Testing Video Search Engines


Posted by Joseph Devlin

We all know the web is sloshing full of digital video. How can you find just the right video in an ocean full of choices? Opinions about which video search tools work best vary widely. So I decided to create a quick test to provide a more objective measure of success.

I started by compiling a list of the video search tools I had seen other bloggers recommending.  Next I created a list of specific videos I wanted each tool to look for.  I asked each tool to look for each video using search terms that worked well on the service that hosted that video.

 Following is a listing of the five videos I was looking for, the search terms I used, and an explanation of what I was looking for:

  • Doraemon Happy Meal McDonald's - A Japanese McDonald's commercial I found on YouTube.
  • IBM and the Future of Movies - An episode of one of the best- known corporate video podcasts. Hosted on IBM’s servers.
  • Joe Devlin, Rick Prelinger explains - An interview I posted a few days ago on Google Video for this blog.
  • San Francisco Urban Iditarod - A fake sled dog video I posted as a test almost two years ago on several on-line sites. Six months ago it showed up on the front page of the official SF Urban Iditarod MySpace page.
  • Battlestar Galactica, The Road Less Traveled - An episode of a popular TV show that can be viewed off Hulu.com and AOL Video.

My rating for each search engine (1 star for each correct hit of my five test videos.)

SPECIALIZED VIDEO SEARCH ENGINES
(These are supposed to crawl the web looking specifically for all sorts of video content) Truveo does great job as a vide search engine

Truveo                        *  *  *  *  *
Truveo found all five of the videos I searched for right away and presented the results so that each video could be played with a click of the mouse. It also provided lots of different ways to search (i.e. top ranked, most viewed, most viewed today, most recent, most relevant, etc.)

AOL Video                  *  *  *  *  *
http://video.aol.com/video-search
Results of this search looks almost identical to a Truveo search. This is no surprise since Truveo powers the AOL Video search these days. Going throug AOL provides a smaller selection of search choices than a pure Truveo search, so maybe the correct ranking should be four and half stars.

Blinkx                          *  *
A big disappointment. Blinkx gets mentioned by a lot of bloggers as their favorite video search tool. It found my Google Video/ Prelinger video and the right Battlestar Galactica show on Hulu.com. It also found 890 McDonald's videos using my search criteria and 83,000 IBM videos, but in each case the specific video I was looking for was not listed in the top 20 selections.

SearchforVideo          *
Lets you sort by date or relevance but produced awful results. The only one of the searches it completed correctly was for my Prelinger interview. Unfortunately the first result for the Prelinger search was "G Unit Rapper Lil Scrappy explains his blonde hair phase..." My Video was the 31st video listed. One star may be too high a rating.

Fooooo                        *  *
A Japanese video search engine ported to English, Russian, Chinese and French about a year ago. It found the two videos hosted on YouTube but nothing else.

SEARCH TOOLS BUILD INTO AGGREGATION SERVICES
(Video search tools built into video hosting or aggregation sites)

YouTube                       *
I know, I know, YouTube hosts the lions share of web video and can find everything it hosts. But the built-in search engine does a terrible job finding anything not hosted on YouTube. It found the YouTube McDonald's commercial, but from what my tests show nothing else. It did not even find the video hosted on sister site, Google Video.

iTunes                          
I love iTunes, but I find that the iTunes search tools get harder to use with each new release. The iTunes podcast directory search tool found the IBM video podcast, but I know the service well. I suspect most people would not even find that. The main iTunes search tool found some older episodes of Battlestar Galactica, but new episodes of the show have moved to Hulu.com and AOL video and were not listed in iTunes.

Google Video Search   *  *  *
The search engine built into Google Video did a better job than the YouTube search engine. It found the two videos hosted on Google Video and the McDonald's video hosted on sister site YouTube. It found promos for the TV show, but not the episode itself.

Hulu.com                       *
If you haven't tried Hulu.com you are missing a great free video on demand service. Hulu  offers free streaming video of more than 400 TV shows and movies, primarily from NBC and FOX and affiliated cable networks (USA Network, Bravo, Fuel TV, FX, Sci Fi, Style, Sundance, G4, and Oxygen). The video it offers is also much higher resolution than found on YouTube. On the other hand, the built-in search engine only finds Hulu content (such as the Battlestar Galactica show I was looking for.)  Hence the low rating as a general purpose video search engine.

GENERAL SEARCH TOOLS
Google                            *  *  *  *  *
Almost a year ago I was meeting with a client, a large publisher of video podcasts. I advised him to pay closer attention to what Google was revealing about his podcasts. "Joe you just don't get it" he told me. "Google does not index podcasts".

"Not entirely true" I told him. "Google has got some skunk projects that are starting to look closely at video feeds. More importantly Google crawls almost every website. If you are offering video that is fed from an Internet landing page or if you include show notes about a video on the web,  your casts are going to be found by Google." He argued I was being dense until I asked him to do Google search on one of his episodes.

"See" he beamed at me "look at the terrible results Google is providing. It has found all this old screwed up material we fixed long ago and lots of comments critical of my podcasts. I don't want anyone to see any of this stuff!."

"And what are they seeing when they do a Google search" I asked.
"Oh" he said and spend the next hour yelling at his webmaster.

It is certainly true that a plain vanilla Google search does not provide as good a video search as Truveo does. Yes, Google found every video I asked it to find, but it also returned lots of other related info.   If you run a business that uses on-line video, you need to keep tabs on what sort of results straight Google searches produce.  If you are looking for video and only video, you are probably better off using Truveo. The interface is streamlined for video and it provides a variety of search criteria not available in a straight Google search.
