  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Is there a program out there that can automatically sync audio with raw Red footage?

Pluraleyes is my go to, but that program can't handle red footage.

Adobe premiere CC will sync to timecode. I think there multicam audio syncing function will sync audio with RED footage as long as you have scratch audio.
 
Sync-N-Link is another:

For Final Cut Pro only (I believe FCP7). I generally tell clients to edit QT422 files for the offline, then we'll conform the R3D files in color correction at the very end of the project. I don't believe there's a need to edit the raw R3D files this early in the process.
 
FCP X, transcodes RED to pro res in the background right, or can it work with RED footage without transcoding?
 
I don't want to edit in FCPx, so I could sync in FCPX then XML to premiere or FCP7?

Has anyone tried Premiere's sync by audio waveform feature? How reliable is it?

The only downside i see is that it looks like you can't batch sync a bunch of clips, you have to select one video/audio at a time, then click merge, etc...

Are you sure? How? Last time I tested you could only do one take at a time but maybe I missed something new.

I always wonder if people asking this question understand that, if they actually edit with transcodes with synced audio (as opposed to syncing in the NLE and editing with the merged clips created in the assistant editing process), that the transcodes won't have the metadata (clip name and timecode) from the dual-system audio files they used to make the transcodes with in the first place. You're stuck with the audio in the transcodes. You don't sync audio in RC-X, or Resolve, for anything except offline dailies that won't be used to edit.

As further explained in this post:

Fcpx does it all. It can also do batch sync as well. I do it all the time !

For music videos , I sync all my r3d takes into a multicam clip, and can select in real time what clips I want , at what second I want it like a switchboard using number pad on keyboard. Heard the new Mac Pro can handle 16 sync clips all at once . ... Works like a charm.


Simply select your external audio, then select all your clips , and click "synchronize audio". Just like that , it's all done (providing your scratch audio is clear ).

And of course, you check to see that every clip is 100% frame-accurate, and they always are.

Lemme guess...no.

Absolutely. I use this process as well but i'm working with a TV series. Once synced I check through everything while compiling for the edit. Sometimes with poor guide audio there is a bit of fixing but this is usually quite rare. Good thing is you keep the R3Ds

Last I used -- 10.0.7 or something.. not 10.1 -- selecting the audio and the video files in FCPX and clicking "sync audio" created one compound clip with all the video clips and audio in it… I had to manually selection clip1 with audio1, and select "sync audio", which created a compound-clip1, and so on… If I could just go Cmd-A and sync audio, and it gave me independent clips, that'd be pretty great and worth trying.

The funny thing is, even when doing it manually (ClipX with AudioX) it did a pretty decent job syncing… Although I found it incredibly annoying that I couldn't go "sync audio with timecode" and be done with it.

If you can actually batch, can someone PM the exact process… I'd do it in a heart beat for the rough of a project I'm currently trying to un-clusterf***.
 
I put the process up in another thread a while back. It's the same as the one Sam Mestman put in his tutorials. I've been using it from 10.0.6 I believe. You make a multicam clip not a sync clip. From there I cut and paste the files into a timeline.

Sams tutorials are probably the best out there.

So, "absolutely", but "sometimes there is a bit of fixing". Hahaha...

Automated waveform/TC syncing isn't 100% frame accurate. Never will be.

Not sure why you would say that... audio samples at a rate far higher than 24 per second. If you are matching a decent reference track on the video with your second sound, the match will be perfect nearly all of the time.

The "fixing" that is being referred to is simply when the process goes wrong - it can't find the matching wave forms and it guesses the best it can. Maybe because of broken video track or poor reference audio. Yes, that can mean it guesses wrong. But, as others have indicated above, it is very reliable in most situations and the automation saves tons of time.
 
It's always been frame accurate with a correct sync. Terry is correct about other cases.

No question about it saving tons of time, but I've seen enough audio latency, and TC drift, to know that camera audio is usually (as in, almost always) 1-3 frames off, at least. And a good assistant editor can/should be able to sync a day's worth of rushes in under 2 hours, or half that on a one-camera shoot (depending on good slating, obviously).

On the 2-camera Alexa-shot ABC promo I did last week - every single clip with in-camera audio was off by 1 to 3 frames. Both cameras. Every single one. Got worse as the 15 hour day progressed. I wouldn't dream of auto-syncing that and handing it over to production.
