  • Canon 7D Audio Synching

    Posted by Sean Kapleton on January 8, 2010 at 1:53 am

    Hello

    I have just been handed a drive of Canon 7D footage as well .WAV files. I am batch processing them in compressor converting the footage to ProRes HQ 23.98 utilizing a cluster and thus all cores of this newer MacPro station.

    I wanted to know how to go about properly syncing the .WAV files to these transcoded clips.

    Any help and advice on this workflow would be greatly appreciated.

    notes from the sound guy were as follows:

    track audio recorded on a 702T HDD – transfered via data wrangler.
    Track 1 = lav mic
    Track 2 = boom mic

    13 files in total – #13 is 1k reference tone.
    No room tone as it was a recording studio so very quiet.
    Audio was running majority of the shoot even if cameras were not.

    sync via Digital slate with Time of Day T/C taken from master audio. Slate clap at beginning of take.
    24Bits
    48K
    23.97ND
    .WAV files

    This is filmaking 101… You need to line up all the audio BY HAND to the picture. On each audio cue you’ll hear the take number called out and the sticks SLAP (this data should also been on audio cue sheets). You need to fine the video file that corresponds and match up the audio SLAP with the sticks coming together in video.

    It is also poor forum etiquette to keep asking the same question again each day.

    Looks like they shot a digital slate and made your life ‘easy’.

    ok thanks for the sarcasm guy.

    I meant more like is there a way to link the two once you find that sync point in the time line as in like best practices for this procedure…would it kill you to just reply with something not negative, what has you SO jaded and bitter – maybe if it bothers you so much just dont reply to the post?!

    Also I posted it into the basics forum but got no response and my original post only got one response from a gentleman trying to sell me software which is not really necessary at all in this case. I just wanted to try to get a better response after I had gotten further information from the sound guy – had i edited my original post or added on the added info would i really have gotten a response…probably not.

    Regardless thank you to those who gave feedback that was positive and helpful and not condescending and to those who did I apologize if i wasted your interweb time with my question.

    Dude,
    Mellow.
    I myself had my finger on the ‘ move to basics button’.
    Sync in timeline, select audio / video, press Cmd L (link), drag to bin if you like.

    And now i WILL press the button.

    Why would seeking an efficient workflow for dealing with DSLR video shot with double sound qualify as “FCP Basics?”

    And why would the OP feel that it was such an insult when someone suggested using an inexpensive piece of software to help with the syncing, most likely saving the cost many times over? Unless he works for $7.25/hour.

    I suspect Canon and the other video camera manufacturers are right now busy trying to figure out how to put DSLR video technology into a traditional “video camera” that can justify a sticker of 4x the cost of a Canon 5D or 7D.

    In the meantime, I think we should have some compassion for the pioneers with arrows in their backs.

    (I’m not one of them.)

    [B.J. Ahlen] “Why would seeking an efficient workflow for dealing with DSLR video shot with double sound qualify as “FCP Basics?””

    Cause this was NOT the question, the question was how to marry two clips after syncing.

    [B.J. Ahlen] “And why would the OP feel that it was such an insult when someone suggested using an inexpensive piece of software to help with the syncing, most likely saving the cost many times over? Unless he works for $7.25/hour.”

    Cause the OP had only 12 clips, so buying software / installing / finding out how it works makes no sense for just 12 clips.

    [B.J. Ahlen] “I suspect Canon and the other video camera manufacturers are right now busy trying to figure out how to put DSLR video technology into a traditional “video camera” that can justify a sticker of 4x the cost of a Canon 5D or 7D.”

    Rumor is that Canon bought out GlueTools plugin. I have never seen paid software from Canon, so i guess some of teh trouble will be over soon for free.
    (but meanwhile there is still my (free) QTchange application to add TC to Canon clips, and my (not free) AUX tc reader if you have a lot of syncing to do.

    [B.J. Ahlen] “In the meantime, I think we should have some compassion for the pioneers with arrows in their backs.”

    True, but this trhead does not fall in that light.

    To be fair, the Basics forum isn’t heavily trafficked.

    It’s not sarcasm – I read your post as wanting to know how to sync dailies from a 2 system shoot. That’s 101, at least when I was in college and we still shot film 🙂 Didn’t mean to take a jab
