This gives us a good looking re-encoding that +# does a good job preserving the quality of the source video (at least for +# twitch streams I'm trimming) but the bitrate might be higher or lower than +# the source. The quality metric will fluctuate during encoding because NVENC +# does't use a fixed quantization parameter. -cq:v is a target, not a constraint. +# So you can have quite the fluctuating (or high) bitrate with these two params. +# In order to set a birate cap that is prioritized over visual fidelity, we can +# add in: +# -maxrate:v -bufsize:v +# (with bufsize typically being double the maxrate) +# +# Using this with the vbr and crf params tells the NVENC encoder to try to +# encode at a perceptual quality level around CQ=20 but keep the bitrate under +# 6000 kbps (constrained VBR). If a scene is too complex to maintain CQ=20 +# within the bitrate cap, the encoder will: +# * Raise the quantizer (lower quality) to obey the -maxrate +# * Result: CQ metric fluctuates upward +# If a scene is simple: +# * Encoder can exceed CQ=20 (e.g. better quality) while staying under maxrate +# * Result: CQ metric fluctuates downward +# +# To have a mostly fixed bitrate with no variable quality, use trim-video-target-rate + +time ffmpeg -y -stats -loglevel level+error -hwaccel cuda -hwaccel_output_format cuda $timing_args -accurate_seek -i "$filename.$extension" -c:v h264_nvenc -profile:v high -preset 3 -rc:v vbr -cq:v $target_crf -maxrate:v $max_bitrate -bufsize:v $bufsize -c:a copy -movflags +faststart "$output" + +printf "\n${GREEN}${BOLD}Finished trimming${NORMAL}\n\n" + diff --git a/dotfiles/windows/custom_hosts_list.txt b/dotfiles/windows/custom_hosts_list.txt index ae607c9..e96d2f6 100644 --- a/dotfiles/windows/custom_hosts_list.txt +++ b/dotfiles/windows/custom_hosts_list.txt @@ -59,18 +59,18 @@ 127.0.0.1 www.wip2.adobe.com www.wip3.adobe.com www.wip4.adobe.com wwis-dubc1-vip60.adobe.com crl.verisign.net CRL.VERISIGN.NET ood.opsource.net # Block Facebook -127.0.0.1 www.facebook.com -127.0.0.1 facebook.com -127.0.0.1 static.ak.fbcdn.net -127.0.0.1 www.static.ak.fbcdn.net -127.0.0.1 login.facebook.com -127.0.0.1 www.login.facebook.com -127.0.0.1 fbcdn.net -127.0.0.1 www.fbcdn.net -127.0.0.1 fbcdn.com -127.0.0.1 www.fbcdn.com -127.0.0.1 static.ak.connect.facebook.com -127.0.0.1 www.static.ak.connect.facebook.com +#127.0.0.1 www.facebook.com +#127.0.0.1 facebook.com +#127.0.0.1 static.ak.fbcdn.net +#127.0.0.1 www.static.ak.fbcdn.net +#127.0.0.1 login.facebook.com +#127.0.0.1 www.login.facebook.com +#127.0.0.1 fbcdn.net +#127.0.0.1 www.fbcdn.net +#127.0.0.1 fbcdn.com +#127.0.0.1 www.fbcdn.com +#127.0.0.1 static.ak.connect.facebook.com +#127.0.0.1 www.static.ak.connect.facebook.com #---------------------------------------------- diff --git a/dotfiles/windows/disable-folder-type-auto-discovery.reg b/dotfiles/windows/disable-folder-type-auto-discovery.reg new file mode 100644 index 0000000..2a024ce --- /dev/null +++ b/dotfiles/windows/disable-folder-type-auto-discovery.reg @@ -0,0 +1,4 @@ +Windows Registry Editor Version 5.00 + +[HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell] +"FolderType"="NotSpecified" \ No newline at end of file
