    I just learned the short I have taken on will be shot with external audio source.

    I have been fortunate enough to work mostly with audio fed into the camera.

    Having no AE, I will be faced with syncing up myself.

    What’s best practice, here?

    Create a sequence for each good take and syncing that way?

    Or by camera card each day?

    Not sure how the audio and video will be coming in, so I am

    trying to allow for all contingencies. I watched a good tutorial yesterday

    on syncing and creating Proxies in Resolve, but I’d rather stay in Avid.

    I worked with this years ago as an AE, but we were blessed to have a PA

    sync all for us.

    Make sure they do record guide audio on the cameras. However poor the quality is.

    Make sure they use a capper board correctly marked up with scene take etc and make sure that clapper info is narrated at the start of each take for the audio file.

    I tend to go through the video clips and add the scene and take number to each clips column metadata.

    I then do the same with the audio clips (listen to the narrated info and add that to the clip metadata

    You can then match video and audio clips and if they have guide audio on the video clips sync them using the audio.

    If not you have to mark the In on both video and audio and sync via that (unless really lucky and they use timecode that matches)

    Be aware that if they mess this up you will have a mountain to climb in Post unpicking it.

    I don’t have much input right now, as the shoot progresses. The cam will have scratch audio, the TC situation is unknown. Crossing my fingers on the experience of the DP!

    My main question is the 1-2-3 steps in Avid to sync this in the most efficient way possible. Rather brutal deadline. I know you can autosync and create auto sequences in Resolve, is there a corollary in MC? Just need the order and method for this so I don’t waste time.

    Thanks!

    MC has similar AutoSync features. If shot with common timecode, you can select all picture and sound clips for a given shooting day, and choose Clip->AutoSync.

    If not shot with common timecode, you need to either set markers for the clapper board, or you may try and use waveform syncing.

    I wish I knew about the TC!

    Guess I’ll find out how much the DP knows 😉

    They are still shooting.

    I have had varying success in the past with waveform sync, so …fingers crossed!

    Thanks much for the replies.

    Ditto everything Pat is saying, and I’ll keep you in my prayers cuz it sounds like you’re going to get screwed on this. If you can be a choosy beggar and get away from this project, I would.

    If you have to/can sync using waveforms, i would suggest resolve is quicker at it. However there is a pretty good gotcha, if you want to edit in Avid, and the sound house wants to sync to the original audio…which they probably will.

    Check out this video. It (hopefully :)) does a good job of showing the pitfalls, and solution to doing dailies in Resolve, using external audio, but editing in Avid, and not losing all that precious audio source information.
