In sort of a companion to the "RLD/Platinum X DVD Problems" thread, I'd like to point out that I've been noticing picture quality issues on other companies DVDs recently.

There seem to be three main issues:
(1) Video that never seems to be in focus. It's watchable, and typically better than VHS, but it is noticeably inferior to what we have come to expect on porn DVDs.

(2) A "blurred halo" effect. There is a blurred halo around performers and some sets/scenery items.
This is particularly annoying when it's noticeable around cocks and faces during cumshot sequences.
I think this is different than the colored halo issues being discussed in the RLD thread (but it could be due to related equipment and authoring issues).

Which leads to...
(3) Blurred video during performer's quicker movements. Again, particularly annoying during cumshot sequences!
For any of you who have experimented with variable bit rate (VBR) vs. constant bit rate (CBR) in capturing and editing your own digital videos, this looks a lot like the "pixel-box blurriness" you get with VBR and lower bit rates when video action first starts to move quickly
following relatively slow or stationary scene movement.

I most recently noticed these complaints on my original DVDs of "Deep Throat This" #14 and #15.
These are noticeably inferior to the quality I've come to expect from Peter North's DVDs!

Do we have a significant bootleg problem now with DVDs?
I'm wondering if the problems I'm noticing might be with distributors selling duplicated DVDs using compression schemes (like the 321 software)?
I checked through my "Peter North" DVDs (God knows which studio or production company each belongs to... LOL) and found all DVDs I checked to be single-layer UDF file formats with about 4 GB on a disk
(Contrast this with my Evil Angel and RLD DVDs I checked which were double-layer "unknown" file formats with about 8 GB on a disk).

It very well could be that Peter's DVDs have always been of lesser quality (bit-rate, etc.) in order to squeeze them onto a cheaper single-layer disk?
Maybe Peter's experimenting with VBR solutions to maximize content on a single-layer disk (instead of popping for dual-layer media)?
Or, Peter might have a serious bootleg distribution problem?

Any one have any insights?

I've seen the colour shift halo on these titles:

Wicked: Space Nuts
Evolution Erotica: Butt-a-bang
Metro/Toxxxic: Pussy Whipped #2
Elegant Angel: Cytherea Iz Squirtwoman
RLD: Teenage Spermaholics
RLD: No Cum Dodging Allowed #3
PXP: Baker's Dozen

Space Nuts especially does not seem like a discount production in any way.

While I can't specifically comment on some of the above titles, I can say with 100% certainty that some of them were authored by the same company that has been authoring PXP's titles. There are also a few from Zero Tolerance and Digital Sin that have the same problem. It's been confirmed to me that Zero Tolerance has recently been using the same company as PXP for some of their authoring. I don't know about Digital Sin.

I think that it's pretty safe to say that this problem is isolated to that single authoring company. Since they have discovered what the problem was and have removed that piece of equipment from their production process. They shouldn't be creating any more bad discs.

The equipment was removed late July/early August. Given the turn around time for DVD's between going to the authorer and hitting the stores, it's likely that the problem will disappear completely by sometime in late Sept/early Oct.

However, that wouldn't necessarily apply to companies who sit on product for a long time before releasing it. I think that Wicked is one of those companies.

So Bill...
If you had to take an educated guess, what percentage of the industry has been affected by this authoring company?

Also, regarding your reference to Wicked sitting on product...
My understanding is that companies typically sit on scenes (not necessarily completed, authored and pressed DVDs).
Wouldn't these scenes be OK as long as the DVDs they find their way into are authored after the "big equipment halo fix of aught '04"?

I'm glad people are posting this topic here away from the drama in an attempt to solve the problem and not start another flame war. I do know a little about transcoding/encoding and the process that an author goes thru.

Here are my question for the Cal44, OREN or anybody else for that matter?

Why arent porno movies encrypted? Seems like a simple solution to make it harder to copy DVD.

Do the studios do a raw edit with uncompressed video? read that as big huge files?

Finally what caused the halo effect? transcoding by authoring company?

EL - The macrovision licenses cost money, therefore the studios would have to pay out for each title. It probably wouldn't be worth doing for them.

" Why arent porno movies encrypted? "

Most production companies install encryptions like CSS codes or microvisions, however a DVD is in quality equal to a DV master. It does't stop piracy. Technology allows people to strip the DVD and re-author it again. The halo effect caused by simply bad encoding process. It can be caused by a bad wire, bad harddrive or cheap encoder or simply adding too much chroma to the colors. It is highly recomended to encode movies in VBR 5.5 or higher rate. Most authoring houses who are operated by young unexperienced kids who always look for shortcuts. VBR takes twice as much to encode than stright encoding. most production companies refuse to pay the extra cost for authoring. They don't want to pay more than 600 dollars for a DVD-9. I guess I can sum it up by saying you get what you paid for.

I have no idea.
I was talking about companies who make features and don't have lots of releases every month. They may shoot a movie and then not release it for a year or more. Vivid is notorious for this. They will often release a movie that is a year or two old.

I also seem to remember there being a very long time between reading about Devinn Lane doing her fiorst Boy/Girl scene and the release of that movie. Because of that recollection and the fact that Wicked uses this particular authorer, I mentioned them specifically.

I have no idea whether they do the DVD pressing closer to the production date or the release date in this instance. If they make the DVD's closer to the production date, and they were made prior to the problem being fixed, then the problem could appear on discs that aren't released until sometime next year. But you're right, if the the DVD wasn't authored prior to discovering the problem, then it will not appear on the disc, regardless of when it was shot.
