My issue is now resolved by purchasing a Logitech USB camera as recommended by the BATC info.

Thanks for help

I found on the net a HDMI to CSI converter, to emulate a Pi Cam using any HDMI source
so I installed it in my Portsdown 4, connected the converter to the cam connector on the Raspberry and my camcorder on the HDMI side
Now with the "Pi cam monitor" in Menu 2 I can see the vidéo of my camcorder ! works great !
unfortunately when I specify Pi Cam as source in menu 1 and switch TX on, the camcorder image appears on the screen but he Portsdown doesnt go to Transmission ...
its a pity, possibility to use HDMI source should be a great improvement !

Unfortunately, the H264 encoding software written by Evariste F5OEO that is used in the Portsdown does not work with these HDMI to CSI adaptors.

The Pi Cam monitor used on Menu 2 and the Viewfinder used during transmit use different software.

Perhaps ask Evariste?
