Weird Artefacting
Hi guys,
I’ve got a shot of a fish underwater, it’s the last shot in a 40 minute comedy drama film and the idea is that a fish in a bag has made it floating all the way from the UK to Austraila.
I’ve put it into After Effects and put in a fake lens flare & some tilt shit effects with an adjustment and fast blur with a mask around the fish. I also used Magic Bullett Starglow.
My question is… when I export it I get lots of weird compression artefacts as seen here: https://tinyurl.com/bohaqw5
Footage recorded on a Canon 550D as a .mov file, used MPEG Streamclip to convert it to ProRes422. Edited in After Effects and Exported as a QT movie in ProRes422.
Here is the video on Vimeo (password is ‘fish’): https://vimeo.com/55168498
Thanks!

Do you have any of these artifacts on your original footage?
What is your project setting? are you working in 8-bit? what is your color space?I would try to work in 16-bit at least.

A few things to try:
32 bit color space
use Neat Video or AE’s own remove grain to smooth out the initial footage
add noise to the final shotTudor “Ted” Jelescu

Thanks guys, I changed my project settings to 32 Bit and it worked brilliantly.
How do/ should I set my default project settings to 32 Bit and what actually is the difference?
Thanks so much for the help.
