Hi Christopher, and welcome to SS!
I'm not a big Action writer, so...
I have seen sounds capped and even that can be overdone imho. Here's a couple of links. https://gointothestory.blcklst.....scripts-c4e589c5fbebhttps://www.simplyscripts.net/cgi-bin/Blah/Blah.pl?m-1407932475/s-14/highlight-+Action+scenes/#num14
That second link is more to do with SLUGS in action but might be helpful too.
Having said that I'll let one of the more seasoned Action writers respond in more detail.
There's a Writer's Tournament going on here at SS which might explain why you're not being inundated with answers at the moment.
A few links for you FYI the site:https://www.simplyscripts.net/cgi-bin/Blah/Blah.pl?b-cc/m-1124159895/s-0/https://www.simplyscripts.net/cgi-bin/Blah/Blah.pl?b-knowyou/
And, a scene from BOURNE IDENTITY:
EXT. BELLEVILLE -- STREET -- DAY
And BOURNE and MARIE are running. And he is reaching into
his pocket -- fishing around -- and just as he pulls out the
car keys -- we recognize this as the street they parked
their car on and --
BY MARIE's CAR
BOURNE unlocks the door -- pops MARIE's open. And --
THERE'S A COP -- yelling at them and -- BOURNE hits the
gas -- they fly out of their parking space -- BAM!! The COP
fires, shattering their windshield and there -- up ahead --
THE PROFESSOR coming out -- about to FIRE -- BOURNE aims for
him -- forces him to dive out of the way and --
ONE QUICK MOVE around a TRUCK and they are free.
INT. THE LITTLE RED CAR
BOURNE and MARIE looking back nervously -- so far all over --
ON THE STREET
The PROFESSOR looking around. PEOPLE staring at him --
covered in blood -- the COP racing up -- yelling -- not
yelling for long because the PROFESSOR is firing at him and --
Now the PROFESSOR is moving -- not running -- just a swift
walk and now he's past the truck -- and --
A MOTORCYCLIST comes flying down the street -- oblivious --
going way too fast for these streets and -- the PROFESSOR
swings his gun stock like a bat -- takes him out -- clean
and smooth -- bike crashing to the ground and --
The PROFESSOR grabs the bike and takes off -- SHOOTING at
TWO POLICE CARS just racing to the scene and we are into --
EXT. BELLEVILLE BLVD -- DAY
HIGH SPEED CAR CHASE. And BOURNE better do some fancy
driving because here comes the PROFESSOR -- and he's a lot
faster -- much better armed.
INT. MARIE'S CAR
BOURNE driving. MARIE looking back -- seeing the PROFESSOR
gain on them --
And -- THE PROFESSOR FIRES -- SHREDS the back off their car --
Give me the gun --
And now she's got his shotgun, leaning out the window.
Wait 'till he's close.
BOURNE swerves, up on the sidewalk back onto the street --
slaloms through the traffic -- racing towards an intersection
IN THE INTERSECTION
CARS coming the other way, BOURNE just makes it through --
the PROFESSOR tries to squeeze through -- skidding and --
CRACK! The PROFESSOR hits the front of a car sideways on
his bike -- he is THROWN clear through the intersection,
right into the windshield of an oncoming car and --
He gets up, grabs his gun and works his way towards his bike
and now we see --
EXT. VARIOUS SHOTS AROUND PARIS -- DAY
COPS are mobilizing -- swarming into this area and --
BACK TO THE CAR CHASE --
BOURNE and MARIE pick up a few cops on their tail -- shed
all of them -- the last car goes into an EXPLOSIVE FLIP --
the PROFESSOR is now right behind them. And now we are into --
CRAZY CAR CHASE WITH COPS RIGHT ON THEIR TAIL
BOURNE, MARIE and the PROFESSOR leave a trail of totaled
cars that the cops have to try and navigate through --
finally saying fuck it and hitting a few cars themselves and
now we are into --
CAR CHASE THROUGH NARROW STREETS
MARIE'S CAR and the MOTORCYCLE can pass where the police
cars cannot. BOURNE may be able to shed the cops, but not
the PROFESSOR. And now one quick move and they are --
EXT. QUAI -- DAY
Racing against traffic up the Seine. Past the Louvre. COPS
pursuing on the other side of the river. BOURNE and the
PROFESSOR leaving behind a trail of carnage. And now --
The PROFESSOR is pulling up along side them -- one lane over.
Both swerving to avoid oncoming cars and --
MARIE FIRES -- TWICE -- TAKES out a few windshields. The
PROFESSOR fires at the same time -- MARIE'S CAR DOOR --
GONE -- she's totally exposed but --
THE PROFESSOR -- his BIKE is SPOUTING GAS -- one of the
pellets nailed his tank.
BOURNE AND MARIE --
THE PROFESSOR -- No problem -- he's unwrapping a piece of
duct tape from the barrel of his gun -- two seconds and the
hole is patched and -- BOURNE AND MARIE -- the side of the
car is completely gone -- the PROFESSOR is gaining -- across
the river dozens of police cars are racing alongside. Many
more can be seen on their side -- a road block ahead --
running out of options and --
BOURNE turns hard -- crashes over the sidewalk and flies
down a side street. A POLICE CAR pulls out behind them --
the PROFESSOR can't stop -- skidding hard, turning the bike
sideways, skidding out -- sliding across the ground and
BAMMM!!! SMASHING into a GLASS PHONE BOOTH which shatters.
And he's up -- lifting up his bike and --
BOURNE AND MARIE
SIX POLICE CARS on their tail -- more joining. Every street
they look down has POLICE CARS racing in parallel. Running
out of options and in the background --
THE PROFESSOR is back in the game -- passing the police cars
and up ahead --
THE ROAD IS BLOCKED. POLICE ROAD BLOCK -- cops with guns.
Gotta act quick and -- BOURNE turns hard left -- there's a
metro staircase -- only way out and --
THEY BOUNCE down the stairs. CRASH through the doors down
THE FIRST POLICE CAR -- no way he's following. SLAMMING on
his brakes. SKIDDING to a halt -- SKIDDING sideways --
gonna stop in time -- just at the edge of the steps and then --
THE SECOND POLICE CAR isn't braking -- T-BONES the first
car -- BAM!!! -- sends it rolling sideways down the steps
until it crashes to a halt at the bottom -- upside down.
Download Collateral pdf script too. A personal fav of mine.
Interesting examples of CAPS used in that.
I gather you're writing a Spec so my advice would be to use minimally, and only highlight crucial stuff at risk of it being annoying to the read.
