Squeeze’s only choice is mainconcept H264. I did read on another forum that there is a bug in encore where it doesn’t like 2-pass vbr and/or high profile. However, I just tried using the preset with 1-pass vbr main profile, 1-pass vbr high profile, 2-pass vbr main profile, and still no luck. Here are the preset settings if that helps to shed light on anything:
Mainconcept H.264
2pass vbr
1080i 29.97
25,000 Kbps
constrain at 30,000 Kbps
level 4.1
high AVC profile
interlaced
top field first
CABAC encoding entropy mode
key frames every 300 frames
auto key frame on scene change (50)
use b-pictures 3
use b-slices as reference (unchecked)
multiple slices (0)
reference frames (2)
