Thanks for the reply David. Yes the tentacle sync was set to mic level, the time code on the F8n and the tentacle sync matched. I downloaded Davinci resolve and tried and used it some clips are in sync, some clips come out still with time code sound and all out of order in takes for example if there were 4 takes of same scene first two in order then and other scene then back to the original scene. and a copy of the F8n audio is also on the end of the end of the exported files. Just so frustrating trying to sort out what is going on.
Got the Syncing to work in Davinci Resolve (operator error frame rate in Davinci)
