FFAStrans wiki

This encoder will output uncompressed audio/video.

Colorspace

Sets the colorspace of the encoded video. If "None" is selected, the node will output audio wave only.

Video size

This option will scale the output video to the defined size. At default FFAStrans will take the input width and height variables of the source video and apply it to scaling. Note that interlaced aware scaling are automatically taken care of.

Pixel format

Sets the bit depth (RGB) or sampling precision (YUV) of the selected colorspace.

Framerate

Force a different framerate than the input media. Default is to use the same as source.

Resizing

Sets the resizing method for how the source should fit to the output size.

Full processing will process (scale, re-interlace, color convert) etc. and re-encode the video.

None, transwrapping cause FFAStrans to try and copy the video stream as is. It will check for some key properties that fits with the selected profile. If the stream cannot be copied FFAStrans will throw an error.

Transwrap when possible cause FFAStrans to try transwrapping. If it fail, it will do full processing.

Video range

Sets the video range of the output.

Same as source implies no change and the encoder will forward the range from the input.

Set to full/limited will just set the video range metadata.

Convert to full/limited will convert the input to set value. If input range is same as output no converion is being performed.

Apply LUT or automatic tone mapping

Enables using a LUT in the conversion. This option also support using a custom by setting using a variable representing the full path to a .cube file. Variables representing any of the available inbuilt LUTs is also supported.

Set start TC

This option field sets the start timecode of the video. By default FFAStrans will use the %s_start_tc% variable from the source video but can be changed to other variables or just static timecodes.

Wrapper

Sets the wrapper on the output media.

Discrete tracks

Sets the number of audio tracks/streams of the output file. One track can have one ore more channels.

Source channels as tracks

This setting will distribute all source audio channels into discrete mono channels.

Same as source

This settings will make FFAStrans try and create the exact same layout as the original media.

Total channels

Sets the total amount of channels the output file holds. The channels are evenly distributed among the available discrete tracks defined. Regardless of the original layout, all audio channels are mapped to separate audio sources. Based on this, FFAStrans will map these sources to match selected audio configuration.. If the audio source has fewer channels than the output then the rest will be filled with silent audio.

If you select "Custom channel mapping" in the "Total channels" drop-down, FFAStrans will enable setting custom mapping per audio track:

Set custom mapping

This will open a separate window displaying all discrete track selected in the "Discrete tracks" drop-down.

For usage and how to configure press the "?" button in the "Custom audio mapping" window.

Audio codec

Defines which uncompressed audio codec/type to use.

Bit depth

Sets the bit depth of the output audio.

Samplerate

Sets the output sample rate of the audio.

Conform volume

Use this to conform volume level to specified level. For this to work you MUST have a variable table from a previous analyze in the "Loudness"-node. You can also use this option to normalize audio by using the peak levels from "Loudness"-node. Maximum level is 0 dB.
