DP 44-audio, movie 48-audio, best practice ?

[Klaus]

I have to underlay my live multitrack recordings / mix to a movie, that has 48k camera audio, but I'm coming from audio - only 44k land, and the projects are all 44k/24b.
Can I edit my audio / start times with the 44k project, and export 'synced' as 48k to the movie ?
Sorry for the beginners question, but thanks

Best

Anyone ?
The export soundbites / movie doesn't work ( DP 7.24, SL, QT 7.6.6 ). I would like to use a longer sound file and add black frames as selectable during export. The resulting movie can't be read by QT 7...
Adding sound from the movie to the sequence doesn't work too ...
DP is 44k, movie is 48k
Appreciate help

Thanks

Do a sample rate conversion on the audio project to 48k and work at that rate.

HC is correct. If you start going down the path of trying to stitch together different sample rates you will run into sync and maybe even pitch problems (playback speeds). I just set my system to 48k/24bit for all my projects. If I need a 44.1k or MP3, etc., I'll bounce it. We're not talking a big increase in disk consumption going from 44 to 48. Besides, if anything in any project ever needs to get used with picture, the files are ready to go. Thinly down side is DP will not create CDs from a 48k project (unless they fixed that and I don't believe they have). That's not a great loss as DP has not been reliable or intuitive when it comes to CD creation anyway. Other than that, there is not real reason to stay at 44k unless you know you'll never work to picture again - in which case a euthanasia app may be a good option. LOL.

The resulting 'temp movie file.mov' isn't readable by QT 7...
Everything converted to 48k, and still no luck,
searching Motunation , and it seems to be kaput in DP 8, could it be
DP 7.24 and QT 7 is a no go to ?
( the orig. QT install of SL is still present... )

Strange. I bounce 48k movies all the time and QT 7.6.6 reads them just fine.

[MIDI Life Crisis]

I'm not in DP 7 but it did allow for export options in movies (DP8 killed that). You might try a "referenced" movie and then from QT export that. I'm not really sure what's going on there.

[Klaus]

DP can also bounce to movie... but then I get

edit :
Mas, 1 Error reported by quicktime export plugin ( -2015 )

Pfhhhhmm

I tried also choosing the 48k soundbite > export > to movie >referenced,
unreadable
The movie I received is H.264/AAC 48k
QT export plug is 2.6

QT 7.5 pro saving the movie ( mp4 that I received ) results in
...could not be saved, movie contains an incorrect time value.
The mp4 came from a Mac / Adobe rig

I wonder if this is just movies from a specific person/company or ALL movies? When I have situations like this I'll put the movie in QT and export it as a stand alone for use in DP. This is also important when I get a hi-res film but don't want to continually export hi-res out of DP. BTD (movies) was so much easier before MOTU dropped the QT export options. Referenced movies take up so much less space. Now each bounce hogs the drive space. Tres annoying.

Made a self containing movie in QT 7.5 ( PPC ) and it worked...
QT 7.6.6 made a self containing movie with no video visible...
DP 7.24 export options are labeled (PPC) and the result is BigEndian.
My guess is Apple changed stuff... and MotU wouldn't follow...
If they drop Mac, it's Apple causing it, and not MotU running a different rail on their own...

What a nightmare, sometimes...

Thanks anyway

and best regards

Recap :
If I work in DP 7.24 / 44k, and play a movie with 48k audio, DP seems to play the movie audio with the same speed / pitch as DP audio.
Thus, bounced audio in 44k, and exported as 48k will not exhibit clock / speed issues for
the film guys, or will it ?

As the subject says, I'm trying to figure out *my* best practice, since if I don't have to convert DP projects from 44k > 48k, I'd prefer

Thanks a lot

and best regards

I wouldn't. I'd import the audio and let DP convert it but I'd NEVER work in 44.1 on a project for picture.
