OSD overlay on Video recording and more

How do you get video recording with OSD overlay? After they flight I insert USB and I get video and raw telemetry separately. Do you put these two together later (how?) or just recording video in some different way?

  1. How do you get time set on GroundPI? Its about video/temeletry timestaps being off. I connect GroundPI to phone via USB tethering, but it doesn’t get synced. Should I install ntpd manually?

  2. Where can I look for documentation of OpenHD. I already know and use
    Home · OpenHD/Open.HD Wiki · GitHub
    and this forum.
    Are there any other sources?

thanks!

On the pi with the current release its not possible to screen record. Most people are doing it by linking another device to the groundpi (like and android tablet/phone) then using screen record features on that device
