At this point i am totally hardened to porn and need to go through so many videos to find the right part of the right scene that does the trick for me. With having to go through so many videos, a prime consideration for me to join a site is how quickly i can evaluate a video before moving on.
Different sites have different ways to preview scenes, so I figured i would start this thread to see if people could talk about viewing features of each site. Hopefully the focus will be on the most popular sites, and these will be what most people will want to join. to me, Videobox is the best at this.

View any thumbnail from a static thumbnail of a scene-
I have only seen this at Video box. To me this is the absolute best. When viewing a thumbnail of the video(not a running video) , putting your cursor at a different horizontal point in the video would bring up a thumbnail for that EXACT part of the movie. Clicking on that would bring you to that exact point in the playing movie. I found this incredible useful. This is different than what most sites have in which when you are playing a video you can look at a thumb of any point in the video. For video box you could look at ten thumbnails (say of ten scenes of a different actress), and for each of those static thumbnails, see ANY thumbnail from any point in that scene, and then click on that to play the video starting at that point. This was the fastest way to look at thumbs from many scenes and finding a particular spot from many scenes.

View pre-selected thumbnail in a static thumbnail of a scene
This is similar to the above, but way more limited. In this, you hold your cursor over a image of a video, and a bunch of pre-selected thumbnails from the video are shown (maybe around 6 thumbs ?). This is useful, but not nearly as good as what is described above(viewing ANY thumbnail in a scene). I have seen this done at several sites, including teamskeet
View any thumbnail from a playing video-
When a video is playing, moving the cursor horizontally alone the "play" bar will pop up a thumbnail of that location in a scene, and clicking will take you to that location. Teamskeet has this as most sites do I think. At this point it isnt a plus if a site has this feature, but a con if it doesn't. This is a must have. A site MUST have this feature for me to consider it.

View many playing videos at once-
Videobox has something called a shuffler i think, where you could apply some filters and it would just show you a scrolling bunch of playing videos matched to those filters, and then you could click on any scrolling by that you found of interest. They could even do that with scenes you have marked as favorites. Cool feature, although i didn't use it much as I would have if they could play videos only of a certain actress. This wasn't available when i had the subscription. I would have loved this.

Downloading Clips instead of full scenes-
Again, Videobox had this, and one net result of this is you could search for clips that other people created (they were tagged, and there were tons of unique tags). I could look at all clips of say "lazy dog", then from a clip i liked, watch the whole scene. This was great because it was the users that were creating the database so to speak.
Jump to one of several defined locations in a scene:
Teamskeet has this. When watching a video, you could click on several links to jump right to that part of the video (missonary, doggie, blow job, cumshot, ets). Very useful.
