Syncing audio - Resolve 14
on Aug 11, 2017 at 3:04:09 am

Hello!

I'm a longtime Premiere using attempting to cut a project in Resolve 14. I shot my project with the audio recorded directly into the A camera. The B camera had its internal mic on to capture the room audio.

In Premiere I would simply drag both clips into the timeline, highlight the audio tracks, right click and choose "synchronize" and Premiere would automatically sync them based on the waveforms.

I can't find a similar workflow in Resolve. It seems the only auto-syncing is between camera audio and audio files recorded from a Zoom or other such device.

Is there an easy way to sync the audio tracks from video files?

Thanks!

The same tool is not currently in Resolve. For now, make a multicam clip from the pair in the media pool then place them in the a multicam timeline. Then select the timeline and 'open in place'.
There are more audio tools still in progress amongst our Fairlight integration.

Of course there are ways to manually sync audio to video, even without the slate. The trouble is it's only really feasible as long as you have a relatively small ingest. If you have LOTS of clips that need syncing, that it would be nightmarish to do it by hand.

There are third party solutions also available, such as Plural Eyes, if you have the budget for such an indulgence.

Hi there Simon!

So we have had a major issue on set, the timecode between the sound device and camera is off for the entire shoot and there was no scratch track recorded on the camera itself, thus I have been tasked with syncing the old fashion way, I have got 20 scenes synced and ready for the editor within Resolve 14 but because I have synced manually and not using timecode; when I come to exporting the Proxies - I get no audio at all - I have tried numerous delivery and track settings and nothing seems to work.

I am able to get audio if I sync the clips by the Timecode (But it is incorrect so that is useless) I also get audio if I set the delivery to Single Clip as opposed to Individual Clips but then I loose the source name.

I saw that you said there are ways of syncing manually and just wanted to ask if you had any way around this, thanks so much!

Oh man, sorry to hear that. This sounds disastrous. Kind of one of those nightmare come true scenarios!!

Odd how the audio is not exporting with the proxies. This sounds to me like an oversight on behalf of Blackmagic. When you get a free moment I feel its worthwhile letting them know about this issue.

Unfortunately I don't have any answers for you right now, but give me a day or two I can look into it in further detail. It might help if you can post me a short sample of your video and audio to examine. Doesn't really have to be longer than 30-60 secs, so you wouldn't have to worry about any potential copyright issues with sharing the data.

Hi Simon, thanks so much for the prompt reply.

Haha trust me it has been!

But just after I posted on the thread I actually made a bit of a discovery.

If you sync manually on the timeline ie. bringing in video and then bringing in audio and shifting the audio into the correct position - Resolve immediately thinks you are cutting and not creating proxies thus when it comes to exporting "Individual Clips' from that same timeline, it for some reason just neglects the audio.

If you roll back to your Media Tab - you will see that the video opens in one window and the audio opens in a separate window next to it - if you find the clap and the find the spike in the respective windows, there is a link button at the bottom of the waveform window - when you click this - it actually alters the Video's Metadata. It will change the "Type" from "Video" to "Video+Audio" you can then bring that same clip onto the timeline with all the other synced clips - this then tricks resolve into thinking that the video had audio the entire time and thus allows you to export the timeline as Individual Clips with the audio attached.

Sucks a bit cause I now have to ReSync everything but at least we can move on!

Thanks so much anyways!

All the best,

Resolve does at least have the ability to sync clips into a multiclip by sound (see the Goat's Eye tut https://www.youtube.com/watch?v=hEIXhPpdOJk). I know that's not quite the same as the Premiere method.

I haven't found it to work 100%, whereas I hear Pluraleyes is more reliable. But I haven't tried it in a while, it might have improved in the last 6 months.

PluralEyes is a great product. Worth the investment if you constantly find yourself in the situation of having to manually sync audio.

PluralEyes was definitely worth the investment when I was using Premiere. Now we use Resolve, which doesn't have as good sync'ing methods particularly if your devices don't all use timecode. As a solo videographer managing two DSLR cameras in separated locations, plus audio and no slate (not practical in this situation), AND each camera with rec time limits, I ended up a couple big gaps in my A camera (for a 1hr 40 min shoot). Audio was continuous, but Resolve couldn't sync it. After a lot of frustration attempting to match waveforms, I imported everything into PluralEyes and exported to Premiere where I could either export each of the A and B cameras (as proxy to speed up the export) or mark the timecodes for each camera IN/OUT.

My production method was obviously flawed, resulting in more time in post attempting to fix it. But, I'm working alone with a Sony A7rII and Canon 5DmkIII, neither of which is a good production camera (although video quality is very nice). It was a favor shoot for a friend and it always helps to discover weaknesses in your system when it doesn't matter so much.

Perhaps there was a better method in post, but the PluralEyes>Premiere proxy was the best idea I could come up with at the time (this morning after sleeping on it).

[david fielding] "Perhaps there was a better method in post, but the PluralEyes>Premiere proxy was the best idea I could come up with at the time (this morning after sleeping on it)."
You know, we never had timecode on the film in the days of syncing sound with motion picture film, and somehow we got by with just a sync clap. But you do need a slate and a clap. Once you have that, each take need not take more than :30 seconds, maybe 1 minute at the most. If you have 200 takes, it's just 200 minutes, which is only 3.5 hours. And if you're fast, you can do it in less than half of this time. It's not that hard, and it's been done for more than 90 years.

You're so right and I do have a slate/clap. I was managing the two cameras, audio, lighting. This shoot was what you'd call a 'mindfullness/meditation' session with yogi folks (secondary content for a vlog). A clapboard might have disrupted the meditation a bit. It was 1.5 hours. My Sony a7RII and Canon 5DIII suck as production cameras.
