Uploading video error with Carrierwave in Rails

I ve tried to upload videos using Carrierwave-video & FFmpeg. I've installed FFmpeg and there is no problem with installation. I have made configurations (I'm not sure from them) from but when I tried to upload video (.mov file), I have an error.

Please help me to fix this problem with Carrierwave & FFmpeg or please guide to me uploading videos to my app with different ways. (Note: I am using Carrierwave for uploading images to my app, and it works perfect)

Thanks for your attention.
