  • AE 2018.1 – ReFlex Morph crashes

    Posted by Richard Smith on April 8, 2018 at 12:52 pm

    I’ve been using morph for a few months without any problems. Since the latest 2018 updates to After Effects, I’m finding my renders crash after a few hours. Error about the output is invalid.

    Are there any known issues?

    I use 5.2.7.

    I also find I still get green screen effect with GPU rendering. I’m using a 2GB GTX 760. I think I’m running out of video memory but I thought the supported memory is 1GB + My renders presently take 17 hours + to complete, so eager to get GPU working. What videos cards do others use? 4GB? 1050?

    Not aware of memory leaks on our side, is this RE:Flex Morph or Motion Morph?
    I hope you had auto-save on!

    There has been some reports on an AE list about using overlays in AE latest causing erratic performance in latest (without our tools), this might or not be related.

    If it crashes after a few hours, it could be a tiny memory leak that accumulates but also coincidental (for example if you at some point start playing movies in Firefox it might cache memory which suddenly is not available…). Perhaps after an hour of use you can check memory usage and compare to what your preference says about how much to leave for other apps.

    We are at NAB this week, but will follow up next monday if you write to techsupport@

    With regards to GPU, it actually depends on resolution and bit depth of project AND if you have other AE effect that use the GPU before RE:Flex. And it also depends if you use Render Queue or AME. If you start AME it will launch a completely different instance and now the GPU and RAM has to be shared.

    Thanks for the reply. I have not applied any effects at all, as I apply colour correction etc in the final rendered sequence. Plus I’m morphing 100’s of photos so could well be memory leak. I can typically use 50GB of ram for a render, plus my images are 4K.

    I worked away around it for now, and instead of rendering in AVI format, I use multi-machine render, split into photoshop sequence of 1000’s of files, then imported those as a sequence to render back to AVI. AVI is dropped into premiere for usual editing.

    Should I be looking at a more powerful graphics card? 4GB or 6GB GTX to handle the morphing in 4K?

    What can typically take 17-24 hours in CPU, takes an hour in GPU (except all the Reflex morphed parts are green)

    I was looking at maybe a 1050 GTX? I’m using reference MSI 760 GTX 2GB at moment.
