Tools - Multicamera - Synchronise Audio To Align Events - AWFUL

VEGAS PRO 17

Someone help me out here?

I've been using Vegas pro 13 for 5 years but got tired of minor sync issues in my videos from manually lining up my clapper by eye.

I had someone recommend Da Vinci Resolve which isn't just free... but does this for me at the press of a button, flawlessly.

I decided to not switch to the freeware and instead spend a fair amount of money to remain loyal to the software I know because I didn't want my workflow interrupted.

So someone tell me... why does this feature simply never work? I'm not talking about being a little off. I'm saying that it's off by MINUTES. I thought maybe my file was just too long, so I did a test just of me looking at the camera and clapping... nope... off by miles. How?!?!?!

I'm extremely unimpressed that I've spent all this money based on one feature... and it doesn't even close to work.

What's the deal?

You've got me curious. VP is supposed to have a feature to do this automatically? I'd never heard that. Where is it?

I've been doing it by eye for the last year and really, haven't found it that odious. One thing that helps a ton is to expand the audio waveforms with shift-up arrow. After that it's easy to line up the tracks and group them after alignment.

You'll find it in the Tools/Multicam options though it does not need a multicam project to be used.

Unfortunately this tool often just fails. Sometimes it does nothing at all, sometimes the clips will be off a large amount. Sometimes it works.

I have done numerous multi-cam edits and never did I rely on a product to do it for me. Especially something like a figure skating live event is impossible to sync via audio only. The rink is 200ft long and that by itself causes delays. All I do use Vegasaur to make a video wall of all tracks, line them up by visual ques, then a general camera color matching on media level and only then do create my multi-cam track.

The only reliable way to do it in Vegas is using TC but that would require all cameras to have synced TC or using gen-lock.

This auto-sync feature still need further work.

The one way to increase the speed and the accuracy of the audio sync is to only select a small region on the timeline and then select the events you want synchronized. If you select an area where you know audio is the same but not quite sync'd up, the tool should be much more reliable.

God bless!!

If we spent money buying, then spend also time learning: 

1, drag 4 clips onto timeline which are shot synchronized, or say, their audio has the same content.

2, Ctr+A=select all; Enable Multicamera Editing; Synchronize Audio to Align Events.

3, Vegaspro gives you the result after a while.

4, create Multicamera Track and do your job.

@VEGASDerek hi,

I have 3 small talks: 
1, the mvcplug.dll still has bug (no audio signal levels)
2, We use the folder 360 for the 4 plugins, why not give them the names as 360° Stabilization, 360° Stitching, 360° Rotation and 360° Planet?
3, Acidpro 10 released it's VST3 Sidechain Plugin, can we get this as a benefit (in VST2 e.g.), you see, we already have the eFX Compressor.

Thanks, Derek! Didn't know it was possible to select a small region, although this requires that we have some idea of approximately where our multiple clips belong in relation to each other. Not always possible when you have 100 clips from a 4-hour event, though.

Personally, I gave up on Vegas audio sync a long time ago, and purchase Syncaila, which works incredibly fast and accurately.

Sorry to be blunt... but what part of my original post led you to believe I don't know how it works? I know how it's supposed to work... it just doesn't work.

I'm glad it works for you, but numerous users are reporting that it doesn't. I'd like to know when (or even if) this will be looked at because as it currently stands, it's useless. Even if it DID work next time I try, it still undermines the point as I'm now going to have to check carefully that it did indeed work.

When doing short shows I don't turn the camera off till the end. That way I only need to align the beginning of the 1st clip from each camera track and the rest falls into place. For longer shows, only turn off for an intermission. And I do it the way @VEGASDerek suggests... just select a region with a handful of prominent peaks across tracks and it runs much faster.

My take on this is indeed start and stop the cameras about the same time and stop the same. Then you only need to sync it once.

And it is absolutely possible to do it only by using the audio wave forms, but I admit, it takes some practice and some experience with reading the displayed "peaks and valleys".

I tried this sync feature several times in Vegas and unfortunately it NEVER worked. Once, as I tried to sync more files at once, it processed for about an hour and then did nothing. :( Terribly frustrating.

The old way "syncing by clap" is still the best method, really.

@LEvi-Clay I use Pluraleyes, superb and fast. If you have stills to sync, or not, you can use the video clips/stills date/time values to get things roughly where you want them, then waveforms etc.

One project I had some time back with a mixture of video/stills, I made up a spreadsheet to assist in placement of stills, of course you must remember that a 5 second still on the timeline really doesn’t occupy 5 s.

and instead spend a fair amount of money” Maybe spend a little more and buy say Pluraleyes, saves a lot of grief.

Even better if you do any rock concerts... sync on a stage light as it changes color. 🚥

Try using PluralEyes from Red Giant Software, its the best at what it does and integrates flawlessly into Vegas Pro 13 - 17....... No need to disrupt your Vegas workflow.
