The Bedrock Edition sneaking animation takes approximately one second to run in its entirety. This is more than 6 times slower than the Java Edition sneaking animation, which takes approximately one-sixth of a second to complete. The Bedrock animation eases out ridiculously slowly, and additionally shifts the view about 40% lower than Java's.
