I’ve worked with PfTrak 4.0 from Pixel Farm Company on two different projects which required some heavy 3d tracking and I can say I’ve been very pleased with the results.
I’ve worked with SynthEyes previously but PfTrack gave better results and in no time.
You can try SynthEyes because it’s a free program and it even has some video tutorials on the site to get you started. This is the site : https://www.ssontech.com/index.html , if you want to check it;)
I’ve worked with PfTrack from PixelFarm (https://www.thepixelfarm.co.uk/products/products.aspx?PID=3) and I’m very satisfied by it. It’s kinna expensive. If u want a simpler solution try SynthEyes (https://www.ssontech.com/index.html).
U should check the video tutorials and the manual to get a better understanding of how this tracking programs work.
They export the tracked data in a Maya format (.ma) which can be imported in After Effects.
that’s very clearly doable using Andrew Kramer’s Light Streaks tutorial ( https://www.creativecow.net/articles/kramer_andrew/nano/index.html ). You may want to play with the aux system in particular to get that dripping ink effect, and also with the particles/second to make it look more natural. Maybe I’ll try it when I have some time and post an aep if I get it right.
