I have a PC7 (Sony) DV camcorder which works OK for shoot ing family videos, but I have a problem with the noise generated from the motor which is always captured to the audio track and is difficult to remove. What can I do with it? External Mic? apply plug-in filter during editing on computer?(posted 8328 days ago)Besides, what kind of accessory do I need for my PC7 to enhance its video and audio quality. Many Thanks!
