Please also post the full client log and the content of the export.log
inside your .minecraft folder. (Please put those two inside spoiler tags or some pastebin)
// Edit // Did you test whether rendering works with some smaller sequence beforehand?
I don't have the export.log anymore, but a extremely strange thing happened!
I have wanted to make a shorter replay to test if it even works, but then...
When i have pressed the render button (The rendering setting were the same) the screen was blinking blank, loading screen, blank, loading screen....... (About 10 times) Then finally the video was rendered.
Then... This extremely strange thing happened!

(Also, no. The video didn't export properly not even this time.)
