The default of auto mute is off on Free Run and RTC mode and I didn't change it. The main issue might be some missing data in the first part of the LTC on CH1 of the video. After a bunch of videos, I may be an error pattern I didn't understand at first. I am using analysis tools that Robin wrote and I'll ask him about the results. > > It might be useful to use a clapboard or similar to give you an easy to > find location in the audio and video to check whether the "few seconds > off" value is always the same or whether it changes from start to start. > > -- > Chris Caudle > > > I've been filming the start of each video using the clock of one of my phones. I am looking at getting a hardware slate like a Denecke TS-3 - to keep my sanity I only use software in post :-) . I am unsure though if I want to send timecode to the slate or have it generate it. I would have to "JAM" either the F8 or the slate, if I understand correctly. Thanks for the help!
