Smaller file but higher bitrate?

Post by rugbyguy9 » Fri Jan 19, 2018 5:19 am

Hi,

I was going through my movies and noticed that some smaller GB movies had a higher bitrate than larger GB movies how is that possible?

For the below examples I remuxed the movies from originals and I've removed all audio except for truehd and the 5.1 dolby soundtracks. Also subtitles were also removed except for English.

John Wick
1:41:11
HVEC h265 Main 10@L5.1
TrueHD 7.1, AC3 5.1
44.9 GB
63645 kbps

Starship Trooper
2:09:28
HVEC h265 Main 10@L5.1
TrueHD 7.1, AC3 5.1
51.1 GB
56587 kbps

One movie is half an hour longer than the other, and that's why it has a larger file size even though it has a lower bitrate.

The shorter movie, because it's not as long they could push the bitrate to get higher video quality but still within a certain amount of GB.

The longer movie, they didn't use as high a bitrate presumably to get the length of the movie to fit within a certain amount of GB.
