The movie could not be opened. The file is not a MP4 file.

[Gustavo Deschamps]

I'm always getting this message when the file is finishing saving the remuxing process. I open the mkv file I want to convert, load subtitles, fetch metadata e save. After a minute or so I get the image below. I'm on Version 1.2.7 (1.2.7), OS X 10.11.6 (15G1217)

What was the file size? Does it happens in 1.2.8 too?

[Gustavo Deschamps]

yes, still the same issue on 1.2.8 file was 1.68gb, but they vary is size

thanks
