Comment:
Ok, I can see that it is not. You should try creating the file with
uncompressed audio this way:
ffmpeg -i trailer_1080p.mov -ac 2 -acodec pcm_s16le -vcodec copy -af
atrim=end=32.48 trailer_uncompressed.mov
Now the length of audio and video should be the same (you can check with
mediainfo). Decklink output looping (NO -re option!!!) should now just
work.
