Question

After Effects (2018) strange motion blur artifacts

Hello, I have one big problem while working in AE (CC 2018).

Problem is that while motion blur is turned on for Videocopilot's Element 3d and it's working great, motion blur for other assets like .png images is corrupted.

Issue I am getting is that while PNG file has turned on MB, i get strange lines across images, even though image is not moving itself (it finished animation and is staying still). This happens in CC2018 only, earlier versions havent had this issue. I tried to render video and problem still persist.

All images are in their separated comp.

I guess I will be back to CC2017 for time being. Please provide me with AE CC 14.1 install since 14.2. is not stable on my system. Thank you!

Motion blur ON

Motion blur OFF

Thanks in advance.

Hi All,

Throwing in my experience of the problem - mine's gone totally wild...

As you guys have mentioned I'm guessing it's a PNG issue as the base for my world map in this pic is an enormous PNG file..

Anyway... this is what I get in CC 2017:

And the same frame in CC 2018 when GPU Acceleration is on:

I've reinstalled my copy of CC2017 to work on with for now but that's pretty dramatic. For reference I'm running Windows 10 Pro 64-bit and on an Nvidia GTX 970. Not sure which driver version but will update and see if that helps...

EDIT

Updated to latest graphics drivers (388.13) and no change in the problem. Definitely an issue with PNG's though as swapping the map asset for a PSD version makes the problem go away.... I'm going to keep this project in 2017 for now but will keep an eye on update notes for a change. When i get a little more time I'll see if it's reproduce-able with a new project and send a Bug report.

I am not sure if this will work for you but Ctrl + Alt + Shift + K to go to the Project settings then go to the Color Settings tab and set your Working Space to "sRGB IEC61966-2.1" then hit Ok. Hopefully it will fix for you. I had that strange/weird "artifacts" on some of the frames in some of my projects before and changing my Working Space to sRGB IEC61966-2.1 fixes it.

I'm also having this exact same issue on .png files, it's ridiculous. I have to deliver a project by end of the day too... anyone know a workaround or a 'fake' way of adding motion blur? I'm no expert on AE...

try disabling GPU acceleration  by going to the project settings (edit->project settings) and set video rendering and effects to software only.

    I am not completely sure but I think this bug only effects PNG images. Try converting them to TIFF or PSD files and see what happens.

    I think motion blur is now gpu accelerated which has probably involved a large rewrite of code. Expect many bugs. This is standard practice now with Adobe - release updates before they are fully tested.
