My Workflow for making BWAV's from Final Cut
on Jun 27, 2013 at 5:36:55 pm

Since it doesn't export BWAV's, and I couldn't find any free plugins to do it, I came up with this...

Thinks you will need are
1. ffmpeg I installed mine with macports.
2. Wave Agent from Sound Devices. It is free http://www.sounddevices.com/products/waveagent/

I made a script that will convert aif to wav using ffmpeg, and then delete the aif. I saved it to /bin/aif2wav. Don't forget to do a "sudo chmod +x /bin/aif2wav" to make it executable

Here is the script
#!/bin/sh
for i in "$@";
do
if [ ${i: -4} == ".aif" ] ; then
echo "Converting $i to ${i%.aif}.wav"
ffmpeg -i "$i" -acodec pcm_s24le "${i%.aif}".wav && rm "$i"
elif [ ${i: -5} == ".aiff" ] ; then
echo "Converting $i to ${i%.aiff}.wav"
ffmpeg -i "$i" -acodec pcm_s24le "${i%.aiff}".wav && rm "$i"
elif [ ${i: -4} == ".AIF" ] ; then
echo "Converting $i to ${i%.AIF}.wav"
ffmpeg -i "$i" -acodec pcm_s24le "${i%.AIF}".wav && rm "$i"
elif [ ${i: -5} == ".AIFF" ] ; then
echo "Converting $i to ${i%.AIFF}.wav"
ffmpeg -i "$i" -acodec pcm_s24le "${i%.AIFF}".wav && rm "$i"
else
echo "$i is not an .aif file"
fi

done



First, export your timeline as 24bit aif's, then open the terminal. If you made your script, and saved it to /bin/aif2wav, then all you will need to do is type in "aif2wav " and then drag all your aif's to the terminal, and press enter. You will see it quickly process them, and you will be left with wav's instead of the aif's. It will only delete the aif's if the conversion was successful.

Now open Wave Agent, and drag all your wav's to the window. In Wave Agent, set your frame rate, and starting timecode, then save them.

Then rename them to stems.

I also wrote a script for this
I had a 10 track timeline for delivery. 1&2 are LT,RT, 3&4 are M&E LT,RT, and then 5.1. So I made this script. It will handle if 1&2, 3&4 are set as mono tracks, or stereo. I saved it as "/bin/renmas"
#!/bin/sh
rename s/_1-2.wav/-01 Full Mix-(LT RT).wav/ *
rename s/_1.wav/-01 Full Mix-(Left Total).wav/ *
rename s/_2.wav/-02 Full Mix-(Right Total).wav/ *
rename s/_3.wav/-03 M&E-(Left Total).wav/ *
rename s/_3-4.wav/-03 M&E-(LT RT).wav/ *
rename s/_4.wav/-04 M&E-(Right Total).wav/ *
rename s/_5.wav/-05(Left).wav/ *
rename s/_6.wav/-06(Right).wav/ *
rename s/_7.wav/-07(Center).wav/ *
rename s/_8.wav/-08(LFE).wav/ *
rename s/_9.wav/-09(Left Surround).wav/ *
rename s/_10.wav/-10(Right Surround).wav/ *


So in the terminal, i type in "cd " then drag the folder from finder where my wav's are, then press return.
then I just type "masren" and return, and boom, the stems are all renamed, and timed with my timeline.

i'll confess i don't understand a lot of that!

but you could save yourself a step and export as WAVE from FCP.
it's an option when you export with quicktime conversion.

pretty impressive....too bad you can't hack into FCP7 and make changes and cool updates and then sell it. Just a thought.
