Using 2.6.18 64-bit 170113.
Qz in the Frame Type section shows (02) for all I, P & B frames.
Opened an 11min 1080p60 50Mbps MP4. 3.47GB
Did a 2-pass MP4 x264 re-encode to 800MB. Original frame-size and frame-rate. Quantitiser shown on the Advanced screen as 31-32 during the 2nd pass.
Also another 2-pass to 300MB. Quantitiser: 36-37.
Re-encoded filesizes as expected, but Qz always show (02) as I frame-advance (R.arrow) through the original file and the 2 re-encodes.
Should the Qz display be showing values between 10-51, as suggested by "qpmin=10 qpmax=51 qpstep=4" in the stats file?
