On Tuesday, Vine posted a thank-you message and video to its users on its blog and Twitter stream.
"Thank you for sharing so many wonderful videos on Vine," the developers said in a tweet. "You're all awesome."
"Over the next few weeks, we'll be introducing some exciting new parts to Vine," developers recently said in a blog post. "This is just the beginning."
Offering more features to better compete with Instagram could be a motivating factor. "There is no doubt Twitter will move quickly to up the ante on Vine, and this could undercut Facebook's efforts with video on Instagram," said Ovum analyst Eden Zoller.
Instagram video "is going to create a leapfrogging competition between Twitter and Facebook to create a service that is not only easy to use, but also create videos that are high quality and enjoyable to consume," said Forrester's Reiss-Davis.
But the next step isn't about focusing on video length or number of filters -- it's about offering an easy-to-use service that ordinary people who don't live in the Silicon Valley bubble will want to adopt, Reiss-Davis said.
"It's not competing on things like 12 filters or three filters," he said. "It's, is this going to be really easy to use?"
Instagram video was announced Thursday morning at Facebook's headquarters in Menlo Park, California.
