Thanks for posting Neil. There are already several posts on this topic. Here is one for your reading enjoyment.

HDV Bandwidth - is it really an issue?
Just wanted to post my thoughts about this . . .

MPEG2 is a much more efficient (i.e., quality per Mb) compression than DV and its cousins (DVCPro50, DVCPro HD, HDCAM, etc.).

For example, MPEG2 at 8Mbps looks just as good as DV at 25Mbps.

DV wasn't chosen because it was necessarily the most efficient compression method, it was chosen because it was a very efficient in editing. That was of primary importance when computers had not even broken the 1GHZ barrier yet.

I don't think many people will argue that point.

Having said that, wouldn't it make sense that if HDCAM looks great at 100 Mbps, that HDV at 25 Mbps should be pretty dang close?

Just remember when comparing bitrates between formats you aren't necessarily comparing apples to apples.


Graeme Nattress September 12th, 2004 04:47 PM

Comparing codecs, especially bit rates of MPEG2 based ones is very, very tricky. DVD's are usually encoded with 2 pass VBR with a 15 frame GOP, and even then, you'll see artifacts. I don't see the full DVD MPEG bandwidth as being transparent to the source.

HDV is using a 6 frame GOP, so it won't be as efficient as the MPEG2 used for DVDs, but it's also a higher bit rate, and also a higher image resolution, which probably means it will get greater efficiency.

Also, hollywood movie DVDs are often encoded as 24p progressive, which again, is going to give you more efficiency over encoding 30p or 60i.

So not only can you not compare apples to oranges, but you can't even compare types of oranges easily.

The proof, they say, is in the pudding, which means getting an FX-1 in your hands and seeing what the image looks like and moves like, and if there are issues, what can be done to get around them, just as we learned to get around the issues with DV.

Sony Z1 and FX1 various questions 2004 - 2005
Any info re FX1 RGB output

what format & bandwidth?

please anything you find out post here

DVX100 vs. HDR-FX1
in regular DV mode which cam do you guys think will come out on top. I think dvx will because its progressive scan. I would like to see test shots of the 2 cameras take of the same things so we can compare them.

Heath McKnight September 16th, 2004 10:21 AM

That's probably a debate best left to when the camera comes out. Specs say a lot, but the visual says much more.

I thought it was like $3,700????


Rob Lohman September 17th, 2004 07:41 AM

Since that site is in Canada I presume those are CANADIAN
dollars, not US. So that should be around $4125 US.

Difference is probably in tax and import and such.

Will Lumier Import with FCP?
I'm using FCP 4.0...
would I be able to use Lumier to import the Sony HDV cam footage to edit on my mac?
It sounded like Sony is using a different codec.

How many pixels will the DV part of this camera have? Also, do you think it will be better than the DVX. I have the DVX100 and i think it is the most AMAZING picture.

24P Cinema Mode in SD
Anyone know if this simulated 24P mode can be use in SD mode?

Heath McKnight September 27th, 2004 05:14 PM

Not yet on my front.


John Jay September 28th, 2004 10:44 AM

Lets talk about the LSI
Sony Japan site mentions that the LSI is programmed in the C language.

I wonder whether there will be downstream 3rd Party support for this camera such as improved encoding and other goodies and even updates?

could this be the birth of a camera with open architecture?
