Hello @rigaya,

when checking the features of the arc a770,

This is the result for h265:

Which means that --la-quality slow should not work or at least provide an message that it was disabled? However it doesn't show a warning nor error or something else. Is that indented behaviour? Or did I misunderstand something?

--la-quality only takes effect when used with --la, --la-hrd, --la-icq. Therefore, no message will be shown when used with other rate control mode options.

OK. Does that mean when I use --cqp I can not determine the --la-depth ?

quamt avatar Jun 28 '23 09:06 quamt

Yes, with cqp, la-depth will not take effect(will be ignored).

I see. Is there anywhere a table or similar where it can be checked which option does work with which other option? Something like a Wiki would be nice, which might avoid repeating questions.

Unfortunately not. As QSVEnc has many options, we can think of various combinations of options, which I won’t be able to cover orlando continuously maintain a table in a limited amount of time.

Ok, understand. Does that mean it will also not show when debug is enabled?

Closing as completed.
