Hi, with LRT flickering has disappeared but light ondulations appear while running the video on a Mac (with retina windscreen), I heard about a problem of interlacing frames ? Somebody encountered the problem ? Thank you for answer
Sorry, I cannot say anything without seeing what you are talking about. Please upload the video somewhere and share a link.
LRTimelapse does no interlace at all it just assembles images to progressive footage.
I think what you are referring to is banding artifacts. We already covered this a couple of times here in the forum, you might use the search feature for "banding".
Basically, it happens due to the smooth transitions in the sky and the video compression that gets applied. There are a couple of things, you can do to ease that, for example add a bit of noise (grain) to the images, increase the quality setting when rendering, rendering in a better coded (like Prores) etc.
