Looks like the split output is no longer adding XofY to the end of the filenames.

Hello EpicDim,

We have tested and confirmed that the split file names are correct.
If the input file is ABC.mp4 and split into 2 files, the output files are "ABC - 1of2.mp4" and "ABC - 2of2.mp4".
Could you be more specific if you still have the issue?

Thank you.

I put in OutputFilename in the field and the list of files I get are now:
OutputFilename.mp4
OutputFilename (2).mp4
OutputFilename (3).mp4
OutputFilename (4).mp4
...

I used to get as you state above:
OutputFilename - 1ofX.mp4
...

Hello EpicDim,

Thank you for getting back to us.
Could you please attach a log file?

Bandicut menu -> Configuration (F5) -> Check 'Create a log file (.log)'.

A log file (.log) will be created to the output folder when you start editing.

Thank you.

I don't know what happened, but it's back to normal again. Very weird.
