Announced in a tweet, Twitter confirmed that you can now upload your 60fps and 120fps videos as normal with your posts, and they will play back at the right speed.

When the iPhone 5s came out, the 120 fps slow-motion video recording was a great feature, but sharing those videos was tricky. A lot of apps and online services didn’t recognize the videos at their correct speed, and instead played them at full speed.
There’s no need to change settings or anything like that, just upload your video as normal with your tweet, and Twitter will recognize that it is in slow-mo.
