Yes. Almost all video codecs have some generational loss; MPEG is a particularly bad one, unless you use "editable" MPEG (I-frame only). Most Quicktime and AVI compressors, except MJPEG and editable MPEG, also share this trait. However, if your editor is really worth its salt, it won't recompress the entire video, just the cut ends of it. Then the parts that aren't changing can be sent back to the file wholesale. -- Tim Lesher timl@xxxxxxxx
