You're encountering this because Paperclip was originally built to
process a file into different sizes of itself, original, medium,
thumbnail etc. In that scenario the format stays the same, so if you use
a jpg you'll have a thumbnail jpg as well.
When you're looking at converting to a different format or, in your
case, capturing a still it doesn't check the mime-type for every style
it has. There is at least one branch on github where somebody has
attempted to solve this, but here is the approach I've followed:
1. Create an initializer at
# config/initializers/paperclip.rb
Paperclip.interpolates :style_extension do |attachment, style|
default = File.extname(attachment.original_filename).gsub(/^\.+/, "")
case style.to_s
when /theora/ then 'ogv'
when /still/ then 'jpg'
else
default
end
end
2. Use that interpolation in your url and path options:
:url => "/uploads/products/:basename:suffix.:style_extension",
:path =>
":rails_root/uploads/products/:basename:suffix.:style_extension"
For reference on interpolations:

Hope it helps!
