Hello everybody

I'm trying to create the "star trail" effect in GEM (like this:

), and apply it on some videos.
I tried two methods: with two pix_snap photographing each other, and with motion effects like pix_biquad and pix_tIIR.
With the first method I have CPU load problems, while with the second method I lose the original colors trying to get a permanent trail.
Do you have any advice on how to do it? Thanks

Maybe [pix_delay]?

Hi Johnny,
with some [separator]->[pix_delay] I can create a trail, but I can't find a way to make the trail persistent.
