ZD Recorder

ZD Recorder is a unique software program that can record almost everything displaying on the computer screen, including desktop applications, PC games, various videos (streaming video, flash video, webcam video, DVD video, and etc.), and record audio from speaker or microphone simultaneously.

You can use ZD Recorder to:

* Create demo videos to demonstrate how to do something on a computer.

* Make game movies to show how cool you are in the game.

* Record interested videos to hard disk for later review.

What makes it unique?

Easy-to-use.

Straightforward user interface, simple settings and smart capture.

Universal capture capability.

Most of the other screen recording software on the market can only record those applications use standard rendering technologies, such as GDI and GDI+. If target application uses any special rendering technology, such as Overlay, DirectShow, DirectDraw, Direct3D, OpenGL or etc., they may get nothing because it is hardware accelerated and can not be captured in the common way. Most video players and PC games use special rendering technologies to improve their performance, so few software program can record them correctly. ZD Recorder handles all these rendering technologies and it is the only software program (as far as we know) can record almost all kinds of applications.

Minimal performance impact on system.

Screen recording is not a simple task. It captures a large number of pixel data from screen to memory and then encodes the pixel data into a compressed video bitstream. Simultaneously, it also captures sound data from sound card to memory and then encodes the sound data into a compressed audio bitstream. This process repeats 20-30 times every second during the course of recording. So there is performance impact on system. If the performance impact is distinct, it would be a bad experience, especially when playing a PC game. ZD Recorder is fully optimized to reduce the performance impact on system and does perform better than most of the other screen recording software on the market.

Fast real-time audio/video encoding.

As mentioned above, real-time audio/video encoding is the key task of screen recording. So, efficient codecs are required. ZD Recorder selects XviD MPEG-4 Codec for video encoding and Lame MP3 Codec for audio encoding. Both of the two codecs are fast, stable and classic.

Good audio/video synchronization.

Many real-time video processing software programs may have audio/video sync problem when either audio data or video data is too much for them to handle in real time. ZD Recorder uses a smart algorithm to dynamically skip overloaded data in order to keep audio and video in sync.

Fine audio/video quality.

Optimized capture engine + Classic codecs = Unbeatable audio/video quality.
