| Hi!
I´m trying to reencode a BD-movie to make it fit on a DVD-9 (AVCHD format). I´ve been remuxing it with txRemux and is now about to reencode the video with Mencoder. All I want is to get the bitrate down, without any other changes... When the encoding starts, this puzzles me: Movie-Aspect is 1.78:1 - prescaling to correct movie aspect. Now, please remember that I want the video, part from bitrate, as unaltered as possible. Besides, prescaling would push the encodingtimes in the wrong direction... Why is Mencoder applying this prescaling? The input-file should be 1920x1080 and that is what I want in the output-file! Is there a way to prevent this prescaling? I´m using the following commands: Mencoder.exe -nosound -noskip -mc 0 -of rawvideo -o "D:\Hitman Demux2\HitmanVideo.h264" -ovc x264 -x264encopts bitrate=9500:threads=auto:frameref=1:bframes=2:deblock:level=41:direct_pred=auto:partitions=p8x8,b8x8:me=hex:me_range=16:subq=1:chroma_me:mixed_refs:bime:trellis=1:weight_b:b_pyramid:nr= 0:pass=1 -vf harddup "D:\Hitman Demux2\00002.track_4113.264" -mc 0 -noskip Mencoder.exe -nosound -noskip -mc 0 -of rawvideo -o "D:\Hitman Demux2\HitmanVideo.h264" -ovc x264 -x264encopts bitrate=9500:threads=auto:frameref=2:bframes=2:deblock:level=41:direct_pred=auto:direct_pred=auto:partitions=p8x8,b8x8:me=hex:me_range=16:subq=5:chroma_me:mixed_refs:bime:trellis=1:weigh t_b:b_pyramid:nr=0:pass=2 -vf harddup "D:\Hitman Demux2\00002.track_4113.264" -mc 0 -noskip When starting the encode I get this: MEncoder Sherpya-SVN-r25803-4.2.2 (C) 2000-2008 MPlayer Team CPU: Intel(R) Pentium(R) 4 CPU 3.60GHz (Family: 15, Model: 4, Stepping CPUflags: Type: 15 MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection. success: format: 0 data: 0x0 - 0xce911fa H264-ES file format detected.

| Jepp, me again...
Just realized that the resulting video after encoding (takes forever, even with a small sampel of the movie...) ends up with a resolution of 1920x1084...! So I tried to apply a crop=1920:1080:0:0, trying to prevent that. However I still end up with 1920x1084... What am I doing wrong? Please help! |
