I didn't say that. I said a visual reference alone was pretty much worthless. .../... Get a reference peak tone from your sound mixer. .../...It would be jolly lovely to have live VU's on the camera back, but they aren't an indication of the quality of the audio, only the strength of the signal. .../... If you are serious enough to care about any of this then I cannot accept that you would not want a way of hearing what your microphone and mixer is hearing.
Still don't agree. First of all, I have 15 years of experience recording concerts, so I am aware of what the IDEAL setup should be. But we're talking about all those events where you can't get a line from a mixing-console and you're working with an external mic, like the Rode stereo video mic. In that case, being able to monitor the audio level is a MUST. Sure, you can't judge the quality of the sound by looking at the dB meters, but at least you can make sure it doesn't clip, which means distortion, which in turn means NO QUALITY at all. So even with the ability of AGC being turned off, there is still a great risk of clipping, unless you can actually see on the screen what the audio levels are doing. So, I'd turn it around. 5% for being able to turn off AGC (with AGC on there is actually less chance of audio clipping) and 95% for being able to view the audio levels on screen.
