newbie, need help syncin up drum set (2 cams)

[Jon Barrie]

Video cannot be moved by less than it’s smallest sample (frames per second). Audio can be moved by it’s own smallest sample (sample rate) that means video is a frame a time, but audio can move in its 48Khz or 44.1kHz sample rate.
This function is activated in the small triangle top right of the timeline panel “Show Audio Time Units”. Switch it off once you’re done. This shift can only work in the timeline, not the source.
If the vision is out – it’s out.
Generally the vision leading the out of sync audio can work, you see it then you hear it. Cause and effect. But hearing it then seeing it won’t work as it disturbs the cause and effect concept our brains accept.

How many editors does it take to change a light bulb?

thanks for your help,

im very surprised that there is not way i can sync this up. is there maybe a different video editing software out there i could try?

im sure im not the only one who has sought after such a solution as precision video synchronization…

I think that you misread Jon Barrie, John.

From what I just read, he didn’t say it couldn’t be done. He told you how it could be done and the method he’d use to do it. He also touched on the psychology of vision and the brain.

You may wish to rethink what he said as there is no video editing software that is going to know what to do in automating aq fine-tuning of the visual-to-audio syncing in your project — it is going to take a human being. And regardless of what tool you use, it is going to come down to that.

Good luck on your project.

Best regards,

John,

do you have to views, each from a separate cam both shot at the same time? Did both cams have audio? you have to find a very noticeable event that both cams saw. with cam 1 on a video timeline, find that event, then set a clip marker (unnumbered is fine). un-enable that video line…now, find that same event (as close as you can) on the video line that has cam2…again, set a clip marker. OK, now move one or the other video lines to line up the two clip markers and re-enable the cam1 video line. Hopefully, if the event was something that was very short, like a still camera flash (which you can use in the future to intentionally cause an event to sync to) then you should be fine .. if it was something that wasn’t so precise, for example someone’s hand motion or walking past an identifiable point, a drum stick strike, whatever then you may have to tweak the sync by moving one video line or the other a few frames. You can also use the audio and try to line up wave forms if there’s a loud or sudden audio level change. At this point, it’s basically trial and error, but you should be very close based and all you are doing is tweaking.
