looks after editing

Please can someone tell me what to do. After editing on final cut pro x and export it to youtube I lose all my color correction I did. I bring down the file size to MB but still it doesn't really look good. I use a full HD camera good light while am filming. please someone help me thanks

Try importing into iMovie and exporting back out and then upload to YouTube.

I know this might sound crazy to ask. how can I export to iMovie? from final cut pro or directly from my folder to iMovie?

Same way you'd import into Final Cut. Open iMovie, import the file you exported (saved) from Final Cut and then export back out using whichever setting (HD, large, small, etc,) you wish. Upload to YouTube. Should work.

Whenever I uploaded after exporting from Final Cut, I always had color and/or audio problems. Exporting through iMovie and then uploading fixed this.

thank you very much. bless you
