Yes there is a script! I haven’t seen it for ten years, but its out there. Sorry to be of no help now, but maybe I can find it.

Indeed, I always do a double render.

The first stage an image sequence render. Image sequences can proceed the render at the point of failure (multi machine settings turned “on” )and secondary rendermachines can drop in for support. Set the rendering to replace the original sequence by a proxy and add to the second rendering without the “ignore proxy” settings. It isolates any problem of different codecs and speeds up rendering if more than one output format is needed

…However your problem also sounds like a multiprocessing issue. I could always only allocate max 3GB to one core. So make sure its off if available. If that doesnt work you still can force AE to purge its memory.

You also coulde have used the “transform” effect. It lets you animate the position relative to the layer position and duplicated the effects to a second dot. Than linking the second effect to the first effect and use copy’s from the second to all other dots, making the first one the “master” dot.

So i had to do a work around to counterzoom the shot, not having the original footage (thats the precomp)

Do a freeze frame on the first frame, which isn’t a clean plate. So i had to use the second frame, to show it can be done, tiled it and blurred it (Thats the lower layer)

Than reshape a regular mask with the pentool

Xvid often uses GOP settings. It might be possible you’ve chosen a number that canot be divided by your settings?

I will see if i get some spare time to help out. I sugest to reshape the mask by using the pen tool and keep what you like (hole and flaps) and use a freez frame at the lower layer without the folds. Its a dynamic proces, you’r inventing while building it.

Try turning off the drop shadow and see what happens. Because I don’t see transparent pixels but a small gradient.

A general reason to add lens flares, is to add imperfection to virtual footage. However if the flare looks fake, you can’t sell the footage as being real. Many flares look to synthetic.

So building flares from scratch, by simulating physics might do the job. But reinventing the wheel wasn’t my target. But it seems to be a bit harder than i thought.

Thanks for the input guys

Hi,

Its the *.pdf added to that article

https://resources.mpi-inf.mpg.de/lensflareRendering/pdf/flare.pdf

“At the other end of the scale, sophisticated techniques have been
demonstrated that involve ray or path tracing through a virtual lens
with all of its optical elements. The results are near-accurate but
very costly to compute, with typical rendering times in the order of
several hours per frame on a current desktop computer.”

I already tried just building one lens in AE, which seems to work. But I gues I aint the first one?

Hi Dave,

Ah yes Adobe didn’t use the options. But also no third party’s or private developments? Because I found this article from 2011 that already referred to generating this type of flares.
