VisualHub was a very popular OS X application to convert video files to any number of formats, including optimizing video for iTunes, WMV, or Flash. In 2008, Tyler closed the company and stopped selling or supporting VisualHub or Techspansion's other products.
When VisualHub broke with the release of Lion, Loch released a very slight tweak that would allow VisualHub to work once more, but required some technical knowledge to implement. Techspansion's old payment processor, Kagi, began selling a $5, unauthorized, Lion updater for VisualHub that implemented the same fix, but in a much more user-friendly manner.
Loch was very upset with this unauthorized use of his code, and was especially displeased because Kagi used his old customer records to email every user who had purchased VisualHub through them. Once Loch expressed his unhappiness, Kagi stopped selling the update and Loch released the last official update for VisualHub on his website, with this note:
It's been nearly three years since Techspansion closed and these programs were last maintained.
VisualHub and AudialHub are no longer supported. And they won't last forever. Whatever breaks from here on out will be the end, sadly. I hope this update squeezes a little more life out of these two apps for you.
