Try substitution of another character (using Auto-Replace**) and then rendering.
If the new one continues to blink after rendering, then it's a character issue.
If you still get the same result (No blink), then it could be the "Auto-Blink" isn't set, or the Motion applied doesn't contain any facial animation keys for the blinking.
** Auto-Replace: Choose the current Model in the scene, and then apply a new one with double-click from your library to substitute.
I notice my character stops blinking her eyes a third to halfway into an exported .mp4 video and never blinks for the rest of the video. Her eyes just stays open and no more blinking compared to before. My character is a model I bought from the Iclone store but not sure if that's an issue. So she does blink her eyes earlier in the video then stops the rest of the way. I'm using Iclone 5.5.
