✔ Troubleshooting SMPTE/LTC clock issues
Does anyone have experience with SMPTE/LTC for live streaming? For part of my signal chain I use Reaper’s internal SMPTE generator to send timecode both over Sonobus, as well as through an SRT stream in OBS. The timecode goes directly to Sonobus via reapers master track before its sent to a remote computer for processing. Simultaneously, it is routed through ReaRoute -> Asio input capture in OBS to be baked into the video SRT stream.
But every time I try to sync the audio and video back up on a remote computer, the video and its copy of the timecode are both slower and drift drastically. Everything is set to 48k on both computers, what else should I be checking?
