Mezzmo is remuxing that file, not really transcoding, so the video stream is untouched. It's possible that HB 0.9.5 encoding is broken. To dig deeper into this, it would be great if we could have one of the original files here - then I could test it with current FFmpeg and also the previous one and also an up-to-date build and see if it's our FFmpeg or the one used by HB.
