For those not familiar with Plural Eyes, it is a small standalone program and plug-in by Red Giant, for editing suites that will sync audio from different sources.
To put it into perspective, imagine that your recordings from your main camera, separate audio on a recorder, like a Zoom H4n, perhaps a second or third camera or even a few DSLRs. You bring all that media into your editing suite and now you need to match the audio and other the camera clips back in sync again this can be quite tedious and time consuming. So enter Plural Eyes, a program will now allow you to match/sync all those little clips back up again. In days gone by you would have to use free running time code on each (expensive) camcorder on the job or if you were on a budget, clapping or firing of a flash would help in the edit suite. That would be fine for cameras running continuously but not those turning on and off randomly during the day.
The last time I used this program was when it first came to Sony Vegas a good few years ago after a NAB event, and have to admit found it a bit slow (probably those old single core machines) and found with my work flow I was quicker at the time.
But times have changed and I now have a couple of audio recorders and at least two cameras and syncing them all up takes quite a bit of time, so lets see how it handles things today.
So to try it out I placed a Pantomime I had filmed on the time line un trimmed, this was 2:22 minutes long (they seem to get longer every year).
The main camera was added in chronological order (top track). The audio clips I have swapped over, so the green highlighted clip should be at the beginning on the left. The two small video clips are just bits filmed before the show to test the camera settings and so not part of the final show.
!! do not add any music, voiceovers, sound effects or any other un related audio at this time.
To run Plural Eyes, go to Tools > Extensions > PluralEyes 3, this brings up a window, showing the layout of your clips. You may also notice that the headers on the tracks also light up while PluralEyes loads, in my case blue.
If you highlight the clips using the CTRL+ clicking you want syncing, PluralEyes will only deal with these clips
To get things going, press the “Synchronise” button and little yellow arrows will flash across the clips and finally sync the items up for you. In this project it took 12 seconds, yeah I know I could not believe it either, wow that was quick.
The unrelated clips have been moved to the end, they are songs in the main production and was hoping to fool PluralEyes to sync them up, but it worked out they do not belong anywhere in the main production.
You can move the cursor about on the time line and preview the audio and then press the play Icon beneath the preview window to see if it has done the job correctly. You also have the option to save the project , from File > Save project in its own right. this means you can send the saved file to a third party working on the same project and they can use your sync.
To get back to your main project , click on the “Export Timeline” and your clips will be re-arranged to be in sync. A quick play and all sounds well, but how good has it done it. I had placed markers on the main video and audio clips when I originally edited the project last year, you can just see them in orange, with SYNC next to them. As you can see it has lined them up perfectly .
