At the top of a VideoSurf results page for ‘Mad Men,’ users can search for clips featuring specific characters.

This week I tested VideoSurf.com, a site that claims to be the first to search videos by “seeing” images that appear in these videos. The company says its technology can analyze a clip’s visual content, as well as its metadata — especially when searching for people. VideoSurf has analyzed and categorized more than 12 billion visual moments on the Web to understand who the most important characters and scenes are in a video, and it uses this knowledge to sort clips according to relevancy.

Search results on VideoSurf spread out videos in a filmstrip-like format, distinguishing one scene from the next. Users can choose an option to show only faces, which helps if you’re looking for a specific person in a long video or movie. And when looking at videos from certain sources, you can select a scene from the filmstrip and jump ahead to that scene rather than sit through the entire clip.

When it works, VideoSurf is one of those technologies that make you wonder why someone didn’t think of it sooner. The site aggregates content from about 60 sources, including YouTube, CNN Video, Hulu, ESPN and Comedy Central, and a sorting tool weeds out unwanted results like the irksome slideshows that are labeled as videos. VideoSurf can find videos on all kinds of subjects, but it really shines when it finds well-known people.

But VideoSurf has some rough edges and doesn’t always work as it should. In its defense, the site is still in its public beta, or trial, stage, and plans to be full-blown by early next year. Right now, one of its best features, the ability to jump ahead to specific scenes, works with video from only a handful of sources including YouTube, MetaCafe, DailyMotion and Google (GOOG) Video. Videos from Hulu.com confusingly allow jumping ahead only from certain screens.

Additionally, I came across a couple of videos that were no longer available, though they were listed in search results. And a customizable VideoSurf home page for users with accounts on the site saves searches but not specific clips; VideoSurf plans to fix this next week by adding a favorites page where users can store and share favorite videos with others.

Still, I really grew to like VideoSurf’s clear way of displaying content that would be otherwise buried within videos. Rather than trying to guess a video’s contents by looking at a single representative image, VideoSurf’s filmstrip views showed me exactly what I’d be watching. In many cases, I viewed a video I might not have otherwise watched because its filmstrip showed shots of scenes that looked interesting.

On the left-hand side of the search-results page, VideoSurf users can narrow results according to Content Type, Categories and Video Sources to see just what they’re looking for — or, often more important, what they’re not looking for. Content Type, for example, includes slideshows, Web series, full television episodes and full movies; a search can include only videos in a particular category (say, slideshows) or exclude that category altogether by unmarking the box beside it.

Most search-results pages include tiled still images at the top representing the characters in the videos. By selecting one of these characters, users can refine search results to show only videos with that character. For example, I typed the title of a favorite television show, “Brothers and Sisters,” into the search box and saw the names and images of seven actors on the show at the top of the screen. I selected Sally Field and was redirected to results of videos featuring only the mother she plays on the show.

I used VideoSurf to search for Beyonce’s “Single Ladies” music video, and then changed the date parameters to find only videos posted this week. This retrieved a Saturday Night Live skit in which the pop singer spoofs her own video with help from three men in tights — including Justin Timberlake. While the SNL skit ran, a list of related videos appeared in a column on the right, including clips of J.T.’s past SNL skits.

Occasionally, annotations appear on videos, but these come from the source — not VideoSurf. If overlaid text appears on YouTube videos, it can be turned off using an icon in the bottom right of the YouTube screen. Video-sharing sites that use introductory pages such as pre-rolls before each video will still show those pages.

VideoSurf makes it easy to send specific clips of videos to friends. I did so by selecting a Share option and adjusting slide bars to trim the clip to start and end at scenes I preferred. Clips shared with friends via email are sent with the VideoSurf filmstrip, giving others the ability to also know what the video will include so that they, too, can discern whether or not they want to watch it.

Clips can be shared on social-networking sites like del.icio.us, MySpace and Facebook, though VideoSurf’s helpful filmstrip didn’t show up on these sites like it did in emails.

I also tested an add-on for the Mozilla Firefox browser called Greasemonkey that works with VideoSurf. When installed, this displays VideoSurf’s helpful filmstrip beneath search results from Google Video, YouTube, Yahoo (YHOO) or CBS.com (CBS). Once installed, filmstrips illustrating important scenes appear along with the normal text results for videos, and some of the filmstrips enable jumping ahead to specific scenes. This somewhat techie Greasemonkey extension can save people the extra step of making a separate visit to VideoSurf.com to watch a specific clip.

VideoSurf uses smart technology that can save people the aggravation of watching videos that aren’t what they appear to be. Since so much Web content now includes videos, a visual search tool that can better assess videos like VideoSurf is a good idea. When this site improves its now-flaky ability to jump ahead to specific scenes in videos, it will be even more valuable.

One way to find the information you want is by setting up computer-generated alerts. These electronic notifications are relatively simple to use and offer a range of helpful services, from a virtual heads-up when your name is mentioned online to messages about a product’s price suddenly dropping.

For years, I’ve used Google Alerts as a way of keeping track of myself online. If my name is mentioned in a blog or if this column appears on the Web, such as on the site of a newspaper that syndicates it, a Google Alert sends me an email about it. Google Alerts can work for you to find a variety of things, such as telling you if a video of a favorite band popped up online or that a blogger posted something about last night’s episode of “Mad Men.”

In about a month, Google will begin delivering these alerts to users via feeds, as well as emails. Google (GOOG) certainly isn’t alone in the alerts arena, as Yahoo (YHOO), Microsoft (MSFT) and AOL (TWX) are also players. This week I tried two small companies that recently joined the mission to help users find the Web content using alerts.

Pinpointing Searches

I tried Alerts.com and Yotify.com, and found worthwhile features in both. While Google Alerts does a good job of finding search terms in news, blogs and videos, Alerts.com and Yotify use forms that are a cinch to fill out and let you pinpoint your searches.

Alerts.com offers to notify users via email, SMS text messages or even voice calls to a cellphone or landline. The site organizes your alerts on a personalized Web page and uses a desktop application called Elertz to tell you when an alert has generated results. I liked this site’s flexibility: It not only gave me different ways to receive notifications, but also enabled a variety of options for time-specific deliveries of alerts.

But Yotify has advantages of its own, including the ability to integrate with FriendFeed and Facebook so friends can offer their recommendations or opinions. It also lets users search for event tickets or items auctioned on eBay (EBAY). And a smart preview panel gives you an idea of the type of results your search will return before you submit the request for an alert.

Viewing Results

For now, Google Alerts and Yotify will send alert notifications only via email, though all three services will let you view your alert results online. All three are free, but SMS alerts sent to a cellphone via Alerts.com may not be, depending on your plan.

All in all, I found there were certain things each service was good at doing. For example, Alerts.com lets me know college football scores when I want them: only after the final score; at the end of each quarter and after the final score; or at the end of each quarter, after the final score and after each time a team scores points. Yotify gave me detailed options in a Craigslist search for furniture, including showing only listings with photos or just those that included the word “sofa” in a title; it will even hunt for a specific price range.

For the person who wants to spend minimal time creating basic alerts, Google Alerts will do the trick. These can be narrowed down to show results that fall into the News, Web, Blogs, Video or Groups categories, or you can perform more-blanketed searches using a Comprehensive category.

Alerts.com offers plenty of simple alerts that require only a bit of scheduling to set up. Each alert appears as a widget that can be expanded, edited or deleted with a simple click, and this page has a clean look with attractive, cohesive graphics.

I didn’t care much for Elertz, the desktop component of Alerts.com, because once installed, it notified me of new Alerts data using an irksome star that glowed red until I checked my notifications. Elertz didn’t work properly on my Windows XP machine until Alerts.com fixed a bug.

But Alerts.com’s price watch and price protection alerts are incredibly useful. Price watch looks to see if an item’s price drops into a lower price range, at which point users are notified. Price protection watches to see if products you bought are now on sale so you can get a refund. I tried both, and I’m hoping I’ll hear soon that a specific pair of Anthropologie boots is on sale.

Yotify uses the idea of virtual scouts that scour the Web for specific information. Scout findings can be condensed or expanded in one click, and results can be filtered for more specific findings or shared with friends via Facebook or FriendFeed.

Scout Work

But some scouts took too much work to set up. When I tried to set up a scout for college football scores, I didn’t see a sports category (Alerts.com had a colorful NCAA icon right on its home page). Instead, I had to choose News, then select ESPN, then NCAAF and finally enter “Penn State” in a key word box for my scout. And after all that, the scout offered results only daily or hourly via email.

I would also prefer if I could better organize my scout lists. As it was, all of my results appeared in one list: The NCAA scout was right above the scout that found Obama mentions on Huffington Post, and below that were results for YouTube’s most-watched videos. Yotify says it will add ways to more neatly arrange data in the next month or so.

On average, Yotify returned more results instantly, such as 10 instant Craigslist sofa results compared with Alerts.com’s two in the first few hours.

Overall, these sites are worth trying so you can find which alert system works best for you and stop wasting time searching the Web the old-fashioned way.

Now Shutterfly, a leading online photo service, has integrated simple photo sharing into personalized Web sites, which serve as a more permanent and collaborative place to communicate. This new offering is appropriately called Shutterfly Share (www.shutterfly.com/learn/newshare.jsp), and the sites are free of charge and without advertisements, for now.

Shutterfly Share offers condensed views of multiple photos; Compact View is shown.

Shutterfly created this souped-up arm of its company early this year after acquiring Nexo Systems Inc., a company that makes straightforward, clutter-free sharing sites. Shutterfly Share caters to groups, like families and softball teams, as well as to friends, who use the sites as home bases where photos and news can be posted.

Overall, this site-creating program does a nice job with minimal work on the user’s behalf, though it currently lacks a few useful features and its security-related member permissions when setting up the site can be a bit confusing.

One of Shutterfly Share’s best features is its emphasis on photos, particularly the ability to quickly see multiple images simultaneously on the site’s home page. Various other categories of information dot the page, like links to favorite sites, calendars or team rosters. But Shutterfly Share is still in its beta (testing) phase, and leaves room for improvements, some of which will be made upon its official release planned for Aug. 12. For example, a few features stuttered or didn’t work the first time around. One photo that I added to the top of my page froze when I tried to open it for editing, and embedded video links wouldn’t play during one test.

But some Shutterfly Share faults won’t be fixed by the launch. It doesn’t yet have the ability to upload personal videos; instead, users can only add links to videos already available on a public site like YouTube. Nor does Shutterfly Share have a way to show you when other people last signed on, a feature groups who share Web sites tend to like. The company hopes to fix these two issues by early next year.

I created a site on Shutterfly Share called “middleground” for the purpose of staying connected with a handful of friends in various cities around the country. Our site let us digitally catch up by sharing photos, gossip and general news about one another’s lives. I even added news feeds from my favorite sites at the bottom of the page.

Shutterfly obviously wants users to be able to quickly start a site, condensing this process to just a couple brief steps (the process is made faster if you’re already a Shutterfly member). I chose a category and style for my site; categories included Family, Photo Journal and Baby while styles ranged from yellow lattice to artistic black backgrounds.

Privacy is a priority, for good reason, and I protected my site with a password. But I mistakenly assigned each friend with limited permissions as “Contributors” instead of “Editors.” It turns out that Contributors can view, comment, add and edit their own content, but not that of others; the Editors can do so. After my grumbling friends alerted me to my error, we were in business. Still, too many security options can be confusing during setup.

Shutterfly Share tries to make posting photos to the site as easy as possible by offering various ways to do so — even by simply emailing attached photos to a special address, which could be helpful for relatives intimidated by the process of uploading photos. But every person who adds photos to the site, whether via upload or email, may do so only if he or she is a member of Shutterfly. Though many people already have Shutterfly accounts, this could deter some who just want to add photos without becoming a member of the service. Shutterfly says it will allow non-members to post to the site by early next year.

People who aren’t Shutterfly members but are invited to be members of a Shutterfly Share site (by the site’s owner) can post anything other than photos, including comments, calendar entries and polls.

Film Strip View

Shutterfly Share organizes recent images on the site’s home page using one of seven display patterns, including a really great-looking Film Strip view and Compact view; the former shows a horizontally moving ribbon of photos flowing across the screen while the latter condenses multiple photos into thumbnails so many can be displayed at once.

Up to three large, artistically arranged photos can be shown at the top of each site; I added two shots of my friends (both members of the site) and another of the Washington Monument at sunset. This gave it a personalized and professional feel.

I missed having the ability to post my own videos, but searched for clips on YouTube, Google (GOOG) and Yahoo (YHOO) using a built-in tool that easily adds videos to the site. I posted a scene from the television series “Mad Men,” along with a “Saturday Night Live” skit; thumbnails representing each showed up on the site. I added a calendar on which I noted my birthday, to alert any forgetful friends, and in a Favorite Links section, I added a list of URLs that I like. Every item on the site can be dragged around and rearranged.

Daily emails update members on site activity, such as newly posted photos and comments, so as to keep each member in the loop on site happenings.

When Shutterfly Share is officially released, it will build contextual advertisements into the sites. But early next year, the company plans to offer a premium subscription version of Shutterfly Share that would remove all ads and allow access to special features.

The launch version of Shutterfly Share will also give users the ability to view and digitally page through coffee-table photo books that people have assembled using their digital photos. If you like someone else’s book, you can (with permission) order a copy for yourself.

Shutterfly Share is a step in the right direction for people who want photo sharing to be more long-term and user-friendly than email invitations. And Web sites built with Shutterfly Share deceivingly look like they took a long time to create. When Shutterfly cleans up its permissions and makes posting via email easier, this program will be even better.
