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:
hdmi_group=1
hdmi_mode=5
But when I reboot I get 60fps output, not 59.94fps.
How can I force 59.94fps?
tvservice -e "CEA 5 HDMI" --ntscis the only way to do it - put that in rc.local script? – Jaromanda X Apr 10 '18 at 2:05hdmi_cvt=1920 1080 59.94 3 0 1 \n hdmi_group=2 \n hdmi_mode=87 \n hdmi_drive=2– Jaromanda X Apr 10 '18 at 2:12hdmi_cvtstatement is ignored if the frame rate includes decimal points. – BonsaiOak Apr 10 '18 at 15:30
