No more encoding? Screw mpeg/divx.

[DokSoul]

With the capacity of HD-DVD and Blue-ray HD disks, will we no longer have to encode home video? Anticipating their capacity of a min. of 15GB, I could store the 10-15min of uncompressed video. 10-15 min. is about all the home video a person can stand at one sitting. Presently I burn multiples mpeg2 compressed events with menuing to a single dvd in dvd format. Problem appears presently that there are no DVDplayers to play the AVI-DV. So I'm hoping future HD players will play uncompressed AVi-DV. I find encoding and editing with todays software somewhat a pain in the butt. Why encode at all and add artifacts and limit future editing possibilities? Any mpeg encode is lengthy, even more so when you go for quality...and divx and mpeg4 take forever.

Hello,

Seems doubtful they'd let you just plop the uncompressed video on the next gen dvds without doing ANYTHING to them.....

Besides if you have a new enough pc encoding takes hardly anytime - and that's why I bought a wintv pvr250 a few years back. It caps straight to mpeg1/2 so all I have to do is author it

Well, I think I'll wait and see the first commercial HD-DVD-ROM before I start speculating over -R/RW... I guess at that time, I have a Pentium VI @ 12 GHz, well suplied to encode to any format at a higher rate than my HD-DVD writer can write...

You want uncompressed video support or support for DV?

[BJ_M]

DV is not uncompressed ....

you will still have to encode no mater what unless you want only a few minutes on even a HD-dvd ...

What is the max bitrate allowed on the HD-DVD?
I read somewhere something like 30 mbit/s max and if this is the case then you still must compress to be able to watch it because the player won't play it otherwise. But a HD-DVD-ROM may be able to read faster and then you may be able to play it on a computer.

Sometimes I store DV on DVD-R and to play it directly from the disc the DVD-ROM must read with a speed of at least 3X. With good quality discs and a fast reader it is possible. But as said above, DV is still compressed.

I didn't get that - If 30 mbps is what is in the specs, then you must be able to play it at that bitrate?

I love encoding... It's my Hobbie!

Here's a few more observations to justify my opinion:

DV records about 1 hr in 13GB. So on a 4.6GB dvd you can encode approx. 20 min. With a HD disk capable of 15-20GB one side, you could boar your viewers to tears with high quality AVI video.

Yes, DV is compressed. What I'm talking about here is not doing any more damage or degredation to your original captured film.

I would think that if the HD dvd player industry wanted to allow us to play DV-AVI on their players, then they could add the firmware and hardware capablities to do it. May just need a firmware change.

Anyhow, don't like all the dialogue on different codecs and which is best. There is no real answer to the best apparantly because of the good ones, it gets very subjective.

Enter divx. xvid and meg4, the players are in their infancy. Many just don't deliver what they promise..just like the codecs.

The reencode times from DV to other formats would become unncessary.

It's much easier to reedit DV-AVI than Mpeg2 or Meg4.

You could save alot of money by just using virtualdub to record and edit your avi's, i.e. that is no $100-500 editing software is needed.

Anyhow, everyone needs to pick their own path. I know what I'm going to do.

Yes, but 30 mbit/s is lower than uncompressed video and then I must compress it to max 30 mbit/s to be able to play it. I was comparing the max bitrate of HD-DVD with the bitrate of uncompressed video.

I think DV is somewhere around 30 mbit/s but DV is not the same thing as uncompressed video. It would indeed be very nice if we could have HD-DVD players with DV-AVI support because the bitrate may be within HD-DVD specifications.

Ah - OK!
