1Recording Sound for Video

Situation Practical 1 Use Technique

When filming video, the sound quality is often insufficient.

Using the R-44 allows you to record sound for video at a higher quality.

Here, we describe several recording tips on how to record sound for video.

1Advantages of Using the R-44 to Record Sound for Video

Using the R-44 to record sound for video has the following merits.

You should try using the R-44 with video filming.

•Better sound than recording with the video camera’s microphone Sampling rates up to 192 kHz are supported.

•You can record sounds difficult to record from the video camera location

Sounds that cannot be recorded by the video camera’s microphone can be picked up by the R-44. Sounds from another location can be recorded at the same time.

•You can record environmental sounds and spoken lines separately

•You can capture the actual ambience of the location, and use your computer to convert it to 5.1 channel surround You can set microphones in four locations and change their position freely to create more realistic sound.

Synching Video and Audio

It is difficult to synchronize the video and audio during the editing process. But, with a little ingenuity, you can synch them easily.

2 Applied Technique

Play a Baseline Sound and then Record

Clap your hands as the video filming begins as a signal to start recording.

By using this sound as a baseline, you can easily synch the timing between video and audio during editing.

Recording Settings

If the audio recorded for video will be used together with the video material to produce a DVD, we recommend the following settings.

Also, you should use the Pre Recording settings to prevent missing a recording.

Input Select	Analog	Sets the mode to record with an external microphone
Rec Freq.	48 kHz	Use 48 kHz if ultimately you are making a DVD match to video,
Rec Bit	16 bit	or if you are saving with high-quality sound, recording with
		96 kHz makes conversion easier later
Rec Mode	STEREO × 2 Setting to use two stereo system (2 channels) to record
Pre Recording	10 sec	Record ten seconds ahead so you don’t miss anything
Project Name	Name	To help distinguish your projects, it’s a good idea to give each
		scene its own unique project name
