soundtrack pro 3 offers the option to export a multirack project in aaf format. as far as good. but I can't find the option to choose in which bit depth the files are rendered. I need a bit depth in 24 bit.
anyone know how to choose the bit depth?
I tried to change the prject properties in 24 bit, open a new project and copying all files in the new rack, then export to aaf. rendered files still in 16 bit.
thank you in advance.

Does AAF even support 24 bit? Have you tried another format just to see the options available?
thank you for your quick answer.
Honestly I don't know if AAF supports 24bit. I believed that is an industrial standard.
however I solved my problem in an other way, I exported every single track as a single file in 24 bit. so my sound engineer reassembles them in his sound application.
Alphabet soup!!
Do you mean AIF (AIFF)? AAF would be more about exporting the project rather than the actual files, so i don't think there would be any conversion involved.
When I answered, I was thinking of AAC export, which does not seem to support 24 bit. AIF, on the other hand would be a pro file format that a sound engineer would use and that does support 24 bit.
thanks for your reply,
no, i mean exporting the hole multirack project via AAF. By doing this, using export as AAF, stp generates single files for each clip in the stp timeline. but, all this new generated files are all rendered in 16bit depth, even the source files was originally in 24bit depth. they all got down converted.
my sound engineer asked the 24 bit depth for the further mixing session.
so as mentioned above, I exported every track as a single aiff file. in this case the 24bit option work without problems.
my last question, just for understanding reason. does stp not allow an aaf export in 24bit depth? by using in FCP the option audio to OMF, there is a option to choose the bit depth and the sampling rate, why not in STP?
Ahhh! Go to STP preferences.
On the project tab, you will find a selection for export bit depth. Choose 16 or 24.
thank you paul,
I tried this option before I wrote the first post. Still the same result. the rendered sound files remains in 16 bit. I tried with a new test project. export as AAF, the checkbox 24bit activated and reimport the AAF in STP. the audio files are down scaled to 16bit.
anyway thank you kindly for your replies. as far a I see, the better opion by further postproduction is whether assembling the audio track in FCP and export them via OMF or by remaining in STP export the hole track at once.
OK. But my curiosity continues, if you don't mind. I haven't had occasion to use STP for AAF export before, except in tests, but my logic is telling me (logic with a small 'l' , not Logic the software pgm) that AAF is exporting the project and either referencing the media or packaging it for export. If it is referencing the media, then it has no business transcoding it. If it is packaging the media by duplicating it, perhaps it does not up-rez it. If the original material was 16bit, it will not magically get more 'resolution', just as an SD video does not become HD just because I transcode it to 1080i.
That being said, perhaps i should ask: "Was the orig. material 24bit?"
hello paul.
the answer is yes. the source files was in 24bit and 96khz. recorder with an sound device 722 hard drive recorder.
stp does not referencing the material, the material was duplicated and packed in a new folder by giving them strange names like "..._channel_005_6BB7FADA-3688-484C-84A9-DDE4E05C6A6F.aif"
thank you for your curiosity, this is the way to solve troubles.
