Audio fine, but video slow

The problem is the microphone on the camera. The mic on the camera is for recording sound in more normal environments. The sound level on a typical concert is much higher than normal, and the mic on the camera just doesn't have what it takes to record sound at those levels.

One possible solution is to record the sound with a dedicated audio recording device, and combine the video and audio in your video editing software.

Look for a Menu then FPS (Frames per second) option.30 fps should solve your issue. sometimes in order to keep file size low the setting is slower causing this issue.Good Luck.

You will need to install a codec pack on your computer to resolve this problem. Download and install the codec pack from the link below and see if it resolves the issue.

Sounds like your computer is having trouble decoding the video. You might try a newer video playback program, such as VLC (http://www.videolan.org).

You can get the current version of all free Nikon software from their web site at http://support.nikontech.com/app/answers/detail/a_id/61

Use a card reader to upload your videos to a folder you create on your desktop.

Unlike later models, the L4 does not record any audio on its videos. You can add a soundtrack using video-editing software on a computer, but not on the camera itself.

Hello,

The Nikon Coolpix 4600 does not record any audio with the video.
This is surprising and not very useful.

The Coolpix 5600 does and the 4600 uses the same body, that is why it has microphone holes on the top.

Support on Windows ME for USB is poor. Your best shot is to go to the setup menu on the camera and select USB and then make sure it's set to "Mass Storage" and not "PTP". Then connect the camera.

That's because this camera records video only without audio, same as on the 3100.
