Select MPEG for captures

MPEG is a “quality” lossy compression because you can compress the capture dramatically, but still maintain an acceptable image quality. Monday, June 18, 2001 Select MPEG for captures MPEG is a “quality” lossy compression because you can compress the capture dramatically, but still maintain an acceptable image quality.

If the thought of huge video capture files makes your head spin, try capturing to the MPEG format. MPEG is known as quality lossy compression because you can compress the capture dramatically (as much as 200:1), but still maintain an acceptable image quality. In many cases, your capture software will actually let you adjust the amount of MPEG compression through a slider. If you want the best looking video quality, keep the MPEG compression low (i.e., 10:1). If you just want the longest recording time and quality isn’t so important, increase the compression (i.e., 100:1). Remember that high compression may “wash out” fine detail.
