As a result, other programs cannot use the overlay (most video-cards only have one), and so videos have to resort to using software-rendering (eg using the CPU instead of GPU) to display the video instead. In Windows 7, the Aero interface occupies the overlay surface to do its extensive fancy looking graphics and transparencies without slowing the system to a crawl. (Have you ever tried to get a screencap of a video and gotten a black rectangle when you pasted it? That was because you captured the overlay surface, not the actual video.) In Windows XP, the hardware-accelerated overlay surface of the video-card was not used by Windows, and thus was free for programs to use to write data directly to the video card’s output. If you can think of anything, please let me know at your earliest convenience.The problem isn’t VLC, or even the drivers it’s Windows, or to be more specific, Aero. Not disappointed with your efforts, though. Maybe my partner whom is relying on presenting somewhat professionally edited videos would be OK with the distortions, but I am very disappointed with the result. The ASUS laptop I tried, with the same results, has a current generation Core i7 CPU and, while it has integrated graphics, I think it is plenty sufficient to handle the relatively basic editing that I'm doing.Īs it is, the very basic issue remains: I'm loading an HD MP4 video and VideoPad adds artifacts. I know my PC isn't new but it certainly isn't underpowered or slow. I sure do appreciate the time and attention you've given me, but as someone whom has been in the software world since the 80's, I find it hard to fathom that there isn't an explanation for this. If something else works, then I will want to get a refund. Or, I'll find a different PC-based software program. I'm going to move the clip there and, if it works, do my editing on that.
