Alessandro Roussel visualizes the optical effects and relativistic distortions experienced when falling into a black hole.

What does a black hole look like? Which optical effects appear in its surroundings? What do we see when we cross its horizon? All these answers in 15 minutes! - Introduction - Before the fall - Falling through the disc - Crossing the horizon - Conclusion This video is narrated by Octave Masson.

Awesome. Also, see this great YouTube video of what you would see if you fell into a Black Hole. Is also has a very good explanations of what you are seeing: link to this video

According to this video, the spaghettification doesn't happen until the last few seconds/minutes, when you're close to the singularity. link to this video

On “The Gentle Singularity”

…least until the rate of change of curvature gets so high you're spaghetti, you're (approximately) co-moving with the light from your own body. This means that when you cross the event horizon, you still see your own legs, even though the space the light is in is moving towards the singularity faster than the light itself moves through that space: link to this video…
