What has changed, is there something I am doing wrong, or am I missing something? I am probing AP9 so our department can upgrade to it. We do not want to double our video storage space.
I know I could use the 265 codec to achieve smaller file size, but that might bring further technical difficulties with the SW into which the videos are integrated.

Thanks in advance,

Hi Vít,

We have checked the case and confirm that this issue happens in version 9 due to our change in 1 option to improve the seeking experience for HTML5 output. However, this has accidentally affected the video output.
We will fix this issue with the video output in the next update, so thank you again for your detection.

Have an effective week ahead!
