    44.100 audio recording matching a 48.000 audio of the camera

     

    Hi there,

     

    I encounter some synch problems in my edit.

    I'm editing a concert on which the audio has been recorded with an external recorder at 44.100Hz, and I filmed it with a camera in which the audio is 48.000Hz, this audio just being used as a cue in order to link it with the good quality 44.100 audio.

    I can understand why 44.100 and 48.000 can be out of synch. But what surprises me, is that the picture is out of synch as well with the 44.100, as if the audio recording on the camera affected the frame rate of the video?? am sure not...

    I guess the solution is to re-sample the 44.100 into 48.000, I tried it with quicktime pro but I dont thnik its the right tool for that as the audio remained exactly the same. Guess I need to use a proper audfio software.

    Your knowledge into audio sample rates and video would be much appreciated!! It's not really clear to me. I know that all audio recordings should be 48.000, but wouild be good to know how to deal with 44.100 as well

    cheers

     Don't double post.  If you want to bring your post back to the top of the forum, just answer it with the word "bump".

    If you have imported the reference audio at 44.1 kHz you can transcode it within Avid.  Select the audio to transcode in its bin.  Click on the fast menu "hamburger" at the bottom of the bin and select consolidate/transcode.  Choose transcode and set the audio sample rate to 48 kHz and you're done.
