Light Streaks
Hi,
I recently saw a tutorial about creating light streaks as seen on the ipod nano advert.
I’ve followed the tutorial and created my light streaks although I now wish to have these streaks floating around a different background other than black
for an animation I’m working on. If I try dropping in a different background these streaks disappear. Do you know how I can place this effect on a different background?I would be most grateful for any help/advice.
Thanks in advance,
Matt.

If you are talking about Andrew Kramer’s tutorial “Creating Light Streaks” then the simplist way to do it is to precompose the existing layers, name the new precomp something like “streaks” and drop your new bg under the streaks precomp. Then change the precomp mode to add, and there you have it.

Hi Mark,
Is this done by rendering out the streak layers and then reimporting back into after effects, or is precomposing something different? I have tried this but the streaks don’t appear bright enough, even after adding brightness and contrast filters.
Thanks

No, you dont need to prerender anything. select all of your layers, then go to the top menu and click “Layer” then click precompose at the bottom. This will place all of your layers in a new composition. Then drop your new footage below the precomp and change the precom mode to add. The brights will shine through and the blacks will be transparent.

I should add (pun intended) that if you are using the add blending mode over a very light background you will not see the light streaks very well as they will be clipped at 1.0 or white. Try darkening your background to make the light streaks ‘brighter.’

Do you guys know that Andrew has put up a new tutorial on his site covering exactly this!? Or, is it because of this thread he’s done it…

Which new tutorial? If you are talking about his new “Growing 3D Vines” tutorial (added March 17, 2008), it has nothing to do with the light streaks tutorials. If you are talking about another new tutorial, could you post a link, as it’s not on his tutorials page?

If you go to his site (videocopilot.net) then there’s a tute called ‘Light Streaks 2’ which shows a workaround for the adjustment layer colourizing thing and also animating the stroke with a null instead of a light. He composites it over a street scene.

Yes, I’ve seen the “Light Streaks 2” tutorial. However, your post implied that there was a new tutorial, recently posted. “Light Streaks 2” was posted a year ago.
