ScreenPressor

ScreenPressor is a lossless video codec designed specifically for video screen capture (screencasts). It provides unprecedented compression ratio while keeping 100% of original information. Quality of lossless compression makes ScreenPressor perfect for use in online video conferencing and webinar applications. It's probably the best technical solution for video tutorials, presentations and instant screen (desktop) sharing.

  1. What is it?

ScreenPressor is a video codec designed specifically for screen capture. It is lossless which means it keeps 100% quality keeping all your text and graphics crystal clear. It provides very good compression on typical screen capture content (windows, text and simple graphics) but not so good on photos and natural video.

  1. How to install it?

For 32-bit (x86) version you can either run ScreenPressor4_x86install.exe or open the x86_version folder, right click on file scpr.inf and choose Install.

For 64-bit (x64) version open the x64_version folder, right click on file scpr64.inf and choose Install.

  1. How to run it?

Like other codecs, ScreenPressor is not a standalone application which you can run from menu or desktop icon. Rather it is a component used by video capture and editing applications and players to compress and decompress your video. To capture screen with ScreenPressor you'll need a video capture app like CamStudio, Camtasia or WinCAM. To recompress already existing video with ScreenPressor you'll need a video editing app like VirtualDub or Video Enhancer. To play video compressed with ScreenPressor you may use virtually any video player in Windows.

  1. How to configure it?

When using ScreenPressor in a video capture or editing application select ScreenPressor from the list of codecs and press Configure button (which is usually present in most codec selection dialogs). You can also configure ScreenPressor by running spconfig.exe from ScreenPressor folder.
