Source over 25G and I want to compress to 25G. Output size should be about 23.9G, right? But after process done, I get output size about 15G - 20G. This is normal? Underwater BD - Size Before Compress 24.35G - Size After Compress 15.3G Bombshell BD - Size Before Compress 31.71G - Size After Compress 20.62G The Gallows Act II BD - Size Before Compress 31.17G - Size After Compress 15.88G Polaroid BD - Size Before Compress 27.12G - Size After Compress 16.23G
Sometimes the source picture quality or detail is too low to really reach the preset bit rate. Commercial Blu-ray discs usually add filler data to "compensate" for this and get the disc full.
