Flash effect with Adobe Premiere

You will learn how to create a very popular flash transition effect and how to trigger effects at specific time.

I presume you have your video cut and ready to apply the effect.

Go to Video Effects, click Adjust then click and hold Levels ...

... and drag it to the clip you want to apply the flash/strobe effect to.

Move the time line to exact point of the clip where you want to add the transition effect.

I'm going to move it to just a few moments (4 milliseconds) before one clip ends and another begins (see picture).

Now click the Effect Controls tab, and open Levels (see picture).

Click the Toggle animation button next to (RGB) White Input Level (see picture).

A little time point appeared on the right side, representing the trigger when the effect gets activated.

Now set the time for about 4 milliseconds forwards (see picture).

You can click the time and just enter the milliseconds.

In my case it was 00:00:04:12 and I added 4 so I've set it to 00:00:04:16.

Open (RGB) White Input and set it to 0 (see picture).

You must click the little white down arrow next to a little stop watch to display the settings.

And another little trigger appeared representing another change in time for this effect.

In my case the effect will start at 00:00:04:12 then the value of (RGB) White Input will drop from 255 to 0 in a matter of 4 milliseconds creating a flash effect.

This is a screen shot of my clip, at about 1 millisecond after the Levels effects was triggered.
