Render glitches in Fusion - and constant crashes

PostSat Jun 19, 2021 10:58 am

Hi everybody... I´m sorry if this was covered somewhere else, but my english is not as good as that I would find the right words to describe this glitch apparently...

I am compositing in Fusion with mp4 clips from a SOny A7SIII. And besides crashing every other 10 minutes i get these very strange render glitches:

they apear every other frame, sometimes all frames - and they are moving. im talking about the transparent lines ...

I use a delta key and a 3D camera to place the clips inside a camera movement.

you have any idea? im on the latest 17.2.1 Build 12

thanks so much!!

Describe your hardware in detail and your resolution.

oh yes, sure

- its a macbook pro 16" 2019 with AMD Radeon Pro 5500M 4 GB; 2,3 GHz 8-Core Intel Core i9 & 16 GB 2667 MHz DDR4; running MacOS 10.15.7

and the material is 4K

i know, the machine is way to underpowered - but these renderissues should not happen ... i get the crashes maybe when ram is full - but also this should be handled differently ... or am i wrong?

thanks!!

One thing I would try is Transcoding the H.264 originals into a more robust codec like ProRes and using that for editing.

It is underpowered for 4K. But if you are trying to render into H.264, try ProRes for output instead.
