With new HB 1.3.0 I have anomaly high bitrate when doing BOB deinterlace comparing to regular deinterlace and any deinterlace used in HB 1.2.2
Steps to reproduce the problem:
Load interlaced sample. Here's one 30sec sample 576i: https://megaupload.is/f7xf09B7n6/handbrakebobtest_rar
Shared settings for all tests:
Codec H265 / Framerate SameAsSource Variable / RF20 / medium / tune none / profile&level auto
Extra settings: no-sao:aq-mode=1
I did 2 encodes with HB 1.3.0 with deinterlaces yadif/default/detectionOff and yadif/bob/detectionOff
And 2 encodes with HB 1.2.2 with the same deinterlace pair.
Resulted bitrate:
HB 1.3.0 yadif/default/off: 2341.35 kbps - 25fps
HB 1.3.0 yadif/bob/off: 3847.63 kbps - this is anomaly, should be ~2700. 50fps
HB 1.2.2 yadif/default/off: 2406.34 kbps - 25fps
HB 1.2.2 yadif/bob/off: 2715.37 kbps - 50fps
HandBrake version: 1.3.0
Operating system and version: Windows 10 x64
