How do I turn off "Two Pass" to one with HandbrakeCLI?

[imkow]

Please detail your question or problem in as much detail as possible:
I've been using HandbrakeCli for several years. I always use the nightly build.
In recent month or so, I found encoding took longer time..then i discovered the HandbrakeCli turns ON the two passes by default.
thus doubled my encoding time...I want to turn it off and have one pass only, but i checked the help text on HandbrakeCli options and found no such an option..I need one pass..

Tell us about your environment. What version of HandBrake? What operating system are you running. etc.
Im using "HandBrakeCLI-20160620144024-31be008-master-win-x86_64.zip"
under an up-to-date Windows 10 64bit
If there was any exception or error displayed, please copy it and paste it here:

a part of output showing
"Video": {
"Bitrate": 1382,

"QSV": {

"Decode": true
},
"Turbo": true,
"TwoPass": true <--------!!!!!!!!! no, it's automatically two passes
}

this is my encoding command:

Code: Select all

HandBrakeCLI.exe -i "K:\_input\1080.mp4" -o "K:\_output\_transcoding\1080_video.m4v" --use-opencl --encoder qsv_h264 --encopts="target-usage=1:extbrc=1:trellis=3:lookahead-depth=60:keyint=120" --vb 1382 --width 1280 --height 720 --custom-anamorphic --display-width 1280 --audio none --verbose 3

i did not specify Two Passes...

Not 100% sure on this but it appears to be defaulting to preset: Fast 1080p30.

This preset uses cq mode but for some reason has 2 pass and turbo enabled, by setting the bitrate you are overriding the cq and thus activating the 2 pass.

That's my guess anyway.

Thank you for pointing out to the presets. I didn't notice the presets...When I looked into those presets i found out the settings in preset is far more detailed than command line switches.
Maybe sometime in recent months, the preset system has been redesigned to replace the "Legacy" presets ..So in nightly builds, every new preset is, by a minor mistake, enabled Two Pass and Turbo Two Passes with TRUE, including those "Very Fast" presets...The trouble is HandbrakeCLI provides no "force one pass" switch to turn off the two pass settings.
i currently get a workaround.. by export and import the preset,
first to see all presets

Code: Select all

handbrakecli --preset-list

find a desired preset and export it to a file

Code: Select all

handbrakecli --preset-export "HQ 1080p30 Surround" --preset-export-file "HQ1080p30Surround.txt"

edit the HQ1080p30Surround.txt, turn off two pass switches.

Code: Select all

           
           "VideoTurboTwoPass": true, -->false,
            "VideoTwoPass": true, -->false,

import the file in command line when encoding

Code: Select all

HandBrakeCLI.exe -i "K:\_input\1080.mp4" -o "K:\_output\_transcoding\1080_video.m4v" --use-opencl --encoder qsv_h264 --encopts="target-usage=1:extbrc=1:trellis=3:lookahead-depth=60:keyint=120" --vb 1382 --width 1280 --height 720 --custom-anamorphic --display-width 1280 --audio none --verbose 3  --preset-import-file "MyOnePassHQ1080p30Surround.txt"     <<<----!! import the corrected preset

then it become one pass happily!...
though this could be easier if there were a command line switch(e.g. --one-pass)to force one pass or turn off two pass..
it's just a tiny bug of imperfection in the nightly build...no biggie :_)

[BradleyS]

@imkow Thanks for bringing this to our attention. The new presets do indeed use constant quality by default, but also have similar 2-pass abr settings available just a click away. We need to add --no-two-pass and --no-turbo (or similar) to make it easy to override this on the CLI.

Also, if/when this lands the default preset on the CLI will be mostly automatic settings, so there is less to override in general (you can still import and use presets from file/GUI).

[BradleyS]

I created a new issue on GitHub in case you would like to watch for any code updates: https://github.com/HandBrake/HandBrake/issues/234

In the meantime, your solution of using a custom preset is the correct workaround. Thanks!
