Re: [Frameworks] optical soundtrack generator?

[Eric Theise]

Interesting thread.

Scott (Stark), the Kapotski "Optical Sound generator" you launched the
thread with (http://www.kapotski.be/wp/?p=204) looks to be a simple circuit
that maps values of light-to-dark to frequency. A bit like a theremin but
for light instead of proximity.

(When I was a kid I built circuits like that from scratch using electronic
components (Chicago alert: probably purchased from Allied Electronics on
Western Av (https://chicagology.com/silentmovies/alliedradio/)). I remember
being fascinated by the "electric eye" that opened the doors of a grocery
store on Foster Av, just east of Damen.)

Sandy McLennan's recommendation of Matt McWilliams' soundtrack.optical
looks promising. It doesn't seem as if it's under heavy development  – only
one code commit this year, from January – but it seems quite far along in
its functionality. You say you're unfamiliar with Processing; it's an
environment developed in Java that was designed to be artist-friendly. Been
around for nearly 20 years and it's well-documented and has an active user
base. Roughly speaking, programs are called sketches and the environment
compiles these sketches before displaying results. It's easy to get started
with, there are many tutorials, and McWilliams directs you to one (
https://github.com/processing/processing/wiki/How-to-Install-a-Contributed-Library).
The software I initially used to do the frame-by-frame analysis of the
colors in your To Love or To Die was adapted from a Processing sketch. Even
if you end up not using soundtrack.optical you'd benefit from studying the
code to see what it's doing.

I ended up writing a Python program to analyze To Love or To Die; Python is
best suited to your desire to use a scripting language. I used OpenCV
because I was doing cluster analysis on video attributes but a quick search
suggests that Python libraries like pyAudioAnalysis (
https://github.com/tyiannak/pyAudioAnalysis/) or scikit-sound (
http://work.thaslwanter.at/sksound/html/) would be relevant – or overkill –
to the audio import and analysis aspects of your project. One of Python's
SVG writers, or something in Matplotlib, might be appropriate in generating
your output although, again, they might be overkill.

Personally, I'd start by installing soundtrack.optical and scaling its
output for use with 35mm frames.

Re: [Frameworks] optical soundtrack generator?

[Scott Dorsey]

3378 is basically the same as 5278 with an estar base... I have used it in
Bolexes and CP-16s with no problems for years.  The Bolex does have enough
torque to damage things if it jams, but it's not as if jamming is a frequent
problem.  It's higher contrast than the hi-con stock which makes it great
for titling and mattes if you can live with tape splicing it.

For actual sound recording the estar base is a huge win because it does not
expand and contract as much with processing and drying the way acetate does,
so the acetate version only stuck around because it was cheaper.

For a long time I ran Agfa ST-8 through the sound cameras, but that has
become difficult to find.  That's also a polyester base.

I would not worry too much about running the new polyester film stocks in
a well-maintained Bolex.

Re: [Frameworks] optical soundtrack generator?

[Dominic Angerame]

This is a bit off topic for optical soundtracks. 

For decades I have been using a Kodak stock that was produced for making 
optical tracks. Most of my “City Symphony” series was filmed using this stock, 
7378. Kodak discontinued this acetate stock a couple of decades ago. I bought 
as much of this particular material before Kodak stopped making it. They now 
make an estar based stock for making tracks. This estar based is not 
recommended for using in a Bolex since it could jam and damage the camera.

Kodak advised me not to use 7378 for filming. However the cost of .05 per foot 
was tempting. 7378 was tricky to use as a camera stock because of an estimated 
asa of 10-12. The result however is beautiful high contrast image. My films, 
“Continuum”, “Deconstruction Sight”, “Premonition”, “In the Course of Human 
Events”, “The Soul of Things”, “Revelations” were all created using this 
beautiful stock. I continue to film with 7378 with the few remaining rolls that 
I have left. “Revelations” can be seen on Vimeo (just search for Dominic 
Angerame to view this and other films)  My other films are available on a Blu 
Ray collection of my work produced by Re-Voir. Filming with 7378 as a camera 
stock.

Anyone out there that has rolls of 7378 I am interested in purchasing more of 
this material. Please contact me off site at domi...@cinemod.net

 I work a lot with optical sound in my music and performance…. There is
software from a researcher called AEO-Light that you can get as well...

Thank you all for the suggestions of generating an optical track from an audio 
source. I like the idea of finding an optical sound camera (I do have a 16mm 
Auricon that would do this for 16mm, not 35). And the digital angle from 
sixteenmillimeter.com or Scott D’s suggestion sound interesting if a bit 
daunting (I’ve no experience with Processing). Anyway I’ll keep the list posted 
of any progress.

Re: [Frameworks] optical soundtrack generator?

[sstark]

Hi Scott Dorsey, I am interested in your idea of a script for extracting 
information from a .WAV file and creating a modulated white line. I have no 
idea how to do either, though I do have some experience with scripting. What 
scripting tool could do this? How does a script read values in a WAV file?

 

Yes I’m aware of the frame line problem, though those of us in the experimental 
film world might find this “interesting.” 

 

Thanks! Scott Stark

Ahh, I get it, you want a digital image of what the soundtrack would like and
you want to plot it out as part of your filmout.

This turns out not to be an easy thing to do because of the frame lines...
it is very very hard to get the bottom of one frame to line up perfectly with
the top of the next one so there is not some discontinuity 24 times a second.
The Arrilaser recorder can do it, but they take a file that consists of 
frames and turn it into a datastream that consists of individual lines, and
plot a line at a time instead of a frame at a time.

But if you want to try it just to see what happens, it should not be all
that hard to write a little script to create two white lines whose width
varies with modulation.  Pull values one at a time out of a .wav file, 
use them to set the width of the line directly.
