DVD+R discs don't hold "half an hour" of MPEG video. They hold 4.7G, and how much time that is depends entirely on the bit rate. There isn't one standard bit rate that everybody uses. In order to fill a DVD in half an hour you must be using a bit rate of about 20Mbps, which is almost certainly *much* too high. Many decoders won't even operate properly when fed such a high-rate stream; I think the spec sets a maximum of about 10Mbps. Commercially published DVDs routinely fit several hours on a single regular-density 4.7G disc, with bit rates as low as 2Mbps. Try reducing your bit rate by a factor of at least five. Is it possible you're estimating based on the space consumption of uncompressed video, or the output of some kind of camcorder that does some other kind of compression, like DV? -- Matthew Skala [email protected] Embrace and defend. http://ansuz.sooke.bc.ca/ _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
