How to convert Voki to Youtube for Prezi

It turned out this was a bit harder than I thought it would be. The Voki product doesn’t seem to be flash, or at least there was no trace of a flash file in the Firefox cache.

Video capture

I used Jing for a video capture of the Voki video, but this created an swf file which I wasn’t able to convert into anything usable.  This was surprising, because I could play the swf file using Firefox, but there still wasn’t anything in the cache.    I then tried Screenr and this generated a local flv file, which I was able to use.

I converted the flv file to wmv using VLC but the quality was poor; especially the first part of video was garbaged. I then tried converting using  Lumixsoft FLV to WMV converter  This gave a much higher quality conversion.  The wmv file was uploaded into Windows Movie Maker.

Audio capture

Neither Jing nor Screenr picked up the audio.  I was able to capture this using NCH’ Soundtap Streaming Audio Recorder.  This generated a wav file that I could  uploaded into Windows Movie Maker.  The sound was synchronized with the video manually and the product saved as a wmv file, then uploaded to Youtube, then the embed code was pasted here via Vodpod:

Vodpod videos no longer available.

There appears to be some loss of both video and audio quality through these manipulations.

Dressing up Xtranormal

I dressed up an Xtranormal video by:

  • extracting the flv from the cache
  • loading it into VideoPad Video Editor.
  • To add  music, I converted  an mp3 file into wav format in WavePad and uploaded the wav file into VideoPad.
  • I created an intro sequence by taking snapshots from the Xtranormal sequence and then added a voice track to the “intro”.
  • Uploaded to Youtube.

Note:In VideoPad you can adjust the volume for each audio track separately.  I couldn’t figure out how to adjust the volume of  mp3 files in VideoPad, but it worked easily for wav files.  Here’s the product: “Lives of the Hunted. Episode 1”:

You can recover flash (Youtube, animoto, etc) files you’ve played in Firefox by finding them in the cache.(In fact, almost any file that is displayed by Firefox can be recovered from your cache). It’s not too hard:

  1. Clear the cache
  2. play the flash file
  3. Find out where your cache is.
  4. Find the file in the cache
  5. Add the proper extension, rename it and move it to where  you want.

First, clear the cache under Tools/Clear Recent History .  Click on “Cache” and clear it.  You do this because usually your cache is so full of junk that you’ll have trouble finding what you want.

Second,  play your flash file.  This will place a new copy of the flash video in your cache.

Third, find the cache. You do this by typing “about:cache” in the URL window of Firefox:

Copy and paste the path to the disk cache device into Explorer (not Internet Explorer!).

Now you need to find the flash video file.  Note that all the entries in your cache end with “d01” and have no extensions.  You’ll recognize the file you want because it will be “large” and recent.

Rename it to add a “.flv” extension (see image on right).

(Note that things will go easier if you have set your folder display to show all extensions).

Your system should recognize it it has a flv player registered.  In my case, I have VLC player registered to play flv, so the icon for VLC shows up.  Double-click to see if it plays the correct thing.  If not, then carefully rename it back to what it was and try a different file.

If it is the correct one, then name it whatever you want and move it to a desired directory.

Adding Voice over image to Prezi using Logitech webcam and Youtube

This diagram was  made by

    • posting  local images to using TweetDeck
    • creating the map in VUE with  local images and embedded links to URL for the flv and Prezi.
    • letting VUE create HTML and associated png file  for the map shown above .
    • obtaining the html code from VUE  via CTRL-U from the browser
    • pasting the last “body” from the code into the blog.
    • sending the png to  yfrog and replace the local png address with the yfrog URL.
    • replacing local image links with yfrog links (This is necessary because VUE can’t display two links (eg. thumbnail and URL) simultaneously.

Use of VoiceThread

We consider briefly three theoretical frameworks: Knowle’s theory of adragogy, constructivism, and  Wedmeyer’s Theory of Independent Study

My collaborators for this voicethread production were the very cool Emily Vinas and Joyee Vachani.  We used Tokbox to provide audio/video and IM commmunication while we collaborated using Google Docs to produce the initial presentation used as input for VoiceThread. At times it seemed we were in a Rod Serling production, but that was when my mike was generate too much feedback.

Review of eyeplorer

Synopsis of Review: EyePlorer is a really cool tool for seeing a subset of conceptual connections in Wikipedia. It is a “reverse concept mapper” in that EyePlorer starts with a map of terms, and shows the viewer the major terms, leaving the viewer to decide if there is an important conceptual connection between terms. I have found it useful in identifying links I would not have picked up in standard search engines. There are a few caveats:
1. The “intellectual commons” used by EyePlorer is Wikipedia only.
2. EyePlorer doesn’t seem to be able to pick related terms if there is more than one degree of separation between them.
3. EyePlorer doesn’t seem to be able to pick up connections between two ideas UNLESS they are in the same sentence.

None of these caveats are really surprising, but EyePlorer should really be thought of as another kind of search engine, not really a “concept mapper”.


8/15/2010.  EyePlorer does look at adjacent sentences, or sentences in the same section within a Wiki article, at least.  This might be the function of the secondary search terms- to look at entries within the primary search term, which corresponds to Wikipedia article names, that have the secondary search term somewhere in the article (?).  A spot check of some instances supports this model of their search engine.  If so, the secondary search term is a way of reducing the number of entries, functioning as Boolean AND.


I had many technical problems putting this together. I wanted to accomplish the following in this review:
1. use a non-linear Prezi-presentation.
2. stand-alone using voice.
3. an edited voice-over technique to avoid the hems and haughs I usually have.
4. A speaking avatar

1. The resolution of the Youtube files at least as viewed through Prezi are terrible.
2. The Voki avatar worked but (1) I don’t like the advertisement that Voki has with the free version. There is an educator’s version though that might avoid that. The video resolution wasn’t good. Screenr and Jing wouldn’t pick up the audio off the web, so I had to jump through a few hoops to create the youtube file.
3. The mixed-media with edited voice-over for the “Concept of EyePlorer” involved recovery of a captured videocast and assembly using Microsoft MovieMaker and WavePad Sound editor.

4.  The “Demo” segment involved quite a few unedited sessions with Screenr but I could post it directly to Youtube.

5. The “Caveats” segment used Screenr to capture unedited video capture using VUE (demonstrating its flexible links), OneNote, and EyePlorer in “one-take”.
