HandBrake error during conversion

[Filippo]

Hello,
I'm converting a list of files to .mkv with HandBrake, they should be all equals but some file returns error and stops encoding, jumping to the next.
I've inspected the log and I see a long list of "avformatMux: track 2, av_interleaved_write_frame failed with error 'Permission denied'" and "Last error repeated 3 times".

How can I solve this error?

Thank you

Usually permission denied means it doesn't have access to the output folder (Windows file/folder permissions)

It's weird because only few files got that problem, and they're all saved to the same folder.

Compare a log where it worked Vs. where it failed and perhaps you'll see something.
Also check the file names, sometimes embedded spaces or special chracters can cause issues
