Film door opened effect? at DVinfo.net

Paul Calf · August 30th, 2004, 06:54 AM

Hi im looking to recreate an effect I've seen which i think is caused by the opening on the film door on a film camera. It causes the picture to go white/red/orange very briefly in an overexposed type way.

At the moment i just overlay 4 frames of white color going from semi-transparent to solid to semi-transparent, it kinda gives what im looking for.

Anyone know a better way of creating it or even if this type of effect has a name!?

in post is the best way I can think of... some sort of dissolve transition that comes up over a group of frames so it's not an instant 'cut'.

Plus in post you could ramp up the light so it looks brighter or more 'overexposed'

From what I've heard (and I could have heard wrong) , the cameraman uses a "penlight" to briefly flash the frame in the gate as it moves.

In AfterEffects you would have a white object placed over a few frames quickly ramping up its opacity from 0 to 100%. It may require combining a glow of some sort.

You can do the same thing in Vegas working with opacity.

I've done this but it requires a compositing package.
Simply dissolving a white frame into the footage doesn't quite do it for me.
I use Combustion in this example.

Import your clip into a new workspace.
In Operators/Color Correction add the Discreet Color Corrector.
Go to the frame in your clip that you want to be white.
Highlight the Discreet CC in your workspace and click on "Timeline" in the Control window.
Select all ranges and click "Add Key"
Go to the CC controls and set the Basic "Master" and HighLights" values as following:
"RGB Gain" to 1000 and "Offset" to 255
Click the Animate button to activate keyframe animation.
Go to the first frame you want the effect to begin on and set all the values to the default settings (RGB Gain to 100 and Offset to 0)
Go halfway between the 2 keyframes and set the RGB Gain Offset on the master to 0.
Now go to the last frame of the desired effect and repeat the last two steps.

Now you have an effect that feels more like a burning effect.
The way it usually behaves is that it takes only a couple of frames to get to the white flash frame and 4 to 5 frames to return to normal, but the timing can be customised by sliding the keyframes.

If you have a hard time understanding this or you need a workspace with a preset to see what's happening feel free to PM me.
