Hello and thanks for LR Timelapse, I've been enjoying it for many years!

This is the first time I've noticed these terrible looking artifacts appearing in my final renders.

The strange thing is that when I import my sequence into Adobe Premiere (as an image sequence) and then render at the highest quality, I don't get any artifacts. So this makes me believe there is something wrong with the LR timelapse render.

Any suggestions? Look at the attachments for reference.

Thanks,
Jesse

Most likely you are rendering outside the MP4 specifications. Normally LRTimelapse Render Dialog shows a warning then.
There is also a faq covering this: https://forum.lrtimelapse.com/Thread-wei...5#pid39015

Thanks for pointing me in the right direction. I forced the crop to 16:9 and the glitches are gone... that'll work.

Hello, I find this thread and would like to have the follow up question on artefacts here.

In the other thread (https://forum.lrtimelapse.com/Thread-wei...5#pid39015), it is mentioned that "If you use ProRes (LRTimelapse Pro required) those limitations will not be present." Just wonder whether there is any turtorial or thread that discuss about the LRTimelapse 5 Pro rendering setting.

The reason is that I recently upgraded to LRTimelapse 5 Pro, but the rendering artefacts didn't go away (even if I forced it to 16:9)
