Tip #75: Don't forget the bonus audio commentary!

By Dan Parkes (Director)

It has become a reasonably recent phenomena: the indepth audio commentary with cast and crew explaining as you watch the film how and what went into making it. Apparantly the very first audio commentary was on the 1984 laserdisc version of the original "King Kong" movie, with film historian Ronald Haver. Then later in 1997 the DVD version of the film "Contact" contained a bonus audio commentary with cast and crew which at the time was considered a gimmick to show off the capacity of new DVD technology. Now it is almost expected on DVDs and Blu-Ray, with most cast and crew happy to provide one, although directors Woody Allen and Steven Spielberg have yet to record a commentary believing a film should speak for itself.

While often the source of parodies and used for entertainment value, audio commentaries can serve a very useful purpose -allowing behind-the-scenes glimpses and filmmaking tips as the scene unfolds before your eyes. No doubt there has been a lot of thought and hard work that has gone into the production and this can also be an occasion in which to point out possibly overlooked work done by cast and crew. Maybe there is an unknown backstory or message behind a piece of dialogue or a production design decision that can be highlighted.

The recording of an audio commentary uses essentially the same tips as outlined in the previous two blogs on ADR (http://bit.ly/ADRtips) and Voice Over (http://bit.ly/voiceovertips). But here are some extra things to think about:

1. Before recording your commentary think of as many cast and crew who might want to be involved
2. Prepare beforehand by making notes of things you don't want to forget to mention
3. If there is going to be more than one person speaking decide beforehand of any particular scene they might want to speak about so you can co-ordinate it.
   
4. Have a method of syncing your audio commentary in post -using visual or audio cues at the beginning or end of the record session.
   
5. During playback make sure the commentators are wearing headphones to listen to the film itself at low volume
6. Commentaries do not have to be one hundred percent of the time -allow occassion for the original film audio to be heard.
   
7. Once you have finished recording your commentary it may need to be edited (to remove mistakes etc)
8. You will need to mix it with the original film's audio, with film's audio very low in the background but if there are moments of no commentary then bring it back up to almost full volume.
9. Add it is a separate track on the DVD that can be selected via a DVD menu option.

Tip #72: ADR - Avoid Dialogue Replacement

By Dan Parkes (Director)

ADR stands for "Automated Dialogue Replacement" and is the dubbing or re-recording of dialogue during post-production. Apparently in the UK it is called "post-synchronisation" or "post-sync".

This process is normally required due to technical issues such as poor on-location sound or interference. It can sometimes also be a creative choice -adding extra dialogue to make a scene make more sense. Or sometimes for creating different versions due to classification issues. Samuel L. Jackson famously had his key piece of dialogue from "Snakes on a Plane" rerecorded to replace the offensive language resulting in the dubbed version in he which says "monkey fighting snakes on this Monday to Friday plane"!

Sometimes up to a third or more of film can end up being rerecorded via ADR. However some directors such as Chris Nolan are well known for insisting on using on-location sound only, as quite often ADR -despite the best recordings- never rings true. So it certainly is best to avoid if at all possible.

ADR sessions mostly take place in a recording studio with the original actor watching a looped playback of the shot and then trying to recreate the necessary dialogue. For Ambleton Delight we created a similar process, although it was recorded in a living room. Here are some tips we learned along the way....

1. It really must be a last resort -despite the best efforts it will never match the real thing! Get it right on location as much as possible.
2. Don't just record the word or sentence as it most likely will be too difficult to match the feel of the original dialogue. Record the entire scene or as much of it as possible, to ensure audio continuity.
3. Treat ADR the same as when directing actors on set -give as much or as little direction, back-story, motivation as required.
4. Have the actor move around to imitate the body positions on the screen -especially if it involves walking, running or jumping, as this affects the tone and breathing
5. Use the same or as similar microphones as was used to record the original dialogue. Don't use a voice over microphone unless you need that effect.
6. If recording in a non-studio location be aware of acoustics and reverb and try to match or simulate what the original environment was like.
7. Provide a visual reference -a TV monitor or laptop. Beware that some TVs and laptops make high frequency noise that could affect the recording
8. Loop the scene, with both video and audio continually repeating for at least three times, then the fourth is silent allowing the actor to fill in the audio.
9. Have a visual or audio cue so the actor knows when the looping piece begins so they can time when to start.
10. Do it in small sections. Don't expect an actor to be able to match precise mouth movements over several sentences. But balance this with the need for momentum and being "in-character".
    
11. Not every word has to be exactly in-sync. Some timing can be assisted through audio editing -but of course better to get it as close as you can during the ADR session.
