HDV audio for broadcast?
IS anyone using the MPEG1 audio from the new Sony Z1 cameras as audio for broadcast? We are having big issues with our audio being compressed before we even get to sweeten it…..it hurts…really..

I’m not surprised the compressed audio on a HDV camera’s tapes isn’t very good… not much to do here, but do a record to a mini disk or dat or whatever instead of using the HDV camera’s audio in the future….would that be possible? FWIW, the audio is in an MP3 format on that camera, not MPEG 1… My film students are doing just that, and it working out OK, however you have to sync this audio of course manually….
Comon’ Panny get that 200 out there, you’re gonna sell a TON of them. HDV is a consumer format for sure…

Im pretty sure it is MPEG 1 layer 2 audio,and if im not mistaken, I thought MP3 was a form of MPEG compression on audio…..maybe Im confused…..

The compression for the audio on DVD is very slight, so I’d be guessing it’s more the fault of the mic pre-amp in the camera than the HDV audio itself.

HDV is MPEG 1 layer II. Minidisk is also data compressed. Dat is PCM. As a post sound studio we get rubbish on PCM and good recordings on MPEG.
Mic preamps, A/D conversion and above all a good quality microphone IN THE RIGHT PLACE (which is not on the camera!), are the issues to address. I have heard perfectly acceptable audio off the Sony Z1. The Sony PD150 sounds noisy with bad analog cirucuits going to PCM. So in my experience the Z1 is better, in spite of the MPEG compression. So if you stick a lousy lapel mic on a cheap radio transmitter into anything it will sound cheap.
And when it gets to broadcast, some think Dolby AC3 is OK. If only MPEG 1 layer II was the standard!
