Subtitler:Why is the transparency of my titles in Final Cut Pro absent
Why is the transparency of my titles in Final Cut Pro absent / wrong?
Final Cut Pro does not have an option to select the transparency of imported still files. It makes some guesswork and often guesses false and even inconsistely. It's possible that on the same import you may have mixed alpha interpretations. You can however change the alpha interpretation after import. Select the clips and then the menu Modify:Alpha Type:Straight.
