Status: Was a member approx. 1 month prior to this review.
Pros: 1. Underlying videos are often high quality in terms of the actual scene itself. It is unfortunate that what appears to be deliberate poor video encoding is used to ruin the quality of the content.
2. The majority of the ZTOD catalog from
2008 on is available (although scenes are substituted - see below)
Cons: (please keep in mind these cons are for a throttled user that the site is trying to encourage to log off with poor quality and bad user interface. A user who logs in for 10-30 minutes every couple of days will likely get another experience)
1. Exhibit high usage and the site "upgrades" but the copyright notices are years earlier. The "upgraded" site will lack search capabilties and will not display dates of videos, names of performers or videos or allow multi-category searching.
2. Throttling is present. The slower the site will get and videos will disappear.
3. Downloads - particularly 1080p - are encoded in ways to make bloated, poor quality mp4.

Technically, >20 files checked the ratio of P (prediction) to I(key) frames was 19:1. A typical ratio is 2:1. I frames aka key frames are the actual images while p frames are the compression. During action the key frames shrink making details too blurry to see. Expect most downloads to be poorer than DVD quality.
Bottom Line: If you are the type of person who just wants to get online and view a video or two to get off, then long off, and don't intend to download anything this site could be for you. The quality should be great.

But if you like to download or watch for hours on end prepare to be throttled severely and to find the videos you download are severely color distorted and bloated.

porn9 (2) Another method of reducing quality while keeping files large I've seen on multiple sites is "pan and zoom" manipulation. This is used on ZTOD and involved what appears to be the camera man moving. But upon frame by frame analysis the direction of movement does not matche the perspective changes.

For example. The Camera is moving to the right, but looking at an actresses arm in ratio to a further away object like the headboard it is obvious that the camera isn't actually moving or shaking. This extra movement consumes valuable bits (since portions of scene come in an out of frame).

I have videos encoded at one-sixth the size of ZTOD movies that are far better quality. This isn't to say all videos are bad from the site, but the quality will change if you are more than a casual user, and the UI is setup so you never can see the end of a video - and the beginnings are typically encoded well.

Thanx for your recent review. You`re obviously about 10 light years ahead of me, regarding the various technical aspects of a site. . .I was on this site for 3 months last year (April-June). Usually, I spent a couple of hours a day, viewing and downloading. I probably DL`ed 150-200 scenes. . . Never saw any "Upgrades" or "Downgrades". . .Never had slowing site problems, or disappearing videos. . . All my DL`s (no 1080`s) look as good, if not better than those from other sites. Has the site changed since last year? Or am just too dense to have noticed all this?
So, if you take a moment to explain what you meant by 1) a throttled user; 2)an upgrading site, 3)disappearing videos; and 4)how does the quality change if you`re more than a casual user?. . .Please dumb-down your answer into layman`s terms so I might understand it. Thanks.

You are right, we have just finished the new encoding scheme using latest ffmpeg and settings and its far better.

We will be re processing all the old content in the new few months and it will all be reduced.

As for speed we have no throttling anymore and its on Highwinds CDN for all streams and downloads.

If anyone has any problems please let me know asap.
