All-

Was cleaning out some old CD's today and ran across a copy of an original ME-262 training film that I downloaded a year or so ago. It's dubbed into english and pretty interesting to watch.

I'd love to share it with everybody but there's a major problem; it's 51 minutes long and 517 mb! If someone can tell me how to shrink it to a managable size I'd be glad to share.

Cheers,

Brandon

The most effective ways to reduce the size of a digital video are:

1) lower the frame rate (not ideal, but offers significant size savings)

2) resize the video, dimension-wise (offers best overall size savings, since a 2 fold decrease in dimensions will decrease a video's data footprint nearly fourfold. De-interlace the video first, if possible, or you may end up with some unwanted artifacts)

3) lower the audio quality (voice audio need not be very high quality. Going from stereo to mono helps significantly)

Probably the easiest and most economical file format for a PC user without movie editing software would be to import it into Moviemaker (which ships with XP) and convert it to a WMV.

BTW, if the native video format the video is in is MPEG, life is more complicated. You will need to demux the video and audio tracks and then recombine them.

There are a variety of freeware tools out there to accomplish this.
