Those of you who make screen casting videos would know how time consuming it is to make one. After you finally make a screen cast video successfully, you then have to edit it in Premiere Pro. How big of a disappointment it would be if, once you imported it, the video doesn't work?
That's exactly what happened to me. I imported a screen cast video into Premiere Pro, and then when I'm playing the video inside Premiere Pro for editing, half of the frames are greyed out and glitching as I play the video. You can see it in the first couple of minutes of this video for what it looks like.
The way to fix this, however, is quite simple. I just had to export it first in Premiere Pro using certain settings, then re-import the previously exported video, and it worked. What is the reason for this? It could be that the export process re-encodes the video better into a format that the in-program video player can better process, so it doesn't get glitched out. Hope this helps!
