black line moving on screen. shutter minimum is 1/60 and even using open camera app with shutter speed of 1/60 1/30 or other values still the same issue.

I tried Neo Geo AES and PC Engine on a Sony Trinitron consumer set. all consoles output RGB SCART and gets converted to component then delivered to CRT.

All these consoles are NTSC. I tried PS2 and Gamecube and the picture was better, while older 4th gen consoles despite no flicker but there is always a black line moving from bottom to top.

please help
