Quality factor field is grayed out in h.265 options

[calande]

Hello,

I'm trying to capture a video with a video capture board. I'd like to save the input in h.265 and AAC format. I'd like to set a quality factor of 26, but the field is grayed out:



I tried adding the following additional option in the lower field: --crf 26 but this code is not taken into account. No matter what value, the bit rate doesn't change to match the quality requested.
Could you help me, please?
Thank you.

Any idea?

True, I can reproduce the issue. TBH I have checked all of the video options and I don't understand why we can't access this setting.
Let's hope a dev will answer that, otherwise you should create a new ticket on the VLC Trac with your above report and the link to this thread:

Thank you! We'll see if a dev see this thread. In the meanwhile, I'm using ffmpeg.
