Topic: Synch 1080p video with separate audio

[u2_fly_2]

Greetings to you all in videoland,

I once got permission to record multiple audio+one source video at the same time...I have uploaded all the separate sources in the past...but now I am looking for someone who could take the audio source and synch it with the one angle video source...(MTS files)

The band might use it as promo (even though they probably don´t really need it because they have been around for over 50 years) so it would be great if someone with knowledge of these things could do a good synch of the audio and the video.

I should mention that approx. the last 3 songs are missing as I had some problems with the batteries of the cam...otherwise everything else is complete.

There is no hurry...you can take all the time you need...even years...I don´t want you to feel pressure...but rather as something fun...if you are up for it 

You can also PM me for further info and I can send you the audio sources so you can compare...feel free to increase those too. I just ask not to use too much treble as the band should sound quite "bass heavy" with two bass players :-)

If you want to have a look at my video master source, then please check the two Youtube streams here:

I regularly do this with PluralEyes 4 Standalone

[Fatah Ruark (aka MIKE B)]

DaVinci Resolve does this. Fairly easy with plenty of YouTube videos to show you how.

I do all this manually myself....never used any software assistance but you should  NOT be time stretching or shrinking the actual video as that will be very noticable....only the seperate audio.

PluralEyes 4 is some ancient code, and it does sync-drift correction on the audio file only, if it is needed

Video frames aren't touched or removed

Thank you very much to all who contributed with the know-how

+1, super easy in DaVinci Resolve. And it’s free! Incredible.

Here is a video of how to do it in DaVanici Resolve and its free.

I also do it manually ... mostly since that's the way I've always done for the past 20+ years.  But there's another reason for doing it manually, that I don't see people mention much:  the audio and video in the original video isn't always in sync.  In fact, if you're any distance from the stage, it definitely isn't going to be in sync.  So after you sync the two audios, you also have to sync the finished audio to the video.  If it's off by just 1/10th of a second, you will hear the drum beat when the drummer's sticks are above his head.  HINT: sync by watching the drummer's stick hitting the drum - do not try to sync just by watching people's lips (while singing) or hands (while strumming a guitar).  To get the exact moment the drummer hits the drum, pause right before the drum hit, and use the F key to move forward one frame at a time (works in most video editing programs).

Having said all that ... now that everything is digital, syncing is a lot easier.  With analog sources you have to deal with drift (both audio and video) that can fluctuate throughout the recording, etc.

Excellent point. For handheld with built in mic, the further the camera is from sound source, the longer the delay between picture and sound, but our brains make sense of it. If there is nearby crowd noise, I would be very hesitant to try to sync sound directly to picture as one might do with a broadcast quality source.
When picture leads sound, our brains interpret that as distance.
When sound leads picture it just looks WRONG.


What I do is process the video with whatever captions and end fades I like, then import the audio from that into my workstation software to make a cut of the better audio to match. Then just replace the phone sound with the Neumanns or whatever mix I've been able to come up with.


Like this, iPhone sound replaced with KM140's dead center, slightly FoB, camera and mics were very near each other.

I was looking into Davinci Resolve about a year ago and I understood that it needed a specific graphics card that I did not have. Maybe I misunderstood.

Not a specific card, but it does require a decent card. Most recent computers should run it fine. You can always download and install to see if it will run it. It's free.
