Blurry Video Quality When Copying Clip into Sequence

[#1]

 Hi. I am creating a video and most of my clips are from screen recordings. I noticed that when I cut a clip into the sequence the playback is blurry in some parts even after rendering and exporting. I have never had this issue before using screen recordings, so I am not sure what could be causing it. Please help!!

A screenshot could help. There are options on the Program monitor to control the quality. Full/quarter/etc and also under the Wrench Icon. They are there to help playback when the computer is down on power, etc.

Many users are having issues with VFR. If the file is variable frame rate, use Hand brake to convert to constant frame rate:
