My garbage man hit my mailbox and I want to send the video to the company. I used the red and green sliders to pick the section I want but after I export it, the playback is slower. My 4 min clip turns into an 8 min clip that is running at half the frames? I clicked the configure box in the export section to see if there was something I should change but I'm not sure what. How do I export an exact copy of my clip?
