Yesterday I posted an audio capture test with my GH2 using three different methods:
1. Rode Videomic
2. Zoom H4n
3. Audio Technica 835b Shotgun mike into H4n
I asked for feedback and I got some very helpful advice and suggestions.
Basically I realized that the Rode mic is probably the least favorable option. It might work better if you can get it closer to the subject, but then you'd have to use an extension cable and from what I understand, the 1/8" cables start to degrade signal at about 10 feet. Sooooo... I took that one out of the equation for now.
I also found some information about the Zoom that stated that when used in conjunction with a DSLR, it would be beneficial to set the line/headphone output level to 55. Yesterdays test was set at 70 so that might have been one of the reasons that the audio was a little noisier than I would have liked. The H4n is still sitting on top of the hot shoe so the distance is the same as yesterday, but I think it really does sound better.
I also recieved some feedback about mic placement yesterday so I when testing the shotgun mic, I did my best to get it as close to me as I could while keeping it out of the frame. I closed the distance by about half, going from 5 ft to just under 3 feet. Again, I think that this, along with changing the output settings on the H4n gave me a better sounding test.
I had forgotten about the wired lav mics that I have. They are really cheap Audio Technica ATR3350's but I figured I would throw one into the mix as well. I think it does a great job at isolating my voice, but all the brightness that was present with both the H4n and the Shotgun mic seems to have disappeared.
Again, any observations, feedback, advice or criticism is appreciated. I'm certain that all the "sound" people out there are cringing at these tests, but this is the only way I'm going to learn.
Thanks again for watching!
