    Is it possible to automatically sync external audio to a project that’s already edited in the timeline? I have a bunch of video clips and one really long audio file that would take forever for me to listen to and try to match parts of it with the clips in the timeline. I’ve heard of PluralEyes being able to do this but I wanted to know if there was another solution.

    Also, is it bad to sync after editing? I’m discovering that it seems like it would be easier to sync all the clips before editing. Although, even then, I don’t really understand how that works. Can you add external audio tracks to clips in the browser, so that when you drag them to the timeline they’ll show both the on-camera audio as well as the external audio?

    Sync clips before editing is the way I work as that leaves you with the most freedom to edit afterwards . If you have to go back into a project and sync clips cut by cut that is painstaking and a crazy. If its one or two clips, that need syncing with audio in a time line its doable,but after that it gets tedious very fast. If you have a multicam clip it not so bad to step into that clip and sync an additional track, but again try to get that done to the fullest extent possible before you actually start cutting.

    Syncing could be done right from the start.

    should have some tutorials.

    If You have multicams & external audiorecorders, it’s a good practise to let them roll uninterupted until the scene is recorded. Like if You record a koncert, it’s a hazzle if someone is using the start/stop button and creates loads of clips to sync.

    It’s way easier to just have to sync the begining of each scene, and then do the cutting.

    Good luck!

    How do you sync a bunch of video clips to one audio file? I have an audio file that was recording sound for the duration of a shoot, and it would take a long time to listen to the whole thing and try to match the audio with the various clips.

    If you are able to cut out shorter regions that contain the audio from your long clip, you might be able to sync those short, individual clips using FCP’s sync capability or Plural Eyes. I’ve never had to do that, so can’t say how to do that. Perhaps, if you export the audio from your timeline so you have a single clip, you could then sync the shorter clips to that.

    How many source video clips did you start with for the edit? Is that just one file, or a bunch?

    A bunch of video files. Some of the audio in those video clips doesn’t sound that good so I want to use portions of an external audio file I have. The audio file is about two hours long and I’d like to know what the best way is for syncing it to the source files or to the clips that I’ve edited in the timeline.

    I’ve had decent luck with multi-clip projects and single-source audio.

    I think I was bored once and did each video clip to single-source audio using AutoSync.

    There is high-end software that can do the nightmare ones.

    I had a full feature edited and needed to replace each clip’s audio with the one from an SD744T.

    I think the audio team used one piece of software in Pro Tools, sorry I forgot the name of it.
