Fraps (derived from frames per second) is a benchmarking, screen capture and screen recording utility for Windows. It can capture from software that uses DirectX and OpenGL, such as PC games. ==Operation== Fraps is proprietary and commercial software, but it is free to use for frame rate display and benchmarking, and free to use with limitations for video capture (30 second time limit, watermark) and screen capture (BMP format only). Because of the way it captures the screen contents, Fraps needs to run with administrative privileges. The ''frametimes'' benchmark feature (logging of individual frame render times) gained attention in 2013 on computer review sites in debate about micro stuttering in games.〔(【引用サイトリンク】title=As the second turns: the web digests our game testing methods )〕 On Windows Vista and Windows 7, the desktop can be captured if Windows Aero is enabled. Windows 8 game capture works, but not desktop capture as of version 3.5.99.〔(【引用サイトリンク】title=Record Windows 8 desktop )〕 Fraps records video at high resolution if the computer is sufficiently powerful. The maximum supported resolution is currently 7680×4800.〔(【引用サイトリンク】title=Fraps FAQ )〕 Fraps uses a proprietary codec. Therefore, playing Fraps video output requires Fraps or ffdshow to be installed. Compression is relatively low and the resulting file sizes are relatively large: A two-minutes-long screencast of a full HD screen (1920×1080) may take up 3.95 GiB on disk.〔(【引用サイトリンク】title=Why should I encode my videos? )〕 There is an option to encode the RGB value of every pixel, but the default is to use a YUV scheme for better compression.〔(【引用サイトリンク】title=Fraps )〕 The color space used is Rec. 709, full range.〔(【引用サイトリンク】title=Fraps discussion (quoted email from Fraps developer) )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Fraps」の詳細全文を読む スポンサード リンク
