Could you please check log files in VTM folder? They are located in "Logs" folder.

Ok, I am going to add WebP animation to the next release of the program.

WebP is not supported by Firefox by default. WebM is supported by all popular browsers by default. Also I guess what WebM has much smaller filesize.
Need to learn more about WebP.
Thank you for your post.

Need to investigate that opportunity.

Currently that is not possible.
Videos are added one by one.
Only picture folders are added as a folder.

1) Just press Export and you will get VTM Options file to share.
2) Try to set "Try substituting for any color frames" checkbox OFF in Environment window.
3) What is written in log file (press on a log button in top right corner of the main window).
4) Do all files have the same issue?

Please post your Options please.

That is not a bug.
Just not enough video length to fit your matrix (and Options).
Supposedly, you have set time step in Options.

Update check is present in all my programs.
It is not obvious, but described in FAQ (with a screenshot):

Hi.
Thank you for your feedback.
That is a bug. I will fix it.

I would like to spread the word about new animation features, but do not know how
