Exporting Glitchiness (not exporting most of the video)

[AlexTech01]

So I tried to export a sequence and it exported 30 seconds of a 20 minute sequence. What is going on?

I don't know...  maybe if you gave us a little more information, we might have some ideas...  (sorry for the snark... but)

Please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card

and your source properties and sequence settings would also help.
