encoding settings in mediainfo

[ronny85]

well, this is my first approach to hevc

in x264 i can see the crf used during the conversion even in mediainfo gui

how can i know what kind of settings (crf used)have been used in a hevc conversion?

there is no encoding settings


thank you

This totally depends on what meta information the particular encoder software embeds into the stream!

x265 adds an info tag to the HEVC stream which is similar to the info tag that x264 adds to the AVC stream. MediaInfo (current version), for example, can show this information:

Other HEVC encoders may add similar information to the stream - or they add no information at all. Other HEVC encoders may not even support a rate-control mode like "CRF".

thank you, i am using hevc_qsv

and i am not even sure if a -q option is available

[MeteorRain]

It's just an arbitrary text that was written into the stream by x264/x265. If hevc_qsv does not write that, then there will be none to display.
