Ich wollte mich nochmal zurückmelden, mit der Sache mit dem, das x264 kein HDR kann.
Ich hab jetzt eine x265 (HDR) 10-Bit zu x264 10-Bit enkodiert, ohne HDR to SDR oder Tonemapping. Wie geht das? Ich hab jetzt die exakt gleichen VUI wie in x265 in x264, nur das x264 jetzt als SDR erkannt wird.
Ich hatte es am Anfang mit NVENC x264 zum testen gemacht, in nur 8-Bit und da sah es auch genauso aus.
Media Info sagt bei beiden:
HDR format : SMPTE ST 2086, HDR10 compatible
Color range : Limited
Color primaries : BT.2020
Transfer characteristics : PQ
Matrix coefficients : BT.2020 non-constant
Mastering display color pri : BT.2020
Mastering display luminance : min: 0.0001 cd/m2, max: 1000 cd/m2
ich dachte man muss HDR to SDR bzw. Tonemapping machen?
im x264 sieht es jetzt genauso aus wie im x265.
Das ist die MediaInfo vom Original

Also kann x264 doch HDR? Das einzige, was ist jetzt bei x264 nicht mehr habe, sind halt die master display Werte. Hat der das vielleicht von der Blurray auf x265 schon getonemapped? Aber warum sollte man das machen?
Ich frage halt, weil ich verstehen will, warum das so ist.
Grüße
