Issue since latest FiJi update - ImageJ 1.52p

Hi,

first, hi to everyone here, it is my first post on the forum. I am a physicist based in Paris and I use FiJi on a daily basis for all my image processing tasks.

I have an issue with images and stacks when I try to duplicate, reslice,… them. Typically, I get the following message after an attempt to reslice:

(Fiji Is Just) ImageJ 2.0.0-rc-69/1.52p; Java 1.8.0_202 [64-bit]; Mac OS X 10.14.5; 394MB of 7561MB (5%)

and the following when I try to duplicate a stack:

Has anyone any clue about the source of these problems?
Thanks in advance!

Best wishes

A quick update: the issue pops up when the stack is imported from an avi file using FFMPEG. The same stack imported with the import AVI function does not experience the same issues.

Please post an AVI file and macro that we can use to reproduce this problem. I do not get an error when I import AVI files using File>Import>Movie (FFMPEG) and reslice or duplicate them.
