Wie SSIM mit Hybrid?
#2
SSIM/PSNR Werte können aktuell zwei Encoder mit ausgeben x264&x265.
x264->Misc->Main->Adjustmnts->Calculate->SSIM/PSNR
x265->Misc->Metrics->SSIM/PSNR
die Werte werden von den Encodern am Ende des Encodings ausgegeben.
Da es nicht per Frame, sondern nur durchschnittliche Werte ausgegeben werden sind es auch nicht viele.
Die Werte landen:
a. im DebugOutput (ab einem gewissen Level)
b. in der Report Datei die für jeden Job erstellt werden kann (Config->Internals->Create report file)
-> Ein separate Datei für SSIM/PSNR-Werte, für die man einen Ausgabeort festlegen müsste, gibt es nicht. Die Reportdatei wird im Ausgabeordner während der Abarbeitung des Jobs erstellt.

Hier mal ein Beispiel der Informationen aus dem Report für ein x265 encoding:

Die Ausgabe für x264 sieht vergleichbar aus.
