This week, I took a look at just a few Web sites that make finding these videos easy, including Howcast Media Inc.’s Howcast.com, WonderHowTo.com from WonderHowTo Inc. and eHow Inc.’s eHow.com. Howcast.com, which launched in February, encourages users to make and share good-quality, entertaining videos by providing tools on its site, and has about 5,000 videos so far. WonderHowTo.com, launched in January, used a different strategy by aggregating over 110,000 videos from various sources — including Howcast, YouTube and Scripps Networks (SSP) — rather than publishing its own content. EHow, a site that started in 1999 with text-only content, contains over 100,000 instructional articles submitted by its users or eHow editors, and has a small catalog of videos.

Howcast videos can be seen in full-screen mode using a player that illustrates step-by-step text instructions beside video screens.

After testing each of these sites, I found that my favorite how-to videos had steps that were clearly labeled and numbered and the ability to fast forward to or play back specific parts in the video — tools that Howcast included in almost all of its videos. At least some of the videos on the three sites simply illustrate things you could likely figure out how to do without watching a video, such as “How to Make Green Beer.” (Add food coloring.) Howcast.com and WonderHowTo both require users to sign in, which confirms their date of birth, before looking at what they consider “mature” content.

These three free sites are advertisement-supported, and Howcast’s ads run alongside videos. WonderHowTo.com runs ads at the top and side of its own site, on which it will play certain videos. But because videos on WonderHowTo come from other sources, those other sites can show video-embedded ads according to their rules. EHow’s videos run pop-up text advertisements displaying names and links of other related (and sometimes unrelated) Web sites. But I couldn’t get the pop-up ads to stay closed.

Overall, I preferred the look of Howcast’s site and its well-organized videos. But its content paled in comparison to WonderHowTo’s 110,000 videos and even eHow’s 100,000 instructional articles. WonderHowTo.com does a nice job of gathering content from across the Web, though the inconsistencies of other sites (including advertisements, layout and video player) were a bit frustrating. EHow’s articles were useful, as were its few videos, but I couldn’t get over the site’s unyielding video pop-up ads.

Howcast.com’s content was informative with an amusing edge, including a video titled “How to Tell If Your Boyfriend’s A Psycho.” (If he calls 50 times a day, for example.) Other videos on the site are more serious, like “How to Make Sushi” by an executive sushi chef in New York City.

The founders of Howcast Media formerly worked in Google’s (GOOG) video department, including during the acquisition of YouTube. All of Howcast’s content comes from one of four sources: written and produced by Howcast in its studios; emerging filmmakers who apply and are accepted into the Howcast Directors Program to receive $50 a video and 50% of the advertising revenue generated from videos that generate over 40,000 views on the site; content partners like Popular Science; and Howcast users’ personal how-to videos.

In order to make it easier for average users to upload better-looking videos, Howcast provides an Upload and Enhance tool that simply and quickly adds professional-looking graphics and printable steps to go along with how-to videos. This formula makes videos more enjoyable to watch.

Videos made in the Howcast Studios include accompanying music, good narratives and actors who add humor to an otherwise humdrum how-to. Among its helpful features is a video player that has smart blue markers to show where facts are sprinkled throughout the video and green markers to illustrate where tips appear. For example, the fact at the end of a video for beginner guitarists called “How to Play a Basic Bar Chord” is “The late Kurt Cobain claimed he was trying to rip off the Pixies when he wrote ‘Smells Like Teen Spirit. ‘” In full-screen view, users can zoom in on any part of a video, and written-out steps and thumbnail stills of the scene appear to the right of the screen.

Howcast tries to run ads alongside videos that relate to the content. A video titled “How To Clean Your Dog’s Teeth” has an ad for PetSmart (PETM) Stores running on its page.

WonderHowTo.com was developed by a former television executive with the intention of using the site to produce its own video, like Howcast.com. Instead, WonderHowTo.com opted to tap the vast selection of how-to videos already available on the Web.

A Browse button pulls down 35 categories from which users can sort content, including Spirituality, Dating & Relationships and Fitness. In the Fashion subcategory under Beauty & Style, I found 290 videos including one on “How to Tie a Windsor Knot” and another titled “How to Turn Old Underpants Into a Bra” — neither of which I’ll be using anytime soon. Other categories include Clip of the Day, Recommendations (for users who are logged in) and Fresh, where new videos are listed. Users can grade videos to help others tell which they think are the best, and a Top Grade category compiles the top-ranked videos.

WonderHowTo’s content comes from over 700 sites, according to the company. I used the site to find a video on YouTube about how to do a front-flip, clips on VideoJug.com that provided terrific tennis tips from a coach, and a video from EasyBarTricks.com about how to stick a beer bottle to a wall without glue or gum. (Hint: You’ll need a corner and a wall you don’t mind marking up.) WonderHowTo made it easier to find these videos than by performing a general search on the Web.

I submitted a non-how-to video to this site by simply entering a URL, without logging in. I never found the video I submitted on the site; WonderHowTo explained that it screens all videos prior to posting them, so it must have found my video.

EHow.com uses its database of articles to encourage people to watch videos, when they’re relevant. This site uses calm, pastel colors to give a relaxed feeling — especially compared with WonderHowTo, where banner ads surround the page. EHow’s 26 categories include Parenting, Parties & Entertaining and Weddings. Twelve subcategories within Weddings led to 23 articles about Bridal Party Responsibilities — a popular topic was “How To Deal With a Bridezilla.” Related videos, such as “How To Get Rid of Wedding Day Jitters,” ran along the right of the page.

Videos can also be found on eHow within a marked tab at the top of the page. But unlike the articles on eHow, these videos weren’t well organized or as easily searchable. I watched one of eHow’s Featured Videos called “How to Know if Your Toe Is Broken,” but after closing a pop-up ad for UPS (UPS) during Step One of the video, another ad popped up during Step Five. Neither ad had anything to do with broken toes.

But the eHow videos were professional-looking and included quite a few tips that I didn’t know. That broken toe video was submitted by the eHow Health Editor, and a link at the top of the page led me to hundreds of other health-related articles. I found another video on “How To Remove Wallpaper,” which was posted by the Home & Garden Editor and included a list of things I would need to proceed, along with numbered steps.

It isn’t always easy to learn from the information you find online, and how-to videos can be a big help — especially when they’re well-made and easy to find using one of these sites. Howcast.com has well-presented content that was enjoyable to watch, but WonderHowTo.com offers a better variety of instructional videos.

Tubes installs a program on the desktop (right) into which files can be dragged and shared using automatic synchronization.

This week, I tested another product in the long line of programs that uses automatic synchronization to simplify the process of sharing large files by giving you the ability to change files and privacy options at any time. It’s called Tubes (www.tubesnow.com) from Tubes Networks and it takes its name from the pneumatic vacuum-tube system commonly used in bank drive-throughs that motivated me to join my Mom on visits to the bank as a kid. Mom would pull up and a container would whoosh over through a tube to arrive beside the car window; after a quick exchange it returned with her deposit slip and a lollipop for me.

Tubes aims to work with the same sort of magic. Once installed, its desktop application stays opened on your computer as a place where “tubes” are made for sending files. Any type of file can be dragged, dropped and sent off to share with other people using these virtual tubes. As soon as you release data into a tube, a whoosh sounds (like that of the vacuum tube) and your files are encrypted and uploaded to the Tubes server.

Invited guests view your tube’s data in its full, uncompressed format. The owner of the tube always has the final say on what is shared with whom, and changes made to tubes on your hard drive are detected instantly via automatic synchronization, guaranteeing viewers will always see the latest version of the tube. Shared tubes are also accessible via the Web, saving viewers from downloading the Tubes desktop program.

Other products like Sharpcast (www.sharpcast.com) and Pando (www.pando.com) also offer ways to share large digital files; Sharpcast uses synchronization similar to that of Tubes — it all happens behind the scenes without any work on the user’s part.

Tubes is available in a free version that provides a gigabyte of storage, or in paid versions with five, 10 and 20 gigabytes of storage for $6, $11 or $21, respectively.

Most of the time, Tubes worked well for me when I installed it on two Windows machines, one running XP and one running Vista. Tubes’ smart use of an already familiar process — dragging and dropping — gives you the impression that you already know how to use it and makes sharing files seem easy. I started dragging all sorts of files into tubes that I created, naming them and labeling them with a representative icon (one of 10 offered by Tubes or one of my own images).

For all its usefulness, Tubes certainly has room for improvement. For now, there isn’t a Mac version of the program, and when friends and I tried accessing shared tubes using a Mac Web browser, the results were inconsistent and sometimes didn’t work at all. Windows Vista had its own issues. After installing Tubes on my Vista laptop, an error message labeled “invalid argument” made me feel like a member of the debate team. And I couldn’t see thumbnail images of photos in my tubes using Vista, though I could on Windows XP.

Today, Tubes is releasing an updated version of its program that aims to improve the usability and look of the product, including refining the processes of sharing tubes and looking at tubes via the Web.

Before sharing tubes, I adjusted the permissions granted to each guest by labeling them as a Reader, Author or Editor; only the Owner can invite others to view a tube. But these labels can get confusing. More than once, I granted guests the highest level of permission, which is Editor, allowing them to make changes to the files in my tube, only for the guest to be asked for his registered Tubes email and password, which an invited guest shouldn’t need.

The Tubes experience was best when the recipient of my Tubes invitations had the application installed on his or her desktop.

After installing Tubes on a computer at work, I installed it on my home PC and easily auto-synched tubes that I created at work onto my home PC — a big plus.

Tubes incorporates the Web by assigning a unique URL to every file in every tube, and every tube automatically generates its own Web site, or “tubeSite,” as it’s called. Individual URLs for each file can be found by right clicking on a file and selecting an option to copy the URL into an email or browser. I copied the URL of a shared MP3 audio file and pasted it into my browser; it played a Fountains of Wayne song with no problem. But sharing these URLs with others is only possible if the owner gives permission.

Comments about tubes can be made in the “tubeBlog” — accessible through any tube in the application or online. I created a tubeBlog for a tube with photos from one of my vacations, adding descriptions and comments to specific photos. Others, with my permission, could do the same, using the photos from the tube or just leaving comments.

A friend used Tubes to share photos with me while vacationing in Italy and Amsterdam. I added my own travel photos and an itinerary made in Microsoft Word to his tube and changed the tube’s title; these alterations synched instantly.

Even if you aren’t online, you can access tubes or make changes to them by dragging files in or taking them out; updates are made automatically the next time your computer connects to the Web.

Tubes is off to a good start, but it needs to improve its system to make permission levels more understandable for tube owners and those invited to see a shared tube. With a few improvements, Tubes could be a product that I’ll continue using on Windows computers long after this column.

Apple’s new iMac comes loaded with iLife ’08 software.

But Apple‘s bigger change was a major update to its iLife software suite, which comes loaded on all its Macintosh models — not just the new iMac — and can be purchased by existing Mac owners for $79. The suite includes iPhoto, iMovie, iDVD, iWeb and GarageBand — programs that help average people organize, edit, share and publish photos, videos and music. These uncluttered and intuitive programs have been best of breed, so Apple’s decision to update iLife is intriguing, if for nothing other than to see what major improvements could really be made.

This week I tested iLife ’08 on a new iMac — the midrange $1,499 20-inch model with a 2.4 gigahertz Intel Core 2 Duo processor and a 320-gigabyte hard drive. I focused especially on iPhoto and iMovie, the anchors of the suite and the programs that got the biggest overhauls. One significant change in iPhoto is its new method of organizing photos by sorting images into “Events” according to their dates, rather than by the batch in which they were uploaded to your computer. The iMovie program underwent a more drastic overhaul, adding a library for storing all of your video clips and a new interface for organizing those clips into a movie that dispenses with the traditional timeline design long used in digital video software.

Both iPhoto and iMovie now use “skimming,” a rich feature that lets you scan through photos or videos just by passing your cursor over a thumbnail. And if you have an account on Apple’s online .Mac service ($100 annually), both programs offer effortless one-click photo or video uploading to a “Web Gallery,” where you can share your content. Videos can also be uploaded directly to YouTube without a .Mac account.

Before delving into the software, a quick word about the new iMac is in order. It’s an improvement on an already stellar computer, with beefed-up specs. There are four models, from $1,199 to $2,299, in two screen sizes — 20 inches and 24 inches. The base 20-inch model costs $1,199, a price cut of $300 from the prior 20-inch model. The base 24-inch model now costs $1,799, down $200 from the old model of the same size.

The biggest adjustments for users will be the screen and keyboard, which took me a few days to get used to. The new iMac comes with a glossy screen, which makes colors pop but also reflects more background light than a traditional matte display.

Radical Keyboard

The keyboard is radical-looking. It’s much flatter and sleeker than typical desktop PC keyboards. I found it easier to type with, but in an attempt to make it more like that of a laptop keyboard, Apple rearranged some built-in key functions, which was confusing at first. If you hate it, you can still use an older Mac keyboard or any USB keyboard, even those meant for Windows computers. For now, the new iMac offers only a wired keyboard. A small wireless model is due in a few weeks.

I quickly picked up on how to use the new features in iPhoto and iMovie, thanks to unintimidating, self-explanatory icons. The Events feature in iPhoto might be a pain for users who are transferring numerous already-organized albums from the previous version of iPhoto into this one, as not all albums will perfectly translate into Events. But it’s a great improvement over the old method — and over Windows photo programs I’ve tried — for organizing newly shot photos.

The new version of iPhoto will look familiar to anyone who used the older version; its layout is the same, with a list of your photo library on the far left and a large display area to the right of this list. I uploaded a couple of albums at once, and each was automatically sorted into its own event because the photos from each were associated with two different dates.

Skimming the Thumbnails

A few new features stand out at a glance. When photos are grouped into Events, these are neatly marked with one large thumbnail image that is selected to represent the entire pile of photos. By passing my cursor over this top thumbnail, I skimmed through all of the images in that Event in mere seconds. A button labeled Web Gallery instantly uploads images to a .Mac account, and a list of photos that are shared online appears in iPhoto.

The updated iPhoto automatically groups photos into Events represented by thumbnails that make for faster photo browsing.

Rather than deleting images that I didn’t want in a particular Event, I selected the new Hide icon, which takes marked images away from view but notes the number of hidden photos at the top of the Event as a reminder. Hidden photos can also appear within the Event, denoted with red X marks.

Double clicking on any image now magnifies it without opening editing functions, letting users quickly see larger versions of each shot. Editing in iPhoto was already straightforward, but new options provide more customization; for example, red eyes can be removed with a cross hairs (like the old iPhoto) or by using a circle that manually adjusts to match a subject’s pupil size.

The new version of iMovie is deliberately designed to steer away from the familiar interface most consumer video-editing programs use, which was borrowed from professional-grade software. Instead of the usual timeline of clips, iMovie employs a more free-form canvas where clips and effects can be assembled. Apple knows that this may irk people used to the traditional method, but believes it will make video editing much less intimidating for casual users.

To test iMovie, I used a high-definition Panasonic video camera to capture amusing moments around my office and brought it with me to Boston for three days so I could document my sister’s move into her new place (the moving guys were thrilled). In both places, I turned the camera on and off numerous times, capturing short clips.

Instant Recognition

My video camera was instantly recognized when I plugged it into the iMac, prompting iMovie to generate thumbnail images of each clip. Times when the camera was turned on or off were clearly marked, and I chose the clips I wanted to import. Transferred content appeared in the new iMovie library at the bottom half of a screen, and I dragged and dropped clips to the top half of the screen to add them to a project. Clips can be selected by using your cursor to draw a yellow box around the whole clip or just a part of the clip that you’d like to use. Skimming through content is helpful here — as I moved my cursor from left to right through clips, the audio and video played in the top right of the screen, letting me see and hear footage so as to select exactly where to trim a clip.

The new interface for iMovie is more approachable for everyday users, with a smart library that organizes Projects and Events into two different libraries.

After dragging various clips to the top half of the screen, I added special features like music, sound effects and title slides to my project. These were all added the same way my clips were: by dragging and dropping to put the right thing where it needed to go. Music from iTunes can be used with videos, or Apple provides over 500 different sound effects and tunes.

Still photos can be incorporated into iMovie using a “Ken Burns” effect (panning across a still image) to keep the video’s pace moving along. And any videos captured on a digital camera that were uploaded into iPhoto can be retrieved and used from within iMovie. If footage is too dark, it can be automatically or manually adjusted, like images in iPhoto.

Polished Results

In just about 15 minutes, I created a short movie that mashed together various clips from three days of moving. I added titles to introduce the movie, and transitions in between each clip that looked really polished.

I uploaded photos and videos to the .Mac Web Gallery, checking off the privacy option (passwords can be set to limit who sees the content). Other options to check include showing titles of photos; enabling a feature that lets others upload images to my gallery via a set email address; and letting other people download high-resolution versions of my content. In one step, videos can also be uploaded to YouTube.com or transferred to your iTunes library, where they can be viewed on a PC or Mac, or moved over to an iPod or iPhone.

The new programs in iLife ’08 are a pleasure to use, and the new iMac is a great way to experience them.
