I have a simple project with a single a/v track. On the video track, I have applied the (fixed) crop/transform/tilt effect to zoom in to part of the image.
Whenever I play a part of the video, the video and audio stutter for a couple of seconds and then play normally. When rendered. the video is ok.
I have a fairly powerful PC (12-core Intel i7-8700 @ 3.20GHz) with 32G DDR4 memory and NVMe 'disk'). Did I miss something in the settings?

Even I cannnot provide a solution, I would like to say, that it looks very similar to my problem. For me it happens when the project becomes a bit more complex (some effects and especially if I shorten certain takes at the beginning) In very simple projects and if the takes are not too big, it works smoothly. Im interested in the further discussion here, too.
