I'm trying to set up a Raspberry pi to output video to an ancient TV transmitter which requires HD interlaced video at 59.94fps.
The Pi HDMI output is connected to a BlackMagic micro HDMI to SDI converter, which reports many supported formats, so auto-detection doesn't work. I believe I need to force the correct video output, probably with something in config.txt.
I can temporarily enable the correct output format with this command:
tvservice -e "CEA 5 HDMI" --ntsc
I can save the
CEA 5 HDMI part to
/boot/config.txt like this:
But when I reboot I get 60fps output, not 59.94fps.
How can I force 59.94fps?
