Personally ive not come across an audio mixer taht accepts embedded audio, however you can get Embedder/Deembedders that will pick out the audio from the embedded signal and pressent it to a mixer as AES/EBU of SPdif.

I dont know this camera or mic, but this may help.
1) Is input 2 a line level or mic level input. The mic will be outputting a miniscule voltage compared to a line level signal. Usually @40DB lower.
You need to investegate the differences between the inputs.2) Does the mic need phantom power. If youve got it on and the mic isnt phantomed then it may cause damage to the capsule. Is the mic generating its own power? Have you tried it into a different device to prove it works ok.

How come it took til post 7 on this one before the first mention of calibration as mentioned by Peter.
Surely METERS and Calibration are the answers.

Video is based on TIME (seconds) not “frames per second” like film.
EH!!
Video is based on SMPTE. 25 frames per second in the UK.
I say decide if this is a PAL or an NTSC project. If its shooting PAL but being edited NTSC then the audio will be tkd with the footage. If not then it is a pAL project and you should stay pal as the final master tape will be PAL. Then it can be transferred to NTSC once completed.

Ahh but John
“Another thought is if you can export each audio track from your edl as a wav”
They wont be able to access any handles this way! Why go to a sound dub at all if you deny sound guys the tools to do their job.
Then again as Frank says“Get another sound house. If they don’t know this, then they dont really know post sound. ”
Frank is right, and if they cant manage this simple function then they wont know what a handle is anyway.
I agree. Get a new post house. If they cant do this simple thing then I’d move on. This is like Macdonalds running out of chips. EH!!!!

Dubbing Mixer -
HI there
I think the comprehensive comments from Ty and John just about cover this one, but for my addition.1) If it is recorded, too hot, or clipped as a digital signal then all of the bits have become full. ie the digital datastream that is the audio instead of being 0’s and 1’s becomes all 1’s. This is where clipping occurrs and is one of the biggest negatives of the digital domain as the audible effect of clipping is far more objectionable to the ear than analogue tape saturation onset where the effect is gradual.
Like a ming vase dropped down the stairs, once its broken , it is broken and no amount of tape and glue will mend that audio.2) Re recording levels. The recordist ought to have laid down some tones from her mixer at the head. These were stated to be -20 Correctly. That represents a 1k tone = PPM 4. The audio then following ought to follow at @ +8DB so peaking at -12. There is still a good way before the audio hits clipping at the recorder stage. If the waveform displays show a flattening of peaks but there is no audible clipping, and the audio was passed in digitally, then Id suspect that a limiter either in the remote mixer, or some sort of on board camera AGC was responsible for the problem.
In general, if theres a recordist with an external mixer and tones etc are employed then there should be no need for AGC at camera stage.

which would you suggest, and website.
Needs to be genlocked
Video capture not important (probably sdi) but op PAL

Its like a cup of tea (well I am English)
Once youve put sugar in then all you can do is make another cup if its too sweet.If I had a pound for every time someone has called me with this sort of problem.
There is little you can do (although mixing in some music may distarct the ear a little) but be careful

personally if poss id suggest your own mic. if the pa mic goes unstable and howls then at lease the howl for you will just be ambient pick up and not the much worse direct feed.

Hi
NTFS drives (or at least mine were) are ok, however you may get an issue about the length of the name of the drive. mine was called “video and audio media” and had to be shortened.
Also be aware that if you export some files (mp3 included then there is a character limit of 32. If you exceed this then exporting an mpe from Digidesign will resutl in a massively longer file (about 1.5 mins of silence after a 30 second cue.Should be good to go though.
