So, incase it wasn't obvious, the two images that were tweeted are different.
The first one they tweeted had weird hue blocks in it (as discussed earlier). The second one doesn't have those, only the flame. The flame is definitely added after though as you can roughly see the outline of the area layered on top for the flame by increasing the saturation on the second image.
Still no idea about anything else with those.
As for the video, I think it just flicks up at the point for the sake of the thumbnail image on YouTube.
