I am new to DATV and having only just, in the last few days, got a test card on the es hail satellite, and then a caption less video, I need to find a way to add stationary or scrolling text of at least my call sign and locator to existing videos I have on my PC. Most are in .mp4 or can be converted to .mp4 format.
I am currently using a BATC Portsdown and the script for OBS from F1EJP to stream a video on my PC to the Raspberry Pi and then the networked Pluto SDR.
My OS is Windows 7.
Thanks for any info. Chris 2E0ILY
