Hello. I'm receiving this message (image attached) when attempting to render a video. It's happened for the second time now with this particular sequence. I have it set to original resolution, so with a Nikon D810 it's pretty hi-res at 7360 x 4912. This particular sequence is a little long, at 1458 frames. It does make a .mov file despite the warning message, but QuickTime won't open it, saying the file is not compatible with QT Player. But I can generate full-res .mov files from other sequences with no problem. Also, I can render 4K videos from this sequence with no problems. It's the full resolution videos that won't work. I'm using a 2017 iMac Pro with MacOS Monterey, LightRoom latest version, LRTimeLapse latest version.

Never mind, I think I figured it out. I looks like I have very little disk space left, which is surprising since I recently moved lots of large files from desktop to hard drives. I'll look into this and let y'all know.

Perfect. For more details check the log, it should tell you about shortage of disk space.

Yep, it was very low disk space that created the warning. All is good!
