Hello. I have to transcode around 150 hours of DNxHD 120 footage (25 fps, 1080i) via Adobe Media Encoder to H.264 MP4 files. I use the "HD 1080i 25" preset (Level 4.1, VBR, 1 pass, target bitrate 32 Mbps) and it takes two i7 CPUs (3770k and 4790k in two machines) roughly 1 minute to render 40 to 50 seconds of footage. AME is only using 50 to 60 percent of the CPU. HandBrake would produces similar transcoding durations with lower quality settings. The source clips are QT Reference files (MOV and WAV, MOVs linking to MXF files in Avid MediaFiles folder). Is DNxHD the reason for the "delay"? PS: I use AME CC 2014 on OS X 10.8.5 (3770k) and OS X 10.10.1 (4790k).
