    Hi audio pro people, I have a problem.

    I am from PAL country but this crew shot 23.976 rushes for me and using external recorder for audio.

    When I placed the audio on the timeline with video, it synced at first but then it slowly started to drift out-of-sync.

    Is there such things as 23.976 audio?! How do I convert the WAV audio to drop-frames to match the video? I did try convert video to 25P but it doesn’t work.

    Thanks very much.

    Ps. Using a mac, so pc solution is probably out, although I heard about BeSweet.

    I’m not sure this will work but try Pluraleyes from Singular software. https://www.singularsoftware.com.

    Pluraleyes is not syncing only, I doubt it is for changing frame rates, if there is such things as frame rates for audio.

    IF the audio was recorded to timecode sync then yes it will be at the 23xx fr. But if its just a wild recording then its hours mins secs and tenths / 100ths, not base 25 or base 24 etc etc.
    if you play audio at the wrong speed youll hear it stright away.
    what are you using to re unite the pics and audio. make sure the sample rate and bit depths ate correctly matched 1st. this will cause drift.

    Thanks for the piece of information. Learn something new today, and yes, I think they recorded wild with no external sync to anything.

    I am using FCP 7 to sync the visual and audio. So far it ain’t working at whatever I throw at in.

    Lucky for me, only certain part of the visual requires matching, the rest can be cutaways, so I’ll just have to manually sync 2-3 secs of visual that were used.

    Hello Chee Wee Tan and welcome to the Cow Audio Forum.

    Try Wave Agent on copies of the original files.

    https://sounddevices.com/download/waveagent.html

    Open a COPY of the file in Wave Agent and change the frame rate. Please let us know if that does the trick.

    Thanks,

    Yes! I tried one WAV file, imported it in, change the frame rate and save it and it synced perfectly without drifting! Thanks for the solution!

    On a side note, one of the WAVE file can’t be imported at all.

    Thanks a lot for this solution again!! Cheers!

    Excellent. Glad I could help. Thanks for letting us know.

    I used Quicktime 7, open that particular file, export it again as a same WAV file and then it can be open with Wave Agent for changing for frame rates.

    Must be something corrupted somewhere in the recording.

    Chee Wee Tan,

    or, there’s something in the meta data that’s not cooperating.
