K7 Low Video sound

Posted 17/12/2010 - 19:57 Link
Not that I am too bothered about the video but is it just my K7 that the video sound output volume is poor. When playing back video clips through the camera even with output level set at max the sound is very low. When played back through PC the quality is reasonable but the sound output is still very low. Pentax emailed me and suggested I use an external mic. I am unlikely to use video enough to justify buying external mic so has anyone else found a problem with built in mic.

Is there not a mic level control on the camera?

I have searched the menu and the manual and so far can only find that output volume can be adjusted.

That's a bit poor. There should at least be a gain control and an input level meter on the LCD.

How many bits is the AD convertor?

I'm a bit dim, whats the AD convertor?

Just ralised that AD is Analogue/Audio Digital but do you mean the in camera or PC AD and how do I check either?

How do I find out? I presume it's the in camera convertor you mean. How will that help by knowing this?

External mics cost less than £10. Why is this "too much"? Good ones are a little more expensive, yes, but still under a ton...

Well if it's 16bit you won't have to worry so much about keeping the level healthy. I can't see why it wouldn't be these days to be honest.

An extrenal mic would need to be more sensitive in order to provide more level otherwise you'd have to plug it into an external mic amp before plugging into the camera at line level.

It can get cumbersome unless you are seriously shooting movies.

It wouldn't have been difficult or costly for Pentax to have included an input gain control.

I didnt know I could get one for as little as that, I think I could just about afford that. I just hope it fixes the problem and its not a camera fault.

It's unlikely to be a fault.

Life's too short for cheap,("Buy Cheap = Buy Twice").
I bought a Rhode shotgun 'VideoMic' mostly for the Xacti camcorder, but great with the K-7, though I don't have any issue with the internal mic.

Ha ha yeah I'd be interested in one of those too! You could try one of these, but they're probably only a slight improvement on the internal mic:

Fake Sony Mic

Which you can hear here compared to the internal mic of a Kodak Zi8 video cam link

But you probably really need a good shotgun mic for proper sound quality with video.
