Choppy video and delayed audio

[tanyas89802603]

I have a project where I'm breaking up a panel dicussion into clips.

The footage I downloaded was an MKV file which I then converted to Mp4 so I could edit in Premiere. 

But the footage is supper choppy. It has the same look as when you speed up a clip and the audio seems a bit delayed. 

I'm still fairly new to editing and I've tried to find a solution but so far nothing has worked. I'm thinking maybe it's somthing to do with the frame rate? Any suggestions appreciated.

2) go Preferences > Audio Hardware > Default Input => select "No Input"

If nothing above helped, download Handbrake tool and transcode the problem file as CFR (constant framerate)

Thank you for all the suggestions! In the end I used Handbrake to get a constant frame rate.
