HD Media & Data rates at DVinfo.net

It just occurred to me... with up to 50GIGs and HD media & players capable of 54Mbps data transfer rates couldn't our HD-DVD/BluRAY authoring programs just write HDV to the disc with out any additional compression (or convert to the player-readable format without addtional compression)?

The short answer is probably essentially yes. MPEG-2 is a supported compression standard with the new players. It would be surprising if the video stream and audio stream contained in HDV wouldn't be usable without recompression.

Anyone else in this forum "jacked" about the fact that they could just dump 22 GIG worth of video on a disc without another step of compression like we do now with DVD? And that the quality will be better without that extra step of compression?

I'm already jacked on it! I have a Linkplayer2 and it plays the raw files from my HC1 off of plain ol' red-lazer DVDs.

It's SO great to be able to do that ... the 22GB will make it even nicer, although with bigger/longer files it will be interesting to see how navigation is going to be implemented. Playing a raw file doesnt allow for skipping between chapter points etc, so some kind of "authoring" will still be necessary....

Yes authoring will always be neccessary. My point is that we won't need to compress again and that should result in much higher quality from 25Mbps.
