For instance, the program lets you easily merge video files or images, record cursor movements on the screen, and zoom in on visual elements to deliver stunning output files. It lets you work on creative content projects, software demos, online learning presentations, and other similar tasks.
How to create videos on Camtasia?Īmong popular video creation tools available online, Camtasia has become the standard for simplicity, quality, and powerful features. Within a short period of time, Camtasia has become a full-fledged e-authoring tool, assisting teachers, managers, and other professionals with their lessons or presentations. After you’ve completed work on a project, the output files can be directly shared on YouTube, Google Drive, Vimeo, etc. With the mobile version, you can conveniently transfer data or content from your smartphone to the PC program. If you pick the default one, it will not look as good, but if you pick one that looks better (eg blending, smoothing, etc.) it will use more CPU.The development team has also released a free mobile application for smartphone.
You also figured out that you can use the Direct-X output module to use acceleration, but that requires disabling Aero. Of course this is just theory, I have no actual evidence of programs using hardware-acceleration while Aero is running.)Īs you discovered, the software-rendered display looks fairly different from the accelerated display. (Presumably, switching the screen into a full-screen mode, an app can use the overlay, though Alt-Tabbing to the desktop would then cause problems or at the least a delay as the video-card’s drivers are switch. 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. The problem isn’t VLC, or even the drivers it’s Windows, or to be more specific, Aero.
