I just got around to trying that a couple of days ago and it produces great output: fast, small file size, and no noticeable difference in quality between the mpeg and the original dv! (I watched many different clips many times over to make sure! on TV and on my LCD) But: the mpeg doesn't seem to scale right. My laptop display is 1680x1050, and hence the original dv output (4:3) has black edges on each side, but the converted mpeg plays "stretched", so that everybody looks fat! Is this just a _player_ issue, or is it a problem with the encoding of the mpeg itself? I noticed the command line has aspect=4/3 in it already, which is the aspect of the original dv file... many thanks! -- Iain Buchanan The first 90% of a project takes 90% of the time, the last 10% takes the other 90% of the time. -- gentoo-user@gentoo.org mailing list
