Video Export is not rendering animations properly

Hello guys,

currently I am working on my final bachelor project, so far everything good with Unreal Engine.

But now at my last task - rendering the video of the project - I bumped into a problem (bug?).

If I play the video in the Editor, it works without problems. But when I want to export it, it does not render the keyframes on the spotlights properly.

Here is a demonstration (warning epilepsy)
Working (editor): - YouTube
Not working (export): - YouTube

Hope somebody can help me, I tried to fix this problem now for hours and don’t know what to do.

Unfortunately not. But I did a workaround.
I opened up my screen recorder (WIN+G) and then played in Unreal Engine the Project in Full Screen, while I was recording.
There was a little bit of a delay on some special effects (Light beam), but everything else was in realtime.

It’s a shame that this bug exists tbh, but yeah. Better to find a workaround then to throw all the invested hours away.

how did you resolve this? i have the same problem
