24fps audio in 60p project
Hey all,
I am cutting a project that was shot on Super 16 and telecined to DVCPRO HD 720p60. The video is MOS and the sound has been recorded using a hard disk recorded to BWF files.
I loaded the DVCPOR HD via firewire into FCP using the appropriate easy setup and i imported the WAV files from the sound guy.
I am syncing all the dailies and problem i am having is that the Timecode clap that sound used was is in 24p but my audio came into FCP as 60p so the don’t match.
this is forcing me to use the audio of the clap instead of the timecode of the clap. The timecode on the clap and the sound files are jam synced.
any ideas how i can get my audio to run at 24 fps so i can sync this stuff a little quicker?
any ideas would be much appreciated.
best

Hi Mustafa,
One thing you can try is to create a 24/23.976 project to import the BWAV files. From there you can drag them to 60fps NTSC project. FCP will keep the first timestamp interpretation in memory. The drawback of this workaround is that if the files go offline and you reconnect the timestamp interpretion is wrong.
You could try my BWF2XML which will put the BWAV into a QT-Wrapper including a user defined timecode rate – this way FCP handles the sound like a movie without picture but respects timecode and playrate.Regards

Or export the files as Aiff- that will strip the TC off.
Remember that while there maybe TC on your file, audio in measured in feet and inches or just length of time- there is NO FRAMES in audio.

But that’s what he wants to keep.“Remember that while there maybe TC on your file, audio in measured in feet and inches or just length of time- there is NO FRAMES in audio.”
There is no TC in BWAV file, there is a time stamp, which can be used to show up as SMPTE time code. Audio is measured in samples per second. With applications like QuickTime an audio frame is a second, with other applications a frame might be a sample.Andreas

Thanks for you answers. A version of the first work around did end up working.
It was essential for me to keep the “timecode” attached to the audio – in order to sync with the TC slate on camera.
just creating a new project did not work. i had to change the easy setup to NTSC DV @ 24fps. then load a piece of non-60p footage in the viewer in order to change the viewer timebase – i loaded a DV NTSC clip. then i imported the audio files. they then would play back at 24fps.
I then dragged them over to my 720p60 project and did my dailies sync.
what a headache. i miss the avid actually giving you obtions with the material you import. you can select what frame rate you like to import audio in the avid.
maybe digital heaven can hook this up.
thanks all

Mustafa,
Good to hear the first workaround worked some.
The Avid wouldn’t work with that kind of recording/setup as well as it also – same as FCP – relies on the sampling rate.
In both cases you can either change the sampling rate or do a fake for that.
My BWF2XML does it for years now when you work with FCP.Andreas
