Recording Ambient sound
In film making ambient sound recording is the recording of atmospheric or background noise. Fundimentaly ambient sound is any sound that is naturally created by the environment of a clip for example, wind, sounds of ocean, birds etc.
When making a film a sound recorder will often record 30 seconds of ambient sound. This means they ask everyone to be silent and just record what is there anyway. Room tone can be recorded in this way to help out the sound editor. it gives a basic sound that the room has which could be from anything, for example machinery. This gives the editor a background slate to work with so he can add dialog and other sounds over the top of it.
Recording sound on location is often preferred by sound recorders, This is because it is easier to record the sounds that are there and then tweak them later if needed. The sounds that are recorded on location are more unique than sounds found in a sound library.
In the film the Hunger Games ambient noise was recorded in a jungle and used 4 mics in 2 pairs in each pair each mic is set up facing in opposite directions. Then the other pair was placed around 50 meters away. This achieved all around sound recording more the best quality recording to create an immersive experience. Panning through speakers used when editing to enhance the immersive surrounding effect.
Recording Dialog
Recording dialog can often be difficult because it is not as simple as recording with the mic on the camera a lot of the time. This is because of factors like how far away the subject is. The environment conditions (e.g wind) can distort the sound that is recorded from a camera. Ultra directional microphones are used for exterior shots. Directional mics are used for interior locations. It is important to place the microphone close the the actors mouth so it is loader than the background noise so the dialog is clear.
Looping also known as Automated dialogue replacement (ADR) Is the process of re-recording dialog from the original actors. This is done when the quality of the original recorded piece of dialog is not suitable for the final cut. This is usually because the dialog is difficult to understand because of other external noises, for example wind or animals in the background. Sound editors will look through clips that have been shot and choice which ones need re-recording. An actor will watch the original clip and try to re-create the dialog, but it will be recorded in a sound studio where optimum sound recording can be achieved. Hard cuts are usually not advised because of the clarity of the dialog can be compromised by ambient and background noises.

Ambient noise is important while shooting conversation scene because it is likely that shot and position of the camera will need to be changed, especially if you only have one camera to record with. This means cutting between shots which entails finishing a clip and moving the camera. Because cutting to the next shot will take time it offers a continuity problem. It is possible the ambient noise is not continuous so there can be noticeable differences between the shots, For example the sound of traffic approaching, getting loader. The shot will be cut and then by the time the next shot is recorded the traffic noise will have become loader than it should be in real time.
