Camcorder Audio Settings for Editing in Final Cut

As discussed in the Section “Choosing Audio File Sample Rate and Bit Depth” on Page 212 in the Final Cut Express User Manual, Consumer mini-DV camcorders can record four channels of audio using 32 kHz/12-bit audio settings for sample rate and bit depth. After reading this, I checked my Panasonic PV-GS500 and sure enough, this is the default setting on that camcorder as well, i.e., all my previous footing was recorded with that setting.

According to the FCE user manual this setting is not recommended for most productions. It is better to use the standard 48 kHz/16-bit setting commonly used by DV, HDV, and DVD.

2008-07-13 Update: Putting it to use
It’s been long since I posted this, but two weeks ago I finally had a chance to make use of this tip. We went for our annual summer vacation, and I remembered to set my camcorder to 16 bit audio setting prior to recording. Since most of the recoding was city and landscapes it hardly makes a difference.

Now that I am importing into FCE for the first time, I had a hard time finding the right Easy Setup. Since I recoded in 16:9 I had to choose an anamorphic setting. I read that some time ago and don’t find it too intuitive. One has to know that anamorphic and widescreen are synonymous. But the problem came with the audio sample rate. You can either choose “DV anamorphic 32kHz” or “DV anamorphic”.

Here, the 32 KHz is commonly paired with the 12 bit audio, and 16 bit audio is sampled at 48 kHz. But where was the 48 kHz. Turns out, that the “DV anamorphic” is the 48 kHz setting. because this is considered the standard, the sample rate is not specifically mentioned. Again, not very intuitive.

Better Sound with SnapzProX

When recording a screen movie, e.g., a software tutorial, with SnapzProX, you can choose to record a voice-over with either the built-in or an external microphone. The problem is that the sound quality is not very satisfying given that it is a straight recording. It would be better if you could filter that audio recording in real-time. The solution comes through Soundflower and Audio Hijack Pro. Continue reading

Home Recording Without Background Noise

I recently started getting into home-recording, primarily to do voice-overs on videos or to record screen tutorials for my parents. Of course I don’t have a quiet sound studio at my disposal, so my study has to do. When I turn off the radiator and close the door, it is actually pretty quiet except for the fan on my iMac. That plus background recording noise won’t go away and is quite distracting on plain voice recordings. Some searching online pointed me in the direction of using a noise gate filter: Continue reading
