At a trackday I recorded four sessions each of about 40 minutes with RC for IOS, video source was a GoPro 4.
After downloading the videos I edited the sync of three sessions, which were off about 200ms. Now I can't export the three edited sessions (MP4+overlay). I always get a “Failed: Video/audio codec” error. Viewing the videos + overlay in RC works.
The fourth session, for which I didn't touch the synchronization, exported without problems. Synchronization is off by 200ms as expeced.
How can I get my videos + manually synchronized overlay exported. I didn't find a solution in the forum or in the FAQ.
Or is it at least possible to restore the original sync values in RC?
