Hello, I have a problem with the Time Displacement effect, but I feel like I’m missing something. Applying this effect significantly increases my render time—normally, my renders take about 40 minutes, but with this effect, they take many hours longer. But today, the render doesn’t even start and gets stuck at 0%. I had to remove the effect to continue with my project today.
I suspect the effect is too heavy to render because, at full resolution, it won’t even preview and just loads indefinitely. Strangely, at 1/4 resolution, it previews and caches the entire area without issues. I expected it to render slowly, but instead, it doesn’t start at all.
I might not fully understand how this effect works, especially why it causes such a performance hit. I know that whether the CPU or GPU is used depends on the specific effects, but I don’t really understand it that well. Here’s my workflow: I create effects over still PNG images or shapes (no video footage involved), animate a few keyframes of movements and in this case the effects in the image below, I work at 23.976 fps in 4K not more than 18 seconds.
When rendering, I have to use OpenGL because CUDA get stuck and fails in most of my projects. Additionally, I rely on the NVIDIA Game Ready Driver since the Studio Driver for some reason fails every time with Media Encoder on my system .
I have the latest 2025 updates for both After Effects and Media Encoder, but this issue has been occurring since the 2024 versions.
