[etika]

version :thumb do
# process :resize_to_fill => [1000, 400]
process thumbnail: [{format: 'png', quality: 10, size: 1000, strip: false, logger: Rails.logger}]
this is the code in video_uploader ,on uncommenting resize to fill gives undefined method error
Please tell how to customize my thumbnail to particular height and width using this gem.
Thanks

Hello

For resize thumbnail install MiniMagic and add version:

    class VideoUploader < CarrierWave::Uploader::Base
       include CarrierWave::MiniMagick
    
       ...
    
       version :small_thumb, from_version: :thumb do
         process resize_to_fill: [20, 200]
       end
 
    end
