Settings

The best way to understand the settings file is to Google search everything you don't fully understand.

However, here are some basics to get you started. Things that aren't mentioned here can be gone through by yourself, but this will get you started on your way.

You can learn more by:

• Entering either the x32 or x64 folder, type cmd into the URL bar at the top, and hit ENTER to open Command Prompt in the current folder. (Or open Command Prompt, type cd and enter the full folder directory)
• Then, typing "nv" and hit TAB to enter either "NVEncC" or "NVEncC64" automatically. Press SPACE and type either -h or --help, and hit ENTER to read the full help file. This includes everything the command will run.

The quickstart guide:

1. Open settings.cfg with a text editor of your choice. Some are mentioned on the Getting Started page.

You will see 2 types of lines in the file:

• "Option=Value" Where settings are given values
• #Here is some helpful info Lines starting with # are ignored by the program

These are the variables you'll be changing. You don't need to change any other file except for this one.

• OutputFormat Sets the output file format. Example: mp4
• CopyAudio Chooses to copy audio (will keep format, disable if errors or incompatible a/v formats). Default: 1. Set to 0 to use a custom audio codec (Use AudioCodec below), or no audio in output.
• AudioCodec Chooses an output audio codec (Only use when audiocopy is 0). Default: BLANK. Example: AudioCodec=aac
• Suffix Set your output file's suffix. _Proxy is the default. Setting it to _Proxy will transcode test.mp4 into text_Proxy.mp4 (Or the format you set above) -- This is Adobe Premiere Pro's default.
• OutputDirectory Sets the output directory. Blank by default. Leave it blank will save your transcoded files to the input file's folder. Example: D:\Documents
• Resolution Sets the output resolution. 640x320 is default. Example: 1280x720
• FPS Sets the output FPS. 60 is default. Example: 30
• VideoCodec: Sets the output codec. h264 is default. Example: h264
  • To see what arguments are available, enter either x32 or x64, and run nvencc --check-formats or NVEncC64 --check-formats
• EncoderProfile Sets the encoder's profile. high is default. Example: baseline
• Level Sets the encoder's level. auto is default. Example: 4.2
• Preset Sets the encoder's preset. performance is default. Example: quality
• OutputDepth Sets the encoder's Bit Depth. 8 is default
• CUDASchedule Sets how aggressively NVEncC will use your CPU. spin is default, and is the most demanding. NVEncC's default is sync
• SampleAspectRatio 1:1 is default.
• Lookahead Sets the number of frames NVEncC looks ahead.
• GOPLength A higher number has more compression, but less quality. 0 is default.
• BFrames: Sets the number of consecutive B-frames. 3 is default.
• ReferenceFrames 3 is default.
• MVPrecision Q-pel is default (and the highest quality). Other options are half-pel and full-pel, decreasing in quality in that order.
• Colormatrix Sets the Colormatrix profile. undef is default.

h264 specific variables

Make sure to set these to OFF if you're using HEVC or another codec.

• CABAC 1 uses CABAC. Blank does not add --CABAC flag. 1 is default. 0 if you're using a different codec.
• Deblock Adds --deblock filter flag. on default. off to use --no-deblock flag. BLANK if you're using a different codec.

Variable Bitrate Settings

• Bitrate Sets the bitrate, and/or encoding mode. cqp 15 default. Can change to vbr 3000 for a 3,000 Kbps VBR file, for example. See settings.bat for more info.
• VBRQuality If using VBR, enter a value, otherwise leave it -1. Set to a VBR target quality between 0 and 51.
• MaxBitrate Sets the max bitrate, when using VBR. Leave it -1 when not using VBR.

Optional extras

• GPU Manually set which GPU to use. BLANK by default, will pick the best card to use automatically.

To see which cards you can use, run the command "NVEncC --check-device" or "NVEncC64 --check-device", or run the program with the -d or --devices flag.

• OSBit Manually set Windows x32 or x64 here. BLANK by default.
• OtherArgs: Set other arguments to be appended to the end of the command string here. BLANK by default.
• Override OVERRIDES EVERY SETTING PRIOR EXCEPT FOR OTHERARGS This lets you set everything yourself in the string here. Only do this if you understand what is being run. The program will only add the input and output files, as well as pick the right NVEncC encoder (x32 or x64). Everything entered here will be stuck right on the end of the string, to be run by the encoder. Default is 0
• DeleteOldQueue Deletes queue once it has been processed, instead of renaming it and keeping it incase something was missed (default is to keep). Setting is 0 by default.
• AfterCompletion Runs a command after a file is processed (happens with every file that is run. Every variable in TcNo-Transcoder.bat can be used here, but the one you'll likely use is %outF%, which is the output file of the transcode. For example: AfterCompletion=ffmpeg -i "%outF%" "%outF%.mp3" will be run as ffmpeg -i "D:\Videos\p_Proxy.mp4" "D:\Videos\p_Proxy.mp4.mp3"
