Hypercam can save your recorded video in a raw form, such as an uncompressed DV-Video file, which will provide the highest possible audio and video quality at the cost of a very large file size. Raw video is extremely large and can take up several gigabytes of hard drive space for a short video clip. Uncompressed digital video is not recommended for use other than in professional video production.
Whether chatting live with a friend, or recording a walk-through for your favorite video game, you can record and playback everything happening on your Windows-based computer with Hypercam. Like many video processors, Hypercam gives you the option of recording raw video, or encoding your video with one of many video codecs. While there is no one right choice in video codecs, how you intend to use your video will determine which video codec is right to use.
Raw Video Processing
An answer to the large file size of the raw digital video is the lossless codec. While still considerably large, lossless codecs such as Quicktime and HuffyUV produce high-quality digital video, compressed into a more manageable file size, that retains all of the recorded frames in the video. Maintaining the frame rate of your digital video is especially important when using a digital video editor or special effects software.
While lossless codecs provide a high-quality video suitable for video editing, once you have completed editing your digital video project and wish to share it online, you will want to choose codec that can provide a good picture quality, while drastically reducing the file size of your video. Many digital video files are filmed at 24, 30 or 60 frames per second, depending on your video recording preferences. Lossy codecs work by removing frames of digital information from your video files.
Popular choices for raw video files include the DV and AVCHD file formats. Lossless codec choices often compress digital video files to the MPEG-1 or MPEG-2 file formats and include Quicktime, FFV1 and HuffyUV. Lossy file formats include file types that are commonly used on portable media devices including Windows Media and MP4. Cinepak, MJPEG, DIVX and it's open-source competitor XVID are common choices for Lossy video encoding.
