Video format that will play on MacOS I exported my animation with all standard settings and used the 3rd Selection in the Video Format Options. When the render was complete, I couldn’t open it because it was in .mkv. What specific settings should I use for a Mac?
You should use FFmpeg video and MPEG-4. It will output a .mp4 file, which is the most common video file format and will probably work on any device, including mac.
