  { value: '-f', tip: 'Force output file format.' },
  { value: '-y', tip: 'Overwrite output files without asking.' },
  { value: '-n', tip: 'Do not overwrite output files, and exit immediately if a specified output file already exists.' },

  // Filters.
  { value: 'scale', tip: 'Scale (resize) the input video, using the libswscale library.' },
  { value: 'deband', tip: 'Remove banding artifacts from input video. It works by replacing banded pixels with average value of referenced pixels.' },
  { value: 'deflicker', tip: 'Remove temporal frame luminance variations.' },
  { value: 'deshake', tip: 'Attempt to fix small changes in horizontal and/or vertical shift. This filter helps remove camera shake from hand-holding a camera, bumping a tripod, moving on a vehicle, etc. ' },
  { value: 'dejudder', tip: 'Remove judder produced by partially interlaced telecined content.' },
  { value: 'removegrain', tip: 'The removegrain filter is a spatial denoiser for progressive video. ' },
  { value: 'vaguedenoiser', tip: 'Apply a wavelet based denoiser. It transforms each frame from the video input into the wavelet domain, using Cohen-Daubechies-Feauveau 9/7. Then it applies some filtering to the obtained coefficients. It does an inverse wavelet transform after. Due to wavelet properties, it should give a nice smoothed result, and reduced noise, without blurring picture features.' },
