Random file Size!?

[Lunde79]

Hi.

Can anyone please tell me the logic behind the filesize the program decides to output.

Settings:

H264
1920x1080
CRF: 23
AAC: 5.1, 44100, 256

Jurassic World 1080p qsv runtime: 2:04:21 filesize: 10.7gb
Avatar 1080p qsv runtime: 2:41:41 filesize: 10.07gb
Marvel's Avengers 1080p - Age Of Ultron 1080p qsv runtime: 2:21:18 filesize: 4.07gb (Uhm, WHAT!?) Ok, it is not True FHD, but anyway.
Cuckoo Clock Heart 1080p qsv runtime: 1:32:34 filesize: 2.57gb (4 audiotracks)

I am a bit confused here. What is the keyfactor for the filesize, since it is so different?

Possibly the encoding method/settings of the source files. If MediaInfo will read them, please analyze the two files with glaring differences and post the results here. The primary determinants are frame size and video bitrate, but other things have an impact.

please update your dvdfab version to 9.2.1.5 or 9.2.1.7 beta
it looks like you are using an older version.
