Just start this commentary at the very start of the movie when you press play. You should be able to hear parts of the movie behind Matt Reeves talking so use that to make sure you're still in sync.
Watch this commentary track alongside The Batman (2022). Some sections have been muted to avoid copyright. These sections were just audio from the movie, not apart of the commentary track. The black screen is just so the video could be a few hundred megabytes to upload instead of half a dozen gigabytes, because I had to upload it over and over, muting different sections until it would no longer get auto blocked by YouTube.
