This is a note based run down on how to easily jam sync video and audio in post.
Set up Tentacle System:
This video is helpful for the TENTACLE system setup, do not use it for the RESOLVE part as he gets very confusing in the post section:
On Camera Black Magic 6K:
-Set audio input to 3.5mm mic left and then 3.5mm right
-Turn down sound on left side or on the audible metadata side, so you still have the OTHER side for the scratch audio!
Post Procedure to Jam Sync:
-Import footage to Resolve and create proxies now, if needed.
-Now navigate with Resolve's folder/drive search and open the all the audio files needed - drag in the files for the audio all in, with the folders to the Media page, so that they are in the same section as the imported footage in the media page too
-Hold shift and click the first and the very last VIDEO clip, right click and click UPDATE TIMECODE FROM AUDIO TRACK
-Finally, click and highlight ALL THE VIDEO AND ALL THE AUDIO TRACKS right click them all and hit AUTO SYNC AUDIO BASED ON TIME CODE
