2 Clarifications -
Regarding the syncing of audio to video files - In the United States, this is the job of the assistant editor. Really, no person on the set should be asked to do this as it's someone else's jurisdictionally protected job. This may be the case but it certainly hasn't stopped producers and interestingly enough, editorial houses from requesting that it be done. However like many other recent developments, the whole topic has become a bit of a gray area. We'll see how it all shakes out. I would not encourage anyone to violate any rules or regulations or to do the work of someone else if asked. How you choose to use any software or hardware discussed on this site is completely up to you.
In my previous post on Resolve Lite, I said it's great for generating a production's "deliverables" on the set. What I should have said is "editorial media" which is the most commonly requested deliverable. Resolve excels at this but isn't the best solution out there for creating multiple files sets simulataneouly with burn in's, etc. There are several dedicated systems available that can do this with far greater efficiency. We'll take a closer look at those on this site in the near future.
