Page 7 of 8: x264 Options: Partitions

Partitions:

Description: These options determine the partition search types. Generally, you want to enable all of these options whenever possible, as they will improve encoding quality. The "P4x4" option requires the "P8x8" option.
Command Line: --analyse x
(where 'x' is 'p8x8', 'p4x4' {requires 'p8x8'}, 'b8x8', 'i8x8', 'i4x4' , 'none' or 'all')

8x8 DCT:

Description: This option has been separated from the above because it has a different command line flag. This option is required if you want to select the "I8x8" option above.
Command Line: --8x8dct
(enables 8x8 DCT)

This guide is really old especially given the rapid development of x264 (eg. Psy-RDO/Psy-trellis). More comprehensive up-to-date guides can be found at http://mewiki.project357.com/wiki/X264_Settings http://avidemux.org/admWiki/index.php?title=H264

I am using the open-source HandBrake to encode to H.264. One option I'm interested in is "Verbose Logging." But I've tried every command under the sun to get Verbose Logging and have been unsuccessful. I've tried "verbose=1," "v=1" "vb=1" and a bunch of others, but to no avail. Is there a command I'm missing to get Verbose Logging? Any help is appreciated. Also, the documentation on Trellis is scarce. I understand it decides the best way to dole out bitrate and can make the picture sharper. My question is, how (technically) does Trellis accomplish this? Thanx in advance for your help, mikedonahue@mac.com .
