Investigation 2/23: Automated Dialog Replacement (ADR) Investigation

Looking back on the audio I have recorded for my next project, I have some fears that some of it might not be usable in my next film. If there is a scenario that a clip wouldn't be able to be used, I would have to find some way in order to correct this error. This led me to investigate the process of Automated Dialog Replacement (ADR).

ADR And How It Affects A Film

Automated Dialog Replacement is the process of re-recording spoken lines of dialogue following the original recording of a scene. Through this process, a better/cleaner recording can be created, which helps to improve the original quality of the scene. While ADR can significantly improve a scene, if done improperly, the audience could possibly notice that the characters within the scene are not actually speaking the audio that is being heard. An example of bad ADR can be seen in this scene from The Great Gatsby. In this scene, Leonardo DiCaprio's mouth does not appear to match the words that he is saying as well as his lines sounding as if they were recorded within a sound booth rather than on a car as the scene would suggest.

How To Record ADR

While ADR can be used to achieve better audio for a scene, it is important to attempt to record the best possible audio while shooting on set. To start recording ADR, you should begin by taking the footage of the scene that you would like to re-record and preparing it by looping it multiple times in the timeline. This will allow the actor who is re-recording their lines to analyze what the said, so that they may recreate it as close to the original as possible. After multiple attempts, you will likely have at least one recording that appears to fit with the original clip. By putting this new recording over top of the original clip, it may seem too "clean" sounding for the scene. In order to work around this, audio effects, music, and environmental sounds may be added to the scene which should hopefully help make the re-recorded audio seem less noticeable. This process can be repeated as many times as deemed necessary for each project. In this video, Hugh Jackman watches over footage from Logan in order to record ADR for the scene.

Investigation 3/1: The Tools Of Camera Stability

One of the most important aspects of cinematography that goes commonly unnoticed is having the camera steady. Even a slight amount of movement within a shot can pull the audience away from the film, so it is important to attempt to have shots. There are multiple different ways that you can use to stabilize your camera, some of which are more effective than others. Tripod Using a tripod is the easiest way to stabilize the camera while filming. By having three points of contact with the ground, a tripod keeps the camera extremely stable. The camera would likely only move due to very large movements on the ground or strong winds. The one downside to using a tripod is that it has to remain stationary. If the required shot involves moving around, a tripod can likely not be used. Overall, the tripod is the easiest, simplest, and cheapest way to keep your camera steady.

Investigation 2/21: Film VS Digital

Ever since the rise of digital cinema cameras over the past couple years, the debate of Film versus Digital has soared. All across the internet, you will see people argue over which is the superior format to use in order to produce a film. While there is not real answer as to which is the overall best format, both film and digital have their own strengths and weaknesses. Digital Digital has become the most popular format for the everyman. Phones and digital cameras can quickly take pictures and record them to digital memory for instant review. Recording with digital doesn't take any money out of your pocket other than the cost of the camera and recording media. If your shot doesn't look exactly like you wanted it, you can easily just delete the failed take and try again and again until things end up the right way. Since your digital photos and videos are essentially computer code, it is extremely easy to edit and manipulate them while having infinite flexibility to do so. Digit...
