Hello!

Thanks for contacting Wowza Forums!

What are you keyframes set to on the incoming stream? Here is the article on chunk duration. Scroll down to the Property Details section and read on how keyframes and chunk duration need to line up to get the correct output: [ARTICLE](https://www.wowza.com/docs/how-to-configure-apple-hls-packetization-cupertinostreaming%28cupertinostreaming%29#mgrlive)

Here is another forum post that has some information on this: [HERE](http://community.wowza.com/t/-/40042)

Regards,
