Need sugestions to solve a syncing audio problem

Hello guys and girls and everyone in between, so here are my situation...

I'm editing a music video in a jam session style where the cameraman forgot to turn on the camera mic, so all my clips are muted. My "lucky" was that almost every shot was a sequence shot from the beginning to the end of the song... :lol: :lol: :lol:

I already synced the clips with the final song by reading lips, but the way I found was to made every single clip as a track and stack then up. But now it's a nightmare to do the first cuts and put it all together.

I thought about render all the clips separately then restart the project, but I'm afraid of losing the BRAW quality. (can i render something in BRAW?)

What do you guys think? There is a better way i don't know about?

While you can’t render out BRAW, you don’t lose much or nothing at all if rendering out in one of the 12 bit formats.
Even less so f you make a rough grade first in case some shots are really off.
But don’t clip anything yet, keep the whole range in both highlights and blacks.

I use multicam clips. In resolve 17, it’s pretty easy to go from the timeline you’ve already synced to a multicam by first converting to a compound clip, then converting the cc to mcc. In the future, I’d start as mcc though, to avoid the extra steps.

Using mouth movement plosives is usually good enough to ballpark sync for music videos. You can always tweak after you rough in an edit.

Generating proxy media helps a lot to get multiple streams to play back in a multicam, although .braw’s pretty speedy, and you might not need to.

For other applications, I’ve also just learned that multicam clips also work pretty well nested inside take selector clips, which opens up the possibility of using multi-multicam clips, which sounds kinda meta, but really makes perfect sense when you have multiple cameras and multiple takes. Powerful stuff.

Generally, if you start to think about multicam containers as a place to perform sync, they’re very flexible for use-cases you wouldn’t normally expect. Music videos, though, are a very typical application for their use.

Thank you Jason, I had complete forgot about compound clips... :?

So what I did was to create a new timeline, past each clip with it's right part of the song, then compound the two into a new take. Now I can star editing like if the clips had audio to begin and don't need to go mad with that monstrous timeline. :D

I tried to use the multicam but at first glance it felt pretty scary... Don't know if I did it right.
Create new multicam clip with select bin, then Davinci created a new folder with all the files inside the Master Bin, and gave me one big clip with tons of cams.

After I finish this film I will dive into it.
