Descent – Multi-film Audio – GB AUP 3rd Year SEM B

RESEARCH – Dub Mixing to R128

13421070 / May 6, 2016May 9, 2016 / Research - Film Audio, Role – Dub Mixer

(Outcomes – IN2 + GR3)

Part of a dub mixer’s job is to deliver mixes of programs to particular technical specifications. In the case of programs for broadcast, the current European standard is EBU R128, a set of rules regarding loudness normalisation and permitted strength of audio signals. As part of another module this semester we interviewed staff at Soho Square Studios, one of whom explained to us that knowledge of working to this standard is very much sought after in the post-production industry.

The dub mix I carried out for our project last term conformed to the BBC’s guidelines for production. This term, I’ve suggested to our directors that all our output should conform to the newer R128 broadcast standards – they have no particular requirements, so this is as good a choice as any.

The essential difference with R128 mixing is that it requires reference to the overall loudness of the piece over it’s entire length as an average, where BBC guidelines I have employed previously simply control the audio peak levels within the program regardless of it’s average loudness. The changes were wrought mainly to deal with advertisers using the perception of loudness (through compression, and rather than the mathematical loudness inherent in the audio) to create irritating volume changes relative to a given program. Practically, it enables higher highs and lower lows across the course of the program, but controls the volume across the course of the bulk of the output.

EBU R128 changes the unit of measurement of mixing from decibel or PPM to loudness unit, and requires that the mixer bring the average loudness of the piece in between 22 and 24LU by it’s completion. It also measures peaks within the audio waveform much as with the BBC method, and requires that none of these surpass 1.0 on the true peak scale. There is also a loudness range requirement which must not exceed 95%. [IN2]

I purchased a metering plugin which is R128 compliant, and ran the mix I created last term through it for reference –

As we can see, this piece would not comply with R128 as it too quiet on average by 4.4LU even though peaks etc are within range.

Having completed the mix of Descent to the previous BBC guidelines, results were –

DESCENT BBC MIX

This was both too quiet on average (27.1), and contained a couple of sharp peaks (0.3) which are too aggressive for broadcast. I remixed the latter and ran another mix –

As you can see, this mix is *only just* within the compliance threshold for average loudness, though the peaks are now well within the line. I deemed this sufficient as I was extremely pressed for time by this point.

Working to R128 is industry standard for broadcast in the UK and as such is an extremely useful to have learned – it was referred to during an interview with a professional audio engineer for another module as one of the most important things to know about – and it’s interesting from the perspective of the mix process, since it enables a less slavish monitoring of PPM metering and a freedom to push big sounds more aggressively for impact. Descent was not really the film on which to demonstrate this last technique since it is one which uses realism and more subtle light and shade, but I think the process will inform future sci-fi work I undertake, if nothing else.

DESCENT – Final Appraisal

(Outcomes – GR 1,2,3,4,5 + IN1 + PER4)

Having completed the final mix of Descent, this post will comprise an appraisal of issues with the artifact as it stands.

The main issue was with dialogue during editing and premix, with the close shot scenes around the kitchen table particularly problematic as the room they took place in has the most horrendous honky reverb which acted like the classic tiled bathroom reverb on all the dialogue, worsening as the actor’s projected more. This reverb was largely removed with Izotope RX, and some EQ’s applied to the dialogue at the same time. However, the dialogue takes were presumably not tested together prior to the mix phase (dialogue edit and mix were carried out by two different people), where it was discovered that any dialogue which is both boomed and collected from a radio mic on the same actor is close to 180 degrees out of phase, obviously closer to this amount relative to the shot, as the boom was able to be placed closer to the actor.

You can clearly see the reversed phase in the photograph above. I can surmise that the outputs on the university radio mics and the MKH boom microphones are wired to opposite polarities, and this wouldn’t have been noticed on set because the master mix I use when monitoring the incoming audio was always split into stereo, with one side comprising radio mics and the other comprising the boom and other mics. When these were mixed together in the scenes however, noticable phase cancellation occurs. The combination of this and the processing in RX left the dialogue lacking body, and dangerously thin in places, whilst attempts to correct this using channel EQ consumed a large amount of time in mix. This finally necessitated the recutting of the main dialogue-heavy kitchen scenes after the first pass mix had been completed as we collectively felt it simply wasn’t up to standard, and the dialogue is still not perfect in the finished version. [GR3,5,IN1]

The mixture of production audio and foley is also a fine art and Descent uses a lot of audio from the set for the busier scenes. It was not always possible to perfectly match the perspectives of the actual set with the sounds we created in foley, and the artificial reverbs and different room tones are occasionally noticeable.

Moving on to the effects of our collaboration on the production of Descent, this particular film was very much a group effort. The script and planning phase benefited from a great deal of input from other team members, I had the choice of two composers for the project and was able to go with the one whose approach best suited the director. In post, both foley and dialogue editing tasks were split to other group members, and the final mix was heavily collectively appraised, overruling my preference and leading to an 11th hour dialogue remix which improved the issues described above. This film would definitely have been worse without the group approach, and my own time would have been less efficiently spent for certain. [GR1, PER4]

In terms of feedback on the production, I sent the following to the director and producer:

“The core team for Descent were exceptional, transcending the standard of many of the student productions with which I’ve become acquainted this year. All communication was prompt, consistent and professionally managed, production plans and details were communicated with plenty of time, and included opportunities for audio recces of the set and a sensible regime of pre-production meetings and test shoots. The production team engaged early with the process of designing the audio dimension of the film and were creative and professional in the way ideas and plans were formed, communicated and allowed to evolve.

On set, the extended production team worked cohesively and largely to a strict schedule with little apparent stress or evidence of issues. Location audio work was a pleasure to manage from my perspective. I strongly recommend any member of the team for roles in future productions and would be pleased to find myself working alongside any of them again in the future.”

In turn, we received glowing feedback from them for the service, which can be viewed in it’s entirety here. [GR1,3,4,5 + IN1 + PER4]

At 17 and a half minutes, the piece is reasonably long for a short student film created in a single term, and I’m proud of managing to sustain the work of carrying this film’s audio through from inception to completion. Whilst it still has a couple of rough edges, I believe it stands up as the first piece of film audio work worthy of portfolio use. One major piece of practical information I have learned from my work here is always monitor and mix your location in mono. The film editors who receive the raw audio before sending back the compiled lists do not benefit from stereo, and monoing at either point would have allowed me to pick up the phase issues on-set and saved time in post.

P + P -DESCENT: The Radio Scene

13421070 / May 5, 2016May 9, 2016 / Descent Contrib., Individual Reflection, Process Management

(Outcomes – GR5, IN1, PER3)

This post demonstrates the process of liasing with Descent’s director, and an example of how research into the film Hannibal informed Descent’s audio practically.

The director requested a radio be playing from the first kitchen scene very early on, and provided a list of popular songs that might be played for this cue which they felt signified the story of the film prior to the arrival of the script. We immediately advised them against trying to get clearance for popular songs based on our experiences last term, a discussion which didn’t really lead anywhere conclusive.

It was resurrected upon our receipt of the script, however. A number of music cues had already been agreed by this time but the director decided that we should run the diagetic radio cue from the beginning of the first kitchen scene to the end of the final one, which comprises about 80% of the run time of the film and compromised a number of the music cues we’d agreed and which had already been roughly composed.

We’d also pointed out that the picture should refer at some point to the source of the diagetic music – with a music device in the background for example – and that one of the characters would presumably at some point have to the have the opportunity to turn it on and off, and that the requested length of the cue wasn’t conducive to the latter, since the music was expected to drop out somewhere around an active scene for the characters. The length issue was finally solved when we were given the choice of deciding where the cue should drop out after pointing out how badly having this cue in could impact the rest of the score for the piece and, whilst seeking further guidance for the device, the director requested we make the music function like the following scene from Hannibal – [IN1 + GR5]

;

The score here shifts from diagetic piano music to the sinister synth based stuff fairly seamlessly. I passed this scene to the composer, and our final attempt at it can be seen below (please skip to 4:00 if the youtube embed below starts at 0:00 on your browser) –

The editor also chose not to refer to any kind of visual source for the music and, whilst I had initially felt this would be problematic, watching the outcome I believe it works fine. I’m aware that I can be slavishly insistent on realism at times with devices like this, but have learned that this is not always necessary as long as the visual scene (in this case, an obviously romantic dinner) is set strongly enough. Audiences can be relied upon to ignore minor incongruities in this situation. [PER3]

DESCENT – Sound Design + Feedback Process

13421070 / May 5, 2016May 9, 2016 / Descent Contrib., Individual Reflection, Planning, Process Management

(Outcomes – IN1, GR1, GR4, PER1)

In my capacity as the supervisor for OG Productions managing the film Descent, I’d solicited a list of ideas from the films director about the audio dimension within a week of agreeing the services we would be providing for the film. These were perfunctory in terms of specific links to the film, as would be expected as this stage since no script or storyboard had been completed, but were detailed in terms of reference points from other films. There was also a list of potential choices of diegetic source music tracks for a song playing from a radio at some point in the potential script, as a reference point. At first glance many of these were highly unlikely to be clearable in the context of the film as the film-makers were keeping their options open and requested we clear any material required for the soundtrack for use at film-festivals and for online use in portfolio. [IN1]

Upon arrival of a script and storyboard for Descent some weeks later, the audio team read through the script together in round-table fashion. I’d insisted on this process for OG Audio’s three longer films as it was obvious that our collaborative approach to work could very easily have translated into creative isolation for the supervisors responsible for the less ‘desirable’ films (for example, as some scripts appeared stronger than others, or because of genre preferences for the team) in the pre-production stages. In the case of Descent the ideas session gave rise to two different directions for music for the film, a minimalist approach from Matt and a much more aggressive underscore heavy idea from Alice though with plenty of crossover in terms of pallette and timbre between the two – I felt Alice’s choices were likely better for the film initially. Potential recurrent motifs and key scenes for audio were isolated and a scratch sound-plan with an overview of these ideas created. [IN1 + GR1 + GR4]

I was keen to solicit as much feedback as possible throughout the process of liason with the film group, so this plan was then cross-referenced with the director on a page by page basis at the set-recce and meeting pictured above, enabling me to tweak the plan more to their liking with almost everybody involved in the production present. For example, my preference for a relatively music heavy film was overturned as the director clearly preferred the subtler, more minimal approach to the music design as we described it, and as such I asked Matt to provide the score and music for the film. The meeting also yielded useful discussion on several overall balance issues within the sound design of the piece, such as how far we should be ‘borrowing’ from horror and thriller genres influencing the piece, tropes which were initially suggested by the original reference material provided by the director – It’s more thriller than horror, but only just. [GR4]

This session basically concluded formal pre-production on sound design, though some later correspondence and a second meeting were required to finalise specific elements and introduce a late addition to a scene suggested by the director in the form of an inner monologue which wasn’t present in the script, and which required specific recording time. This became one of several bones of contention in the sound design throughout, the other being scene 3’s radio music cue.

This process enabled me to piece together a master document of specific devices and the general audio arc drawn from the rough sound plan formed the basis for any team members working on the audio for the film in post, and which can be referred to by the director throughout the production.

However, no battle-plan survives contact with production and elements of this sound-script were dropped or changed in reference to the pictures as they arrived, and as the film moved into post I kept up the informal opportunities for the director to feedback on our work as they would often pop in for a listen whilst we were working on the piece. I concluded the feedback process with one more formal meet with the production team post picture-lock and after dialogue editing, foley and composition were complete but prior to mixing, roughly a week before deadline. I also requested our formal feedback at this time by way of the online feedback form I constructed for our use – The responses for Descent can be seen here – which was universally positive, best summed up in the response to an open question which I’ve lifted as a testimonial ‘…the team are extremely professional and skilled at what they do, they have the ability to transform a simple idea into something exceptional.’ [IN1]

Reflecting on this process, it was a good example of a creative collaboration between this audio team, and the director and her team. Ideas, approaches and plans were constantly being tabled, revised, filtered and discarded and the design input was spread roughly as evenly as the workload. The music decision was the main learning aspect for me, since having two composers working on the project in preproduction enabled me to present to vastly distinct approaches to the project in the early stages in some detail, thus prompting the director to a stronger vision of her musical requirements.
