Hi together,
I have a problem with encoding a 550 seconds long video file (output format is Quicktime) coming from Premiere Pro CS6. The video is 1080p/25fps and it was recorded in a car while driving, so its very motion biased. (I got an Intel i7-2630QM with 8GM RAM and nVidia GT550M inside my laptop.)
Now, when I convert the video to H.264 Blu-ray (custom settings: VBR 2 passes, Average bitrate 10MBit/s, Max.: 12 MBit/s) I always notice that the filesize is way too big. In fact, its always 4.97GB.
I encoded the video several times again with decreased average and max. bitrate (I decreased it several times by 2 MBit/s both avg. and max.) and the funny thing is, the filesize remains the same! No matter whether I select 12Mbit/s, 10 or 8. Its still around 5GB.
12MBit/s * 550 seconds = 1.5MB/s * 550 seconds = 825MB That should be the filesize by assuming the maximum(!) Bitrate of 12Mbit/s. But why the heck do I get a 5GB file?
So the problem is that the filesize absolutely doesn't correspond with the Mbit/s settings. Anybody experienced same issue already?
Thanks in advance! =)
